| The STM32G474xB/xC/xE devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 170 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security. These devices embed high-speed memories (512 Kbytes of Flash memory, and 128 Kbytes of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad SPI Flash memory interface, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. The devices also embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, securable memory area and proprietary code readout protection. The devices embed peripherals allowing mathematical/arithmetic function acceleration (CORDIC for trigonometric functions and FMAC unit for filter functions). They offer five fast 12-bit ADCs (5 Msps), seven comparators, six operational amplifiers, seven DAC channels (3 external and 4 internal), an internal voltage reference buffer, a lowpower RTC, twothree general-purpose 32-bit timers, three 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer, and high resolution timer with 184 ps resolution. They also feature standard and advanced communication interfaces such as: • Four I2Cs • Four SPIs multiplexed with two half duplex I2Ss • Three USARTs, two UARTs and one low-power UART. • Three FDCANs • One SAI • USB device • UCPD The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications. Some independent power supplies are supported including an analog independent supply input for ADC, DAC, OPAMPs and comparators. A VBAT input allows backup of the RTC and the registers. The STM32G474xB/xC/xE family offers 8 packages from 48-pin to 128-pin Meer informatie: | | Family Name: | STM32G4 | Package Type: | UFQFPN | Mounting Type: | Surface Mount | Pin Count: | 48 | Device Core: | ARM Cortex M4 | Data Bus Width: | 32bit | Program Memory Size: | 512 kB | Maximum Frequency: | 170MHz | RAM Size: | 128 kB | USB Channels: | 1 | Number of SPI Channels: | 3 | Number of CAN Channels: | 3 | Number of I2C Channels: | 4 | Number of USART Channels: | 3 | Typical Operating Supply Voltage: | 1.71 → 3.6 V |
