Surface-mount assembly is standard; no exposed pad means thermal dissipation depends on the leadframe and copper area on the top layer. It is not listed as NRND or nearing end-of-life, so new designs can proceed without an immediate last-time-buy clock. The date-code and marking consistency should be verified on receipt — the 100-LQFP package is a common target for re-marked parts in the gray market, so a decap or X-ray check is prudent if the lot trace does not match the authorized chain.","metaTitle":"STM32F100VDT7B ARM Cortex-M3 MCU, 24 MHz, 384 KB Flash","metaDescription":"STMicroelectronics STM32F100VDT7B 32-bit MCU with 24 MHz ARM Cortex-M3, 384 KB Flash, 32K x 8 RAM, 80 I/O, -40°C to 105°C.
