Digital Signal Controllers
Microchip Technology, Inc., has announced a new family of dsPIC33 Digital Signal Controllers (DSCs):
the dsPIC33EP512GM710 family. This is an expansion of
Microchip’s dsPIC DSC portfolio that adds higher levels of
integration for motor control applications.
The new family of DSCs enables efficient dual motor
control with 12 motor control PWM channels (six pairs),
dual 12-bit ADCs, multiple 32-bit quadrature encoder
interfaces, and two CAN modules. With this level of
integration, the dsPIC33EP512GM710 family can
independently control two motors with a single
microcontroller for optimized system costs. This family can
also serve as a communication hub for automotive or
industrial applications to connect with multiple CAN busses.
This family
expands the existing
dsPIC33EP families by
supporting 512 KB
Flash, 48 KB RAM,
and four operational
amplifiers (op-amps).
Other features of
this family include
enhanced analog
functionality with
two independent
ADC modules,
configurable as 10-
bit 1.1 Msps with four
sample and holds or 12-bit 500 ksps with one sample and
hold, supporting up to 49 channels. This analog integration
enables advanced sensor applications that require multiple
precision ADCs with several sample and holds, as well as
the processing power of a DSP. The family also includes a
Peripheral Trigger Generator (PTG) for scheduling complex
high speed peripheral operations which saves software
cycles and reduces firmware complexity.
The new dsPIC33EP512GM710 MCU family is available
for sampling and volume production, starting at $2.63 each
in volume.
Motor Gate Driver
Also from Microchip Technology, Inc., is a new three- phase BLDC motor gate driver with power module: the
MCP8024. This new device includes functions that power
dsPIC DSCs and PICs with capabilities to drive six N-channel
MOSFETs. Customers can implement improved performance
and high robustness, providing increased efficiency and
lowering system cost while reducing time to market.
The MCP8024 operates across a wide voltage range of
6V to 28V, and can withstand transient voltage up to 48V.
The device provides high-integration analog such as three
current-sensing operational amplifiers, an over-current
comparator, MOSFET drivers, and a bidirectional
communication interface for a complete motor system
design.
The configurable driver dead-time management, driver
blanking-time control, and Over-Current Limit (OCL) for
external MOSFETs offer a significant increase in flexibility.
The adjustable step-down DC-to-DC converter powers a
broad range of microcontrollers, with the efficiency benefits
of a switch-mode power supply. Additionally, the wide
operating temperature range from - 40°C to +150°C
(H-temp) allows the MCP8024 to be utilized in harsh
environments.
The MCP8024 is available in thermally enhanced
40-pin QFN 5 mm x 5 mm and 48-pin TQFP 7 mm x 7 mm
packages. The MCP8024 is well suited for a broad range of
applications including fans, motion control, and robotics,
among others.
The MCP8024 is available now for $2.61 each in
volume.

Easy to Assemble
Prototyping Boards
Adding to their existing line of prototyping and evelopment boards, Mikronauts has launched the
"Easy to Assemble" (EZas) series of prototyping boards.
All boards in the EZas line are silk-screened on both
sides such that power and signal buses are highlighted,
taking the guesswork out of finding the signals under the
solder mask. EZas boards are designed to minimize the
