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)
