R1RW0416DI Series
Wide Temperature Range Version 4M High Speed SRAM (256-kword x 16-bit)
REJ03C0109-0100Z Rev. 1.00 Mar.12.2004
Description
The R1RW0416DI is a 4-Mbit high speed static RAM organized 256-kword x 16-bit. It has realized high speed access time by employing CMOS process (6-transistor memory cell) and high speed circuit designing technology. It is most appropriate for the application which requires high speed, high density memory and wide bit width configuration, such as cache and buffer memory in system. The R1RW0416DI is packaged in 400-mil 44-pin SOJ and 400-mil 44-pin plastic TSOPII for high density surface mounting.
Features
* Single 3.3 V supply: 3.3 V 0.3 V * Access time: 12 ns (max) * Completely static memory No clock or timing strobe required * Equal access and cycle times * Directly TTL compatible All inputs and outputs * Operating current: 130 mA (max) * TTL standby current: 40 mA (max) * CMOS standby current: 5 mA (max) * Center VCC and VSS type pin out * Temperature range: -40 to +85C

Notes: 1. Transition is measured 200 mV from steady voltage with output load (B). This parameter is sampled and not 100% tested. 2. If the CS# or LB# or UB# low transition occurs simultaneously with the WE# low transition or after the WE# transition, output remains a high impedance state. 3. WE# and/or CS# must be high during address transition time. 4. If CS#, OE#, LB# and UB# are low during this period, I/O pins are in the output state. Then the data input signals of opposite phase to the outputs must not be applied to them. 5. tAS is measured from the latest address transition to the latest of CS#, WE#, LB# or UB# going low. 6. tWR is measured from the earliest of CS#, WE#, LB# or UB# going high to the first address transition. 7. A write occurs during the overlap of a low CS#, a low WE# and a low LB# or a low UB# (tWP). A write begins at the latest transition among CS# going low, WE# going low and LB# going low or UB# going low. A write ends at the earliest transition among CS# going high, WE# going high and LB# going high or UB# going high. 8. tCW is measured from the later of CS# going low to the end of write.
