Description
The AT05SC1602R is a new member of Atmel’s AT05SC
family of single-chip microcontrollers. Designed specifically
for embedded conditional access systems and other secu-
rity conscious systems, these devices are based on the
industry-standard M68HC05 low-power core and its
instruction set, and are manufactured in Atmel’s standard
0.35μ process technology.
The AT05SC1602R is designed to give a high level of pro-
tection 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, 512 bytes
of RAM and 2K bytes of EEPROM. The EEPROM features
64-byte write, 1 ms program time, 1 ms erase time, typi-
cally more than 1,000,000 write/erase cycles, and greater
than 10 years data retention.
Application areas for the AT05SC1602R include
Debit/Credit Cards, Electronic Purse, Health Cards and
Loyalty Cards.
