Microchip Release New dsPIC33EP128GS808 Digital Signal Controller (DSC) Family
New DSC Family offers up to 128 KB of Flash Memory with Live Update Capability
Microchip have released a new family of high-performance, live updateable dsPIC® digital signal controller (DSC).
The new dsPIC33EP128GS808 devices have up to 128 KB of dual-partition Flash memory with live update capability,
advanced analog features and enhanced Core Independent Peripherals (CIPs) suitable for high-end digital power applications
such as AC/DC power supplies, DC-DC converters, power inverters and advanced lighting applications.
These devices offer high-resolution pulse width modulators optimized for digital power applications.
In addition, the devices include advanced analog features and peripherals.
There are five separate high-speed 12-bit Analog-to-Digital Converter (ADC) modules each with 300 ns conversion latency.
Up to 22 input channels are shared across these five ADC units. There are also four analog comparators,
each with their own dedicated 12-bit reference Digital-to-Analog Converter (DAC); and two programmable gain amplifiers
to reduce external component count.
New features include a peripheral trigger generator, which is a user-programmable state machine that can respond to events
faster than a firmware-driven implementation while offloading the processor for other tasks. In addition, a four-channel Direct Memory Access (DMA)
unit is included to further increase the controller’s overall system performance.
These devices also have configurable logic cells that can be used to create combinatorial
Pulse Width Modulation (PWM) signals for advanced applications or to minimize the need for external glue logic
in the design. They also contain up to two CAN communication interfaces for automotive and industrial applications.
Select new variants in the family of dsPIC digital signal controllers are offered in an 80-pin package
giving designers increased memory and more interface pins to fulfill the requirements of more sophisticated designs.
“Design engineers are under a lot of pressure to get products to market on-time,” said Joe Thomsen,
vice president of Microchip’s MCU16 business unit. “The dsPIC33EP128GS808 family has the DSP performance,
advanced peripherals and memory options that designers need. Plus, the family is supported by Microchip’s free Digital Compensator
Design Tool (DCDT), advanced SMPS libraries, evaluation platforms and reference designs which all help customers accelerate
the overall process of designing their digital power supply.”
The dsPIC33EP128GS808 family is supported by the MPLAB® ecosystem including
MPLAB X Integrated Development Environment (IDE) and XC16 compiler.
