The new MCU of STMicroelectronics is mainly used in electric vehicles, digital power supplies, motor control, lighting and building automation.
The new Series STM32G4 MCU can respond to the challenge of the new generation of intelligent electronic products based on sensor drive functions, and based on new energy-saving silicon carbide and gallium nitride power technology.
There are also 12 independent channels, the resolution is 184 ps, which can compensate for a flash memory of 512K bytes, with error code correction (ECC)
ARM Cortex-M4 core
Members of the STM32G4 series are based on the solid foundation of the STM32F3 series. According to STMicro about MCU's press release, Ricardo de Sa Earp, general manager of the company's microcontroller business, said new series "The rich enhancement peripherals and interfaces are integrated with industry standard ARM core."
The MCU Series is based on the ARM Cortex-M4 core, especially the high speed implementation of the kernel (170MHz).
Member equipment has hardware-based mathematics accelerators to improve performance and efficiency. Most importantly, the energy 单 unit uses more than 165μA / MHz in operation mode.
Reduce core processor burden
Integrated additional features include filter mathematical accelerator (FMAC) and dedicated CORDIC (coordinate rotation digital computer) engine. They can achieve faster results:
Rotation and vector triangular calculation for motor control
Logarithm, hyperbolic and index functions
Filter signal conditioning and digital power control
These new features are based on existing Art Accelerator, which enhance dynamic and static memory cache performance, and CCM-SRAM ROUTINE BOOSTER, improve performance and efficacy.
These hardware-based mechanisms can get results more quickly and effectively compared to the main processor. This uninstallation also releases the core to receive and process more sensor data and control other user functions.
Hardware-based network security
Today, network security is in everyone's mind, these MCUs are designed to enable developers to build it into their product's greatest content. Although the MCU is equipped with real-time firmware update of the industry standard, ST strives to "reduce threat surface" by effectively locking debugging access after initial programming. In addition, these devices use AES-256 encryption and have secure storage areas for the firmware upgrade and storage.
Analog external
StMicro is launching new MCUs applicable to "simulated enrichment applications - this term may refer to the simulation more popular than the number.
Various members of the STM32G4 series supports up to 25 simulated external settings, including:
Up to 5 12-bit 4M Sampling / Second Mode Avantimetric Converter (ADC), with hardware over-sampling functions, 16-bit resolution can be implemented.
Up to 6 high speeds, high gain bandwidth ship calculation amplifiers, built-in gain is 1%
Up to 7 12 digits 15 Msample / Sec Dac
Additional features
Run mode power: less than 165μA / MHz
On-chip RAM: with parity bit, up to 128kByte
Memory: up to 512K bytes flash, with error code correction (ECC)
Evaluation board and kit
STM32G4 has Nucleo board:
Nucleo-G474RE
Nucleo-G431RB
Fully full evaluation board:
STM32G474E-EVAL
STM32G484E-EVAL
Entire industry
There are many manufacturers in this field, and each manufacturer has some different tendencies, so, as always, the designer must select which device provides the most relevant functionality for their own applications. This is two examples:
Maxim Integrated provides MAX32591. It includes embedded security that hides sensitive data in multi-layer physical security, providing the safest key storage. It is designed for devices such as portable EFT-POS terminals that support multimedia.
The MSP430F1611 of Texas Instruments (TI) is a 16-bit ultra-low power MCU with 48KB flash, 10240b RAM, 12-bit ADC, Dual DAC, and two USART.
