Operating voltage: 2.4V~5.5V
Built-in system voltage stabilization circuit, power stability, 0.5s
Multiple modes (latch / trigger / open leakage) are externally configured to set the CMOS high / low level output
Working mode power consumption is 20 uA, and low power consumption mode is 5 uA (at 3.0V with no load)
Operation mode is selected by port LPMP, key response time is 45ms and response time in low power mode is 160ms
Single key or multiple key output mode is selected by the SM port
The sensitivity of the chip input detection channel can be adjusted separately
After system stabilization time of about 0.5 seconds, do not touch Touch Pad during this period, and the touch function is invalid
Automatic calibration function. The calibration period within 8s after power-on is 1s. If there is a key touch within 8s or no input after 8s, the system calibration period is switched from 1s to 4s
High reliability, the chip built-in jitter circuit, can effectively prevent external noise interference caused by misoperation
Can be used in glass, ceramic, plastic and other media surface
