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 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
