ICC IIDLE 800 30 Sleep Current ISLEEP Notes Output Low Voltage VOL 0.4 V When device is in active mode, VCC = 2.5 – 5.5V Output Low Current IOL 4 mA When device is in active mode, VCC = 2.5 – 5.5V, VOL = 0.4V ƟJA Theta JA 166 C/W SOIC (SSH) 173 C/W UDFN (MAH) 146 C/W RBH  2.4.1 VIH and VIL Specifications The input voltage thresholds when in sleep or idle mode are dependent on the V CC level as shown in the graph below. When the device is active (i.e. not in sleep or idle mode), the input voltage thresholds are different depending upon the state of TTLenable (bit 1) within the ChipMode byte in the Configuration zone of the EEPROM. When a common voltage is used for the ATECC508A VCC pin and the input pull-up resistor, then this bit should be set to a one, which permits the input thresholds to track the supply. If the voltage supplied to the VCC pin of the ATECC508A is different than the system voltage to which the input pull-up resistor is connected, then the system designer may choose to set TTLenable to zero, which enables a fixed input threshold according to the following table. The following applies only when the device is active: Table 2-5. VIL, VIH on All I/O Interfaces Parameter 8 Symbol Min Input Low Voltage VIL Input High Voltage VIH Typ Max Unit -0.5 0.5 V When device is active and TTLenable bit in configuration memory is zero; otherwise see above. 1.5 VCC + 0.5 V When device is active and TTLenable bit in configuration memory is zero; otherwise see above.

If properly configured, it can be used in all situations where the ATSHA204 or ATSHA204A is currently employed. Because the Configuration zone is larger, the personalization procedures for the device must be updated when personalizing the ATSHA204 or ATSHA204A. 3.2 Atmel ATECC108 ATECC508A is designed to be fully compatible with the ATECC108 and ATECC108A devices. If properly configured, can be used in all situations where ATECC108 is currently employed. In many situations, the ATECC508A can also be used in an ATECC108 application without change. The new revisions provide significant advantages as outlined below: New Features in ATECC108A vs. ATECC108 4   Intrusion Detection Capability, Including Gating Key Use New SHA Command, Also Computes HMAC  X.509 Certificate Verification Capability  Programmable Watchdog Timer Length   Programmable Power Reduction Shared Random Nonce and Key Configuration Validation (Gendig Command)  Larger Slot 8 which is Extended to 416 bytes Ordering Information Delivery Information Atmel Ordering Code (2) Package Form Quantity ATECC508A-SSHCZ-T Tape and Reel 4,000 per Reel ATECC508A-SSHCZ-B Bulk in Tubes 100 per Tube Tape and Reel 4,000 per Reel Interface Configuration Single-Wire 8-lead SOIC ATECC508A-SSHDA-T 2 IC ATECC508A-SSHDA-B Bulk in Tubes 100 per Tube ATECC508A-MAHCZ-T Single-Wire 15,000 per Reel ATECC508A-MAHDA-T Tape and Reel ATECC508A-MAHCZ-S Single-Wire 3,000 per Reel ATECC508A-MAHDA-S (1) ATECC508A-RBHCZ-T Notes: 1. 2. 2 IC 8-pad UDFN 2 IC 3-lead CONTACT Tape and Reel 5,000 per Reel Single-Wire Please contact Atmel for availability.
