What are the characteristics of the Flash voice chip? Will it be better than the OTP voice chip?

FLASH voice chip and OTP voice chip are two common voice chips, but they have obvious differences in storage methods, usage scenarios, and application advantages.

1. Storage method

FLASH voice chip: Its storage method is non-volatile memory, which means that its data will not be lost, can be stored for a long time, and can maintain data integrity even in the event of a power failure.

OTP voice chip: Its storage method is a one-time programmable memory. Once the data is programmed, it cannot be modified, that is to say, its storage content is immutable.

2. Supporting tools

FLASH voice chip: FLASH chips usually require a special programmer or supporting software for programming and erasing operations. These programmers and software usually require additional costs and specialized skills.

OTP voice chip: Since the OTP chip can only be programmed once, no special programmer or software is required.

3. Repeat programming/replacing the sound

FLASH voice chip: the audio data stored in the chip can be replaced at any time through a programmer or other methods, and supports multiple programming and erasing. The sound stored in the chip can be easily replaced by changing the program code or replacing the chip itself.

OTP voice chip: Since the OTP chip is one-time programming, it cannot be programmed repeatedly, and the audio data stored in the chip cannot be changed. If the sound needs to be replaced, the entire chip needs to be replaced.

4. Cost

FLASH voice chip: Since the FLASH chip can be programmed and erased repeatedly, it requires professional production equipment and technology, so the cost is relatively high, but as the production scale increases, the cost will decrease accordingly.

OTP voice chip: Since the OTP chip can only be programmed once, it is relatively simpler and cheaper. Compared with the FLASH voice chip, the mass production scale will be larger.

5. Application Scenarios

FLASH voice chip: It is more suitable for products that need to change voice content frequently. If you need higher flexibility and capacity, you can choose FLASH voice chip.

OTP voice chip: It is mostly used in low-end products, such as small toys, alarms, electronic locks, electronic pianos, etc. This kind of voice chip that can only be programmed once is relatively low in cost and high in cost performance. Or if you need high confidentiality and security, or a smaller storage unit, then you can choose an OTP voice chip.

On the whole, FLASH voice chips and OTP voice chips have their own advantages and application scenarios. FLASH chips are suitable for applications that require large-capacity storage and reprogrammable applications, while OTP chips are suitable for applications that require high confidentiality, low cost, and miniaturization. . Choosing an appropriate chip according to specific needs and application scenarios can better meet design requirements and reduce costs.
