Комментарии об отличиях

CY8C20xxA ↔ TTP229-LSF

CY8C20xxA (Infineon/Cypress): CapSense MBR3, 1-16 buttons, programmable via EZ-Click config tool, I2C/SPI/UART, smart tuning algorithm (auto-calibration), low-power wake-on-touch, waterproof design, -40 to +85°C. TTP229-LSF (Tontek): 8-16 touch keys, I2C or parallel output, 8-key (1:1) или 16-key (2:1 mux), no MCU programming needed, fixed sensitivity via external cap. Отличия: CY8C20xxA — полностью programmable через GUI, поддерживаем sliders, proximity, waterproof. TTP229-LSF — fixed-function, только buttons, sensitivity set by external capacitor (10pF-50pF). Интерфейс: CY8C20xxA — rich I2C register map, TTP229-LSF — simple 8-bit parallel или basic I2C. Low power: CY8C20xxA — 20µA sleep с wake-on-touch, TTP229-LSF — 100µA standby. Подводный камень: TTP229-LSF имеет limited ESD protection (2kV HBM) vs CY8C20xxA (8kV) — для industrial apps добавить external ESD protection.
