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)
