HPC46100 Datasheet, PDF (2/32 Pages) National Semiconductor (TI) – HPC46100 High-Performance microController with DSP Capability

General Description (Continued)
The HPC46100 has as an on-chip peripheral an 8-channel
8-bit Analog-to-Digital Converter This A D converter can
operate in a single-ended mode where the analog input volt-
age is applied across one of the eight input channels (D0–
D7) and AGND The A D converter can also operate in a
differential mode where the analog input voltage is applied
across two adjacent input channels The A D converter will
convert up to eight channels in the single-ended mode and
up to four channel pairs in the differential mode
A group of three high speed timers provide processor inde-
pendent PWM signal generation These timers and their
support logic provide independent control of PWM frequen-
cy and PWM duty cycle with a minimum resolution of 50 ns
when running at 40 MHz
The HPC46100 is upwards source code compatible with the
HPC family except for Decimal Add and Subtract
The HPC46100 is available in an 80-pin QFP package
