25LC320AT-I/MNY16KVAO

Overview

The Microchip Technology 25LC320AT-I/MNY16KVAO is a 32-Kbit Serial Electrically Erasable PROM featuring a 4096 x 8-bit organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It includes a 32-byte page buffer, self-timed erase/write cycles, and block write protection capabilities.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write-protect pin and software programmable block protection
• Features power-on/off data protection circuitry and write enable latch
• Provides hold functionality to pause serial transmission without resetting the sequence

Applications

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

Procurement Notes

Verify that the specific suffix '16KVAO' corresponds to the standard 25LC320A family specifications documented in datasheet DS20001828H. Confirm package type matches the 8-Lead MSOP format listed for the I-grade variant. Ensure operating conditions align with the specified 2.5V to 5.5V voltage range and industrial temperature limits.

Selection Notes

Select this component when an SPI interface is required for non-volatile memory with moderate density. It is suitable for applications needing hardware write protection and low standby current. Compare against the 25AA320A if lower voltage operation down to 1.8V is necessary. Verify compatibility with existing SPI bus protocols and microcontroller GPIO configurations.

Part Context

This part belongs to the 25XX320A series of 32-Kbit Serial EEPROMs manufactured by Microchip Technology. The series shares identical functional characteristics and instruction sets across different voltage grades and packaging options. The 'I' designation indicates industrial temperature rating, while 'MNY' specifies the MSOP package style.

Replacement Considerations

The 25LC320A-I/SN is a confirmed equivalent within the same family offering identical electrical and functional specifications in an SOIC package.
