TC554161AFT-70,-85,-10,-70L,-85L,-10L

TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS

262,144-WORD BY 16-BIT STATIC RAM

DESCRIPTION

The TC554161AFT is a 4,194,304-bit static random access memory (SRAM) organized as 262,144 words by 16bits.

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 10

mA/MHz (typ) and a minimum cycle time of 70 ns. It is automatically placed in low-power mode at 2

standby

current (typ) when chip enable (

) is asserted high. There are two control inputs.

is used to select the device

and for data retention control, and output enable (

) provides fast memory access. Data byte control pin (

) provides lower and upper byte access. This device is well suited to various microprocessor system applications

where high speed, low power and battery backup are required. The TC554161AFT is available in a plastic 54-pin

thin-small-outline package (TSOP).

FEATURES

Low-power dissipation

Operating: 55 mW/MHz (typical)

Single power supply voltage of 5 V
