HPC167064HPC467064 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 IO

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 IO 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 IO 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

IO 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 WATCHDOGTM logic

and MICROWIREPLUSTM 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 speedpower

product for his system The IDLE and HALT modes provide

further current savings The HPC167064 is available only in

68-pin LDCC package
