• Manufacturer Part Number: dsPIC33FJ32MC204
• Description: (dsPIC33FJ16MC304 / dsPIC33FJ32MC20x) 16-bit Microcontrollers
• Manufacturer: Microchip Technology

20.8
The
dsPIC33FJ16MC304 devices offer the intermediate
implementation of CodeGuard™ Security. CodeGuard
Security enables multiple parties to securely share
resources (memory, interrupts and peripherals) on a
single chip. This feature helps protect individual
Intellectual Property in collaborative system designs.

Preliminary
When coupled with software encryption libraries, Code-
Guard™ Security can be used to securely update Flash
even when multiple IPs reside on the single chip.
The code protection features are controlled by the
Configuration registers: FBS and FGS.
Secure segment and RAM protection is not imple-
mented
