25AA160BT-I/MS

Memory IC Overview

The Microchip Technology 25AA160BT-I/MS is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. 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 features a 32-byte page size. It is housed in an 8-lead MSOP package and supports an industrial temperature range 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 built-in power-on/off data protection

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging status. Confirm that the 'B' designation aligns with the required 32-byte page size. Ensure the 'I' suffix matches the intended industrial temperature operating range requirements.

Memory IC Selection Notes

Select this component when a low-voltage EEPROM interface is required alongside standard SPI compatibility. The 32-byte page buffer allows efficient sequential writes compared to older 16-byte variants. Verify that the MSOP package dimensions fit the target PCB layout constraints.

Memory IC Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs. The 'AA' prefix indicates support for 1.8 V operation, while the 'B' variant specifies a 32-byte page size. The 'MSOP' suffix denotes the 8-lead Mini Small Outline Package form factor used for space-constrained designs.

Memory IC Replacement Considerations

The 25AA160AT-I/MS serves as a direct functional substitute, differing primarily in its 16-byte page size configuration.
