Description
The TC518512PI is a 4M bit high speed CMOS pseudo static RAMorganized as 524,288 words by 8 bits. The TC518512PI utilizes
a one transistor dynamic memory cell with CMOS peripheral circuitry to provide high capacityJ:!!,9h speed and low power storage. The
TC518512PI operates from a single 5V power supply. Refreshing is supported by a refresh (OEIRFSH) input which enables two
types of refreshing - auto refresh and self refresh. The TC518512PI 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 RIW thus simplifying the microprocessor interface. The
TC518512PI is guaranteed over an operating temperature range of -40 - 85°C.
The TC518512PI is available in a 32-pin, 0.6 inch width plastic DIP and a small outline plastic flat package.
