ST STM32G0C1E-EV Bedienungsanleitung

Introduction

The STM32G0C1E-EV Evaluation board is a high-end development platform for the STM32G0C1VET6 microcontroller

operating at up to 64 MHz frequency with internal 512-Kbyte Flash memory, 144-Kbyte RAM, USB 2.0 FS device and host,

two CAN FDs, USB Type-C®, and Power Delivery controller interfaces (UCPD) compliant with USB Type-C® r1.2 and USB

PD specification r3.0, three I2Cs, three SPIs, six USARTs, two low-power UARTs, one 12-bit ADC, two 12-bit DACs, three

general-purpose comparators, seven general-purpose timers, two low-power timers, HDMI CEC, and SWD debugging support.

The full range of hardware features on the STM32G0C1E-EV Evaluation board includes the mother board, the legacy peripheral

daughterboard, and the USB-C® and Power Delivery daughterboard, which help to develop applications, and evaluate all

peripherals, such as USB Type-C® connector with USB PD, motor control connector, CAN FD, USB 2.0 FS, RS-232, RS-485,

audio DAC, microphone ADC, TFT LCD, IrDA, IR LED, IR receiver, LDR, microSD™ card, CEC on two HDMI connectors,

Smartcard slot, RF EEPROM, and temperature sensor.

The board integrates an ST-LINK/V2-1 as an embedded in-circuit debugger and programmer for the STM32 MCU.

The daughterboard and extension connectors provide an easy way to connect a daughterboard or wrapping board for the user's

specific application.

The USB-C® and Power Delivery daughterboard features two independent USB-C® ports controlled by STM32G0. USB-C® port

1 is a dual role power (DRP) port and can provide up to 45 W of power. USB-C® port 2 is a sink port only. Both support the USB

PD protocol and the alternate mode functionality.

Application firmware examples are provided to evaluate USB-C® technology through various use cases.

5Delivery recommendations

Some verifications are needed before using the board for the first time to make sure that nothing was damaged

during shipment and that no components are unplugged or lost. When the board is extracted from its plastic

bag, check that no component remains in the bag. Before starting the demo, take the microSD™ card from the

separated ESD bag and plug it in the CN11 connector, on the right side of the board.

Warning:

There is an explosion risk if the battery is replaced with an incorrect one. Make sure to dispose of

used batteries according to the instructions.
