25LC160CT-E/SN

Overview

The Microchip Technology 25LC160CT-E/SN is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with SCK, SI, SO, CS, and HOLD pins. The device supports a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. It operates within a supply voltage range of 1.8V to 5.5V and includes a 16-byte page size. The component is housed in an 8-lead SOIC package and supports an industrial temperature range of -40°C to +85°C.

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 power-on/off data protection circuitry and self-timed erase/write cycles
• Provides hold functionality to pause serial communication without resetting the sequence

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage
• Device identification and tracking

Procurement Notes

Verify the specific suffix 'E' indicates automotive grade reliability (-40°C to +125°C) against the datasheet's general listing for 25LC160C which specifies Industrial (I) or Automotive (E) ranges. Confirm the 'T' suffix denotes tape and reel packaging if required by assembly equipment. Ensure the 'SN' package matches the target PCB footprint. Cross-reference the exact part number with the manufacturer's current availability status as product lifecycles may change.

Selection Notes

Select this component when an SPI interface is preferred over I2C for memory applications requiring 16 Kbit capacity. The 25LC160C variant offers a 16-byte page size, distinct from the 32-byte page of the 25LC160D. Consider the operating voltage range and temperature requirements; the 'E' suffix typically denotes extended automotive temperature grades. Verify that the host microcontroller can support the required SPI mode and timing constraints.

Part Context

This device belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. The family shares common architectural features but differs in page sizes and voltage ranges. The 25LC160C specifically targets applications needing low-power operation with standard SPI compatibility. It serves as a non-volatile memory solution for embedded systems requiring frequent data updates.

Replacement Considerations

The 25LC160DT-E/MS is a direct functional substitute offering identical electrical characteristics but packaged in TDFN format instead of SOIC. Other variants like 25LC160C-I/SN provide the same specifications within the industrial temperature range rather than the extended automotive range indicated by the 'E' suffix.
