25C080-I/SN

Memory IC Overview

The Microchip Technology 25C080-I/SN is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM. It features a 3 MHz maximum clock frequency and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes an SPI-compatible serial bus for communication, supporting sequential reads and page writes up to 16 bytes. It offers high reliability with 1 million write cycle endurance and over 200 years of data retention. The component is housed in an 8-lead SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports block write protection allowing selective array segments to be protected against modification.
• Includes built-in power-on/off data protection circuitry and a write enable latch to prevent inadvertent writes.
• Features a hold pin that allows suspension of serial communication without resetting the sequence.

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter storage
• Calibration value retention

Memory IC Procurement Notes

Verify the specific suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'SN' indicates the 8-lead SOIC package. Confirm the datasheet revision matches the required specifications, as this device is marked as not recommended for new designs. Ensure compatibility with the 4.5 V to 5.5 V operating voltage range before procurement.

Memory IC Selection Notes

Select this component when a 5V-only SPI EEPROM is required for legacy systems or specific voltage domains. The 25C080 is distinct from the 25LC080 due to its higher minimum operating voltage. Consider the 16-byte page size limitation for write operations. Verify that the 3 MHz clock speed meets the system timing requirements.

Memory IC Part Context

The 25C080 is part of the 25XX080 family, which includes the 25AA080 and 25LC080 variants. These devices share similar functional architectures but differ in operating voltage and clock speed specifications. The 25C080 specifically targets applications requiring a 5V supply rail. The family provides non-volatile memory solutions accessible via standard SPI interfaces.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 25C080-E/SN (Extended Temperature Range). Note: This device is not recommended for new designs; consider 25AA080A/B or 25LC080A/B series for new projects.
