Besides, this device can also significantly reduce your cost, as it fully integrates an 8-bit CPU, ROM and RAM, fast internal oscillator, environment sensor and two 8-bit timers. CY8C3866LTI-065 also supports a maximum of 72 I/Os and some major communication protocols, like I2C, SPI, USB and UART.

CY8C3866LTI-065 is also suitable for a variety of capacitive touch sensing applications, such as multi-button touch sensing control and digital-encoder touch sensing. Its high integration could easily reduce digital and analog design workloads like PCB layout and signal routing, as it supports on-chip programmable clock and active sensor, redundant sensor support interface, an integrated shield touch button at each input, and supports many communication protocol options such as UART, USB, I2C, and SPI.

CY8C3866LTI-065 comes with a 32MHz ARM Cortex-M0 core, as well as a Cypress PSoC (Programmable System-on-Chip) architecture, making it an ideal choice for both low-end CapSense applications and high-end microcontroller applications. It is capable of performing high speed and logic operations and provides more flexibility in data communication and memory manipulation. It is also capable of modifying and monitoring peripheral functions, making it the perfect choice for developing complicated and efficient products.

The working principle of CY8C3866LTI-065 is based on CapSense technology which is an integrated capacitance touch sensing solution from Cypress Semiconductor. It utilizes a combination of sensor, controller and communication protocol to measure the capacitance between certain points. When an object comes near or touches these predetermined points, it will cause the capacitance to increase, which can be detected by an on-chip voltage comparator. Once CY8C3866LTI-065 detects a change in capacitance, it will generate an interrupt flag and reset the timer. Depending on the user’s programming criteria, the CY8C3866LTI-065 will take the appropriate action.

In summary, CY8C3866LTI-065 is a highly integrated multi-functional device with powerful features and a unique single-chip design. It is suitable for a wide range of embedded applications due its advanced CapSense technology and on-chip peripherals. Its appealing benefits and top-notch performance make CY8C3866LTI-065 a great choice for your next project.
