TSC2046EQPWRQ1 from Texas Instruments, in a TSSOP-16. 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 | +VCC | power_in | Power supply, 2.2 V to 5.25 V operation per the features list (2.7 V to 5.25 V for the internal reference), with +VCC ≥ IOVDD. |
| 2 | X+ | bidirectional | X+ position input to the touch screen, with a driver switch on-resistance of 5 Ω typical and 50 mA maximum drive current. |
| 3 | Y+ | bidirectional | Y+ position input to the touch screen, with a driver switch on-resistance of 5 Ω typical and 50 mA maximum drive current. |
| 4 | X- | bidirectional | X- position input to the touch screen, with a driver switch on-resistance of 6 Ω typical and 50 mA maximum drive current. |
| 5 | Y- | bidirectional | Y- position input to the touch screen, with a driver switch on-resistance of 6 Ω typical and 50 mA maximum drive current. |
| 6 | GND | power_in | Ground; must be connected to a clean ground point. |
| 7 | VBAT | power_in | Battery monitor input, measuring battery voltage from 0 V to 6 V. |
| 8 | AUX | input | Auxiliary input to the ADC. |
| 9 | VREF | power_in | Voltage reference input/output; the internal 2.5 V reference can be overdriven by an external source between 2 V and +VCC. |
| 10 | IOVDD | power_in | Digital I/O power supply, 1.5 V to 5.25 V, which must not exceed +VCC. |
| 11 | PENIRQ | output | Pen interrupt output. |
| 12 | DOUT | tri_state | Serial data output, shifted on the falling edge of DCLK, and high impedance when CS is high. |
| 13 | BUSY | tri_state | Busy output, high impedance when CS is high. |
| 14 | DIN | input | Serial data input; if CS is low, data are latched on the rising edge of DCLK. |
| 15 | CS | input | Chip select input that controls conversion timing and enables the serial input/output register; CS high = power-down mode (ADC only). |
| 16 | DCLK | input | External clock input that runs the SAR conversion process and synchronizes serial data I/O. |
