HPC167064/HPC467064 High-Performance microController with a 16k UV Erasable CMOS EPROM

HPC167064/HPC467064 with a 16k UV

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, WATCHDOGTM logic and MICROWIRE/PLUSTM 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.
