Working Principle of the ATF750C-15PC

The ATF750C-15PC CPLD is designed in such a way that the user can easily program the device to implement the desired functionality. The device consists of two components - an embedded 8-bit microcontroller and flash memory, which allows the user to store preprogrammed code for the device. The code is then executed by the microcontroller, controlling the CPLD to perform the desired functions. The CPLD can also be programmed to act as an interface between the external controller and the memory, enabling the user to write data to or read data from the memory.

The device also features external reset and interrupts, which allow the user to set up a reset sequence or interrupt the microcontroller when needed. The CPLD is able to switch off internal devices, such as the timer and ADC, and to operate in low-power mode to reduce power consumption. This makes the ATF750C-15PC suitable for applications that require low-power operation and remote control.

The CPLD can be programmed with Atmel’s Acoustic Engine (AUE) and C language development tools. The AUE supports the standard C language and provides user-programmable functions and macros for managing CPLD application code. The Acoustic Engine tool also includes an integrated code compiler and emulator that can be used to create and debug coding. In addition, the device contains an internal voltage reference, enabling the user to fine-tune the microcontroller and CPLD parameters.

Conclusion

The Atmel ATF750C-15PC CPLD is a versatile device that can be used in a variety of embedded applications. It is well suited for applications that require low-power operation and remote control, and its Acoustic Engine programming support and C language development tools make it simple to use. Its ability to switch off internal devices and operate in low-power mode makes it an ideal choice for a range of embedded applications.
