Overview
The ON Semiconductor N25S830HAS22IT is a 256 kb serially accessed Static Random Access Memory (SRAM) device. It is internally organized as 32 k words by 8 bits and is designed using 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) serial bus. It features a single data in and data out line along with a clock to access data within the device. The N25S830HAS22IT also includes a HOLD pin that allows communication to the device to be paused, ignoring input transitions while paused. The device can operate over a wide temperature range of -40°C to +85°C and is available in several standard package offerings.
