STM6524AHARDL6F

STMicroelectronics · Supervisor And Reset ICs · UDFN-6(1.3x1.6)

STM6524AHARDL6F from STMicroelectronics, in a UDFN-6(1.3x1.6). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VSS	power_in	Ground pin for the device, serving as the ground reference for all signals.
2	SR1	input	Secondary push-button Smart Reset input, active low with optional pull-up resistor; both SR inputs must be asserted simultaneously for at least tSRC to assert RST.
3	RST	output	Reset output, active low or active high, push-pull or open drain with optional pull-up resistor; it is deasserted below 1.575 V typ. and its state is guaranteed down to 1 V.
4	NC	unconnected	Not connected; not bonded internally and should be connected to VSS.
5	SR0	input	Primary push-button Smart Reset input, active low with optional pull-up resistor; applying a voltage of VCC + 0.9 V to VCC + 1.4 V (VTEST) enters test mode.
6	VCC	power_in	Positive supply voltage for the device, 1.65 V to 5.5 V; a 0.1 µF ceramic decoupling capacitor is recommended between VCC and VSS, as close to the device as possible.

CAD (KiCad official)

Symbol: STM6524AHARDL6F
Footprint: Package_DFN_QFN:DFN-6_1.6x1.3mm_P0.4mm
3D model: UDFN-6(1.3x1.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: stm6524ahardl6f-etched.step / stm6524ahardl6f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stm6524ahardl6f.step / stm6524ahardl6f.glb are the bare package body.
