TC55257BPI/BFI/BSPI/BFTI/BTRI-IOL
SILICON GATE CMOS
32,768 WORD x 8 BIT STATIC RAM
Description
The TC55257BPI is a 262,144 bit CMOS static random access memory organized as 32,768 words by 8 bits and operated from a single 5V power supply. Advanced circuit techniques provide both high speed and low power features with an operating current of
5mAlMHz fu:p.) and a minimum cycle time of 100ns. When CE is a logical high, the device is placed in a low power standby mode in which the standby current is 2J..tA at room tem-
perature. The TC55257BPI has two control inputs. Chip enable (CE) allows for device selection and data retention control, while an output enable input (OE) provides fast memory access.
