Overview
The Microchip Technology 25CS320-I/SN is a 32-Kbit (4,096 x 8 bit) Serial EEPROM utilizing an SPI-compatible bus. It features a 32-byte page size and supports byte or sequential reads and writes. The device operates within a voltage range of 1.7V to 5.5V, with clock frequencies up to 20 MHz at VCC ≥ 4.5V. It includes a Security Register with a preprogrammed 128-bit serial number and user-programmable ID space. Built-in ECC logic corrects single-bit errors per four-byte readout. The Industrial temperature grade (-40°C to +85°C) ensures reliability in demanding environments.
Feature Summary
- Integrated Error Correction Code (ECC) logic for data integrity
- Configurable Enhanced Write Protection with independent memory partitions
- Preprogrammed globally unique 128-bit serial number
- Programmable Undervoltage Lockout Detection (UVLO)
Applications
- Automotive systems requiring AEC-Q100 qualified components
- Industrial control systems needing reliable nonvolatile storage
- Consumer electronics requiring secure device identification
Procurement Notes
Verify the 'I' suffix confirms the Industrial temperature range (-40°C to +85°C). Confirm the '/SN' suffix corresponds to the 8-Lead SOIC package. Ensure the specific revision matches the required datasheet version DS20006923B. Cross-reference the JEDEC Manufacturer ID for authenticity.
Selection Notes
Select this component when SPI interface compatibility with legacy devices like 25AA320A is required. Choose the Industrial grade for standard operating temperatures. Consider the Enhanced Write Protection mode if complex partitioning is needed. Verify voltage requirements align with the 1.7V to 5.5V operational range.
Part Context
This part belongs to the 25CS series of Serial EEPROMs from Microchip Technology. It is backward compatible with 25LC320A and AT25320B devices. The series is designed for applications requiring high reliability, security features, and robust write protection mechanisms across various industrial and automotive environments.
Replacement Considerations
Direct backward compatible replacements include the 25AA320A, 25LC320A, and AT25320B. Verify pinout and opcode compatibility before substitution. Ensure the replacement meets the same temperature and voltage specifications.
