N64S830HA
64Kb Low Power Serial SRAMs
8K × 8 bit Organization
Overview
Features
The ON Semiconductor serial SRAM family
includes several integrated memory devices
including this 64K serially accessed Static
Random Access Memory, internally organized as
8K words by 8 bits. The devices are designed and
fabricated using ON Semiconductor’s advanced
CMOS 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
N64S830HA 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
range of -40^oC to +85^oC and can be available in
several standard package offerings.
