Overview
The MSC0406 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 Motorola M68HC05 low-power HCMOS core and
gives access to the powerful instruction set of this widely used family of devices.
Memory on-board the MSC0406 consists of 9K ROM, 240 bytes of RAM and 1.3K 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). The MSC0406 is currently available in sawn wafer form, and in industry-standard modules.
The block diagram for the MSC0406 is shown in
Figure 2-1
.
Caution:
A sampling/smoothing algorithm MUST be used in conjunction
with the RNG to obtain statistically random results across all
operating conditions (see
11 Random number generator
on
page 42).
