![]() the XR88C92).įor my uses though, I chose the NXP SC16C752. At the time of writing, many of the hobbyist-friendly PLCC versions of these chips are listed as end of life, though I’ve since found pin and software-compatible versions of this made by MaxLinear (eg. I spent some time investigating alternative UART IC’s, and found some discussion on about replacing the 6551 with an NXP industrial (SC26 or SC28 series) UART. It would take very careful programming to avoid losing bytes with a 65C51N in this setup. I am planning to run at a higher baud rate, and the system will have multiple interrupt sources. The other 65-series chips I’m using support a wide voltage range. It runs at 5v, and I’m planning to convert the design to 3.3v later on. ![]() ![]() I am now building a 16-bit computer, and I want to avoid the 65C51N, for two main reasons: I used the WDC 65C51N to provide a UART interface, and I found it to be quite limited. I built a 65C02-based computer last year, which uses a serial connection for text I/O. This blog post shows the simple test program and circuit that I used. I recently tested the SC16C752 UART from NXP with my 6502 computer, and I was able to use it to receive and send characters.
