25LC160AT-I/ST

Overview

The Microchip Technology 25LC160AT-I/ST is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 10 MHz via an SPI-compatible serial bus. The device features a 16-byte page size, self-timed erase/write cycles with a maximum duration of 5 ms, and industrial temperature ratings from -40°C to +85°C. It is housed in an 8-lead TSSOP package.

Feature Summary

• Supports high-speed SPI communication up to 10 MHz
• Includes built-in hardware write protection mechanisms
• Features power-on/off data protection circuitry
• Provides programmable block write protection

Applications

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

Procurement Notes

Verify the specific suffix 'A' indicates the 16-byte page size variant. Confirm the 'I' designation matches the required industrial temperature range. Ensure the 'ST' suffix corresponds to the TSSOP package type for your PCB layout requirements.

Selection Notes

Select this component when a low-pin-count non-volatile memory solution is needed for small data sets. It is suitable for applications requiring frequent updates or secure configuration storage where hardware write protection is necessary.

Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs. It shares functional similarities with the 25AA160A/B series but differs in minimum operating voltage specifications. The 'A' version specifically denotes a 16-byte page buffer capacity.

Replacement Considerations

Public confirmed substitute part numbers: 25LC160B-I/ST, 25LC160T-I/SN.
