High-Performance microControllers
General Description
The HPC16083 and HPC16003 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
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’s 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 ‘‘HPC16083’’ 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.
