25LC160DT-I/MS

Overview

The Microchip Technology 25LC160DT-I/MS is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC ≥ 4.5V and 5 MHz at 2.5V ≤ VCC < 4.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It employs a 32-byte page size for write operations and is housed in an 8-lead MSOP package.

Feature Summary

• Supports high-speed SPI communication with sequential read capabilities and hold functionality for interrupt servicing.
• Includes built-in hardware write protection via the WP pin and software block protection through the STATUS register.
• Features self-timed erase and write cycles with power-on/off data protection circuitry.

Applications

• Microcontroller system configuration storage
• Calibration parameter persistence
• Log data buffering

Procurement Notes

Verify the specific suffix 'DT' against the official datasheet, as standard documentation typically lists 'D' for 32-byte page devices. Confirm that the 'I' designation matches the required industrial temperature range (-40°C to +85°C). Ensure the MSOP package dimensions align with the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required for non-volatile data storage. The 32-byte page size offers efficient bulk writing compared to smaller page variants. Ensure the system voltage remains within the 2.5V to 5.5V operating range to maintain specified performance levels and endurance characteristics.

Part Context

This part belongs to the 25LC160C/D series of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'D' variant specifically denotes a 32-byte page size, distinguishing it from the 'C' variant which uses a 16-byte page. The series is designed for low-power applications requiring reliable data retention and high endurance.

Replacement Considerations

The 25LC160D-I/MS is a direct functional equivalent with identical specifications. Other compatible parts include the 25LC160B series, though page sizes and voltage ranges should be verified against the specific application requirements.
