PRELIMINARY
32,768 WORD x 8 BIT STATIC RAM
Description
The TC55257CPI 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 iliP.) and a minimum cycle time of 85ns.
When CE is a logical high, the device is placed in a low power standby mode in which the standby current is 2~ at room temperature. The TC55257CPI has two control inputs. Chip enable (CE) allows for device selection and data retention control, while an output enable input (OE)...
