Product details

The STM32F733IEK6 is an STMicroelectronics STM32F7-series MCU built around a single ARM Cortex-M7 core running at 216 MHz. The 138 available I/O and the connectivity set — CANbus, EBI/EMI, I²C, SAI, QSPI, USB, and multiple UART/USART — cover the typical peripheral mix for a mid-complexity embedded controller.

Industrial temperature range — deployment context

The internal oscillator and the brown-out detect / POR / WDT peripherals reduce external component count in cost-sensitive designs.

STMicroelectronics lists the STM32F733IEK6 as Active.

Frequently asked questions

Can the STM32F733IEK6 drop onto the same PCB land pattern as the STM32F730VET6?

No — the STM32F733IEK6 uses a 201-UFBGA (10×10mm) package with 138 I/O, which is a different footprint class from the LQFP variants in the STM32F730 series. Layout respin is required; footprint compatibility cannot be assumed.

Does the STM32F733IEK6 have an on-chip Ethernet MAC, or does it need an external PHY?

No integrated Ethernet MAC is listed in the connectivity block. A Profinet/EtherNet/IP gateway panel built around this MCU requires an external Ethernet PHY — the part does not carry a hardware IP stack for industrial Ethernet protocols.
