Device Identification Code Register
TMS470R1B768
16/32-Bit RISC Flash Microcontroller
SPNS108A–AUGUST 2005–REVISED AUGUST 2006
The device identification code register identifies the silicon version, the technology family (TF), a ROM or flash
device, and an assigned device-specific part number (see
Figure 3
). The B768 device identification code register
value is 0xn83Fh.

Description
Reads are undefined and writes have no effect.
Silicon version (revision) bits. These bits identify the silicon version of the device. Initial device
version numbers start at 0000. The current revision for the B768 device is 0000.
Technology family bit. This bit distinguishes the technology family core power supply:
3.3 V for F10/C10 devices
1.8 V for F05/C05 devices
ROM/flash bit. This bit distinguishes between ROM and flash devices:
Flash device
ROM device
Device-specific part number bits. These bits identify the assigned device-specific part number. The
assigned device-specific part number for the B768 device is 0001111.
Mandatory High
Bits 2, 1, and 0 are tied high by default.
