The MB95F656E is a series of general-purpose, single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers of this series contain a variety of peripheral functions
- F2MC-8FX CPU core Instruction set optimized for controllers
- Multiplication and division instructions
- 16-bit arithmetic operations
- Bit test branch instructions
- Bit manipulation instructions, etc. Note: F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
- Clock
- Selectable main clock source
- Main oscillation clock (up to 16.25 MHz, maximum machine clock frequency: 8.125 MHz)
- External clock (up to 32.5 MHz, maximum machine clock frequency: 16.25 MHz)
- Main CR clock (4 MHz ±2%)
- Main CR PLL clock
- The main CR PLL clock frequency becomes 8 MHz ±2% when the PLL multiplication rate is 2.
- The main CR PLL clock frequency becomes 10 MHz ±2% when the PLL multiplication rate is 2.5.
- The main CR PLL clock frequency becomes 12 MHz ±2% when the PLL multiplication rate is 3.
- The main CR PLL clock frequency becomes 16 MHz ±2% when the PLL multiplication rate is 4.
- Main PLL clock (maximum machine clock frequency: 16 MHz)
- Selectable subclock source
- Suboscillation clock (32.768 kHz)
- External clock (32.768 kHz)
- Sub-CR clock (Typ: 100 kHz, Min: 50 kHz, Max: 150 kHz)
- Timer
- 8/16-bit composite timer × 2 channels
- Time-base timer × 1 channel
- Watch prescaler × 1 channel
- UART/SIO × 1 channel (The channel can be used either as a UART/SIO channel or as an I2C bus interface channel.)
- The function of this channel can be switched between UART/SIO and I2C bus interface.
- Full duplex double buffer
- Capable of clock asynchronous (UART) serial data transfer and clock synchronous (SIO) serial data transfer
- I2C bus interface × 2 channels (One of the two channels can be used either as an I2C bus interface channel or as a UART/SIO channel.)
- Supports Standard-mode and Fast-mode (400 kHz).
- Built-in wake-up function
- LIN-UART
- Full duplex double buffer
- Capable of clock asynchronous serial data transfer and clock synchronous serial data transfer
- External interrupt × 6 channels
- Interrupt by edge detection (rising edge, falling edge, and both edges can be selected)
- Can be used to wake up the device from different low power consumption (standby) modes
- 8/12-bit A/D converter × 6 channels 8-bit or 12-bit resolution can be selected.
- Low power consumption (standby) modes There are four standby modes as follows:
- Stop mode
- Sleep mode
- Watch mode
- Time-base timer mode
- I/O port
- MB95F652E/F653E/F654E/F656E (number of I/O ports: 21)
- General-purpose I/O ports (CMOS I/O) : 17

- MB95F652L/F653L/F654L/F656L (number of I/O ports: 20)
- General-purpose I/O ports (CMOS I/O) : 17
- General-purpose I/O ports (N-ch open drain) : 3
- On-chip debug
- 1-wire serial control
- Serial writing supported (asynchronous mode)
- Hardware/software watchdog timer
- Built-in hardware watchdog timer
- Built-in software watchdog timer
- Power-on reset A power-on reset is generated when the power is switched on Built-in low-voltage detection function
- Clock supervisor counter Built-in clock supervisor counter
- Dual operation Flash memory The program/erase operation and the read operation can be executed in different banks (upper bank/lower bank) simultaneously.
- Flash memory security function Protects the content of the Flash memory
