The 32 Kbit memory holds keys, certificates, or configuration data alongside the secure authentication logic — the I2C bus speed of 1 MHz means it keeps up with a fast host controller without stalling the transaction. ## 8-SOIC package — board integration and supply rails Surface-mount assembly with tube delivery suits medium-volume production; the 8-SOIC outline is compatible with common pick-and-place nozzles and reflow profiles. ## Active lifecycle — no design-in risk The ROHS3 compliance covers the current regulatory requirements for EU and most global markets; no additional exemption documentation is needed for standard commercial use. ## Target applications — networking and communications gear The part is catalogued for Networking and Communications applications — think authenticated firmware updates, secure boot, or key storage in routers, switches, and IoT gateways where the I2C bus is already present.","metaTitle":"Microchip ATAES132A-SHER-B Authentication Chip, 32K I2C","metaDescription":"Microchip ATAES132A-SHER-B Authentication Chip, 32Kbit EEPROM with I2C interface, 1 MHz.
