8-bit Original Microcontroller CMOS

Fujitsu 

MB89530A Series

(Continued)

• Five timer systems

• 8-bit PWM timer with 2 channels (usable as either interval timer of PWM timer)

• Pulse width count timer (supports continuous measurement or remote control receiving applications)

• 16-bit timer counter

• 21-bit time base timer

• Watch prescaler (17-bit)

• UART

Synchronous or asynchronous operation, switchable

• 2 serial interfaces (Serial I/O)

Selection of transfer direction (specify MSB first or LSB first) for communication with a variety of devices

• 10-bit A/D converter (8 channels)

• External clock input for startup support

• Time base timer output for startup support (except MB89F538)

• Pulse generators (PPG) with 2-program capability

• 6-bit PPG with selection of pulse width and pulse period

• 12-bit PPG (2 channels) with selection of pulse width and pulse period

• I2C* interface circuits

• External interrupt 1 (single-clock system : 4 channels, dual-clock system : 3 channels)

4 or 3 independent inputs, release enabled from standby mode (includes edge detection function)

• External interrupt 2 (except for MB89F538 : 8 channels, MB89F538 : 7 channels)

8 or 7 independent input, release enabled form standby mode (includes level edge detection function)

• Standby modes (low power consumption modes)

• Stop mode (oscillator stops, virtually no power consumed)

• Sleep mode (CPU stops, power consumption reduced to one-third)

• Sub clock mode

• Watch mode

• Watchdog timer reset

• I/O ports

• Maximum ports

Single-clock system : Except MB89F538 53 ports

: MB89F538

52 ports

Dual-clock system : Except MB89F538 51 ports

: MB89F538

50 ports

• 38 general-purpose I/O ports (CMOS) (MB89F538 : 37 general-purpose I/O ports)

• 2 general-purpose I/O ports (N-ch open drain)

• 8 general-purpose output ports (N-ch open drain)

• General-purpose input ports (CMOS) : single-clock system : 5 ports, dual-clock system : 3 ports
