High-Performance microController with AD

General Description

family of High Performance microControllers Each member

of the family has the same core CPU with a unique memory

and IO 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’s advanced

microCMOS technology This process combined with an ad-

vanced architecture provides fast flexible IO 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 IO

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-

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 ‘‘HPC46164’’ 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

AD converter can operate in a single-ended mode where

the analog input voltage is applied across one of the eight

input channels (D0 – D7) and AGND The AD converter can

also operate in differential mode where the analog input

voltage is applied across two adjacent input channels The

AD 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 speedpower

product for his system The IDLE and HALT modes provide

further current savings The HPC is available only in an

80-pin PQFP package
