524,288-WORD BY 16-BIT/1,048,576-WORD BY 8-BIT FULL CMOS STATIC RAM
DESCRIPTION
words by 16 bits/1,048,576 words by 8 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 40 ns. It is automatically placed in
low-power mode at 0.7 A standby current (at V
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 TC55VBM316AFTN/ASTN can be used in environments exhibiting extreme
temperature conditions. The TC55VBM316AFTN/ASTN is available in a plastic 48-pin thin-small-outline package
(TSOP).
