DESCRIPTION

The TC518129CPL/CFL/CFWL/CFTL is a 1,048,578-bit CMOS pseudo static random access memory (PSRAM)

organized as 131,072 words by 8 bits. It feature a one-transistor dynamic memory cell using CMOS peripheral

circuitry to provide large capacity, high speed and low power. It uses a single 5 V ± 10 power supply. A

RFSH input selects either auto or self refresh operation. This device family also features SRAM-like write

functions whereby data is written to the memory cell rising edge of R/W signal, for easy interfacing to

microprocessors. The CE2 pin of the TC518128C family is replaced by the CS pin in this device family for

standby mode operation. The TC518129CPL/CFL/CFWL/CFTL is available in molded 32-pin standard 0.6-

inch dual-inline plastic packages (DIP) and 0.525-inch small-outline plastic packages (SOP), and thin small-

outline plastic package (TSOP).
