TC55V040AFT-55,-70
TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
524,288-WORD BY 8-BIT FULL CMOS STATIC RAM
DESCRIPTION
The TC55V040AFT 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 55 ns. It is automatically placed in low-power mode at 0.5 µA standby
current (at VDD = 3 V, Ta = 25°C, maximum) 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 TC55V040AFT can be used in environments exhibiting extreme
temperature conditions. The TC55V040AFT is available in normal and reverse pinout plastic 40-pin
thin-small-outline package (TSOP).
