Fifteen dsPIC33 general-purpose devices have been introduced. Key features that are
specific to this family include:
MICROCHIP TECHNOLOGY’S MICROSOLUTIONS eNEWSLETTER - November 2005
Looking for higher levels of performance, memory and I/O without the complexity of traditional
Digital Signal Processors (DSPs)?
Microchip’s new dsPIC33 Digital Signal Controller dsPIC33 General Purpose DSCs
(DSC) architecture gives you a cost-effective
solution for applications requiring large memory,
I/O or substantial performance at 3.3 volts.
is fully compatible with Microchip’s universal MPLAB
Integrated Development Environment (IDE), and the
MPLAB C30 C compiler.
Microchip has expanded its line of dsPIC ? DSCs
with the introduction of the dsPIC33 family.
These devices operate at 40 MIPS, with family
members ranging from 64 to 256 Kbytes of self-
programming Flash, 8 to 30 Kbytes of RAM and
64- to 100-pin packages. The dsPIC33 features
an 8-channel DMA and some versions have two
1.1 Msps A/D converters. Additionally, the new
dsPIC33 family has the same instruction set as the dsPIC30 family and uses the same
universal MPLAB ? development tools that are common to all of Microchip’s microcontroller
families.
If you need to employ advanced algorithms in a
control environment and find that 16-bit DSPs don’t
have the ability to sustain performance required
applications, look no further. The dsPIC33 provides
DSP levels of performance and large amounts of
memory in a microcontroller-centric architecture
that is ideal for embedded control. To provide further
“The addition of 27 new dsPIC33 Flash-based DSCs to the 21 existing dsPIC30 DSCs
signals our commitment to the market,” said Sumit Mitra, vice president of Microchip’s Digital
Signal Controller Division.
Two dsPIC33 product lines are being brought to market: (1) General Purpose DSCs
and (2) Motor Control and Power Conversion DSCs
These devices share the following key features:
? 40 MIPS deterministic performance
? Serial I/O subsystems, including up to two each: SPI?, I2C?, UART and CAN
? One or two 500 ksps, 12-bit A/D converters
? Codec interface
Product Applications
? Two-way radios, hands-free kits, answering machines, speech and audio playback
applications, power-line modems, security systems and portable medical monitoring
equipment
dsPIC33 Motor Control and Power Conversion DSCs
Twelve dsPIC33 motor control and power conversion devices have been introduced. Key
features that are specific to this family include:
? One or two 1.1 Msps 10-bit A/D converters with up to 8 sample and holds for simultaneous
sampling
? Specialized PWM for motor control, lighting and power conversion applications
? Quadrature Encoder Interface
Product Applications
? Sewing machines, LED lighting arrays, washing machines, access control, online UPS,
environmental control, electronically assisted power steering, precision manufacturing
equipment, absolute encoders and resolvers, inverters and electric vehicles.
Development Tools Support and Availability
Within the MPLAB ? IDE, high-level resources are added in a microcontroller-friendly way to
allow the utilization of DSC features with minimal effort. These features include Microchip’s
Visual Device Initializer, which can generate initialization code in a few clicks, and the
motor control GUI, which can be used to quickly tune dsPIC ? DSC motor control libraries
to a specific motor type. Sophisticated libraries have been developed which fully exploit
the dsPIC DSC’s capabilities while presenting a user-friendly environment for engineers.
Many libraries are free, while others can be licensed for a low, one-time fee. One area
gaining popularity is the use of digital filters. The low-cost Digital Filter Designer and the
free dsPICworks? software can help users define filters to their specifications, simulate
performance and generate code, all without immersion in DSP theory.

Selected members of the new dsPIC33 family are available today for early-adopter sampling.
General sampling for all 27 of the dsPIC33 devices are expected to begin in Q1 2006, and
volume production is planned to start in Q2 2006.
