STMICROELECTRONICS, ST; ST;) The latest STM32F446 series microcontroller brings more application options for designers, new products integrate enhanced ARM® Cortex®-M4 processing performance, 256KB or 512KB flashlights (all equipped 128KB RAM), high energy storage expansion interface and various communication interfaces.
New products use the unique adaptive real-time accelerator (Art AcceleratorTM, Adaptive Real-Time Accelerator) technology, intelligent system architecture, and advanced 90nm flash technology, further enhance the standard ARM Cortex for built-in floating point units and DSP instructions. -M4 core processing performance. Therefore, the CPU of STM32F446 has 225 DMIPS processing performance of leading similar products. When performing software code in 180MHz, Coremark®'s test scores have achieved a good grade for 608 points.
In addition, advanced new peripherals and multi-interface efficient synchronous communication features can achieve higher intelligence and interactive industrial, scientific research, medical, and Internet of Things applications (IoT, Internet-of-Things) applications. New peripherals include 1 camera interface, 7 I2S audio interfaces, 1 consumer electronic controller (CEC, Consumer Electronics Controller), 1 SPDIF digital audio interface, and 1 display parallel interface for managing multiple HDMI devices . The USB module of the built-in dedicated rail (Power Rail) drops the lowest kernel supply voltage to 1.7V.
In order to allow designers to use external memory seamless expansion systems, STM32F446 integrates the Flexible Memory Controller (FMC, Flexible Memory Controller) and the two four-wire SPI (QSPI) interface. The 90MHz FMC controller simplifies the control of the LCD of SRAM, SDRAM, NOR / NAND, or the LCD of the built-in controller, supports memory remapping (Memory-REMAP) mode to improve performance. Double QSPI interface can be run independently of FMC, directly connected or connected by memory mapping, support single data rate or dual data rate transmission.
Developers who have strictly limited design power consumption will benefit from the energy saving characteristics of STM32F446. Combined with dynamic voltage adjustment functions from advanced 90nm manufacturing process, the extensive clock gating circuit (Clock Gating), flexible sleep mode, STM32F446 microcontroller can reduce the working current to 50μA in stop (STOP) mode, while Keep all data information in the SRAM.
The STM32F446 will benefit designers to benefit from a wide range of STM32 development ecosystems and more than 600 pins and software compatible, based on the Microcontroller series of ARM Cortex-M kernel, including recently released STM32F7 series. The development of ecosystems include simple and easy-to-use STM32Cube open source software platforms, STM32 Nucleo expands prototype development boards and STM32 Discovery evaluation boards, support market mainstream development environments, such as IAR EWARM, Keil MDK-ARM, GCC-based integrated development environment (IDE ) Or online MbedTM.
The STM32F446 sample has begun to provide the main customers to test, which is expected to be mass production in the first quarter of 2015, including a WLCSP81 micro package with only 3.728mm x 3.85mm and 20mm x 20mm LQFP144, 256KB and 512KB (all equipped with 128kbyte SRAM) ) Two flash capacity supplies customers.
