MC145576EVK
I. Introduction The MC145576EVK board has been designed to demonstrate and evaluate the Motorola single chip NT1 solution based on the FLINT (MC145576). The MC145576 is configured by default to work in a standard NT1 mode (see section III), this configuration can be changed to provide a terminal access to the MC145576 which is required for the SMART NT1 applications (see section IV). This terminal access can be IDL/SCP or GCI. The MC145576EVK board is powered by an external 5V power supply, there is no power feeding circuitry which recovers the power from the U line. Another connector can be used to provide +40V power supply down to the TE through the S/T line (+40V and +5V power supplies have separated grounds).

III. MC145576 in NT1 mode In the NT1 mode, as there is no terminal access required and where the minimum possible power consumption is desired, the MC145576 will provide a U and S/T analog interfaces and some configuration and indication pins. Switchs configuration: CLK_SEL ENO_L LED2 LED1 CLASS/ECHOIN FIX no function OFF (logic high) ON ON no function OFF Fix mode, ON Adaptative mode

ON (GCI mode) OFF see note OFF PS1=1, ON PS1=0 OFF PS2=1, ON PS2=0 OFF /Pulse1=1, ON /Pulse1=0 OFF /Pulse2=1, ON /Pulse2=0
Note: If Activation Request DRQ_AR need to be used, ENO_L should be switch ON.
IV. FLINT in Smart NT1 mode In the Smart NT1 mode, the terminal access is required. This terminal access, plus some control and indication signals, are available on a DB25 connector (P1). Switchs configuration: CLK_SEL ENO_L LED2 LED1 CLASS/ECHOIN FIX IDL/GCI DRQ_AR PS1 PS2 Pulse 1 Pulse 2 OFF 2.048 MHz , ON 512 KHz ON (logic low) depending on the mode selected depending on the mode selected depending on the mode selected OFF Fix mode, ON Adaptative mode OFF IDL/SCP mode, ON GCI mode depending on the mode selected depending on the mode selected depending on the mode selected depending on the mode selected depending on the mode selected
Note: OFF applies a logic high, ON applies a logic low.
Motorola has designed a board (based on the HC11 and a FPGA) and software (on PC) which can be directly connected to the MC145576EVK board. This board (MC145576DRV) which works only in IDL/SCP mode, provides quick access to the internal registers and gated clocks.
V. Getting Started Jumpers configuration: JP8: jumper to short circuit the C13 capacitor. JP9: jumper to terminate the S/T loop transmit path with an 100 Ohms resistor. JP10: jumper to terminate the S/T loop receive path with an 100 Ohms resistor. Getting Started Configure the MC145576 according the mode choosen, then switch on the +5V power supply and reset the MC145576. The board is ready. VI. Reference Manuals
