  • Low-cost, M68HC05 core MCU in 28-pin package 
  •  (MC68HC705JP7)
  • • 6160 bytes of user EPROM, including 16 bytes of user vectors
  • • 224 bytes of low-power user random-access memory (RAM)
  • • 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, single-slope 
  • analog-to-digital (A/D) converter
  • • Output of voltage comparator can drive port pin PB4 directly under
  • software control
  • •  22 I/O line
  • , including high-source/sink current capability 
  • on 14 I/O pins (MC68HC705JP7)
  • • Programmable 8-bit mask option register (MOR) to select mask 
  • options found in read-only memory (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 resistor-capacitor (RC) operation and MOR selectable shunt 
  • resistor, 2 MΩ by design
