Smart speakers are a type of smart home product that has emerged in recent years. They integrate audio processing and voice recognition technologies to provide users with a more convenient and enriched audio experience. The MCU is a crucial core component in smart speakers. This article mainly introduces an application scheme for the 8-bit MCU TM57P8620/P8625 in smart speakers, as well as its application advantages.
The basic principle of smart speakers is to convert user voice commands into machine-recognizable digital signals through voice recognition technology, and process and synthesize audio using audio processing technology, ultimately outputting to the user. The MCU, as the core control unit of the smart speaker, is responsible for processing voice commands, controlling the audio processing module, and communicating and cooperating with other modules.
The TM57P8620/P8625 integrates a high-efficiency TM57 core, paired with an accurate low-power clock. With high anti-interference EFT/ESD performance requirements, it is very suitable for application in energy-saving AC Timer products such as smart speakers. In addition, this MCU is designed with an intelligent electronic timer specification, which can automatically control time with precision, allowing for the setting of 40 different modes to turn the power on or off, and can be set for timing within 1-24 hours or for weekly cycles. Moreover, it can be used for built-in rechargeable batteries, eliminating the need for battery replacements.
Features of TM57P8620/P8625:
2. Timepiece Current (CPU off, LCD on, using 32K crystal oscillator):
P8620: 7uA@VDD=3V, VBAT=3V, without power saving
P8620: 3uA@VDD=1.5V, VBAT=3V, with power saving
P8625: 2uA(1/2bias) or 4uA(1/3bias) @VDD=1.5V, VBAT=1.5V
3. ROM: P8620: 2Kx14bit OTP
5. Operating Temperature Range: P8620: -40°C to +85°C
Other applications of TM57P8620/P8625: controlling fans, monitors, water dispensers, aquaculture, gardening irrigation, etc.
