TSC2046EIPWR from Texas Instruments, in a TSSOP-16-EP. 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; specified performance is 2.7 V to 3.6 V and the operating range is 2.2 V to 5.25 V. |
| 2 | X+ | passive | X+ touch-screen position input; the datasheet gives switch on-resistance of 5 Ω for the Y+ and X+ drivers and an absolute analog input range of −0.2 V to +VCC + 0.2 V. |
| 3 | Y+ | passive | Y+ touch-screen position input; the datasheet gives switch on-resistance of 5 Ω for the Y+ and X+ drivers and an absolute analog input range of −0.2 V to +VCC + 0.2 V. |
| 4 | X− | passive | X− touch-screen position input; the datasheet gives switch on-resistance of 6 Ω for the Y− and X− drivers and an absolute analog input range of −0.2 V to +0.2 V on the negative input. |
| 5 | Y− | passive | Y− touch-screen position input; the datasheet gives switch on-resistance of 6 Ω for the Y− and X− drivers and an absolute analog input range of −0.2 V to +0.2 V on the negative input. |
| 6 | GND | power_in | Ground; the datasheet requires a clean ground point, normally the analog ground, kept away from microcontroller or DSP ground returns. |
| 7 | VBAT | power_in | Battery monitor input; the input voltage range is 0.5 V to 6.0 V. |
| 8 | AUX | input | Auxiliary input to the ADC; the absolute input range is −0.2 V to +VCC + 0.2 V. |
| 9 | VREF | power_in | Voltage reference input/output; the internal 2.5 V reference can be overdriven by an external low-impedance source between 1 V and +VCC. |
| 10 | IOVDD | power_in | Digital I/O power supply; the operating range is 1.5 V to +VCC, and IOVDD must not exceed +VCC. |
| 11 | PENIRQ | output | Pen interrupt output for touch detection. |
| 12 | DOUT | tri_state | Serial data output; data shift on the falling edge of DCLK, and the output is high impedance when CS is high. |
| 13 | BUSY | tri_state | Busy output; the output is high impedance when CS is high. |
| 14 | DIN | input | Serial data input; when CS is low, data are latched on the rising edge of DCLK. |
| 15 | CS | input | Chip select input; it controls conversion timing and enables the serial input/output register, and CS high puts the ADC in power-down mode. |
| 16 | DCLK | input | External clock input; it runs the SAR conversion process and synchronizes serial data I/O. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
