I. Key Features

1. Built-in LDO voltage regulator module.

2. Wide operating voltage range: 2.2V～5.5V.

3. Ultra-low power consumption; typical low-power mode: 1.5uA@VDD=3V/no load.

4. Longest button response time: Approximately 220ms@VDD=3V in low-power mode.

5. Longest duration of button press:

APS8233E, APS8233F, APS8233C, APS8233B: 16 seconds (±30%).

APS8233G: Infinite.

6. Power-on initialization takes approximately 400ms to calculate media and environmental variables. Do not touch the detection point during this period, and all functions are disabled.

7. Adjust touch sensitivity using an external capacitor (1-50pF).

8. External configuration pins can be set to various modes.

9. Output mode selection (TOG): Direct output in synchronous mode or latched (toggle) output in hold mode.

10. Active level selection (AHLB): High-level output is active, or low-level output is active.

11. CMOS Output (QC): Output is active high or active low.

12. NMOS Open-Drain Output (QD): Only valid for low-level output.

13. Features a touch environment adaptive algorithm, allowing for rapid and automatic adaptation to changes in the operating environment.

14. Includes power-on reset and low-voltage reset functions.

15. High reliability and strong anti-interference capability; the chip has a built-in debouncing circuit to effectively prevent malfunctions caused by external noise interference.

16. Operating temperature range: -40～85℃

17. HBM ESD: Greater than 5KV.
