DESCRIPTION

The MB89580B/BW series is a line of general-purpose, single-chip microcontrollers. In addition to a compact instruction set, these microcontrollers contain a variety of peripheral functions, such as PLL clock control, timers, a serial interface, a PWM timer, and the USB function. In particular, these microcontrollers contain one USB function channel to support both high and low speeds.

FEATURES

• Package Type
  
  • 64-pin LQFP package (0.5 mm pitch) and 64-pin QFP package (0.65 mm pitch)
• High-speed operations at low voltage
  
  • Minimum execution time : 0.33µs (Automatically generates a 12 MHz main clock and a 48 MHz USB interface synchronization clock with an externally supplied 6 MHz clock and the internal PLL circuit.)
• F²MC-8L CPU core: Instruction set that is optimum to the controllers
  
  • Multiplication and division instructions
  • 16-bit arithmetic operations
  • branch instructions by bit testing
  • bit manipulation instructions, etc.
• PLL clock control
  
  • The internal PLL clock circuit allows the use of low-speed clocks which are advantageous to noise characteristics.
  • (6 MHz externally-supplied clock : Internal system clock oscillated at 12 MHz)
• Various timers
  
  • 8-bit PWM timer (can be used as either 8-bit PWM timer x 2 channels or PPG timer x 1 channel)
  • Internal 21-bit timebase timer
• Internal USB transceiver circuit (Compatible with high and low speeds)
• USB function
  
  • Compliant to USB Protocol Revision 1.0
  • Support for both low and full speeds (selectable)
  • Allows four endpoints to be specified at maximum.
  • Types of transfer supported : control/interrupt/bulk/isochronous
  • Built-in DMAC (Maps the buffer for each endpoint on to the internal RAM to directly access the memory for function's send and receive data.)
• UART/serial interface
  
  • Built-in UART/SIO function (selectable by switching)
• External interrupt
  
  • External interrupt (level detection x 8 channels)
  • Eight inputs are independent of one another and can also be used for resetting from low-power consumption mode (the L-level detection feature available).
• Low power consumption (standby mode supported)
  
  • Stop mode (There is almost no current consumption since oscillation stops.)
  • Sleep mode (This mode stops the running CPU.)
• A maximum of 53 general-purpose I/O ports
  
  • General-purpose I/O ports (CMOS) : 34
  • General-purpose output ports (CMOS) : 8
  • General-purpose I/O ports (Nch open drain) : 3
  • General-purpose input ports (CMOS 3.3 V input-compatible) : 8
• Parallel ports
  
  • Also serve as eight of the general-purpose I/O ports (CMOS)
  • Interrupt function available
  • Allows asynchronous read and write by external signals
• Power supply
  
  • Supply voltage : 3.0 to 5.5 V
