25LC160AT-E/MS

Overview

The Microchip Technology 25LC160AT-E/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. The device operates within a supply voltage range of 2.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. It includes a 16-byte page write buffer, self-timed erase/write cycles, and hardware write protection capabilities.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes built-in power-on/off data protection and write enable latch
• Features programmable block write protection for array segments
• Provides hold functionality to pause serial sequences without resetting

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage in embedded systems

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the 'E' designation aligns with the required automotive temperature grade (-40°C to +125°C) if applicable, as datasheet tables list 'I' for industrial and 'E' for automotive ranges. Ensure the 'A' version matches the 16-byte page size requirement rather than the 32-byte 'B' version.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required. Choose the 'E' suffix variant if operation beyond +85°C up to +125°C is necessary. Verify that the 16-byte page size suits the application's write granularity needs compared to the 32-byte option available in the 'B' series.

Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs from Microchip Technology. The family shares common architecture but varies by voltage range (AA vs LC), page size (A vs B), and temperature grade (I vs E). The MSOP package offers a compact surface-mount solution suitable for space-constrained designs.

Replacement Considerations

Public confirmed substitutes include other variants within the 25LC160A/B family such as 25LC160A-E/MS or 25LC160B-E/MS, provided pinout and electrical characteristics match the specific design requirements.
