INTRODUCTION
MOTOROLA
1-1
SECTION 1
INTRODUCTION
The MC68HC705J2 is a member of the low-cost, high-performance M68HC05
Family of 8-bit microcontroller units (MCUs). The high-density, complementary
metal-oxide semiconductor (HCMOS) M68HC05 Family is based on the
customer-specified integrated circuit (CSIC) design strategy. All MCUs in the
family use the popular M68HC05 central processor unit (CPU) and are
available with a variety of subsystems, memory sizes and types, and package
types.
The MC68HC705J2 is an expansion of the MC68HC05J1 design. On-chip
memory is enhanced with 2 Kbytes of erasable, programmable ROM (EPROM),
112 Kbytes of RAM, and a bootloader ROM.
1.1 Features

Popular M68HC05 CPU
Memory-Mapped Input/Output (I/O) Registers
2064 Bytes of User EPROM Including 16 User Vector Locations
112 Bytes of Static RAM (SRAM)
14 Bidirectional I/O Pins
Fully Static Operation With No Minimum Clock Speed
On-Chip Oscillator With Crystal/Ceramic Resonator Connections
15-Bit Multifunction Timer
Real-Time Interrupt Circuit
Bootloader ROM
Power-Saving STOP, WAIT, and Data Retention Modes
MC68HC05J1 Emulation Mode
