Cypress Capacitive Touch Sensor Solution 3

CapSense is based on Cypress' CY8C21X34. html "target=" -blank "title=" CY8C21X34 ">CY8C21X34 series PSoC devices. Cypress's PSoC mixed signal array is a programmable SOC that integrates microcontrollers with analog and digital components typically located in the form of embedded systems around it. A single PSoC device can integrate up to 100 peripheral components and a microcontroller, saving customers design time, board level space, power consumption, and system costs. Future PSoC products will also support CapSense.

CY8C21X34 has 8kb flash memory for program storage; 512 byte SRAM for data storage; Maximum speed of 24MHz; And it adopts 16 pin SOIC, 32 pin MLF, and 20 pin and 28 pin SSOP packaging. The current bulk production price of this product is 0.99 US dollars.  diode
