MB89T637

* High-speed operating capability at low voltage
* Minimum execution time: 0.4 m s/3.5 V, 0.8 m s/2.7 V
* 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.
* Five types of timers
   8-bit PWM timer: 2 channels (Also usable as a reload timer)
   8-bit pulse-width count timer (Continuous measurement capable, applicable to remote control, etc.)
   16-bit timer/counter
   21-bit time-base timer
* UART
   CLK-synchronous/CLK-asynchronous data transfer capable (6, 7, and 8 bits)
* Serial interface
   Switchable transfer direction to allows communication with various equipment.
* 10-bit A/D converter
   Activation by an external input capable
* External interrupt: 4 channels
   Four channels are independent and capable of wake-up from low-power consumption modes (with an edge detection function).
* 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
* Bus interface function
   With hold and ready function

The MB89T637 series has been developed as a general-purpose version of the F²MC*-8L family consisting of proprietary 8-bit, single-chip microcontrollers.

In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as dual-clock control system, five operating speed control stages, a UART, timers, a PWM timer, a serial interface,an A/D converter, an external interrupt, and a watch prescaler.

*: F²MC stands for FUJITSU Flexible Microcontroller MB89T637.
