The STM32G491xC/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 (up to 512 Kbytes of flash memory, and 112 Kbytes of SRAM), a Quad-SPI flash memory interface, 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 three fast 12-bit ADCs (4 Msps), four comparators, four four DAC channels (two external and two internal), an internal voltage reference buffer, a low-power RTC, one general-purpose 32-bit timer, three 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer.

They also feature standard and advanced communication interfaces such as:

- Three I2Cs

- Three SPIs multiplexed with two half duplex I2Ss

- Three USARTs, two UARTs and one low-power UART.

Two 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 V_BAT input allows backup of the RTC and the registers.

The STM32G491xC/xE family offers 9 packages from 32-pin to 100-pin.
