TC51832P-10

The TC51832P-10 belongs to TC51832 family which is a 256K bit high-speed CHOS Pseudo-Static RAM organized as 32,768 words by 8 bits. The TC51832P-10 utilizes one transistor dynamic memory cell array with CMOS peripheral circuitry to achieve large capacity, high speed accesses, and low power requirements, using a single 5V power supply. The OE/RFSH input allows two types of refresh operations: Auto Refresh and Self Refresh. The TC51832P-10 has a static RAMlike read/write functionality, which allows easy interfacing to a microprocessor. The TC51832P-10 is pin-compatable with the 256K bit static RAM. The TC51832P is offered in a standard 28 pin 0.6 inch and 0.3 inch width plastic DIP. The TC51832F is offered in a standard 28 pin 0.450 inch width small out-line plastic flat package.

The features of TC51832P-10 can be summarized as (1)organization: 256K bit(32,768 word*8 bit); (2)fast access time and low power dissipation; (3)self refresh current 1mA/100A; (4)single power supply: 5V±10%; (5)auto refresh uses an internal counter; (6)self refresh uses an internal timer; (7)all inputs and outputs: TTL compatible; (8)256 refresh cycle/4ms; (9)pin compatible: 256K SRAM TC55257; (10)logic compatible: SRAM R/W Pin, 28 pin standard plastic PKG, P/PL : 600 mil DIP, SP/SPL: 300 mil DIP, F/FL : 450 mil SOP.
