25AA160/P

Memory IC Overview

The Microchip Technology 25AA160/P is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It features an SPI-compatible serial bus interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an industrial temperature range of -40°C to +85°C. It utilizes an 8-pin PDIP package and includes hardware write protection, self-timed erase/write cycles, and high reliability with over 200 years of data retention.

Memory IC Feature Summary

• Supports low-power CMOS technology with typical standby current of 500 nA
• Includes built-in write protection via power on/off circuitry and dedicated WP pin
• Features block write protection allowing selection of none, 1/4, 1/2, or all array segments
• Provides sequential read capability with automatic address pointer increment

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter storage
• Calibration data retention
• General-purpose nonvolatile memory applications

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Confirm RoHS compliance status through official documentation. Check for Not Recommended for New Designs (NRND) status before finalizing procurement decisions. Ensure compatibility with existing SPI bus protocols and voltage levels.

Memory IC Selection Notes

Select this component for applications requiring 16 Kbit of nonvolatile storage with SPI interface. Consider the 1 MHz maximum clock speed and 1.8 V to 5.5 V operating voltage range. Evaluate the need for hardware write protection features. Compare against newer alternatives if long-term availability is a primary concern.

Memory IC Part Context

This part belongs to the 25XX160 family of 16 Kbit Serial EEPROMs from Microchip Technology. It shares functional similarities with the 25LC160 and 25C160 variants, differing primarily in operating voltage ranges and temperature specifications. The PDIP package variant is designated by the '/P' suffix.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers include 25AA160A/B and 25LC160A/B as recommended replacements.
