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 programmable CMOS EPROM. This is ideally suited for applications 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 registers have been added for emulation of the different chips.

The on-chip EPROM replaces the presently available user ROM space of HPC167064. 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 unintentional destruction of user code. Each part is fabricated in National's advanced microCMOS technology. This process combined with an advanced architecture provides fast, flexible I/O control, efficient data manipulation, and high speed computation.

The HPC167064 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 functions 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 external memory enables the HPC to be used in powerful applications typically performed by microprocessors and expensive 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.
