Fonctionnalités et applications

Note: Not Recommended for new designs

The 25C320 (25XX320*)are 32 Kbit Serial Electrically Erasable PROMs. 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(bar)] input. Communication to the device can be paused via the hold pin [HOLD(bar)]. 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.
