The 25C160/SN is an SPI serial E2PROM manufactured by Microchip Technology Inc. This device is a 16K nonvolatile memory organized as 2K x 8. It has an SPI-compatible serial input/output with simplified read and write operations and is available in space saving 8-SOIC, 8-PDIP, 8-TDFN, 8-TSSOP, 16-SOIC, 16-TSSOP and 16-TDFN packages. It also has a write protection mechanism, a self-timed write cycle, no-write cycle, and global write protect feature. The 25C160/SN has a capacitance of 10pF and an access time of 120ms. This device is ideal for applications that require data to be reliably stored, such as memory cards, security systems and portable devices.
