High-Performance microController with A D
General Description
The HPC46164 and HPC46104 are members of the HPC
TM
family of High Performance microControllers Each member
of the family has the same core CPU with a unique memory
and I O configuration to suit specific applications The
HPC46164 has 16k bytes of on-chip ROM The HPC46104
has no on-chip ROM and is intended for use with external
memory Each part is fabricated in National鈥檚 advanced
microCMOS technology This process combined with an ad-
vanced architecture provides fast flexible I O control effi-
cient data manipulation and high speed computation
The HPC devices are complete microcomputers on a single
chip All system timing internal logic ROM RAM and I O
are provided on the chip to produce a cost effective solution
for high performance applications On-chip functions such
as UART up to eight 16-bit timers with 4 input capture regis-
ters vectored interrupts WATCHDOG
TM
logic and MICRO-
WIRE PLUS
TM
provide a high level of system integration
The ability to address up to 64k bytes of external memory
enables the HPC to be used in powerful applications typical-
ly performed by microprocessors and expensive peripheral
chips The term 鈥樷€楬PC46164鈥欌€?is used throughout this data-
sheet to refer to the HPC46164 and HPC46104 devices un-
less otherwise specified
The HPC46164 and HPC46104 have as an on-board pe-
ripheral an 8-channel 8-bit Analog-to-Digital Converter This
A D converter can operate in a single-ended mode where
the analog input voltage is applied across one of the eight
input channels (D0鈥揇7) and AGND The A D converter can
also operate in 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 single-
ended mode and up to four channel pairs in differential
mode
The microCMOS process results in very low current drain
and enables the user to select the optimum speed power
product for his system The IDLE and HALT modes provide
further current savings The HPC is available only in an
80-pin PQFP package
