The MB95F856K is a series of general-purpose, single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers of these series contain a variety of peripheral resources.
- 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 multiplier is 2. The main CR PLL clock frequency becomes 10 MHz ±2% when the PLL multiplier is 2.5. The main CR PLL clock frequency becomes 12 MHz ±2% when the PLL multiplier is 3. The main CR PLL clock frequency becomes 16 MHz ±2% when the PLL multiplier is 4.
- Selectable subclock source Sub-oscillation 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 PPG MB95F856K: 1 channel
- Time-base timer × 1 channel
- Watch counter × 1 channel
- Watch prescaler × 1 channel
- UART/SIO × 1 channel
- Full duplex double buffer
- Capable of clock-asynchronized (UART) serial data transfer and clock-synchronized (SIO) serial data transfer
- I2C bus interface × 1 channel
- Built-in wake-up function
- External interrupt
- MB95F856K: 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
- 8/10-bit A/D converter
- MB95F856K: 4 channels
- 8-bit or 10-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 In standby mode, two further options can be selected: normal standby mode and deep standby mode.
- I/O port
- MB95F856K (no. of I/O ports: 21) General-purpose I/O ports (CMOS I/O) : 17 General-purpose I/O ports (N-ch open drain) : 4

- 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.
- Low-voltage detection (LVD) reset circuit
- Built-in low-voltage detection function (The combination of detection voltage and release voltage can be selected from four options.)
- Comparator × 1 channel
- Built-in dedicated BGR
- The comparator reference voltage can be selected between the BGR voltage and the comparator pin.
- 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.
- Touch sensor (TS)
- Adjacent Pattern Interference Suppression (APIS™)
- Three modes in APIS: APIS mode 1, APIS mode 2 and APIS mode 3
- Configurable Automatic Impedance Calibration (AIC™)
