25LC160DT-E/MS

Overview

The Microchip Technology 25LC160DT-E/MS is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes a 2048 x 8-bit organization with a 32-byte page size for the 'D' version devices. The component operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 10 MHz at higher voltages, scaling down to 3 MHz at lower supply levels. It is housed in an 8-lead MSOP package and designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports serial communication via a standard SPI bus with separate data input and output lines.
• Includes hardware write protection mechanisms such as block protection and power-on data protection circuitry.
• Features a hold pin that allows suspension of serial communication without resetting the sequence.

Applications

• Data storage in microcontroller systems requiring non-volatile memory
• Configuration parameter retention in embedded applications
• Industrial control systems operating within specified temperature ranges

Procurement Notes

Verify the specific suffix requirements against current official documentation before procurement. Confirm that the device meets all necessary environmental and electrical specifications for the intended application environment. Ensure compatibility with existing system interfaces and voltage levels.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required. Consider the 32-byte page size for efficient data writing operations. Verify that the operating temperature range and voltage supply align with system constraints. Evaluate the need for hardware write protection features provided by the WP pin and status register bits.

Part Context

This part belongs to the 25XX160C/D family of Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different page sizes and voltage ranges, such as the 25AA160 series which supports lower voltage operation. The 'D' designation indicates a 32-byte page size, while 'E' denotes extended temperature capabilities.

Replacement Considerations

Direct replacements include other parts within the 25LC160 family with compatible packages and electrical characteristics. Verify pinout compatibility and ensure that any substitute part supports the required SPI protocol and voltage levels. Check for availability of equivalent page sizes and temperature ratings.
