GENERAL DESCRIPTION
The DS2252T secure microcontroller module is
an 8051-compatible microcontroller based on
nonvolatile RAM technology. It is designed for
systems that need to protect memory contents
from disclosure. This includes key data, sensitive
algorithms, and proprietary information of all
types. Like other members of the secure
microcontroller
family,
it
provides
full
compatibility with the 8051 instruction set,
timers, serial port, and parallel I/O ports. By
using NV RAM instead of ROM, the user can
program, then reprogram the microcontroller
while in-system. This allows frequent changing of
sensitive processes with minimal effort.
PIN CONFIGURATION
Operating information and detailed summary of this product’s
security features are contained in the Secure Microcontroller
User’s Guide. This data sheet provides ordering information,
pinout, and electrical specifications.
