It stores configuration parameters, calibration tables, device IDs, or small data logs that need non-volatile retention through power cycles. Access time is 900 ns, which is standard for this density class and gives the host microcontroller adequate timing margin for back-to-back reads. ROHS3 compliant. ## Package and footprint Housed in an 8-SOIC wide-body package (0.209\" body width, 5.30 mm), the 24LC32AT/SM uses the SOIJ footprint variant. Surface-mount only. The wide-body is the same footprint as the standard 8-SOIC narrow but with a wider body — check your land pattern if migrating from a narrow SOIC design. ## Temperature grade and environment Intended for indoor, temperature-controlled equipment — office peripherals, consumer electronics, appliance control boards, and similar environments where the ambient stays above freezing and below 70°C. Not specified for industrial or automotive extended-temperature operation.","metaTitle":"Microchip 24LC32AT/SM 32Kbit I2C EEPROM, 400 kHz, 8-SOIC","metaDescription":"Microchip 24LC32AT/SM serial EEPROM: 32Kbit (4K x 8), I2C interface, 400 kHz clock, 900 ns access, 2.5V-5.5V supply, 8-SOIC wide.
