dsPIC30F
9.0
The Digital Signal Controller (DSC) family of 16-bit
MCU devices provides the integrated functionality of
many
include:
• Analog-to-Digital Converters:
• General Purpose 16-bit timers
• Motor Control PWM module
• Quadrature Encoder module
• Input Capture module
• Output Compare/PWM module
• Data Converter Interface
• Serial Peripheral Interface (SPI
• UART module
• I
• Controller Area Network (CAN) module
• I/O pins
9.1
The Analog-to-Digital (A/D) Converters provide up to
16 analog inputs with both single-ended and differential
inputs. These modules offer on-board sample and hold
circuitry.
To minimize control loop errors due to finite update
times (conversion plus computations), a high-speed
low-latency ADC is required.
In addition, several hardware features have been
included in the peripheral interface to improve real-time
performance in a typical DSP-based application.
• Result alignment options
• Automated sampling
• Automated channel scanning
• Dual Port data buffer
• External conversion start control
There are two versions of A/D converters available for
the dsPIC30F family of devices:
• 10-bit high-speed A/D module
• 12-bit high-resolution A/D module
