AT89SC
THE VERSATILE SOLUTION
The AT89SC 8-bit microcontrollers
combine the proven MCS-51®and
MCS-251 architecture with up to 256
kilobytes of nonvolatile memory for
program and data. They offer a highly
flexible and cost-effective solution for
many Smart Card applications.
Based on the industry-standard
HC05 low-power MCU core,
the AT05SC family is upwards
compatible with the
established MSC series. It offers
a range of increased memory
sizes and enhanced security
features, as well as a dual-
interface contact/contactless
option. This makes the
AT05SC family one of the most
attractive product propositions
for single- and multi-function
applications from finance to
transport, health to pre-paid
mobile phone
communications.
BASED SECURE MICROCONTROLLERS AND CRYPTOCONTROLLERS
AT89SC FAMILY
Mobile phones. E-commerce. Healthcare cards. Pay television. Banking. Transport...
Our Flash- and ROM-based families of secure microcontrollers and cryptocontrollers
offer just the right features for all these applications. Atmel manufactures these low-
power high-performance devices using its high-density CMOS nonvolatile memory
technology.
FLASH- &ROM-
AT05SC FAMILY
Some products in the AT90SC family
feature a cryptoprocessor: a 16-bit
dedicated crypto-engine based on a
parallel RISC architecture. Running in
parallel with the AVR microcontroller
core, the SC16 generates complex
encryption and authentication
algorithms to ensure security for the
most sensitive Smart Card
applications.
