DESCRIPTION
The P4C1041L is a 262,144 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-patible. The RAM operates from a single 5.0V ± 10% tolerance power supply.
Access times of 55 nanoseconds permit greatly enhanced system operating speeds. CMOS is utilized to reduce power consumption to a low level.
The P4C1041L device provides asynchronous operation with matching access and cycle times. Memory locations are specified on address pins A0 to A17. Reading is acplished 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.
The P4C1041L es in a 44-Pin 400 mil TSOP II package.
