? 2010 microchip technology inc. ds22230c-page 3 mcp2003/4 1.0 device overview the mcp2003/4 provides a physical interface between a microcontroller and a lin bus. this device will translate the cmos/ttl logic levels to lin logic level, and vice versa. it is intended for automotive and industrial applications with serial bus speeds up to 20 kbaud. lin specification 2.1 requires that the transceiver of all nodes in the system is connected via the lin pin, refer- enced to ground and with a maximum external termination resistance of 510 ? from lin bus to battery supply. the 510 ?? corresponds to 1 master and 15 slave nodes. the v ren pin can be used to drive the logic input of an external voltage regulator. this pin is high in all modes except for power-down mode. 1.1 external protection 1.1.1 reverse battery protection an external reverse-battery-blocking diode should be used to provide polarity protection (see example 1-1 ). 1.1.2 transient voltage protection (load dump) an external 43v transient suppressor (tvs) diode, between v bb and ground, with a 50 ? transient protection resistor (r tp ) in series with the battery supply and the v bb pin serve to protect the device from power transients (see example 1-1 ) and esd events. while this protection is optional, it is considered good engineering practice. 1.2 internal protection 1.2.1 esd protection for component-level esd ratings, please refer to the maximum operation specifications. 1.2.2 ground loss protection the lin bus specification states that the lin pin must transition to the recessive state when ground is disconnected. therefore, a loss of ground effectively forces the lin line to a high-impedance level. 1.2.3 thermal protection the thermal protection circuit monitors the die temperature and is able to shut down the lin transmitter. there are two causes for a thermal overload. a thermal shut down can be triggered by either, or both, of the following thermal overload conditions. ? lin bus output overload ? increase in die temperature due to increase in environment temperature driving the t xd and checking the r xd pin makes it pos- sible to determine whether there is a bus contention (rx = low, tx = high) or a thermal overload condition (rx = high, tx = low). after a thermal overload event, the device will automatically recover once the die tem- perature has fallen below the recovery temperature threshold. see figure 1-1 . figure 1-1: thermal shutdown state diagram operation mode transmitter shutdown lin bus shorted to v bb te m p < shutdown temp
mcp2003/4 ds22230c-page 4 ? 2010 microchip technology inc. 1.3 modes of operation for an overview of all operational modes, refer to table 1-1 . 1.3.1 power-down mode in power-down mode, the transmitter and v ren are both off. only the receiver section and the wake-up circuits are operational. this is the lowest power mode. on bus activity (e.g. a break character), cs going to a high level, or on a falling edge on wake, the device will immediately enter ready mode. if cs is held high as the device transitions from power-down to ready mode, the device will transition to operation mode as soon as internal voltages stabilize. 1.3.2 ready mode upon entering the ready mode, v ren is enabled and the receiver detect circuit is powered up. the transmit- ter remains disabled and the device is ready to receive data but not to transmit. upon vbb supply pin power-on, the device will remain in ready mode as long as cs is low. if cs transitions high, the device will enter operation mode. however, if the t xd pin is held low when cs goes high, the device will transition to transmitter off mode instead of operation mode. 1.3.3 operation mode in this mode, all internal modules are operational. the mcp2003/4 will go into the power-down mode on the falling edge of cs. the mcp2003/4 will enter transmitter off mode in the event of a fault condition. these include: thermal overload, bus contention and t xd timer expiration. the mcp2004 device can also enter transmitter off mode if the fault /txe pin is pulled low 1.3.4 transmitter off mode transmitter off mode is reached whenever the transmitter is disabled either due to a fault condition or pulling the nfault/txe pin low on the mcp2004. the fault conditions include: thermal overload, bus contention or txd timer expiration. the mcp2003/4 will go into power-down mode on falling edge of cs, or return to operation mode if all faults are resolved and the fault /txe pin on the mcp2004 is high. figure 1-2: operational mod es state diagram ? mcp2003 note: bus activity is defined as lbus dropping below v il (l bus ) for longer than the bus activity debounce time (tbdb) operation mode vren on rx on tx on ready mode vren on rx on tx off toff mode vren on rx on tx off power-down mode vren off rx off tx off vbat > 5.5v cs = 1 and txd cs = 0 cs = and txd = cs = 0 falling edge on lin or cs = 1 cs = 1 and txd = 1 and no fault fault (thermal or timer) por vren off rx off tx off

mcp2003/4 ds22230c-page 8 ? 2010 microchip technology inc. 1.5 pin descriptions table 1-1: pinout descriptions 1.5.1 receive data output (r xd ) the receive data output pin is a open drain (od) output and follows the state of the lin pin. 1.5.2 cs (chip select) chip select input pin. an internal pull-down resistor will keep the cs pin low. this is done to ensure that no disruptive data will be present on the bus while the microcontroller is executing a power-on reset and an i/o initialization sequence. the pin must detect a high level to activate the transmitter. if cs = 0 when the v bb supply is turned on, the device stays in ready mode. in ready mode, the receiver is on and the lin transmitter driver is off. if cs = 1 when the v bb supply is turned on, the device will proceed to the operation mode as soon as internal voltages stabilize. this pin may also be used as a local wake-up input (refer to example 1-1 ). in this implementation, the microcontroller i/o controlling the cs should be converted to a high-impedance input allowing the internal pull-down resistor will keep cs low. an external switch, or other source, can then wake-up both the transceiver and the microcontroller (if powered). 1.5.3 wake up input (wake ) this pin is only available on the mcp2003. the wake pin has an internal 800k pull up to v bb . a falling edge on the wake pin causes the device to wake from power-down mode. upon waking, the mcp2003 will enter ready mode 1.5.4 fault /txe this pin is only available on the mcp2004. this pin is bidirectional and allows disabling of the transmitter, as well as fault reporting related to disabling the transmitter. this pin is an open-drain output with states as defined in ta b l e 1 - 2 . the transmitter is disabled whenever this pin is low (? 0 ?), either from an internal fault condition or by an external drive. while the transmitter is disabled, the internal 30 k ? pull-up resistor on the l bus pin is also disconnected to reduce current. pin name 8-pin pdip, soic 8-pin dfn mcp2003 mcp2004 normal operation normal operation r xd 1 1 receive data output (od) receive data output (od) cs 2 2 chip select (ttl) chip select/local wake (ttl) wake (mcp2003 only) fault/txe (mcp2004 only) 3 3 wake up, hv tolerant fault detect output (od) transmitter enable (ttl) t xd 4 4 transmit data input (ttl) transmit data input (ttl) v ss 5 5 ground ground l bus 6 6 lin bus (bidirectional) lin bus (bidirectional) v bb 7 7 battery positive battery positive v ren 8 8 voltage regulator enable output voltage regulator enable output ep ? 9 exposed thermal pad. do not electrically connect or connect to vss exposed thermal pad. do not electrically connect or connect to vss legend: ttl = ttl input buffer; od = open-drain output note: it is not recommended to tie cs high as this can result the mcp2003/4 entering operation mode before the microcon- troller is initialized and may result in unintentional lin traffic. note: the fault /txe pin is true (? 0 ?) whenever the internal circuits have detected a short or thermal excursion and have disabled the l bus output driver.
? 2010 microchip technology inc. ds22230c-page 9 mcp2003/4 table 1-2: fault/ txe truth table 1.5.5 transmit data input (t xd ) the transmit data input pin has an internal pull-up. the lin pin is low (dominant) when t xd is low, and high (recessive) when t xd is high. for extra bus security, t xd is internally forced to ? 1 ? whenever the transmitter is disabled regardless of external t xd voltage. 1.5.5.1 t xd dominant timeout if t xd is driven low longer than approximately 10ms, the lbus pin is switched to recessive mode and the part enters toff mode. this is to prevent the lin node from permanently driving the lin bus dominant. the transmitter is re-enabled on t xd rising edge. 1.5.6 ground (v ss ) this is the ground pin. 1.5.7 lin bus (l bus ) the bidirectional lin bus pin (l bus ) is controlled by the t xd input. l bus has a current limited open collector output. to reduce emi, the edges during the signal changes are slope controlled and include corner rounding control for both falling and rising edges. the internal lin receiver observes the activities on the lin bus, and matches the output signal r xd to follow the state of the l bus pin. 1.5.7.1 bus dominant timer the bus dominant timer is an internal timer that deac- tivates the l bus transmitter after approximately 25 milliseconds of dominant state on the l bus pin. the timer is reset on any recessive l bus state. the lin bus transmitter will be re-enabled after a recessive state on the l bus pin as long as cs is high. disabling can be caused by the lin bus being externally held dominant, or by t xd being driven low. additionally, on the mcp2004, the fault pin will be driven low to indicate the transmitter off state. 1.5.8 battery (v bb ) this is the battery positive supply voltage pin. 1.5.9 voltage regulator enable output (v ren ) this is the external voltage regulator enable pin. open source output is pulled high to v bb in all modes, except power down. 1.5.10 exposed thermal pad (ep) do not electrically connect, or connect to vss. t xd in r xd out lin bus i/o thermal override fault/ txe definition external input driven output lhv bb off h l fault, t xd driven low, lin bus shorted to v bb (note 1) hh v bb off h h ok l l gnd off h h ok h l gnd off h h ok, data is being received from the lin bus xxv bb on h l fault, transceiver in thermal shutdown xxv bb x l x no fault, the cpu is commanding the transceiver to turn off the transmitter driver legend: x = don?t care note 1: the fault /txe is valid after approximately 25 s after t xd falling edge. this is to eliminate false fault reporting during bus propagation delays.
