524,288-WORD BY 8-BIT FULL CMOS STATIC RAM
DESCRIPTION
TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
The TC55VCM208ASTN 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 and a minimum cycle time of 40 ns. It is automatically placed in low-power mode at 0.7
μ
A standby
current (at V
DD
=
3 V, Ta
=
25°C, typical) when chip enable (
CE1
) is asserted high or (CE2) is asserted low. There
are three control inputs.
CE1
and CE2 are 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. And, with a guaranteed operating extreme
temperature range of
40° to 85°C, the TC55VCM208ASTN can be used in environments exhibiting extreme
temperature conditions. The TC55VCM208ASTN is available in a plastic 40-pin thin-small outline package
(TSOP).
FEATURES
