Description

The STM32G483xE 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

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 (4 Msps), seven comparators, six operational amplifiers,

seven DAC channels (3 external and 4 internal), an internal voltage reference buffer, a lowpower

RTC, two 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.

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 STM32G483xE devices embed an AES.

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 STM32G483xE family offers 8 packages from 48-pin to 128-pin.
