MSL 3 handling applies; bake before reflow if the moisture-barrier bag has been open past the floor-life window. For dual-sourcing resilience, the STM32L4R9ZI (same base number, different package variant) is the closest sibling — verify pin compatibility against your specific layout before substituting. ## Data converters and analog integration On-chip data converters include a 16-channel 12-bit ADC and a 2-channel 12-bit DAC. For a calibration-minded build, the ADC's reference accuracy and temperature drift are worth verifying against the system's error budget — the datasheet's typical figures are a starting point, but a traceable reference check during prototype validation catches long-term drift before it becomes a field issue.","metaTitle":"STM32L4R9ZIJ6 ARM Cortex-M4 MCU, 120 MHz, 2 MB Flash","metaDescription":"STM32L4R9ZIJ6 32-bit MCU with 120 MHz ARM Cortex-M4, 2 MB Flash, 640 KB SRAM, 112 I/O, 144-UFBGA.
