Features

• Seven or eight PWM channels with programmable period and duty cycle

– 8-bit 4-channel or 16-bit 2-channel (80-Pin Version)

– 8-bit 8-channel or 16-bit 4-channel (112-Pin Version)

– Separate control for each pulse width and duty cycle

– Center- or left-aligned outputs

– Programmable clock select logic with a wide range of frequencies

• Serial interfaces

– Two asynchronous serial communications interfaces (SCI)

– Up to two synchronous serial peripheral interfaces (SPI)

• Byteflight

– 10 MBit/s serial protocol

• SIM (system integration module)

– CRG (windowed COP watchdog, real-time interrupt, clock monitor,

clock generation and reset)

– MEBI (multiplexed external bus interface)

– MMC (memory map and interface)

– INT (interrupt control)

– BKP (breakpoints)

– BDM (background debug mode)

• Clock generation

– Phase-locked loop clock frequency multiplier

– Limp home mode in absence of external clock

– Slow mode divider

– Low power 0.5 to 40 MHz crystal oscillator reference clock

• Operating frequency

– 50 MHz equivalent to 25 MHz bus speed for single chip

• Internal 5 V to 2.5 V regulator

• 112-Pin LQFP or 80-Pin QFP package

– I/O lines with 5-V input and drive capability

– 5-V ATD inputs

– Dual supply (5 V for I/O and ATD, 2.5 V for logic

• Development support

– Single-wire background debug™ mode (BDM)

– On-chip hardware breakpoints
