Overview

Product Highlight

  • Memory Density: 32 kb
  • Memory Organization: 4 K x 8
  • Supply Voltage-Nom: 1.8 to 5.5 V
  • Clock Frequency-Max: 10 MHz
  • Write Cycle Time-Max (tWC): 5 ms

The 25AA320A (25XX320A*) series of 32 kbit Serial Electrically Erasable PROM 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. The 25XX320A is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, TSSOP and 2x3 TDFN.
