25AA160BT-I/SN

Memory IC Overview

The Microchip Technology 25AA160BT-I/SN is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It utilizes an SPI-compatible serial bus for communication, supporting a maximum clock frequency of 10 MHz. The device features a 32-byte page size and operates within a supply voltage range of 1.8 V to 5.5 V. It is housed in an 8-lead MSOP package and supports industrial temperature ranges from -40 °C to +85 °C.

Memory IC Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write protection via WP pin and software block protection
• Features self-timed erase and write cycles with internal write enable latch
• Provides data retention exceeding 200 years and endurance of 1,000,000 cycles

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'T' against official Microchip documentation to confirm tape-and-reel packaging status. Ensure the 'I' designation matches required industrial temperature specifications. Confirm RoHS compliance and lead-free status through manufacturer datasheets or component markings before procurement.

Memory IC Selection Notes

Select this component when low-voltage operation down to 1.8 V is required, distinguishing it from the 2.5 V minimum 25LC160 series. Choose the 'B' version for 32-byte page writes instead of 16-byte pages. Verify that the MSOP package fits the target PCB footprint and that the industrial temperature rating meets environmental constraints.

Memory IC Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs. It shares architectural similarities with the 25LC160 series but differs in operating voltage requirements. The 'SN' suffix indicates an SOIC package, while 'MS' denotes MSOP; verify if 'SN' in the model string implies a specific variant or potential typo relative to the requested MSOP package.

Memory IC Replacement Considerations

The 25AA160AT-I/MS is a direct replacement offering identical electrical characteristics and functionality in the same MSOP package format.
