Since first releasing the 80C52 in the fall of 1987, Micromint has been the world's preeminent supplier of the chip. We continue to be the leading supplier of "BASIC on a chip." The Micromint 80C52 is a CMOS, low-power, enhanced, software-compatible successor to the original power-hungry Intel 8052AH-BASIC chip. We sell so many of these chips that we even made a PLCC version.
Our 80C52-BASIC chip was designed for industrial use and operates significantly beyond the limits of standard commercial-grade chips. The Micromint 80C52-BASIC chip is guaranteed to operate flawlessly from DC to 12 MHz over the entire industrial temperature range (40°C to +85°C). It is available in 40-pin DIP or 44-pin PLCC.
Parallel PLIX is an 18-pin CMOS chip which provides an intelligent communication interface between a computer and X-10 AC power-line control modules. PLIX removes the burden of complex X-10 programming protocol from the designer by providing a simple parallel interface. It takes care of the complex zero-crossing timing for sending and receiving X-10 commands so you don't have to. An otherwise simple embedded controller can now also feature X-10 power-line control by simply adding a PLIX chip to the design. PLIX are available in both a Parallel and Serial version.
SERIAL PLIX is designed to interface with the Serial port of any embedded controller or computer. Using simple ASCII commands, the user now has a simple way to communicate with the X-10 powerline adapter module (TW523) to control electronic devices over the existing powerlines. With a little imagination and software support from the user, Serial PLIX also has the capability to transmit and receive data segments via the powerlines. The user can select the baud rate and other parameters to obtain the desired communications protocol.
