TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS

1,048,576-WORD BY 16-BIT FULL CMOS STATIC RAM

DESCRIPTION

The TC55VCM416B, TC55VEM416B, TC55YCM416B and TC55YEM416B is a 16,777,216-bit static random

access memory (SRAM) organized as 1,048,576 words by 16 bits. Fabricated using Toshiba's CMOS Silicon gate

process technology, this device operates from a single 2.3 to 3.6 V/1.65 to 2.2 V power supply. Advanced circuit

technology provides both high speed and low power at an operating current of 2 mA/MHz and a minimum cycle

time of 55 ns. It is automatically placed in low-power mode at 0.7

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. Data byte control pin (

LB , UB ) 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. And, with a

guaranteed operating extreme temperature range of

−40° to 85°C, the TC55VCM416B, TC55VEM416B,

TC55YCM416B and TC55YEM416B can be used in environments exhibiting extreme temperature conditions. The

TC55VCM416BTGN/BSGN, TC55YCM416BTGN/BSGN is available in a plastic 48-pin thin-small-outline package

(TSOP). The TC55VEM416BXGN, TC55YEM416BXGN is available in a plastic 48-ball BGA.
