10-bit A/D converter (successive approximation conversion type)

• 10-bit resolution, 4 channels

• Successive approximation type: Conversion time of 5.6 µs at 25 MHz

• Internal sample and hold circuit

• Conversion mode: Single conversion/scanning conversion/repeated conversion selective

• Start: Software/external trigger/internal timer selective

16-bit reload timer

• 16-bit timer: 3 channels

• Internal clock: 2 clock cycle resolution, divide by 2/8/32 selective

Other interval timers

• 16-bit timer: 3 channels (U-TIMER)

• PWM timer: 4 channels

• Watchdog timer: 1 channel

Bit search module

First bit transition “1” or “0” from MSB can be detected in 1 cycle

Interrupt controller

• External interrupt input: Non-maskable interrupt (NMI), normal interrupt 8 (INT0 to INT7)

• Internal interrupt incident:UART, DMA controller (DMAC), A/D converter, U-TIMER and delayed interrupt

module

• Priority levels of interrupts are programmable except for non-maskable interrupt (in 16 levels)

Others

• Reset cause: Power-on reset/hardware standby/watchdog timer/software reset/external reset

• Low-power consumption mode: Sleep mode/stop mode

• Clock control

Gear function:Operating clocks for CPU and peripherals are independently selective

Gear clock can be selected from 1/1, 1/2, 1/4 and 1/8 (or 1/2, 1/4, 1/8 and 1/16)

However, operating frequency for peripherals is less than 25 MHz.

MB91107 (0.25 µm) ••••• Production model

MB91108 (0.25 µm) ••••• Production model

• Power supply voltage: 3.3 V ± 0.3 V (internal regulator)
