Features

Six Direct Memory Access (DMA) Controllers

Three 16-bit dual PWMs provide six PWM outputs

Vectored Interrupt (VI) Capability - Faster interrupt response time
• Selectable high/low priority
• Fixed interrupt latency of three instruction cycles
• Programmable vector table base address
• Backwards compatible with previous interrupt capabilities

Memory Access Partition (MAP): The Program Flash Memory can be partitioned into:
• Application Block
• Boot Block
• Storage Area Flash (SAF) Block

Device Information Area (DIA) Stores:
• Temperature Indicator factory calibrated data
• Fixed Voltage Reference measurement data
• Microchip Unique Identifier

Low Power Mode Features:
• Sleep: < 1μA typical @ 3V
• Doze: CPU and Peripherals Running at Different Cycle Rates (typically CPU is lower)
• Idle: CPU Halted While Peripherals Operate
• Sleep: Lowest Power Consumption

Peripheral Module Disable (PMD):
• Ability to selectively disable hardware module to minimize active power consumption of unused
• peripherals

Peripheral Pin Select (PPS):
• Enables pin mapping of digital I/O

Analog-to-Digital Converter with Computation (ADCC):
• Up to 43 external channels
• Automated math functions on input signals such as averaging, filter calculations, oversampling and threshold comparison
• Operates in Sleep
• Five internal analog channels

Hardware Capacitive Voltage Divider (CVD) Support:
• Automates touch sampling and reduces software size and CPU usage
• Four external inputs

8-Bit Digital-to-Analog Converter (DAC):
• Buffered output available on two I/O pins
• Internal connections to ADC and Comparators

Two Comparators (CMP):
• Configurable output polarity
• External output via Peripheral Pin Select

Zero-Cross Detect (ZCD):
• Detect when AC signal on pin crosses ground

Voltage Reference:
• Fixed Voltage Reference with 1.024V, 2.048V and 4.096V output levels
• Internal connections to ADC, Comparator and DAC

5 x UART - One UART supports LIN/DMX/DALI
• DMA compatible
• Asynchronous UART, RS-232, RS-485 compatible
• Programmable 1, 1.5, 2 stop bits

Two SPI modules:
• Configurable length bytes
• Arbitrary length data packets
• Transmit-without-Receive and Receive-without-transmit option
• Transfer byte counter
• Separate transmit and receive buffers with 2-byte FIFO and DMA capabilities

One I2C module, SMBus, PMBus™ Compatible:
• 7-bit and 10-bit addressing modes with address masking modes
• Dedicated address, transmit and receive buffers and DMA capabilities
• I2C, SMBus 2.0 and SMBus 3.0, and 1.8V input level selections
• Multi-Master mode, including self-addressing

Programming/Debugging Features
