25AA160D-E/P

Memory IC Overview

The Microchip Technology 25AA160D-E/P is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization and 32-byte page size. It operates via an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC ≥ 4.5V. The device supports a supply voltage range of 1.8V to 5.5V and functions within an industrial temperature range of -40°C to +85°C. It is housed in an 8-lead PDIP package.

Memory IC Feature Summary

• Supports block write protection for none, 1/4, 1/2, or all array segments
• Includes built-in power-on/off data protection circuitry
• Features a hold pin to pause serial communication without resetting the sequence

Memory IC Applications

• Microcontroller system data storage
• Industrial control applications
• Embedded systems requiring non-volatile memory

Memory IC Procurement Notes

Verify the specific ordering suffix 'E' indicates automotive temperature grade (-40°C to +125°C) against official documentation, as datasheet tables list 'I' (Industrial) and 'E' (Automotive) ranges separately. Confirm package type matches the 'P' designation for PDIP-8. Ensure compliance requirements such as RoHS status are validated through current manufacturer declarations before procurement.

Memory IC Selection Notes

Select this component when low-power CMOS technology and high reliability are required for embedded memory solutions. The device offers over 1 million erase/write cycles and data retention exceeding 200 years. Consider the 32-byte page size for efficient sequential writes. Verify that the operating voltage range aligns with the system's power supply constraints.

Memory IC Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. These devices are designed for direct interface with SPI ports of popular microcontroller families. The family includes variants with different voltage ranges and page sizes, providing flexibility for various application needs while maintaining consistent pinouts and instruction sets.

Memory IC Replacement Considerations

Check for 25LC160D-E/P if a 2.5V minimum supply voltage is acceptable. Verify compatibility with 25AA160D-I/P if only industrial temperature range is needed.
