Vlastnosti
XMEGA Custom Logic (XCL) — The AVR XMEGA E devices feature an innovative XMEGA Custom Logic module (XCL) consisting of two independent 8-bit timers/counters and two lookup tables used for defining glue logic. It is designed to reduce bill of material (BOM) and PCB size as the XCL can replace external circuitry such as delay elements, RS-latches, D-latches, D-flip-flops chip-select logic, AND, NAND, OR, NOR, XOR, XNOR, NOT, MUX AND/OR/XOR logic gates. In addition, it can, together with the USART, enable customized communication protocols.
WeX – Waveform Extension
New Output Matrix sub-function has been developed in WeX for Power control systems (such as SMPS) and Lighting applications.
The waveform extension (WEX) provides extra functions to the timer/counter in waveform generation (WG) modes. It is primarily intended for motor control, ballast, LED, H- bridge, power converters, and other types of power control applications. The WEX consist of five independent and successive units, as shown in Figure:
Vylepšený WeX modul, má oproti predchádzajúcemu AWeX modulu, používanom v predchádzajúcich sériach Megy tieto vylepšenia:
