Product Details
ATAES132A-MAHER-T - AES-CCM Secure EEPROM, UDFN
ATAES132A-MAHER-T from Microchip Technology is a 32-Kbit secure serial EEPROM with AES-128 authentication in an 8-pad 2 x 3 mm UDFN, on a 15,000-piece reel.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
ATAES132A provides 16 configurable user-memory zones, protected key storage and AES-CCM data authentication. MAHER-T selects I2C operation and large-reel UDFN packaging.
Key Advantages
AES-CCM authentication and protected EEPROM zones.
Compact 8-pad UDFN footprint.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
