ST has extended the STM32L4 technology providing
more performance (up to 120 MHz) ,
more embedded memory (up to 2 Mbytes of Flash memory and 640 Kbytes of SRAM) and richer graphics and connectivity features while keeping the best-in-class ultra-low-power capability.
The STM32L4+ series shatters processing capabilities limits in the
ultra-low-power world by delivering 150 DMIPS/409 CoreMark score while executing from internal Flash memory and by embedding 640 Kbytes SRAM enabling more advanced consumer, medical and industrial low-power applications and devices.
STM32L4+ microcontrollers offer
dynamic voltage scaling to balance power consumption with processing demand, low-power peripherals (LP UART, LP timers) available in Stop mode, safety and security features, smart and numerous peripherals, advanced and low-power analog peripherals such as op amps, comparators, 12-bit DACs and 16-bit ADC (hardware oversampling).
The new STM32L4+ series also embeds advanced graphic features enabling state-of-the-art graphic user interfaces.
The
Chrom-ART Accelerator™, ST's proprietary 2D hardware graphic accelerator, efficiently handles repetitive graphic operations releasing the main CPU capabilities for real time processing or even more advanced graphic operations.
The Chrom-ART Accelerator is coupled with the large embedded SRAM, the Chrom-GRC™ round display memory optimizer, the high-throughput Octo-SPI interface and to the advanced TFT and DSI controllers, allowing you to achieve ‘smartphone-like’ graphic user interfaces in a single-chip and an ultra-low power solution.
The STM32L4+ series are available in different lines: STM32L4R5/S5, STM32L4R7/S7 (with TFT interface) and STM32L4R9/S9 (with MIPI-DSI and with TFT interface).
To simplify migration and give you all the flexibility you need, the
STM32L4+ is pin-to-pin compatible with the different STM32 series and opens the door to the full STM32 ecosystem.
