The ECC608A is a member of the Microchip CryptoAuthentication family of high-security cryptographic devices which combine world-class hardware-based key storage with hardware cryptographic accelerators to implement various authentication and encryption protocols.
The ECC608A includes an EEPROM array which can be used for storage of up to 16 keys, certificates, miscellaneous read/write, read-only or secret data, consumption logging, and security configurations. Access to the various sections of memory can be restricted in a variety of ways and then the configuration can be locked to prevent changes.
PIO | Mnemonic | Shared | Signal Description |
---|---|---|---|
PD19 | TWD1 | EEPROM TWI | TWI Data |
PD20 | TWCK1 | EEPROM TWI | TWI Clock |
ATECC608A-SSHDA is placed on the same TWI bus as the EEPROM memories and the three mikroBUS connectors.
