STOTG04ESQTR

STMicroelectronics · USB Converters · QFN-24-EP(4x4)

STOTG04ESQTR from STMicroelectronics, in a QFN-24-EP(4x4). 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 ADR_PSW bidirectional Least significant bit of the I2C address, latched on reset, and PSW output enabling or disabling an external charge pump.
2 SDA bidirectional I2C serial data line, an input and open-drain output.
3 SCL input I2C serial clock input.
4 RESET/ input Active low logic reset input.
5 INT/ output Active low interrupt signal output, open-drain.
6 SPEED input Selects transceiver mode (0 = low-speed, 1 = full-speed), an input with internal pull-up resistor.
7 VTRM power_out Internal voltage regulator output; an external 1µF decoupling capacitor should be connected, and the regulator can be bypassed by tying this pin to VBAT when VBAT is 2.7V to 3.6V.
8 SUSPEND input Power-down input (0 = active mode, 1 = power-down mode).
9 OE_TP_INT/ bidirectional Output enable of the differential driver in USB mode, or interrupt output.
10 VM output D- single-ended receiver output.
11 VP output D+ single-ended receiver output.
12 RCV output Differential receiver output.
13 SE0_VM bidirectional Single-ended zero input/output in DAT_SE0 transmit mode, negative data input/output in single-ended transmit mode, or TXD in UART mode.
14 DAT_VP bidirectional Data input/output in DAT_SE0 transmit mode, positive data input/output in single-ended transmit mode, or RXD in UART mode.
15 D- bidirectional Negative data line in USB mode, or serial data output in UART mode.
16 D+ bidirectional Positive data line in USB mode, or serial data input in UART mode.
17 GND power_in Common analog and digital ground.
18 ID bidirectional ID pin of the USB connector used for protocol identification.
19 VBUS power_in VBUS line of the USB interface, which needs an external 4.7µF capacitor.
20 VBAT power_in Analog power supply voltage, +2.7V to +5.5V.
21 CAP1 bidirectional External capacitor pin for the charge pump, with a 220nF capacitor between CAP1 and CAP2.
22 CAP2 bidirectional External capacitor pin for the charge pump, with a 220nF capacitor between CAP1 and CAP2.
23 CGND power_in Ground for the charge pump.
24 VIF power_in Logic power supply, +1.6V to 3.6V.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
