Working Principle

The CY7C53120E4-40SXIT operates according to the principles of a microcontroller. The device is a 8-bit microcontroller with a 32-bit addressable memory map and 32-bit data path. It is programmed by the instructions stored in its program memory. The instructions are fetched and decoded and then the tasks are executed according to the instructions. The data and program memories are accessible using the integrated programming port and necessary software provided by CREE, the manufacturer of the CY7C53120E4-40SXIT. The device utilizes two 16-bit timers/counters, which can be used for interrupts, waveform generation and pulse-width modulation (PWM). The device also features direct memory access (DMA) controller to transfer block of data from the source to destination without the intervention of the CPU. The DMA controller can be programmed to repeat or burst the data flow, for faster data transfer. The device features low-power sleep mode to reduce power consumption and to increase system reliability. This can be utilized to reduce power consumption when the device is not a active hence prolonging battery life in mobile applications.Another important feature of the CY7C53120E4-40SXIT is its capability to execute real-time tasks. This is achieved by using its two on-chip 16-bit timers/counters which can be programmed to execute tasks on a predetermined time. This allows the device to process operations even though the instruction execution speed is much lower than the signal frequency.

Conclusion

The CY7C53120E4-40SXIT integrated solution is designed for applications requiring robust system control and its versatility makes it suitable for automotive, consumer and industrial applications. It utilizes 8-bit general purpose microcontroller, two 16-bit timer/counters, direct memory access controller, integrated programming port, low-power sleep mode, UART, I2C and SPI bus interfaces and more. A real-time program can also be applied to increase system reliability.
