The 24-channel 12-bit ADC and 2-channel 12-bit DAC cover analog sensor acquisition and control outputs without external converters. The 208-LQFP package (28x28 mm) is a standard fine-pitch QFP that reflows with conventional lead-free profiles and is inspectable under AOI — no X-ray needed. The 168 I/O are all 5 V-tolerant on the digital pins, simplifying level translation when interfacing to legacy 5 V peripherals. The STM32F4 series has broad ecosystem support, so second-sourcing across density and package variants within the family is straightforward without a PCB respin.","metaTitle":"STM32F429BIT7 STM32F4 MCU, 180 MHz, 2 MB Flash, 208-LQFP","metaDescription":"STMicroelectronics STM32F429BIT7 ARM Cortex-M4 MCU, 180 MHz, 2 MB Flash, 256 KB SRAM, 168 I/O, -40 to 105°C.

For a lower-power, lower-performance alternative, the STM32L151CBU6A (Cortex-M3, 32 MHz, 32 KB Flash) is a different class of device and not a direct pin-compatible replacement. Within the STM32F4 family, density and package variants share the same core architecture and peripheral set, allowing a software-compatible migration without a PCB change."},{"question":"Does STM32F429BIT7 fit into existing STM32F4 designs?","answer":"Yes. The STM32F429BIT7 is pin-compatible with other STM32F4 devices in the 208-LQFP package. The same PCB footprint and supply rails work; firmware may need minor adjustments for Flash and RAM size differences. The 180 MHz core and 2 MB Flash are at the high end of the series, so existing designs with lower-density F4 parts can drop in this part for extra headroom."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F429BIT7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F429BIT7 when reusing this data.
