MC1081S

Mysentech · Capacitive Sensor IC · QFN-16-EP(3x3)

MC1081S from Mysentech, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1 passive Channel 1 capacitive sensing input. Connects to sense electrode for single-ended, dual-ended floating, or mutual capacitance measurement.
2 C0 passive Channel 0 capacitive sensing input. Connects to sense electrode for single-ended, dual-ended floating, or mutual capacitance measurement.
3 SHLD output Active shield output. Drives a buffered replica of the sense signal onto guard traces to eliminate parasitic capacitance to ground. High-drive mode CLOAD up to 100pF; low-drive mode 50pF.
4 SDA bidirectional I2C serial data line. Open-drain; supports standard mode (up to 400kHz) and fast mode (up to 1MHz). Requires external pull-up.
5 SCL input I2C serial clock line input. Supports standard mode (up to 400kHz) and fast mode (up to 1MHz).
6 ADDR input I2C slave address select input. Tied high or low to select one of two I2C addresses.
7 VDD power_in Supply voltage input. Operating range 2.3V to 5.5V; absolute max 6.0V. Internal LDO regulates for oscillator driver.
8 GND power_in Ground reference. Return for supply, digital, and analog circuitry.
9 C9 passive Channel 9 capacitive sensing input. Pairs with C8 for dual-ended/mutual mode (channels 8-9 pair).
10 C8 passive Channel 8 capacitive sensing input. Pairs with C9 for dual-ended/mutual mode (channels 8-9 pair).
11 C7 passive Channel 7 capacitive sensing input. Pairs with C6 for dual-ended/mutual mode (channels 6-7 pair).
12 C6 passive Channel 6 capacitive sensing input. Pairs with C7 for dual-ended/mutual mode (channels 6-7 pair).
13 C5 passive Channel 5 capacitive sensing input. Pairs with C4 for dual-ended/mutual mode (channels 4-5 pair).
14 C4 passive Channel 4 capacitive sensing input. Pairs with C5 for dual-ended/mutual mode (channels 4-5 pair).
15 C3 passive Channel 3 capacitive sensing input. Pairs with C2 for dual-ended/mutual mode (channels 2-3 pair).
16 C2 passive Channel 2 capacitive sensing input. Pairs with C3 for dual-ended/mutual mode (channels 2-3 pair).
17 EP passive Exposed thermal pad on package underside. May be left floating or connected to GND per datasheet note 2.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Mysentech datasheet (46 pp, sha256 a057edd51418dfbd, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
