DSP16410C Digital Signal Processor
1 Introduction
3 Device Identification
This addendum contains information specific to the
DSP16410C. The DSP16410C is pin-compatible and
functionally identical to the DSP16410B. However, the
DSP16410C provides higher speed operation and
lower power dissipation than the DSP16410B. This
document describes the differences between the
DSP16410B and the DSP16410C. It should be used
as a supplement to the DSP16410B Digital Signal Pro-
cessor Data Sheet (DS01-070WTEC).
2 Features
The DSP16410C has different JTAG identification
numbers for each core. These identifiers are different
from those of the DSP16410B and can be accessed
through the JTAG port of each core. Table 1 lists the
JTAG identification numbers for each core of the
DSP16410C.

s High performance:
— Up to 800 million MACS per second at 200 MHz
s Low power:
— 1.575 V internal supply for power efficiency
— 3.3 V I/O pin supply for compatibility
s Changes from the DSP16410B to the DSP16410C:
— Maximum processor speed has changed from
185 MHz to 200 MHz
— Nominal internal supply voltage changed from
1.8 V to 1.575 V
— New JTAGID register settings for both cores
