MCU-0401 4-Bit Keypad Capacitive Touch Module
Product Information:
Touch ICs designed using the capacitive sensing principle have stable sensing methods that can be applied to various electronic products. The panel media can be completely insulated materials, designed to replace traditional mechanical switches or ordinary keys. Provide 4 touch inputs, 4 direct output pins, and 4 LED indicators.
1. Working voltage: 2.0V~5.5V
2. Power consumption 11.5uA, low power consumption mode only 4uA (both at 3V and no load)
3. External configuration pins are set to multiple modes
4. High reliability, built-in jitter removal circuit on the chip, which can effectively prevent misoperation caused by external noise interference
5. Can be used on media surfaces such as glass, ceramics, and plastics
6. There is an automatic calibration function. When no keys are touched, the system recalibration cycle is approximately 4.0 seconds
7. The key pad can be welded with a spring key to touch
