STM32C551CEU6
STMicroelectronicsSTM32C551CEU6 is an STMicroelectronics STM32C5 mainstream microcontroller in a UFQFPN-48 package (7 x 7 mm), sharing its die with the LQFP-100 version: Arm Cortex-M33 with FPU and DSP at 144 MHz, 512 KB of dual-bank Flash, 128 KB of SRAM, an I3C port and USB 2.0 full-speed on a 2.7 to 3.6 V supply. Selection advice: the difference against the VET6 code is only the package and the I/O count it can expose - choose CEU6 for small or height-constrained boards, and the leaded CET6 (LQFP-48) in the same pin count when hand soldering or optical inspection matters; CEU6 is supplied in trays, the tape-and-reel form is CEU6TR. ST announced the series entering production in March 2026 and the eStore lists this exact code as Active. Parameters verified against ST documentation.
