256Kb Low Power Serial SRAMs

32K × 8 bit Organization

Overview

Features

The AMI Semiconductor serial SRAM family

includes several integrated memory devices

including this 256Kb serially accessed Static

Random Access Memory, internally organized as

32K words by 8 bits. The devices are designed and

fabricated using AMI’s advanced CMOS

• Power Supply Options

1.8V to 3.6V

• Very low standby current

As low as 200nA

• Very low operating current

As low as 500uA

technology to provide both high-speed

performance and low power. The devices operate

with a single chip select (CS) input and use a

simple Serial Peripheral Interface (SPI) serial bus.

A single data in and data out line is used along with

a clock to access data within the devices. The

N256S08xxHDA devices include a HOLD pin that

allows communication to the device to be paused.

While paused, input transitions will be ignored.

The devices can operate over a wide temperature

• Simple memory control

Single chip select (CS)

Serial input (SI) and serial output (SO)

• Flexible operating modes

Word read and write

Page mode (32 word page)

Burst mode (full array)

• Organization

32K x 8 bit

range of -40 C to +85 C and can be available in

• Self timed write cycles

several standard package offerings.

• Built-in write protection (CS high)

• HOLD pin for pausing communication

• High reliability

Unlimited write cycles

• RoHS Compliant Packages
