TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
1,048,576-WORD BY 16-BIT FULL CMOS STATIC RAM
DESCRIPTION
The TC55VEM416AXBN 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 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 0.9

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
TC55VEM416AXBN can be used in environments exhibiting extreme temperature conditions. The
TC55VEM416AXBN is available in a plastic 48-ball BGA.
FEATURES
