High-performance Microcontroller With A 16k Uv Erasable Cmos Eprom

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 Nationals advanced microCMOS technology. This process combined with an advanced architecture provides fast, flex- ible I/O control, efficient data manipulation, and high speed computation. By National Semiconductor Corporation
