The two new microcontroller product lines for STMicroelectric microcontroller products improve the energy efficiency, functional integration and design flexibility of STM32F4 basic product lines, meet the technical needs of high performance embedded design. These STM32 latest microcontrollers have a working temperature of up to 125 ° C [1], and the mainly running sensor and universal industrial equipment provide a robust and reliable and high-cost system upgrade scheme for STM32F1 applications [2].
STM32F413 and encrypted function enhancements STM32F423 integrate the highest 1.5MB flash memory and 320KB SRAM, these two products are configured in the STM32F4 basic product line, and their rich audio features include serial audio interfaces (SAI), enhanced voice Collection Interface Integrated Multi-channel Digital Sigma-Delta Modulation Filter (DFSDM), which enables low power sound positioning and beamforming. New products also integrate a rich peripheral interface, including two 12-digit die converters (DACs), up to 10 UART interfaces and 3 CAN 2.0b Active interfaces. Encryption Enhancements STM32F423 also adds a hardware random number generator (TRNG) and AES-256 algorithm hardware accelerator.
As the high-end product of the STM32F4 basic product line, the new microcontroller introduces 100MHz dual-mode four-wire SPI external memory serial interface and 16-bit flexible storage controller (FMC) connected to the external SRAM, PSRAM or NOR flash, and the highest 16 Bit QVGA or 8-bit WQVGA LCD interface and USB OTG interface. Where USB OTG built-in link circuit management (LPM) and dual voltage rail saves external level conversion devices.
In addition, both product lines add RAM access mechanisms, connect RAM1 (256KB) and RAM2 (64KB), two independent memory, thus transfers the resource conflict risk by directive data bus (I / D) and system bus (SBUS). To the lowest. The new DMA data batch mode (BAM +) uses RAM1 and RAM2 two independent memory regions to process instructions and data, and the processing efficiency is extremely high, especially suitable for sensor controller related applications.
High processing performance combined with the leading energy efficiency, STM32 microcontroller integrates 100MHz 125DMIPS / 339 EEMBC® Coremark® ARM® Cortex®-M4 processor core with the descendant Dynamic Efficiency energy-saving technology, the working current is significantly reduced, only 112μA / MHZ. Dynamic Efficiency Energy Saving Technology includes the St Art AcceleratorTM Adaptive Real-Time (ART) accelerator and 1.7V lowest supply voltage, and the ART enables flash code to perform unwalaled, and the lowest supply voltage allows always connected devices to maximize battery life. Time.
