HPC46100 High-Performance microController
with DSP Capability
General Description
The HPC46100 is a member of the HPCTM family of High
Performance microControllers Each member of the family
has a similar core CPU with unique memory resources and
I O configuration to suit specific applications The
HPC46100 is fabricated in National’s advanced microCMOS
technology This process combined with an advanced archi-
tecture provides fast flexible I O control efficient data ma-
nipulation high speed computation and low power con-
sumption
Throughput is enhanced by operating the HPC46100 at fre-
quencies up to 40 MHz by integrating a Multiply Accumu-
late Unit (MAU) onto the chip and by optimizing instructions
to increase efficiency These features increase performance
in closed loop digital servo and filter applications
The HPC devices are complete microcomputers on a single
chip All system timing internal logic RAM and I O are
provided on the chip to produce a cost effective solution
for high performance applications On-chip functions
such as an MAU unit PWM outputs Chip Select Signals
UART up to seven 16-bit timers with input capture
capability WATCHDOGTM logic vectored interrupts and
MICROWIRE PLUSTM provide a high level of system inte-
gration The ability to directly address up to 64 kbytes of
memory enables the HPC to be used in powerful applica-
tions typically performed by microprocessors and peripheral
chips

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
