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
     • Standby State：Through a low - power mode design, the battery life cycle is effectively extended.

     - 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.
