P3C1021

P3C1021 HIGH SPEED 64K x 16 (1 MEG) STATIC CMOS RAM FEATURES High Speed (Equal Access and Cycle Times) — 10/12/15/20 ns (Commercial) — 12/15/20 ns (Industrial) Low Power — 325 mW (max.) Single 3.3V ± 0.3V Power Supply Easy Memory Expansion Using CE and OE Inputs DESCRIPTION The P3C1021 is a 65,536 words by 16 bits high-speed CMOS static RAM. The CMOS memory requires no clocks or refreshing, and has equal access and cycle times. Inputs are fully TTL-compatible. The RAM operates from a single 3.3V ± 0.3V tolerance power supply. Access times as fast as 10 nanoseconds permit greatly enhanced system operating speeds. CMOS is utilized to reduce power consumption to a low level. The P3C1021 is a member of a family of PACE RAM™ products offering fast access times. FUNCTIONAL BLOCK DIAGRAM Fully TTL Compatible Inputs and Outputs Advanced CMOS Technology Fast tOE Automatic Power Down when deselected Packages —44-Pin SOJ, TSOP II The P3C1021 device provides asynchronous operation with matching access and cycle times. Memory locations are specified on address pins A0 to A15. Reading is accomplished by device selection (CE and output enabling (OE) while write enable (WE) remains HIGH. By presenting the address under these conditions, the data in the addressed memory location is presented on the data input/output pins. The input/output pins stay in the HIGH Z state when either CE or OE is HIGH or WE is LOW. Package options for the P3C1021 include 44-pin SOJ and TSOP packages. PIN CONFIGU...
