Description

The TC518129A is a 1M bit high speed CMOS pseudo static RAM organized as 131,072 words by 8 bits. The TC518129A utilizes

a one transistor dynamic memory cell with CMOS peripheral circuitry to provide high capacity, high speed and low power storage. The

TC518129A operates from a single 5V power supply. Refreshing is supported by a refresh (RFSH) input which enables two types of

refreshing-auto refresh and self refresh. The TC518129A 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 R/WW thus simplifying the microprocessor interface.

A CS standby mode interface is incorporated in the TC518129A family, with the CE2 pin in the TC518128A family changed to a

CS pin. The TC518129A is available in a 32-pin, 0.6 inch and 0.3 inch width plastic DIP, a small outline plastic flat package, and a

32-pin thin small outline plastic package (forward type).
