TC518512PL/FL/FIL/TRL-70(DR) /80 (DR) /10 (DR)
SILICON GATE CMOS
524,288 WORD x 8 BIT CMOS PSEUDO STATIC RAM
Description
The TC518512PL is a 4M bit high speed CMOS pseudo static RAM organized as 524,288 words by 8 bits. The TC518512PL utilizes
a one transistor dynamic memory cell with CMOS peripheral circuitry to provide high capacity, .!J!gh speed and low power storage. The
TC518512PL operates from a single 5V power supply. Refreshing is supported by a refresh (OEIRFSH) input which enables two
types of refreshing - auto refresh and self refresh. The TC518512PL 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 RNV thus simplifying the microprocessor interface.
The TC518512PL is available in a 32-pin, 0.6 inch width plastic DIP, a small outline plastic flat package, and a thin small outline
package (forward type, reverse type).
