描述 Description

The TC511632FL/FTL is a 512K bit high speed CMOS pseudo static RAM organized as 32,768 words by 16 bits. The

TC511632FL/FTL, utilizes a one transistor dynamic memory cell with CMOS peripheral circuitry to provide high capacity, high

speed and low power storage. The TC511632FL/FTL 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 TC511632FL/FTL 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 WE thus simplifying

the microprocessor interface.

The TC511632FL/FTL is available in a 40-pin small outline plastic flat package and a 44-pin outline (40 actual pins) plastic thin

small outline package (forward type).
