STM32H503 High-Efficiency MCU Series
STMicroelectronics' STM32 MCUs offer enhanced performance and power efficiency
STMicroelectronics' STM32H503 microcontrollers extend the STM32 high-performance portfolio and offer enhanced performance and power efficiency with 128 KB of Flash, 32 KB of RAM, and 25-pin to 64-pin packages in WLCSP and LQFP profiles, as well as the UFQFPN package. The line contains the Arm® Cortex®-M33 with DSP and floating‐point unit (FPU) running up to 250 MHz.
Features
- High performance: at 250 MHz, the STM32H503 delivers 375 DMIPS/1023 CoreMark performance executing from Flash memory, with 0-wait states using ST's ART Accelerator™
- Embedded peripherals: up to 13 communication peripherals including I³C, FD-CAN and USB 2.0 full-speed host and device
- Power efficiency:
- 86 µ/MHz typical at VDD= 3.3 V and +25°C in run mode (peripherals off)
- 54 µA typical in stop mode (low-power mode)
- 3.5 µA typical in standby mode (low-power mode)
- 380 nA typical in VBAT mode with RTC (low-power mode)
Applications
- Industrial: programmable logic controllers (PLC), industrial motor controls, pumps, and compressors
- Smart homes: air conditioners, refrigerators and freezers, central alarms, systems, and washing machines
- Personal electronics: keyboards, smartphones, IoT tags, and tracking devices
- Smart cities: industrial communication, lighting controls, and digital power
- Medical and healthcare: CPAPs and respirators, dialysis machines, pill distributors, and powered patient beds
