25AA160B-I/P

Memory IC Overview

The Microchip Technology 25AA160B-I/P is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus for data access, supporting a maximum clock frequency of 10 MHz. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperature ranges from -40 °C to +85 °C. It incorporates a 32-byte page size and is housed in an 8-lead PDIP package.

Memory IC Feature Summary

• Supports block write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Includes built-in power-on/off data protection circuitry with a write enable latch mechanism.
• Features a hold pin capability to pause serial communication without resetting the sequence.

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Memory IC Procurement Notes

Verify the specific ordering suffix 'I/P' confirms the Industrial temperature grade (-40°C to +85°C) and the 8-lead PDIP package type. Ensure the 'B' designation matches the required 32-byte page size configuration. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Memory IC Selection Notes

Select this component when a low-voltage operation down to 1.8 V is required alongside standard SPI interface compatibility. The 32-byte page size offers higher throughput compared to 16-byte variants. Verify that the 8-lead PDIP package aligns with the target printed circuit board layout and assembly requirements.

Memory IC Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'B' variant specifically denotes a 32-byte page size, distinguishing it from the 'A' version which uses a 16-byte page. The 'I' suffix indicates the industrial temperature rating, while 'P' designates the plastic dual in-line package format.

Memory IC Replacement Considerations

The 25AA160A-I/P serves as a functional substitute if a 16-byte page size is acceptable. The 25LC160B-I/P provides equivalent specifications but requires a minimum operating voltage of 2.5 V instead of 1.8 V.
