SECTION 1
INTRODUCTION
1.1
GENERAL
The MC68HC05G3 (705G4) is an 80-pin microcontroller unit (MCU) with highly
sophisticated on-chip peripheral functions. The memory map of MC68HC05G3 (ROM
device) includes 24 Kbytes of user ROM and 768 bytes of RAM. The memory map of
MC68HC705G4 erasable programmable read-only memory (EPROM device) includes 32
Kbytes of user EPROM and 1 Kbyte of RAM. The MCU has nine ports: A, B, C, D, E, F, G,
H, and J. Ports A, C, D, E, G, and H each have eight input-output (I/O) pins, ports B and F
each have eight input-only pins, and port J has four output-only pins. The MC68HC05G3
includes a time-based circuit, 8- and 16-bit timers, an 8-bit pulse width modulator, a
computer operating properly (COP) watchdog timer, an 8-bit analog/digital (A/D) converter,
eight key wakeup interrupts, and two serial peripheral interfaces.
