Product details

The STM32L451CCU6 is an STMicroelectronics STM32L4 series 32-bit ARM Cortex-M4 single-core microcontroller running at 80 MHz. On the peripheral side it integrates a 10-channel 12-bit ADC and a single 12-bit DAC for analog interfacing, plus CANbus, I2C, IrDA, LINbus, QSPI, SAI, SPI, and multiple UART/USART channels. The 38 available I/O pins in the 48-UFQFPN package give enough headroom for a modest sensor array or a human-machine interface with a small display and keypad.

Active lifecycle — supply posture for this line item

New designs can commit to this order code without an LTB risk horizon. For dual-sourcing resilience, the base product number STM32L451 covers a density and package family — the CCU6 suffix identifies the 256 KB Flash, 48-pin UFQFPN variant, and pin-compatible siblings with different Flash sizes share the same footprint.

Frequently asked questions

What is STM32L451CCU6's core speed and memory configuration?

The ARM Cortex-M4 core runs at 80 MHz. Program memory is 256 KB of Flash, and SRAM is 160K x 8. This combination handles real-time control firmware with moderate data buffering.

Can STM32L451CCU6 be programmed using ST-Link?

Yes, the STM32L4 family supports SWD (Serial Wire Debug) which is the protocol used by ST-Link programmers. The debug interface is available on the SWDIO and SWCLK pins.
