Are costs, performance, low power and smaller packages 

important considerations for your next design?
PIC24 MCUs offer a variety of peripherals, memory sizes 

and packaging choices. The 16 MIPS PIC24F family is 

designed for low-power applications. The 40/70 MIPS 

PIC24H/E MCUs are designed for high-performance 

applications. Both families have the same instruction 

set, share basic peripherals, have common pinouts and 

use the same tools for development. The PIC24 families 

are compatible with dsPIC DSCs for easy migration when 

additional performance or DSP capability is required.

With 16 MIPS performance and an extensive peripheral 

set including a graphics controller, USB Device/Embedded 

Host/OTG and capacitive touch sense interface, the 

PIC24F MCUs are cost-effective for low-power applications. 

Serial communication peripherals include up to four 

UARTs, three SPI and three I

2

C™. With the introduction 

of XLP Technology, select PIC24F devices have industry-

leading low-power performance with sleep numbers as low 

as 10 nA and RTCC operation down to 400 nA.

PIC24E devices offer up to 70 MIPS performance with 

a combination of large memory and a wide variety of 

package options. They also include large Flash in smaller 

packages (5 × 5 mm). The built-in peripherals include a 

high-performance 12-bit ADC and general purpose and 

motor control 16-bit PWMs. Communication peripherals 

include up to two CAN modules, four UARTs (with IrDA 

support), four SPI, two I

C and USB Device/Embedded 

Host/OTG. High-performance 16 channel Direct Memory 

Access (DMA) provides better data handling capability 

optimizing CPU throughput. AEC-Q100-qualified extended 

(125°C) and high-temperature (150°C) options for 

industrial and automotive applications are available. 

Does your embedded control application demand performance 

for advanced motor control, digital power, speech and audio 

processing? Do you want to implement digital filters and FFT 

algorithms for signal analysis?
dsPIC DSCs offer innovative peripherals and the necessary 

performance to meet these needs. Our dsPIC family is a 

100% PIC MCU with enhanced math capabilities. dsPIC 

DSCs blend the performance of DSP with the simplicity of 

an MCU.

The dsPIC33 core is designed to execute and control high-

speed precision digital control loops and digital processing 

up to 70 MIPS. The optimized motor control and digital 

power conversion peripherals include the highest 

performance ADC, PWMs, and analog comparators. A wide 

variety of memory and package options, communication 

peripherals, 15 channel DMA and general purpose 

peripherals provide flexibility to your high-performance 

embedded control designs. AEC-Q100-qualified extended- 

and high-temperature options for industrial and automotive 

applications are available.
