Packaging

Type: 32-LQFP (Low-Profile Quad Flat Package)

Body size: 7 mm x 7 mm

Typical thickness: around 1.4 mm (see datasheet for exact value)

Pin count: 32 leads; about 25 usable GPIO plus power, ground, and control pins

Lead pitch: typically 0.8 mm for LQFP-32

Material: Epoxy mold compound with copper leadframe

Lead finish: Lead-free, RoHS3 compliant (matte tin/NiPdAu; see datasheet for exact finish)

Mounting: Surface mount (SMT)

Supplier device package: 32-LQFP (7x7)

Delivery format: Tray

Thermal characteristics: Rated for -40°C to +125°C operation; actual thermal resistance depends on PCB and airflow (consult datasheet for thermal metrics such as θJA/θJC)

Electrical properties: 3.0V–5.5V supply, 10-bit ADC, internal oscillator, ESD and latch-up per AEC-Q100 (see datasheet for exact test levels)

Lifecycle

Status: Active and in production; not nearing discontinuation based on current family status

Family continuity: Part of the STM8A Automotive series with broad, long-term support

Equivalent/Alternative models (verify pinout and features in datasheet):

- STM8AF622x (8KB Flash, 32-LQFP, similar peripherals)

- STM8AF624x (16KB Flash, 32-LQFP; includes this device family)

- STM8AF626x (32KB Flash, 32-LQFP, higher program memory)

- STM8AL series (low-power automotive variants; check package and peripheral match)

- STM8S series (industrial-grade, non-AEC; may be pin-compatible but not automotive qualified)
