Working Principle

Architecture: The CY8C20066A-24LTXI incorporates a multi-core architecture which is optimized for low power operation and real-time response. The main CPU is an Arm Cortex-M0 core clocked at 24MHz. The on-chip memory consists of 64KB flash and 8KB SRAM, while there is also provision for an off-chip SRAM up to 8KB. The on-chip clock frequency can be adjusted from 10.24MHz to 24MHz. The on-chip peripheral support includes a 16-bit PWM, set of DMA channels, I2C, SPI, UART and configurable GPIOs for system interfacing.

Program Execution: The CY8C20066A-24LTXI supports either full-application stores or a Bootloader store for secure OTA programming. External program code stored in non-volatile memory such as EEPROM and flash can be used to load the operating system and application code into the SRAM. Once the code is loaded, the CPU will execute the code according to a set of instructions. The CPU supports single-cycle instruction fetch and instruction decode, providing a very efficient instruction decoding. The CPU supports up to 24 interrupt sources. Each interrupt source has its own program address, stack, and priority.

I/O: The CY8C20066A-24LTXI supports up to thirty-two configurable GPIOs. Each of these can be configured as an input, output, or special function. Inputs can be either edge- or level-sensitive with maximum medium to small signal stability. Depending on the application, the GPIOs can be configured to support several peripherals such as SPI, I2C, UART, etc. The available analog I/O includes two ADC units and two DACs. The two ADC units can sample signals up to 12-bit differentially using either integrated or external sources.

Power Supply: The CY8C20066A-24LTXI supports a supply voltage range of 1.8 – 3.3V. Low-leakage power supply is used to create the operating environment for the microcontroller. The CY8C20066A-24LTXI also has a low-power mode, providing an extended battery life while maintaining the wake-up time under 1ms.

The CY8C20066A-24LTXI is a powerful, low-power, high-performance microcontroller designed for embedded control applications. It offers a number of powerful and configurable peripherals, an extensive range of interfaces, and a wide operating voltage range. Its specialized architecture provides a robust platform suitable for a variety of applications that require higher speeds and flexibility. The CY8C20066A-24LTXI’s multi-core architecture allows for fast and efficient execution, making it suitable for a range of applications. With its small footprint and energy-efficient features, the CY8C20066A-24LTXI is the perfect choice for embedded control applications.
