N25S818HA
256 kb Low Power Serial
SRAMs
32 k x 8 Bit Organization
Introduction
The ON Semiconductor serial SRAM family includes several
integrated memory devices including this 256 kb serially accessed
Static Random Access Memory, internally organized as 32 k 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 N25S818HA
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 ° C to +85 ° C
and can be available in several standard package offerings.
