1 / 34 page TLDD11046 PRELIMINARY August 1992 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 Features Y HPC familycore features 16-bit architecture both byte and word operations 16-bit data bus ALU and registers 64 kbytes of direct memory addressing FAST200 ns for fastest instruction when using 200 MHz clock 134 ns at 300 MHz High code efficiencymost instructions are single byte 16 x 16 multiply and 32 x 16 divide Eight vectored interrupt sources Four 16-bit timercounters with 4 synchronous out- puts and WATCHDOG logic MICROWIREPLUS serial IO interface CMOSvery low power with two power save modes IDLE and HALT Y 16 kbytes high speed UV erasable electrically program- mable CMOS EPROM Y Stand-alone emulation of HPC16083 and HPC16064 family Y EPROM and configuration bytes programmable by DATA IO UNISITE with Pinsite Module Y Four selectable levels of security to protect on-chip EPROM contents Y UARTfull duplex programmable baud rate Y Four additional 16-bit timercounters with pulse width modulated outputs Y Four input capture registers Y 52 general purpose IO lines (memory mapped) Y Commercial (0 Cto a70 C) and military (b55 Cto a 125 C) temperature ranges for 200 MHz commercial (0 Cto a70 C) for 300 MHz Block Diagram (HPC167064 with 16k EPROM shown) TLDD11046 – 1 Series 32000 and TRI-STATE are registered trademarks of National Semiconductor Corporation MICROWIREPLUSTM and WATCHDOGTM are trademarks of National Semiconductor Corporation UNIX is a registered trademark of AT T Bell Laboratories IBM and PC-AT are registered trademarks of International Business Machines Corp SunOSTM is a trademark of Sun Microsystems C1995 National Semiconductor Corporation RRD-B30M105Printed in U S A |
