The N01S830HAT22I is a 1Mb ultra-low power serial SRAM in 8 pin TSSOP package. The serial SRAM family includes several integrated memory devices including this 1Mb serially accessed static random access memory, internally organized as 128K words by 8bits. The devices are designed and fabricated using 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 N01S830HA device has a HOLD version that allows communication to the device to be paused.
