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 ATECC108A 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 ATECC108A 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:

Compatibility
3.1
Atmel ATSHA204
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
ATECC108A is designed to be fully compatible with the ATECC108. If properly configured, can be used in all
situations where ATECC108 is currently employed. In many situations, the ATECC108A 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
Intrusion Detection Capability, Including Gating Key Use
New SHA Command, Also Computes HMAC
X.509 Certificate Verification Capability
Programmable Watchdog Timer Length
Shared Random Nonce and Key Configuration Validation (Gendig Command)
Larger Slot 8 which is Extended to 416 bytes

1. This drawing is for general information only. Refer to
Drawing MO-229, for proper dimensions, tolerances,
datums, etc.
2. The Pin #1 ID is a laser-marked feature on Top View.
3. Dimensions b applies to metallized terminal and is
measured between 0.15 mm and 0.30 mm from the
terminal tip. If the terminal has the optional radius on
the other end of the terminal, the dimension should
not be measured in that radius area.
4. The Pin #1 ID on the Bottom View is an orientation
feature on the thermal pad.
