MCF52110 Family Configurations

• Fast analog-to-digital converter (ADC)

— Eight analog input channels

— 12-bit resolution

— Minimum 1.125 μs conversion time

— Simultaneous sampling of two channels for motor control applications

— Single-scan or continuous operation

— Optional interrupts on conversion complete, zero crossing (sign change), or under/over low/high limit

— Unused analog channels can be used as digital I/O

• Four 32-bit timers with DMA support

— 12.5 ns resolution at 80 MHz

— Programmable sources for clock input, including an external clock option

— Programmable prescaler

— Input capture capability with programmable trigger edge on input pin

— Output compare with programmable mode for the output pin

— Free run and restart modes

— Maskable interrupts on input capture or output compare

— DMA trigger capability on input capture or output compare

• Four-channel general purpose timer

— 16-bit architecture

— Programmable prescaler

— Output pulse-widths variable from microseconds to seconds

— Single 16-bit input pulse accumulator

— Toggle-on-overflow feature for pulse-width modulator (PWM) generation

— One dual-mode pulse accumulation channel

• Pulse-width modulation timer

— Support for PCM mode (resulting in superior signal quality compared to conventional PWM)

— Operates as eight channels with 8-bit resolution or four channels with 16-bit resolution

— Programmable period and duty cycle

— Programmable enable/disable for each channel

— Software selectable polarity for each channel

— Period and duty cycle are double buffered. Change takes effect when the end of the current period is reached

(PWM counter reaches zero) or when the channel is disabled.

— Programmable center or left aligned outputs on individual channels

— Four clock sources (A, B, SA, and SB) provide for a wide range of frequencies

— Emergency shutdown

• Two periodic interrupt timers (PITs)

— 16-bit counter

— Selectable as free running or count down

• Real-Time Clock (RTC)

— Maintains system time-of-day clock

— Provides stopwatch and alarm interrupt functions

• Software watchdog timer

— 32-bit counter

— Low-power mode support

• Backup watchdog timer (BWT)
