• Tamper Resistance: Countermeasures against environmental, non-invasive, and invasive fault attacks
• Secure Key Management: Internal asymmetric key generation (private keys never exposed outside the device)

Ordering and Shipping Details

• Full Part Number: TA010-RBYCZT-VAO
• Part Number Breakdown
• Shipping Quantity: 5,000 units per reel
• Package Marking: Vague alphanumeric code (manufacturing lot information only; no device type/manufacturer details for security)

Trust Platform Variants and Provisioning

• Provisioning Services: Supported via Microchip Trust Platform (leverages Trust Platform Design Suite, TPDS)
• Available Flows for TA010: TrustFLEX (pre-configured with customer-unique credentials) and TrustCUSTOM (fully customizable)
• Note: TA010-RBYCZT-VAO follows the standard TA010 cryptographic and security framework; custom provisioning available via TrustCUSTOM flow.

Usage Guidelines and Precautions

• Mounting: For 3-Lead Contact package, Theta JA specifications apply when soldered to a board (typical use case may not require soldering)
• Sleep Mode Optimization: Drive inputs to VCC or use pull-up resistors for lowest sleep current
• SWI Parasitic Power Mode: CMOSen must be set to '1'; avoid CMOSen = '0' in this mode
• Safety Vent Caution: Ensure mounting does not obscure any device safety vents (if applicable)
• Package Disclaimer: UDFN package is deprecated for TA010; VDFN package is recommended (board land pattern is identical for UDFN/VDFN)
