SILICON GATE CMOS
TC51V8512AF/ AFT/ A1R-12/15
PRELIMINARY
524,288 WORD x 8 BIT CMOS PSEUDO STATIC RAM
Description
The TC51V8512AF is a 4M bit high speed CMOS pseudo static RAM organized as 524,288 words by 8 bits. The TC51V8512AF
utilizes a one transistor dynamic memory cell with CMOS peripheral circuitry to provide high capacity, high s~ed and low power
storage. The TC51 V8512AF operates from a single 3.0V power supply. Refreshing is supported by a refresh (OEIRFSH) input which
enables two types of refreshing - auto refresh and self refresh. The TC51V8512AF features a static RAM-like interface with a write
cycle in which the input data is written into the memory cell at the rising edge of RIW thus simplifying the microprocessor interface.
The TC51V8512AF is available in a 32-pin small outline plastic flat package, and a thin small outline package (forward type,
reverse type).
