SILICON GATE CMOS
131,072 WORD x 8 BIT CMOS PSEUDO STATIC RAM
Description
The TC518129B-V is a 1M bit high speed CMOS pseudo static RAM organized as 131,072 words by 8 bits. The TC518129B-V
utilizes a one transistor dynamic memory cell with CMOS peripheral circuitry to provide high capacity, high speed and low power
storage. The TC518129B-V operates from a single power supply of 2.7 - 5.5V. Refreshing is supported by a refresh (RFSf-i input
which enables two types of refreshing - auto refresh and self refresh. The TC518129B-V 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.
A CS standby mode interface is incorporated in the TC518129B-V family, with the CE2 pin in the TC518128B-V family changed
to a CS pin. The TC518129B-V is available in a 32-pin, 0.6 inch width plastic DIP, a small outline plastic flat package, and a 32-pin thin
small outline plastic package (forward type).
