25LC160DT-E/SN16KVAO

Overview

The Microchip Technology 25LC160DT-E/SN16KVAO is a 16 Kbit Serial Electrically Erasable PROM featuring SPI-compatible bus access. It utilizes a 32-byte page architecture and supports clock frequencies up to 10 MHz at 4.5V-5.5V, 5 MHz at 2.5V-4.5V, and 3 MHz at 1.8V-2.5V. The device operates within a supply voltage range of 1.8V to 5.5V and an extended temperature range of -40°C to +125°C. It is housed in an 8-lead SOIC package.

Feature Summary

• Supports serial communication via a standard SPI-compatible interface with separate data input and output lines.
• Includes hardware write protection mechanisms such as block protection and power-on/off data protection circuitry.
• Features a hold pin that allows the host to pause serial communication without resetting the sequence.

Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control applications needing reliable memory in high-temperature environments
• Automotive electronics utilizing automotive-grade components

Procurement Notes

Verify the specific suffix 'SN16KVAO' against official Microchip documentation to confirm packaging details and environmental compliance status. Ensure the selected component matches the required industrial or automotive temperature grade specifications for your design constraints.

Selection Notes

Select this component when an extended operating temperature range up to 125°C is required alongside low-power consumption. The 32-byte page size offers efficient writing capabilities compared to smaller page alternatives. Verify compatibility with the system's SPI clock speed requirements across the full voltage range.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. It shares core architectural features with other variants in the series but is distinguished by its specific temperature rating and packaging configuration suitable for demanding operational environments.

Replacement Considerations

Direct replacements include other 25LC160D variants with compatible packages and temperature ratings. Verify pinout compatibility and electrical characteristics before substituting with similar SPI EEPROM devices from different manufacturers.

FAQ

What is the maximum clock frequency supported by this device?

The device supports a maximum clock frequency of 10 MHz when the supply voltage is between 4.5V and 5.5V.

How does the HOLD pin function during operation?

The HOLD pin allows the user to pause serial communication without resetting the sequence. Transitions on SI, SCK, and SO are ignored while the device is paused.
