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.","metaTitle":"STM32L451CCU6 ARM Cortex-M4 MCU, 80MHz, 256KB Flash","metaDescription":"STMicroelectronics STM32L451CCU6 32-bit ARM Cortex-M4 MCU at 80MHz with 256KB Flash and 160K x 8 RAM in 48-UFQFPN.
