Current Development Tools
Hardware Emulation Module (for the Motorola MMDS05 Development System)
– Emulation Module (AT05SC3208R-EM3)
Description
The AT05SC3208R is a member of Atmel’s AT05SC family of single chip microcontrollers. Designed specifically for Smart-
cards, 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 AT05SC3208R 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 32768 bytes of ROM, 1024 bytes of RAM and 8192 bytes of EEPROM. The EEPROM fea-
tures 64-byte write, 2 ms program time, 2 ms erase time, typically more than 1,000,000 write/erase cycles, and greater
than 10 years data retention. Application areas for the AT05SC3208R include GSM Mobile Phones, Finance and Set-top
Boxes.
