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.
