25AA160-I/P

Memory IC Overview

The Microchip Technology 25AA160-I/P is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It operates within a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 1 MHz. The device utilizes an SPI-compatible serial bus with SCK, SI, SO, CS, HOLD, and WP pins. It is housed in an 8-pin PDIP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology with typical standby current of 500 nA
• Built-in write protection including power on/off data protection and block write protection
• High reliability with 1 million cycle endurance and over 200 years data retention
• Serial communication pause capability via the HOLD pin

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device status as Not Recommended for New Designs (NRND) and evaluate alternative components such as the 25AA160A/B series for long-term project viability. Ensure compatibility with existing SPI interface timing requirements.

Memory IC Selection Notes

Select this component when a low-cost, industry-standard SPI EEPROM is required for non-volatile data storage. The 1.8V minimum operating voltage allows integration with lower voltage logic systems. Consider the 8-pin PDIP package for through-hole prototyping or applications requiring manual insertion. Verify that the 1 MHz maximum clock speed meets the system's throughput needs.

Memory IC Part Context

This part belongs to the 25XX160 family of 16 Kbit Serial EEPROMs from Microchip Technology. It shares architectural similarities with the 25LC160 and 25C160 variants, differing primarily in operating voltage ranges and temperature specifications. The device is designed for direct interfacing with microcontrollers possessing SPI ports.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 25AA160A/I-P and 25AA160B/I-P.
