SRAM Chip Sync Single 1.8V 256K-Bit 32K x 8 32ns 8-Pin TSSOP T/R

The 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 ON Semiconductor’s 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 N25S818HA 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. Power Supply Range: 1.7 to 1.95 V Very Low Standby Current: Typical Isb as low as 200 nA Very Low Operating Current: As low as 3 mA Simple Memory Control: Single chip select (CS) Serial input (SI) and serial output (SO) Flexible Operating Modes: Word read and write Page mode (32 word page) Burst mode (full array) Organization: 32 k x 8 bit Self Timed Write Cycles Built-in Write Protection (CS High) HOLD Pin for Pausing Communication High Reliability: Unlimited write cycles Green SOIC and TSSOP These Devices are Pb-Free, Halogen Free/BFR Free and are RoHS Compliant
