TC551001BPL/BFL/BFTL/BTRL-70L/85L
SILICON GATE CMOS
131,072 WORD x 8 BIT STATIC RAM
Description
The TC551001BPL is a 1,048,576 bits static random access memory organized as 131,072 words by 8 bits using CMOS technology,
and operated from a single 5V power supply. Advanced circuit techniques provide both high speed and low power features with an
operating current of 5mA/MHz (typ.) and a minimum cycle time of 70ns. When CE1 is a logical high, or CE2 is low, the device is
placed in a low power standby mode in which the standby current is 2µA typically. The TC551001BPL has three control inputs.
Chip Enable inputs (CE1, CE2) allow for device selection and data retention control, while an Output Enable input (OE) provides fast
memory access. The TC551001BPL is suitable for use in microprocessor application systems where high speed, low power, and
battery backup are required.
The TC551001BPL is offered in a standard dual-in-line 32-pin plastic package, a small outline plastic package, and a thin small
outline plastic package (forward, reverse type).
