1 Mb Ultra-Low Power
Serial SRAM
Standard SPI Interface and Multiplex
DUAL and QUAD Interface
Overview
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
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 (+125°C for E−Temp) and are available in a 8-lead
TSSOP package. The N01S830xA device has two different variations,
a HOLD version that allows communication to the device to be paused
and a battery back-up (BBU) version to be used with a battery to retain
data when power is lost.
