High-Performance microControllers
General Description
The HPC16083 and HPC16003 are members of the
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
HPC16083 has 8k bytes of on-chip ROM The HPC16003
has no on-chip ROM and is intended for use with external
direct memory Each part is fabricated in National鈥檚 ad-
vanced microCMOS technology This process combined
with an advanced architecture provides fast flexible I O
control efficient data manipulation and high speed compu-
tation
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PC16083鈥欌€?is used throughout this data-
sheet to refer to the HPC16083 and HPC16003 devices un-
less otherwise specified
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 in 68-pin
PLCC LDCC PGA and 80-Pin PQFP packages
