TC55257CFTI-85 Overview
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 5mNMHz i!YP.) and a minimum cycle time of 85ns.
Key Features
- with an operating current of 5mNMHz i!YP.) 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 21lA 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) provides fast memory access
- The TC55257CPI is suitable for use in microprocessor systems where high speed, low power, and battery backup are required
