10 Freescale Semiconductor
Analog-to-digital converter (ADC):
• 16 channels, 10-bit resolution
• External conversion trigger capability
• Two 1M bit per second, CAN 2.0 A, B software compatible modules:
• Five receive and three transmit buffers
• Flexible identifier filter programmable as 2 x 32 bit, 4 x 16 bit, or 8 x 8 bit
• Four separate interrupt channels for Rx, Tx, error, and wake-up
• Low-pass filter wake-up function
• Loop-back for self test operation
Timer:
• 16-bit main counter with 7-bit prescaler
• Eight programmable input capture or output compare channels
• Two 8-bit or one 16-bit pulse accumulators
Six PWM channels:
• Programmable period and duty cycle
• 8-bit 6-channel or 16-bit 3-channel
• Separate control for each pulse width and duty cycle
• Center-aligned or left-aligned outputs
• Programmable clock select logic with a wide range of frequencies
• Fast emergency shutdown input
Serial interfaces:
• Two asynchronous serial communication interfaces (SCI)
• Synchronous serial peripheral interface (SPI)
• Inter-integrated circuit interface (IIC)
Liquid crystal display driver with variable input voltage:
• Configurable for up to 32 frontplanes and 4 backplanes or general purpose input or output
• Five modes of operation allow for different display sizes to meet application requirements
• Unused frontplane and backplane pins can be used as general purpose input or output
16 high current drivers suited for PWM motor control:
• Each PWM channel switchable between two drivers in an H-bridge configuration
• Left, right, and center aligned outputs
• Support for sine and cosine drive
•Dithering
• Output slew rate control
