LQFP Package Specifications: Dimensions, Pin Counts & PCB Design

LQFP (Low-profile Quad Flat Package) is the most common package type for STM32 microcontrollers in B2B transactions. Understanding package dimensions and pin configurations is crucial for PCB design, component sourcing, and manufacturing planning when you sell on Alibaba.com ^[3].

LQFP Package Dimensions & Pin Configuration for STM32

Package Type	Pin Count	Body Size	Pin Pitch	Height	Typical GPIO Count	Common STM32 Models
LQFP32	32 pins	7x7mm	0.8mm	1.4mm	26-28	STM32F030, G030, C011
LQFP48	48 pins	7x7mm	0.5mm	1.4mm	39-43	STM32F103, F401, G431, U535
LQFP64	64 pins	10x10mm	0.5mm	1.4mm	50-55	STM32F446, G474, U545, H563
LQFP100	100 pins	14x14mm	0.5mm	1.4mm	81-86	STM32F429, F756, H743, U575
LQFP144	144 pins	20x20mm	0.5mm	1.4mm	114-119	STM32F469, F769, H750, N650
LQFP176	176 pins	24x24mm	0.5mm	1.4mm	140+	STM32H7A3, N680

Package dimensions follow JEDEC standards. Pin pitch 0.5mm is standard for most STM32 LQFP packages, balancing solderability and pin density ^[3].

The LQFP64 (10x10mm) package has become the de facto standard for mid-range STM32 applications. It offers 50+ GPIO pins while maintaining manageable PCB footprint—ideal for industrial control boards, motor drivers, and IoT gateways. The 0.5mm pin pitch is compatible with most PCB assembly houses in Southeast Asia, reducing manufacturing costs ^[3].

PCB Design Tip: For LQFP packages with pitch ≤0.5mm, use mask-defined pads with solder mask opening slightly larger than pad size. Stencil thickness should be 0.12-0.15mm for fine-pitch components to prevent solder bridging ^[3].

LQFP vs TQFP: While both are quad flat packages, LQFP (1.2-1.4mm height) offers better mechanical robustness for industrial applications with vibration or thermal cycling. TQFP (~1.0mm height) is thinner and preferred for consumer electronics where space is critical. For B2B exporters on Alibaba.com targeting industrial buyers, LQFP is the safer recommendation ^[3].

LQFP packages are preferred for industrial applications due to their robustness and ease of rework. The 0.5mm pitch is a good balance between pin density and manufacturability for most PCB assembly houses. ^[3]
