SILICON GATE CMOS
TC55257CPI/CFI/CSPI/CFIl/CfRI-85L/10L
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 tem-
perature. The TC55257CPI 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. The TC55257CPI is suitable for use in microprocessor systems where high
speed, low power, and battery backup are required. The TC55257CPI is guaranteed over an operating temperature range of
-40 - 85°C so the TC55257CPI is suitable for use in wide operating temperature systems.
The TC55257CPI is offered in a standard dual-in-line 28-pin plastic package (0.6/0.3 inch width), a small outline plastic pack-
age, and a thin small outline plastic package (forward type, reverse type).
