25LC080CT-I/MNY

Overview

The Microchip Technology 25LC080CT-I/MNY is an 8 Kbit (1024 x 8) Serial Electrically Erasable PROM. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz via a standard SPI interface. The device features a 16-byte page size, self-timed write cycles with a maximum duration of 5 ms, and industrial temperature ratings from -40°C to +85°C. Packaged in an 8-lead TDFN format, it offers high reliability including over 1 million erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Supports serial communication through a four-wire SPI compatible bus with separate data input and output lines.
• Includes programmable block write protection allowing selection of none, one-quarter, one-half, or the entire array.
• Features built-in power-on/off data protection circuitry combined with a write enable latch for secure operations.
• Provides a hold function that pauses serial transmission without resetting the sequence, facilitating interrupt handling.

Applications

• Data storage for configuration parameters in microcontroller systems
• Logging operational history or event records in embedded devices
• Storing calibration constants and device identifiers

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range of -40°C to +85°C and 'MNY' denotes the 8-lead TDFN package. Confirm the 'C' variant designation indicates the 16-byte page size requirement for your application software. Ensure supply chain sources provide original manufacturer documentation to validate RoHS compliance and Pb-free status before integration.

Selection Notes

Select this component when a non-volatile memory solution requires low-power CMOS technology and robust data retention specifications. It is suitable for designs needing hardware write protection mechanisms and sequential read capabilities. Consider the 16-byte page limitation for write efficiency compared to larger page sizes available in other variants within the same family.

Part Context

This part belongs to the 25XX080C/D family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'LC' prefix specifies a 2.5 V minimum operating voltage, distinguishing it from the 'AA' series which supports lower voltages down to 1.8 V. The 'C' suffix identifies the device architecture utilizing a 16-byte page buffer for write operations.

Replacement Considerations

The 25LC080DT-I/MNY serves as a direct functional substitute within the same package and feature set, differing only in its 32-byte page size specification.
