N01S830BAT22I

The N01S830BAT22I is a 1Mb ultra-low power serial SRAM in 8 pin TSSOP package. The serial SRAM family includes several integrated memory devices including this 1 Mb 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 battery back-up version to be used with a battery to retain data when power is lost.
