Product details

Entry-level Cortex-M0 for industrial control

The 8 KB SRAM is organized as 8K x 8, adequate for a modest RTOS heap and a few communication buffers. If your application requires over-the-air firmware updates with a fallback image, the 64 KB Flash may be tight — plan the memory map early.

55 I/O and peripheral set

The 64-LQFP package brings out 55 I/O pins, enough to interface with a keypad, a small TFT display, and several sensors without needing an external GPIO expander. The peripheral set includes DMA, a temperature sensor, and watchdog timers (PDR, POR, PVD, WDT) that simplify power-management and fault-recovery logic in unattended equipment.

Frequently asked questions

What is the operating frequency of STM32F051R8T7?

The core runs at 48 MHz, which is the standard clock speed for the STM32F0 series Cortex-M0 devices.

What package does STM32F051R8T7 come in?

It is supplied in a 64-LQFP package (10x10 mm body) on Tray.

Can STM32F051R8T7 replace STM32F051R8T6?

They are pin-compatible and functionally identical; the T7 version is the wider-temperature variant for harsher environments.
