What are the key features of 24C32ASN?
- 32 Kbit (4 KB) I2C EEPROM with 400 kHz fast-mode bus support
- 32-byte page write buffer for efficient sequential data writes
- Up to 1,000,000 erase/write cycles per byte ensuring long service life
- Hardware write-protect pin for data security in critical storage applications
- 8-pin SOIC package with 3 address pins supporting up to 8 devices on one I2C bus
What is 24C32ASN used for?
The 24C32ASN is commonly used to store firmware configuration, sensor calibration constants, and system parameters in embedded products such as smart meters, industrial sensors, and consumer appliances. Its 400 kHz I2C interface and 32-byte page write capability allow quick bulk writes from a microcontroller during factory programming or field updates. The device also serves as a small event log or hour-meter storage in HVAC controllers and motor drives where non-volatile retention over 200 years ensures data integrity across the product lifetime.

Frequently Asked Questions
Which designs can use 24C32ASN when 8 pins is a required parameter?
24C32ASN is a practical fit when the design needs 8 pins in a integrated circuit from Microchip. Buyers should confirm the package, lifecycle state, and original datasheet before approving it for production builds.
How should buyers compare 24C32ASN with alternate integrated circuit options?
Use 32A as one verified requirement, then match the electrical ratings, footprint, and manufacturer series against the target BOM. This reduces substitution risk when similar parts differ in assembly or operating limits.
Which assembly detail should be checked before sourcing 24C32ASN for production?
Confirm that the selected lot matches Small Outline Packages and the known 32 Kb requirement before RFQ approval. This gives incoming inspection and engineering teams a clearer basis for footprint, mating, or thermal review.
