TENTATIVE
524,288-WORD BY 8-BIT STATIC RAM
DESCRIPTION
TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
The TC55NEM208AFPN/AFTN 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 5V
±
10% 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 55 ns. It is automatically placed in low-power mode at 1
μ
A
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.
And, with a guaranteed operating range of
40° to 85°C, the TC55NEM208AFPN/AFTN can be used in
environments exhibiting extreme temperature conditions. The TC55NEM208AFPN/AFTN is available in a
standard plastic 32-pin small-outline package (SOP) and normal and reverse pinout plastic 32-pin
thin-small-outline package (TSOP).
