32-bit RISC Microcontroller

Fujitsu 

MB91F109

(Continued)

16-bit reload 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 × 4 (INT0 to INT3)

• Internal interrupt incident:UART, DMA controller (DMAC), 10-bit A/D converter, 16-bit reload-timer, PWM timer,

U-TIMER and delayed interrupt module

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

Others

• Reset cause: Power-on reset/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.)

• Packages: LQFP-100 and QFP-100

• CMOS technology (0.5 µm)

• Power supply voltage: 3.15 V ∼ 3.6 V
