New entry-level product featuring expanded memory and additional features

STMicroelectronics (hereinafter ST) has launched the new entry-level STM32F412, featuring expanded memory and additional functions, and the STM32F410, which is the first to be certified at 125°C. The Quick Start Discovery Kit has also been enhanced to allow users to take advantage of these new features.

With these new products, the range of options for the Access Lines has been further expanded. The Access Lines are an affordable product line featuring ARM® Cortex®-M4 cores at 84 MHz (STM32F401 line) and 100 MHz (STM32F410/F411/F412 line), flash memory ranging from 128 KB to 1 MB, and RAM up to 256 KB, and are included in the high-performance microcontroller STM32F4 series. It is also easy to expand with other Foundation Line [1] and Advanced Line [2] devices that make up this series.

The STM32F412 provides a high-performance interface for off-chip memory via dual-mode 100MHz Quad-SPI and a Flexible Memory Controller (FMC) for static memory that helps efficiently expand integrated 1MB Flash and 256KB RAM. It also features a new LCD parallel interface, enabling display management up to QVGA resolution with 16-bit color depth or WQVGA with 8-bit color depth.

TRNG (True Random Number Generator) further enhances the performance of security algorithms such as cryptography. In addition, the USB OTG ports currently supported on the access line have been enhanced with dual power rails and Link Power Management (LPM), allowing for increased board space without a level shifter during design.

The STM32F410 is the first result of a plan to ultimately ensure that all MCUs in the STM32F4 access line are 125°C certified. Like other access line MCUs, both the STM32F410 and STM32F412 support Direct Memory Access (DMA) Batch Acquisition Mode (BAM) to capture data without CPU intervention for power-sensitive applications. Additionally, they enable low power consumption and low CPU load through digital filters for four low-power microphone channels, allowing for the efficient hosting of speech recognition algorithms.

In addition to the innovations in these access line MCUs, ST has also added new features to the STM32F412 Discovery Kit for customers seeking continuous innovation. It features a new 1.54-inch touchscreen color LCD to simplify HMI development, as well as an onboard stereo digital MEMS microphone, an I2S codec, headphone, microphone, and speaker connections, and an Arduino™ Uno expansion connector. The cost-effective STM32 Nucleo-F412G board, equipped with the 144-pin STM32F412ZG MCU, is also available for purchase.

The STM32F412 is currently available for purchase at a price of $3.60 per unit for orders of 10,000 units and is supplied in a UQFN48 package. Additionally, the STM32F410, which operates at 85°C, is available for immediate purchase in a WLCSP package for $1.71 for orders of 10,000 units.
