Introduction to Voice Chip WT588D

WT588D can not only be used as a general voice chip and a slave chip to generate sound, but also can be used as a FLASH microcontroller because of its multiple I/O ports, control functions and external FLASH memory. Most importantly, it can be directly masked according to the sample without changing the pins at all, and the price is half the price.

WT588D has excellent performance, is easy to use, and has very similar performance to 51 single-chip microcomputers, so we recommend it to you. To understand voice chips, start with WT588D.

Advantages of WT588D:

1. Because it is FLASH, it can be erased and written repeatedly, and the price is cheap, which is especially suitable for early developers and electronics enthusiasts.

2. The development tool is very simple, just a USB mini downloader. With a chip and a USB downloader, you can start development and freely make personalized products.

3. Support ISP programming, no need to separate the chip from the on-site environment, easy to change voice and upgrade program.

4. Equipped with learning materials: sample programs, application cases, and circuit diagrams are given for free. A development board will be launched soon.

5. After successful development, FLASH can be used in the early stage of small batches. When the market matures and large-scale launch is launched, mask can be considered. The price will drop sharply by 1/2 to 1/3, while the circuit characteristics, sound quality and pins remain completely unchanged.

6. WT588D can be used as a single-chip microcomputer to realize control functions. If your product needs to realize the functions of "control + voice", it is just right to use WT588D, and even the single-chip microcomputer is saved. This is to reduce the size and cost and increase the profit margin.

7. According to customer needs, we can provide circuit board modules or chipset solutions. Flexible methods.

Features of WT588D:

.External 2M~32M Flash, time from 32-1054 seconds. Mask is built-in ROM, maximum support 400 seconds (@6K sampling). Sampling rate supports 6K~22K

.DAC output: 13Bit, PWM output: 12Bit

.Built-in 0.5W amplifier, can directly drive 0.5W/8Ω speaker

.Support loading MP3/WAV/WMA audio formats

.Working voltage: DC2.8V～5.5V

.Quiet sleep current: <10uA

.You can combine voices at will through computer software, insert silence, and the inserted silence does not occupy the memory capacity. A loaded voice can be repeatedly called to multiple addresses, and repeated calls do not occupy space, which is not available in other chips.

.USB download mode, supports online download/ISP download

.7 control modes: MP3 control mode, key control mode, 3×8 matrix control mode, parallel port control mode, one-line serial port control mode, three-line serial port control mode and three-line serial port control I/O port expansion output mode

.The pins after masking are the same as before, with the same performance and sound quality. No need to change the circuit. No need to solder FLASH

. Up to 500 voice segments can be loaded; 210 segments can control the address bit, and a single address bit can load up to 128 voice segments, and the voices in the address bit can be played in combination;

.The inserted mute time ranges from 10ms to 25min; mute does not occupy storage space;

Application areas: automotive electronics, home appliance control, high-end smart toys, educational games, communications, industrial control, intelligent transportation, instrumentation, etc.

2. The relationship between FLASH capacity and voice storage time when the chip has a 6K sampling rate:
