Product description:

Overview WTN6F series is a low-cost, high-performance CMOS voice chip. The biggest feature is that it can be burned repeatedly. The existing WTN6020-8S-F-B with a voice length of 20s and WTN6040-8S-F-B with a voice length of 40s support the replacement of the downloader, with 100KB voice space. The audio sampling rate is currently up to 32kHz, 16 level volume control, PWM output mode. The chip works in a wide voltage range of 1.8V~5.5V. Function description (1) Working voltage: 1.8V~5.5V; (2) Reset condition: low voltage reset (LVR=1.7V) or power-off reset; (3) 12 bit PWM pure audio output can directly drive 8 Ω/0.5W horn; (4) Support 1-wire serial port and 2-wire serial port control (up to 224 segments of voice can be loaded, which will be explained in detail later) (5) Support BUSY status output (the standard program BUSY pin defaults to high level, and it is low level during voice playback.

Because WTN6 needs a certain initialization time (about 100MS) to power on, and cannot respond to commands during initialization, it needs to complete initialization to receive control commands normally. 2. Using 4R speakers or parallel speakers may cause the chip PWM to appear LATCH-UP phenomenon, which will result in failure to play. It needs to be powered on again to recover, and the chip may be burned in serious cases. 3.

summary

WTN6 F series is a low-cost, high-performance CMOS voice chip. The biggest feature is repeatable burning 。 The existing WTN6020-8S-F-B with a voice length of 20s and WTN6040-8S-F-B with a voice length of 40s, WTN6040-8S-F-B supports the replacement of downloader , there is 100KB voice space. The audio sampling rate is currently up to 32kHz, 16 level volume control, PWM output mode. The chip works in a wide voltage range of 1.8V~5.5V.

Function description

(1) Working voltage: 1.8V~5.5V;

(2) Reset condition: low voltage reset (LVR=1.7V) or power-off reset;

(3) 12 bit PWM pure audio output can directly drive 8 Ω/0.5W horn;
