HPC167064/HPC467064 High-Performance
microController with a 16k UV Erasable CMOS EPROM
General Description
The HPC167064 is a member of the HPC 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 HPC167064
has a 16 kbyte, high-speed, UV-erasable, electrically pro-
grammable CMOS EPROM. This is ideally suited for appli-
cations where fast turnaround, pattern experimentation, and
code
confidentiality are important requirements. The
HPC167064 can serve as a stand-alone emulator for either
the HPC16064 or the HPC16083. Two configuration regis-
ters have been added for emulation of the different chips.
The on-chip EPROM replaces the presently available user
ROM space. The on-chip EPROM can be programmed via a
DATA I/O UNISITE. There are security features added to
the chip to implement READ, ENCRYPTED READ, and
WRITE privileges for the on-chip EPROM. These defined
privileges are intended to deter theft, alteration, or uninten-
tional destruction of user code. Each part is fabricated in
National’s advanced microCMOS technology. This process
combined with an advanced architecture provides fast, flex-
ible I/O control, efficient data manipulation, and high speed
computation.
The HPC devices are complete microcomputers on a single
chip. All system timing, internal logic, EPROM, RAM, and
I/O are provided on the chip to produce a cost effective
solution for high performance applications. On-chip func-
tions such as UART, up to eight 16-bit timers with 4 input
capture registers, vectored interrupts, WATCHDOG
TM logic
and MICROWIRE/PLUS TM provide a high level of system
integration. The ability to address up to 64k bytes of exter-
nal memory enables the HPC to be used in powerful appli-
cations typically performed by microprocessors and expen-
sive peripheral chips.
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 HPC167064 is available only in
68-pin LDCC package.
