The devices are designed and fabricated using AMI’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 N256S08xxHDA 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 -40oC to +85oC and can be available in several standard package offerings. Features Power Supply Options 1.8V to 3.6V Very low standby current As low as 200nA Very low operating current As low as 500uA 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 32K x 8 bit Self timed write cycles Built-in write protection (CS high)...
