The AT05SC1604R is a member of Atmel’s AT05SC family of single chip microcontrollers. Designed specifically for embedded conditional access systems and other security conscious systems, these devices are based on the industry-standard
M68HC05 low-power core and its instruction set.
The AT05SC1604R is designed to give a high level of protection against physical and power analysis attacks, and includes
hardware features to assist in protecting against SPA and DPA attacks. On-board CRC and RNG modules are provided to
assist in the design of high-security applications.
On-board memory comprises 16K bytes of ROM, 1K bytes of RAM and 4K bytes of EEPROM. The EEPROM features 64byte write, 4 ms program time, 4 ms erase time, typically more than 1,000,000 write/erase cycles, and greater than
10 years data retention.
Application areas for the AT05SC1604R include Health, Social Security and Benefit Cards, Finance and Payment Systems,
Driving Licences and ID cards.
