Functional Modes of Operation There are two primary functional modes of operation for the HPC167064. # EPROM Mode # Normal Running Mode EPROM MODE In the EPROM mode, the HPC167064 is configured to ‘‘ap- proximately emulate’’ a standard NMC27C256 EPROM.
Functional Modes of Operation (Continued) Security Level 2 This security level prevents programming of the on-chip EPROM or the ECON registers thereby providing WRITE protection. Read accesses to the on-chip EPROM or ECON registers may be accomplished without constraint in EPROM.
Pin Descriptions The HPC167064 is available only in 68-pin LDCC package. I/O PORTS Port A is a 16-bit bidirectional I/O port with a data direction register to enable each separate pin to be individually de- fined as an input or output. When accessing external memo- ry, port A is used as the multiplexed address/data bus.
Connection Diagram TL/DD/11046 – 17 Top View Order Number HPC167064, EL See NS Package Number EL68C Port sA&B The highly flexible A and B ports are similarly structured. The Port A (see Figure 11 ), consists of a data register and a direction register.

HPC167064 Operating Modes SINGLE CHIP NORMAL MODE In this mode, the HPC167064 functions as a self-contained microcomputer (see Figure 15 ) with all memory (RAM and EPROM) on-chip. It can address internal memory only, con- sisting of 16 kbytes of EPROM (C000 to FFFF) and 512 bytes of on-chip RAM and Registers (0000 to 02FF).

Timer Overview (Continued) (Clock Input/16) rate. It is used for WATCHDOG logic, high speed event capture, and to exit from the IDLE mode. Con- sequently, it cannot be stopped or written to under software control. Timer T0 permits precise measurements by means of the capture registers I2CR, I3CR, and I4CR.
Timer Overview (Continued) Maximum output frequency for any timer output can be ob- tained by setting timer/register pair to zero. This then will produce an output frequency equal to (/2 the frequency of the source used for clocking the timer. Timer Registers There are four control registers that program the timers.
MICROWIRE/PLUS Application Figure 25 illustrates a MICROWIRE/PLUS arrangement for an automotive application. The microcontroller-based sys- tem could be used to interface to an instrument cluster and various parts of the automobile. The diagram shows two HPC167064 microcontrollers interconnected to other MICROWIRE peripherals.
HPC167064 UART The HPC167064 contains a software programmable UART. The UART (see Figure 26 ) consists of a transmit shift regis- ter, a receiver shift register and five addressable registers, as foll.
Universal Peripheral Interface The Universal Peripheral Interface (UPI) allows the HPC167064 to be used as an intelligent peripheral to anoth- er processor. The UPI could thus be used to tightly link two HPC167064’s and set up systems with very high data ex- change rates.

Design Considerations (Continued) Designs using the HPC family of 16-bit high speed CMOS microcontrollers need to follow some general guidelines on usage and board layout. Floating inputs are a frequently overlooked problem. CMOS inputs have extremely high impedance and, if left open, can float to any voltage.
HPC167064 CPU The HPC167064 CPU has a 16-bit ALU and six 16-bit regis- ters. Arithmetic Logic Unit (ALU) The ALU is 16 bits wide and can do 16-bit add, subtract and shift or logic AND, OR and exclusive OR in one timing cycle. The ALU can also output the carry bit to a 1-bit C register.

Code Efficiency One of the most important criteria of a single chip microcon- troller is code efficiency. The more efficient the code, the more features that can be put on a chip.
Development Support (Continued) PROGRAMMING SUPPORT The HPC167064 EPROM array can be programmed using a DATA I/O Unisite model with a pinsite module. No adaptor board is required with the DATA I/O programmer. Program- ming of the configuration bytes and security bits is de- scribed in the HPC Family User’s Manual.
Part Selection The HPC family includes devices with many different options and configurations to meet various application needs. The number HPC167064 has been generically used throughout this datasheet to represent the whole family of parts. The following chart explains how to order various options available when ordering HPC family members.
