NUC220LE3AN Working Principle

The NUC220LE3AN microcontroller operates on an 8051 RISC instruction set. This microcontroller also features a hardcoded Memory Interface Unit (MIU) controller, which is a special asynchronous memory controller that has specific memory types that are not accessible to the traditional memory access. This MIU can transfer data from the chip\'s internal RAM to the program code available in external memory. It is also capable of passing information from external memory to the internal RAM.

The NUC220LE3AN also features a direct memory access (DMA) bus for passing information from external devices to the microcontroller. DMA allows direct transfer of data from the external device to the memory with minimal CPU involvement. It is well suited for transferring a large amount of data, or where it is needed to support real-time control operations. Additionally, NUC220LE3AN also has up to 128KB of program flash memory.

NUC220LE3AN microcontroller includes two timer/counters, one 8-bit RISC CPU, two serial communications ports, and one low pin-count (LPC) port. Additionally, NUC220LE3AN has onboard clock and watchdogs, two programmable pull-up resistors, 6 inputs, and 4 outputs.

The NUC220LE3AN microcontroller also features an advanced low-power sleep mode, which is based on the SmartSleep Technology developed by Nanjig. This technology allows for reduced power consumption and improved system performance by reducing the amount of power consumed when the microcontroller is in sleep mode. The advanced power modes and low power features of NUC220LE3AN help to make it an economic investment for low power designs.

In conclusion, the NUC220LE3AN microcontroller is an 8-bit 8051 microcontroller that is highly integrated, low power, and cost-effective. It provides a wide range of hardware peripherals and software functions which make it suitable for embedded applications of many types. Its onboard MIU controller, DMA bus, and built-in clock and watchdogs make it an attractive choice for a wide range of products and applications.
