Overview
The MSC0402 microcontroller (MCU) is a member of Atmel’s MSC04 family of single chip MCUs,
designed specifically for embedded conditional access systems and other security conscious
systems. It is based on the industry-standard M68HC05 low-power HCMOS core and gives
access to the powerful instruction set of this widely used family of devices.
Memory on-board the MSC0402 consists of 23K ROM, 384 bytes of RAM and 8K EEPROM,
which features 2ms programming, typically, more than 2,000,000 write/erase cycles, and greater
than 10 years data retention.
This circuit is designed in accordance with the ISO standard for integrated circuit cards (ISO
7816), and with the GSM specification 11.11 and 11.12, where appropriate.
The MSC0402 is currently available in sawn wafer form, and in industry-standard modules.
