HPC167064 HPC467064 High-Performance microController
with a 16k UV Erasable CMOS EPROM
PRELIMINARY
August 1992
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鈥檚 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
