MARKING
DIAGRAMS
The ON Semiconductor serial SRAM family includes several
integrated memory devices including this 64 k serially accessed Static
Random Access Memory, internally organized as 8 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 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°C
to +85°C and can be available in several
standard package offerings.
