TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
524,288-WORD BY 8-BIT STATIC RAM
DESCRIPTION
The TC55VEM208ASTN is a 4,194,304-bit static random access memory (SRAM) organized as 524,288 words by
8 bits. Fabricated using Toshiba's CMOS Silicon gate process technology, this device operates from a single 2.3 to
3.6 V power supply. Advanced circuit technology provides both high speed and low power at an operating current of
3 mA/MHz (typ) and a minimum cycle time of 40 ns. It is automatically placed in low-power mode at 0.7 µA standby
current (typ) when chip enable ( CE ) is asserted high. There are two control inputs. CE is used to select the device
and for data retention control, and output enable ( OE ) provides fast memory access. This device is well suited to
various microprocessor system applications where high speed, low power and battery backup are required. The
TC55VEM208ASTN is available in a plastic 32-pin thin-small-outline package (TSOP).
