SILICON GATE CMOS
PRELIMINARY
262,144 WORD x 16 BIT STATIC RAM
Description
The TC554161 FTUTRL is a 4,194,304 bit CMOS static random access memory organized as 262,144 words by 16 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 1OmNMHz (typ.) and a minimum cycle time of lOns. When CE is a logical high, the device is placed in a low
power standby mode in which the standby current is 1O~ (max.). The TC554161 FTUTRL has two control inputs. A chip enable
input (CE) allows for device selection and data retention control, while an output enable input (OE) provides fast memory access.
Byte access is supported by upper and lower byte controls. The TC554161 FTUTRL is suitable for use in microprocessor systems
where high speed, low power, and battery backup are required. The TC554161 FTUTRL is offered in a 54-pin thin small outline
plastic package (forward type, reverse type).
