KT142C Voice Chip: A Selection Solution for 6 - segment Music IO Control and Button - battery Power Supply


When it comes to the selection of voice chips with the requirements of independent IO control for 6 segments of music and power supply by button batteries, there are specific key points. The core is that the chip should adopt the SOP16 package to meet the configuration of 6 IO ports and be able to work under low - power conditions at around 3V.

Core Functional Requirements

  1. IO Resource Configuration：To achieve independent control of 6 segments of music, with each segment corresponding to an independent IO trigger port, at least 6 independent IO pins are required for music trigger control.
  2. Package Form Requirement：Only the SOP16 package structure can meet the required number of pins.
  3. Power Supply Characteristic Requirement：The chip should be adaptable to 3V button - battery power supply and have the ability to operate with low power consumption.

Particularities of the Power Supply System

  1. Standard Voltage：Common button batteries such as CR2032 have a standard voltage of 3V.
  2. Capacity Limit：Their capacity is usually less than or equal to 300mAh.
  3. Power - consumption Sensitivity：Standby power consumption and playback power consumption must be optimized.

Recommended Chip Solution: KT142C - SOP16

1.Hardware Adaptability

🔹 Package Specification：It adopts the SOP16 package form, with a total of 16 pins, 6 of which can be flexibly configured as independent IO trigger ports.

🔹 Storage Configuration：It has a built - in storage space of 320Kbyte, sufficient to support the storage of multiple audio segments.

🔹 Voltage Range：The operating voltage range is 2.6V - 5.5V, which is perfectly adapted to 3V button - battery power supply.

2.Functional Characteristics

🔹 Trigger Control Mode：It supports one - to - one trigger playback for 6 - way IO ports, with each IO port corresponding to an independent music segment.

🔹 Power - consumption Control

  1. Standby State：Through a low - power mode design, the battery life cycle is effectively extended.
  2. Playback State：The audio decoding power consumption is optimized to balance sound quality and power consumption.

This chip is suitable for miniaturized devices such as e - greeting cards, toy sound - generating devices, and portable reminder devices. Moreover, it is very convenient to replace the built - in voice of the chip. Just connect it directly to a PC, and the voice can be replaced quickly.

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...
