DESCRIPTION

The MB89140 series is a line of single-chip microcontrollers that use the F²MC-8L(F²MC stands for FUJITSU Flexible Microcontroller) CPU core which can operate at low voltage but at high speed. The MB89140 series contains a variety of peripheral functions, such as timers, a serial interface, an A/D converter, and an external interrupt. The MB89140 series is applicable to a wide range of applications from welfare products to industrial equipment, including portable devices.

FEATURES

• Minimum execution time: 0.5µs/8 MHz oscillation
• F²MC-8L family CPU core
• Instruction set optimized for controllers
  
  • Multiplication and division instructions
  • 16-bit arithmetic operations
  • Test and branch instructions
  • Bit manipulation instructions, etc.
• Low-voltage operation (when an A/D converter is not used)
• Low current consumption (compatible with dual-clock system)
• High-voltage ports on chip
• Five types of timers
  
  • 8-bit PWM timer (also usable as a reload timer)
  • 12-bit MPG timer (also usable as a PPG output, PWM output, and reload timer)
  • 8/16-bit timer (also usable as two 8-bit timers)
  • 21-bit time-base timer
• One serial interface: Swichable transfer direction allows communication with various equipment.
• 10-bit A/D converter: 12 channels(Successive approximation type)
• External interrupt: 2 channels: Two channels are independent and capable of wake-up from low-power consumption modes. (Rising edge,falling edge/both edges selectability)
• Low-power consumption modes:
  
  • Stop mode (Oscillation stops to minimize the current consumption.)
  • Sleep mode (The CPU stops to reduce the current consumption to approx. 1/3 of normal.)
  • Subclock mode
  • Watch mode
• Reset output and power-on reset selectability
