Ordering number : EN4163A Asynchronous Silicon Gate CMOS LSI LC36256AL, AML-70/85/10/12 256 K (32768 words × 8 bits) SRAM Overview The LC36256AL, AML are fully asynchronous silicon gate CMOS static RAMs with an 32768 words × 8 bits configuration. This series have CE chip enable pin for device select/nonselect control and an OE output enable pin for output control, and features high speed as well as low power dissipation. For these reasons, the series is especially suited for use in systems requiring high speed, low power, and battery backup, and it is easy to expand memory capacity.

(2) An external antiphase signal must not be applied when DOUT is in the output state. (3) tWP is the time interval that CE and WE are low-level and is defined as the interval from the falling of WE to the rising of CE or WE whichever is earlier. (4) tCW is the time interval that CE and WE are low-level and is defined as the time from the falling of CE to the rising of CE or WE whichever is earlier. (5) DOUT goes to the high-impedance state when either OE is high-level, CE is high-level, or WE is low-level. (6) When OE is high-level during the write cycle, DOUT goes to the high-impedance state.
