Introduction
The
Discovery kit is a digital power solution and a complete demonstration and development platform for the
STMicroelectronics Arm
®
Cortex
®
-M4 core-based STM32G474RET6 microcontroller. Leveraging the new HRTimer-oriented
features, 96 Kbytes of embedded RAM, math accelerator functions, and USB PD3.0 offered by STM32G474RET6, the B-
G474E-DPOW1 Discovery kit helps the user to prototype applications with digital power such as a buck-boost converter, RGB
power LED lighting, or a class-D audio amplifier, based on the USB Type-C
®
2.0 FS connector interface. The B-G474E-DPOW1
Discovery kit does not require any separate probe as it integrates the STLINK-V3E debugger and programmer.
The STM32G474RET6 microcontroller features FMAC and CORDIC mathematical hardware accelerator, five 12-bits ADCs
(5 MSPS) up to 42 channels and with resolution up to 16-bit with hardware oversampling, seven 12-bit DAC channels, seven
ultra-fast rail-to-rail analog comparators, six operational amplifiers with PGA mode, seventeen timers with various advanced
functionalities, four I
2
C fast-mode plus, five USARTs, one LPUART, four SPIs, one SAI, three CAN
‑
FD controllers, one USB 2.0
full-speed interface and a UCPD block allowing connection to USB Type-C
®
compatible with USB Power Delivery, a true
random number generator, one FMC parallel synchronous interface, a quad-SPI memory interface, SWD and JTAG debugging
support.
This Discovery kit offers everything required for users to start and develop applications. The hardware features on the board
help to evaluate the following peripherals: USB Type-C
®
compatible with USB PD3.0, HRTimer evaluation, digital power for
buck-boost application with Class-D audio amplifier and RGB power LED lighting. Thanks to its two 32-pin 2.54 mm pitch
extension connectors, it also enables users to plug it on a breadboard for prototyping. The integrated STLINK-V3E provides an
embedded in-circuit debugger and programmer for the STM32 MCU.
The B-G474E-DPOW1 Discovery kit comes with the STM32 comprehensive free software libraries and examples available with
the STM32Cube package.
