16-bit Microcontroller (MCU) Portfolio
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.
PIC24F: Lowest Power 16-bit MCUs
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 and low power
applications. Serial communication peripherals include up
to 4 UARTs, 3 SPI and 3 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: Highest Performance 16-bit MCUs
PIC24 devices offer up to 70 MIPS performance with
a combination of large memory and a wide variety of
package options. They also includes large Flash in smaller
packages (5 × 5 mm). The built-in peripherals include high
performance 12-bit ADC and general purpose and motor
control 16-bit PWMs. Communication peripherals include
up to 2 CAN modules, 4 UARTs (with IrDA support), 4
SPI, 2 I
2
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.
Leading 16-bit Performance and Features
16-bit Digital Signal Controller (DSC) Portfolio
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 required
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.
dsPIC33: Highest Performance 16-bit MCU
with Integrated DSP
The dsPIC33 core is designed to execute and control
the 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.
