Description
The H8/300L Series is a single-chip microcomputer (MCU: microcomputer unit), built around the high-speed H8/300L CPU and equipped with peripheral system functions on chip.The H8/3724 and H8/3754 Series are single-chip microcomputers in the H8/300L Series equipped with high-voltage pins. Their on-chip peripheral functions include a vacuum fluorescent display (VFD) controller/driver, timers, a 14-bit PWM (pulse width modulator), two serial communication interface channels, and an analog-to-digital converter. Together these functions make this chip ideally suited to use as a microcontroller in embedded systems requiring a VFD display.
- General registers: Sixteen 8-bit registers (can be used as eight 16-bit registers)
- Max. operating speed: 4.19 MHz
- Add/subtract: 0.5 µs (operating at f = 4 MHz)
- Multiply/divide: 3.5 µs (operating at f = 4 MHz)
- Can run on 32 kHz sub clock
- Instruction set compatible with H8/300 CPU
- Instruction length of 2 bytes or 4 bytes
- Basic arithmetic operations between registers
- MOV instruction for data transfer between memory and registers
- Multiply (8 bits × 8 bits)
- Divide (16 bits ÷ 8 bits)
- Bit accumulator
- Register-indirect designation of bit position
