MB95810K Series
New 8FX 8-bit Microcontrollers
The MB95810K Series 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.

❐ Time-base timer  1 channel
❐ Watch prescaler  1 channel
■ UART/SIO  1 channel
❐ Full duplex double buffer
❐ Capable of clock asynchronous (UART) serial data transfer
and clock synchronous (SIO) serial data transfer
■ I²C bus interface  1 channel
❐ 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  12 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  12 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 (no. of I/O ports: 58)
❐ General-purpose I/O ports (CMOS I/O): 54
❐ General-purpose I/O ports (N-ch open drain): 4
■ On-chip debug

❐ 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
❐ The LVD function is enabled by default. For details, see “18.2
Recommended Operating Conditions” in
“Electrical Characteristics”.
❐ The LVD function can be controlled through software.
❐ The LVD reset circuit control register (LVDCC) enables or
disables the LVD reset.
❐ The LVD reset circuit has an internal low-voltage detector.
The combination of detection voltage and release voltage
can be selected from four options.
■ Comparator  2 channels
❐ 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) simul-
taneously.
■ Flash memory security function
❐ Protects the content of the Flash memory.
