TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
Lead-Free
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 μA standby current (at VDD = 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. 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.
