Product details

Industrial temperature range and analog integration

The STM32F334C8Y7TR: Integrates 15 channels of 12-bit ADC and 3 channels of 12-bit DAC.

Peripherals and connectivity for control applications

The DMA controller offloads data movement from the CPU, and the POR (Power-On Reset) and WDT (Watchdog Timer) provide the supervision needed for unattended equipment. The 12-bit ADC resolution (15 channels) and 12-bit DAC (3 channels) are a strong match for digital power conversion and motor-control feedback loops.

49-WLCSP package — rework and layout notes

The 49-WLCSP package measures 2.89 x 3.74 mm.

Frequently asked questions

Is STM32F334C8Y7TR equivalent to STM32F334C8Y6?

The STM32F334C8Y6 is a close sibling in the same STM32F334 family, sharing the same core, Flash and RAM sizes, and peripheral set. The difference is typically in the package variant or temperature range — the Y7TR uses the 49-WLCSP package in Tape & Reel. Check the specific package code and temperature grade on the Y6 variant to confirm pin-to-pin compatibility for your board.

Does STM32F334C8Y7TR have a built-in bootloader?

Yes. Like all STM32 devices, it includes a factory-programmed bootloader in system memory that supports USART, I²C, SPI, and CAN interfaces for programming over the serial wire. The bootloader is activated by pulling the BOOT0 pin high on reset.
