STMicroelectronics STM32F723IEK6

Overview

STM32F723IEK6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, operating at up to 216 MHz (462 DMIPS), featuring 512 KB Flash, 256+16+4 KB SRAM, dual USB OTG (HS/FS), three 12-bit ADCs (2.4 MSPS), and 21 communication interfaces including CAN 2.0B, SAI, and SDMMC - deployed in industrial HMI, motor control gateways, and audio-enabled edge nodes.

For engineers reviewing the STM32F723IEK6 datasheet, STM32F723IEK6 pinout, STM32F723IEK6 application, or STM32F723IEK6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual USB OTG PHY support (HS + FS), 140 GPIOs with 5 V tolerance, and integrated audio peripherals (SAI, audio PLLs) for real-time signal processing in resource-constrained embedded systems.

Technical Context

The STM32F723IEK6 implements an adaptive real-time accelerator (ART Accelerator) with 8 KB instruction and 8 KB data caches, enabling zero-wait-state execution from Flash and external memories. Its memory subsystem includes 256 KB data TCM RAM, 16 KB instruction TCM RAM, and 4 KB backup SRAM retained in Standby mode.

It integrates dual USB OTG controllers: one full-speed with on-chip PHY, and one high-speed/full-speed with dedicated DMA and dual on-chip PHYs (FS + HS). The device supports true hardware audio timing via two independent audio PLLs (PLLI2S and PLLSAI) and dual Serial Audio Interfaces (SAIs) compliant with I²S, PCM, and AC'97 protocols.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F723IEK6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and L1 cache (8 KB instruction + 8 KB data). This configuration enables zero-wait-state execution from Flash memory, verified per DS11853 Rev 9 Section 3.1. The internal voltage regulator and VCAP decoupling capacitors must meet specified tolerances to sustain this frequency under full load.

Does STM32F723IEK6 support USB High-Speed device mode without external components?

Yes - the part integrates a full-speed PHY and a dedicated high-speed PHY on-die, allowing native USB 2.0 High-Speed (480 Mbps) device operation without external transceivers. This is confirmed in DS11853 Rev 9 Section 3.30 and Table 2, distinguishing it from F722 variants that lack the on-chip HS PHY.

How many ADC channels can be used simultaneously in triple interleaved mode?

In triple interleaved mode, all 24 ADC channels (across three 12-bit ADCs) can be sampled concurrently at up to 7.2 MSPS aggregate rate. Each ADC handles eight channels, with hardware synchronization ensuring sub-100 ns skew - detailed in DS11853 Rev 9 Section 3.33 and Table 2.

What package and pin count does STM32F723IEK6 use, and is it pin-compatible with other F723 variants?

STM32F723IEK6 uses the LQFP64 package (10 × 10 mm, 0.5 mm pitch) with 64 pins. It shares identical pinout and electrical characteristics with other STM32F723xx LQFP64 variants (e.g., STM32F723ICT6), enabling direct substitution within the same package footprint per DS11853 Rev 9 Section 7.1 and Table 10.
