Microchip Brings Enhanced Code Protection and up to 15W of Power Delivery to its USB Microcontroller Portfolio
09 April 2024 - 2:12PM
The well-known advantages of a Universal Serial Bus (USB)
interface for embedded designs include its compatibility with
various devices, streamlined communication protocol, in-field
updatability and power delivery capabilities. To help easily
incorporate this functionality into embedded systems, Microchip
Technology
(Nasdaq: MCHP) has launched the
AVR® DU family of microcontrollers (MCUs). As the
next generation of Microchip 8-bit MCUs to integrate USB
connectivity, the AVR DU family is designed to provide enhanced
security features and higher power delivery than previous
iterations.
“USB is the standard communication protocol and power delivery
method for electronic devices,” said Greg Robinson, corporate vice
president of Microchip’s 8-bit MCU business unit. “Microchip’s AVR
DU family combines the flexibility of our most advanced 8-bit MCUs
with the versatility of enhanced power delivery to bring the
benefits of USB to a wider range of embedded systems.”
AVR DU MCUs support power delivery of up to 15W from the USB
interface, a capability not commonly found in other USB
microcontrollers within its class. This feature enables USB-C®
charging with currents up to 3A at 5V, making these MCUs an
excellent choice for devices like portable power banks and
rechargeable toys.
To strengthen its defense against malicious attacks, the AVR DU
family incorporates Microchip’s Program and Debug Interface Disable
(PDID) feature. When enabled, the enhanced code protection is
designed to lock out access to the programming/debugging interface
and block unauthorized attempts to read, modify or erase firmware.
To enable secure firmware updates, the AVR DU family employs
Read-While-Write (RWW) Flash and, when combined with a secure
bootloader, designers can use the USB interface for patching bugs,
addressing security concerns and adding new features without
disrupting product operation. This updated functionality in the AVR
DU MCUs is designed to allow for uninterrupted, in-field updates to
help extend the lifetime value of products.
Additionally, the AVR DU family helps reduce overall design and
Bill of Material (BOM) costs through a USB clock recovery feature,
which eliminates the need for a costly external crystal. Core
Independent Peripherals (CIPs) enable designers to incorporate main
device functions and system management tasks onto a compact,
single-chip solution, saving board space and reducing design
effort.
Developers of a wide range of embedded designs, from fitness
wearables and home appliances to agricultural and industrial
applications, can benefit from incorporating the highly efficient
AVR DU MCUs into their designs. A virtual demonstration of the AVR
DU family is available at try.microchip.com.
Development ToolsMPLAB® Code Configurator (MCC)
contains a software stack that supports hardware features for the
AVR DU MCU’s USB module. Fully integrated into the MPLAB
development tools system, the production-ready USB software stack
is easily configured by MCC Melody, easing the development process
and reducing time to market. To further enable rapid prototyping
and development, a Curiosity Nano Development Board (EV59F82A),
MPLAB X Integrated Development Environment (IDE) and MPLAB XC8
Compiler are also available to support the AVR DU family.
