KT148A Voice Chip Issue: Difficult to Play with Code Sending - Normal Playback After Grounding Pin 4, What’s the Reason?

图片
Problem Description: Hello, we’ve encountered an issue and would appreciate your support: With the KT148A chip, after powering on, sending the code rarely triggers playback. However, if we use tweezers to briefly short Pin 4 (PB0) to ground and then send the code again, playback works normally. What could be causing this? Based on the observed behavior, it’s highly likely an issue with the timing of one-wire communication,  particularly with the start signal, which may be too short.  Let’s analyze this in detail and review the KT148A schematic as follows: 1. Pin 4 (PB0) of the Chip: PB0 is a test pin with the default factory function of triggering wake-up and playback when grounded. 2. Customer Description: When the customer uses tweezers to short PB0 (Pin 4) to ground, it follows this principle. The shorting action actually performs two operations: Action 1: The KT148A detects a falling edge signal, wakes up, exits low-power mode, and enters full-speed operation. Action 2: Th...

KT1025A Dual-Mode Bluetooth Audio Chip Layout Description and Design Precautions

图片
  1. Brief Overview 1. First, please refer to the provided BT201 test DEMO module as the standard. 2. If using the chip independently without testing the BT201 module and directly proceeding to layout, background noise is highly likely if experience is limited. Therefore, always compare with the manufacturer’s test board first. 3. The BT201 solution does not include FM functionality. Please note this. The FM circuit should be left floating without hesitation 2. Precautions 1. Background noise or interference is common in Bluetooth audio products. Do not be careless during layout. 2. If you have not worked on audio products before, study online resources thoroughly. Assuming things casually will naturally lead to noise issues. 3. The core principle is to separate analog ground and digital ground. If unclear, consult an experienced engineer. 4. Ensure a clean power supply. Use an LDO whenever possible instead of a DC-DC converter. 5. Bluetooth operates at high-frequency RF and radiat...
