Overview
The ON Semiconductor N01S830HAT22I is a 1 Mb serially accessed Static Random Access Memory (SRAM) device. It is internally organized as 128 K words by 8 bits and is designed using ON Semiconductor’s advanced CMOS technology to provide high-speed performance and low power consumption. The device operates with a single chip select (CS) input and uses a simple Serial Peripheral Interface (SPI) protocol, supporting single-bit, DUAL-bit, and QUAD-bit SPI-like access modes. It is available in an 8-lead TSSOP package and can operate over a wide temperature range of −40°C to +85°C.
