Overview
The Microchip Technology 25LC080A-I/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM. It features a 16-byte page size and operates via a standard SPI-compatible serial bus with SCK, SI, SO, CS, HOLD, and WP pins. The device supports a maximum clock frequency of 10 MHz and functions within a supply voltage range of 2.5 V to 5.5 V. It is housed in an 8-lead MSOP package and rated for industrial temperatures from -40°C to +85°C.
Feature Summary
- Supports self-timed write cycles with a maximum duration of 5 ms.
- Includes block write protection allowing selection of none, 1/4, 1/2, or all array segments.
- Features built-in power-on/off data protection and a write enable latch mechanism.
Applications
- Microcontroller system configuration storage
- Calibration parameter retention
- Data logging applications
Procurement Notes
Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the 'MS' designation corresponds to the 8-lead MSOP package type. Ensure the 'A' version indicates the 16-byte page size rather than the 32-byte page size found in 'B' versions. Cross-reference the datasheet revision to confirm pinout consistency.
Selection Notes
Select this component when an 8 Kbit non-volatile memory solution is required with low pin count. The 2.5 V minimum operating voltage makes it suitable for mid-range logic systems. The MSOP package is appropriate for space-constrained surface-mount designs requiring through-hole alternatives like PDIP are not feasible.
Part Context
This part belongs to the 25LC080A/B series of 8 Kbit SPI EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 25AA080A but differs in its lower minimum operating voltage requirement of 2.5 V compared to the 1.8 V capability of the AA variant.
Replacement Considerations
The 25LC080A-E/MS serves as a direct replacement offering an extended automotive temperature range up to +125°C while maintaining identical electrical characteristics and pinouts.
