DS2250(T)
9 of 20
A typical parallel loading session would follow this procedure. First, set the contents of the MCON
register with the correct range and partition only if using expanded programming cycles. Next, the
encryption registers can be loaded to enable encryption of the program/data memory (not required). Then,
program the DS2250(T) using either normal or expanded program cycles and check the memory contents
using Verify cycles. The last operation would be to turn on the security lock feature by either a Security
Set cycle or by explicitly writing to the MCON register and setting MCON.0 to a 1.

ADDITIONAL INFORMATION
A complete description for all operational aspects of the DS2250(T) is provided in the User’s Guide
section of the Secure Microcontroller Data Book.
DEVELOPMENT SUPPORT
Dallas Semiconductor offers a kit package for developing and testing user code. The DS5000TK
Evaluation Kit allows the user to download Intel hex formatted code directly to the DS2250(T) from a
PC-XT/AT or compatible computer. The kit consists of a DS5000T-32-12, an interface pod, demo
software, and an RS232 connector that attaches to the COM1 or COM2 serial port of a PC. The kit can be
used with a DS2250(T). A mechanical adapter, the DS9075-40V, allows a DS2250(T) to be used in the
DS5000TK. See the Secure microcontroller User’s Guide for further details.
