25AA320属于集成电路（IC）的存储器。由美国微芯科技公司制造生产的25AA320存储器存储器是集成电路上用作数据存储设备的半导体器件。这些器件分为非易失性或易失性两种，格式包括 CBRAM、DRAM、EEPROM、EERAM、EPROM、闪存、FRAM、NVSRAM、PCM (PRAM)、PSRAM、RAM 和 SRAM。这些器件的存储容量为 64 b 至 6 Tb 不等，接口有 I2C、MMC、并行、eMMC、串行、单线、SPI、UFS、Xccela 总线和 1-线。

Description:

The Microchip Technology Inc. 25AA320/25LC320/25C320 (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) 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.
