With 140 I/O lines in the 176-LQFP package, you can route a parallel LCD, an Ethernet PHY, and a CAN transceiver without multiplexing conflicts. It is not AEC-Q100 qualified, so it does not belong in an automotive under-hood or chassis-domain BOM. ## 176-LQFP — rework and layout notes The 176-LQFP (24x24 mm body) has a 0.4 mm pitch — fine enough that a misplaced via under the toe of the lead can cause a solder bridge.","metaTitle":"STM32F429IET6 ARM Cortex-M4 MCU, 180 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32F429IET6 32-bit MCU with 180 MHz ARM Cortex-M4, 512 KB Flash, 256K x 8 RAM, 140 I/O, 176-LQFP.
