  • Overview
    23K256-I/SN Product overview

    The 23K256-I/SN is a 256K SPI bus low-power Serial SRAM Device. The memory is accessed via a simple serial peripheral interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input. Communication to the device can be paused via the hold pin (hold). While the device is paused, transitions on its inputs will be ignored, with the exception of chip select, allowing the host to service higher priority interrupts.

    N25S830HAT22I Product overview

    The ON Semiconductor serial SRAM family includes several integrated memory devices including this 256 kb serially accessed Static Random Access Memory, internally organized as 32 k words by 8 bits. 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) serial bus. A single data in and data out line is used along with a clock to access data within the devices. The N25S830HA 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. Features ---
