DESCRIPTION

The TC518128CPL/CSPL/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 TC518128CPL/CSPL/CFL/CFWL/CFTL meets the JEDEC CMOS SRAM pin-

compatibility standard and is available in molded 32-pin standard 0.6-inch and 0.3-inch dual-inline plastic

packages (DIP) and 0.45-inch and 0.525-inch small-outline plastic packages (SOP), and thin small-outline

plastic package (TSOP).
