Overview
http://onsemi.com
The ON Semiconductor serial SRAM family includes several
integrated memory devices including this 1 Mb serially accessed
Static Random Access Memory, internally organized as 128 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
TSSOP8 3x4.4

Interface (SPI) protocol. In SPI mode, a single data-in (SI) and
data-out (SO) line is used along with the clock (SCK) to access data
within the device. In DUAL mode, two multiplexed data-in/data-out

(SIO0-SIO1) lines are used and in QUAD mode, four multiplexed

data-in/data-out (SIO0-SIO3) lines are used with the clock to access
the memory. The devices can operate over a wide temperature range of
−40°C to +85°C and are available in a 8-lead TSSOP package. The
N01S830xA device has two different variations, a HOLD version that
