Introduction

The Motorola MC68HC705JJ7 and MC68HC705JP7 are EPROM versions of the MC68HC05JJ/JP Family of microcontrollers.

Features

• Low-Cost, HC05 Core MCU in 20-Pin Package (MC68HC705JJ7) or 28-Pin Package (MC68HC705JP7)

• 6160 Bytes of User EPROM (Including 16 Bytes of User Vectors)

• 224 Bytes of Low-Power User RAM (4 Transistors)

• 64 Bits of Personality EPROM (Serial Access)

• 16-Bit Programmable Timer with Input Capture and Output Compare

• 15-Stage Core Timer Including 8-Bit Free-Running Counter and 4-Stage Selectable Real-Time Interrupt Generator

• Simple Serial Input/Output Port (SIOP) with Interrupt Capability

• Two Voltage Comparators, One of Which Can be Combined with the 16-Bit Programmable Timer to Create a 4-Channel, SingleSlope A/D Converter

• Output of Voltage Comparator Can Drive Port Pin PB4 Directly Under Software Control

• 14 I/O Lines (MC68HC705JJ7) or 22 I/O Lines (MC68HC705JP7) Including High-Source/Sink Current Capability on 6 I/O Pins (MC68HC705JJ7) or 14 I/O Pins (MC68HC705JP7)

• Programmable 8-Bit Mask Option Register (MOR) to Select Mask Options Found in ROM-Based Versions

• MOR Selectable Software Programmable Pulldowns on All I/O Pins and Keyboard Scan Interrupt on Four I/O Pins

• Software Mask and Request Bit for IRQ Interrupt with MOR Selectable Sensitivity on IRQ Interrupt (Edge- and Level-Sensitive or Edge-Only)

• On-Chip Oscillator with Device Option of Crystal/Ceramic Resonator or RC Operation and MOR Selectable Shunt Resistor, Approximately 2 MΩ

• Internal Oscillator for Lower-Power Operation, Approximately 100 kHz (500 kHz Selected as Device Option)

• EPROM Security Bit1 to Aid in Locking Out Access to Programmable EPROM array

• MOR Selectable (COP) Watchdog System

• Power-Saving Stop and Wait Mode Instructions (MOR Selectable STOP Conversion to Halt and Option for Fast 16-Cycle Restart, and Power-On Reset)

• On-Chip Temperature Measurement Diode

• MOR Selectable Low-Voltage Inhibit to Reset CPU in Low-Voltage Conditions

• Illegal Address Reset

• Internal Steering Diode and Pullup Device on RESET Pin to VDD
