Brown-out detect, POR, and a programmable watchdog are on-chip, so a separate supervisor IC is optional for most industrial applications. The base product number is STM32F423, which shares the same pinout and memory map across the density variants — a BOM consolidation point if you also use the 512 KB or 1 MB Flash siblings in the same family. Housed in a 144-LQFP with a 20x20 mm body and 0.5 mm pitch. The exposed pad (if present on this variant) should be stitched to ground with thermal vias if the application draws more than about 200 mA continuous from the core.","metaTitle":"STM32F423ZHT6 STM32F4 MCU, 100MHz, 1.5MB Flash, 144-LQFP","metaDescription":"STMicroelectronics STM32F423ZHT6 ARM Cortex-M4 32-bit MCU at 100MHz with 1.5MB Flash and 320KB SRAM.
