List: OTP Voice ICs

OTP (One Time Programmable) voice chip means one-time programmable voice chip, Widely used in electronic locks, home appliances, and various application scenarios that require convenient sound prompt

WTN6040-8S & WTN6170-8S OTP Voice IC from Waytronic support 40S and 170S speech duration under 6k sampling rate (Voice with a sampling rate of 6kHz=acceptable Phone call sound quality), when The sampling rate increased to 12kHZ, their speech duration can support 20s(WTN6040-8s) and 85s(WTN6170-8s) with High-quality sound

On the other hand, WTN6 series chips can support multiple control methods such as single-chip microcomputers or keys, they can directly drive 8 ohms 0.5watt speaker (PWM output) or external power amplifier (DAC output)
