CBM7026 is low-cost single chip solution for capacitive touch sensor controller. The chip is mainly used for mechanical buttons replacement in home appliances, consumer electronics, industrial areas. With robust sensing technology, it has high performance across a variety materials and thickness, high noise immunity, waterproof and dustproof.
CBM7026 is 8-bit RISC architecture microcontroller devices with I2C Host/Slave, UART interface. For function application, CBM7026 support Button information for customers. In operation mode, it can support protocol and I/O mode for customer. Developer can use I/O mode to get a valid button message and develop their system very easily, and no longer need to decode the communication package.
The capacitive touch sensor can be designed by placing a copper pad on the PCB directly, covered with a plastic or glass case. It provides auto-calibrate the parameter for a wide range of capacitance on the touch sensor(1pF ~ 40pF). The system controller converts finger data to button presses, depending on finger location and human interface context.
CBM7026 robust sense solutions leverage our flexible programmable system-on-chip architecture, which accelerate time-to-market, integrates critical system functions and reduced BOM costs. CBM7026 supports multi-package for various application.
