Product details

Microchip ATECC608B-MAHDA-T - ECC Secure Element

The {mpn} is Microchip's ECC-based CryptoAuthentication device: an asymmetric secure element built around NIST P-256 ECDSA/ECDH in hardware, with AES-128 and SHA-256 accelerators alongside. The private key is generated and used inside the chip and never leaves it, which makes the part a natural root of identity for IoT nodes, TLS clients and signed-firmware schemes. Package/interface: I2C interface, 8-pad UDFN (2 × 3 mm).

Key Features

  • Hardware ECC: NIST P-256 ECDSA sign/verify and ECDH key agreement
  • AES-128 and SHA-256 accelerators on the same die
  • 16 key/storage slots with per-slot cryptographic policies
  • Secure hardware key generation - private key never exposed
  • I2C interface up to 1 MHz; wide supply range across the family
  • NIST SP 800-90A/B/C compliant random number generator; tamper-resistant design

Frequently Asked Questions

Q: Why asymmetric instead of SHA204A?
A: With ECC the verifier holds only a public key - you can authenticate thousands of devices without storing a secret on the host, and the private key never exists outside the chip.

Q: ATECC608B vs ATECC608A?
A: Same crypto core; the B variant adds AES-128, updated counter protections and pre-provisioned cloud trust options (Google/AWS/Microsoft variants).

Q: Provisioning at scale?
A: Trust&GO / TrustFLEX variants arrive pre-configured for popular clouds; this standard part is configured by the customer during production.
