Editor's Note: I've long been impressed by Xcell Journal from Xilinx, both for the quality of its production and the quality of its articles. So I'm delighted to have the opportunity to present the ...

The purpose of the prototype was to design and implement simple asynchronous transmitter and receiver logics with TTL-RS232 serial communication. The transmitter and receiver were designed as state ...

The chip [Andrew] chose was a Xilinx XC2C32A, a cheap but still modern CPLD. The first step to probing the signals was decapsulating the chip from its plastic prison and finding some interesting ...

This paper studies on the elimination of the competitive and narrow pulse interference and on the reliability of the reset circuit in CPLD design. Methods of additional trigger, delay superposition, ...

Requires a larger CPLD with higher density and I/O pin count. Complex CPLD increases solution cost. Routing low-voltage analog telemetry to a single location increases circuit board congestion. Forces ...

Thus, the first method is the most practical, and we'll show how we at Retro Devices Technology did it using a Xilinx XC9536XL CPLD – specifically targeted for 5V transistor-to-transistor logic (TTL ...
