S83C741

8-bit single-chip microcontroller featuring the high-performance 80C51 core, 4KB of factory-programmed internal masked ROM, 128 bytes of RAM, and a full hardware I2C serial bus. | 28-Pin PLCC / DIP Package | Mid-1990s television tuning control decks, commercial VCR servo panels, early home automation smart hubs. | S83C741 | None | None | P83C741, 83C741, 83C751 (Related footprint series), 83C752 | Legacy MIDI-to-I2C Hub Controller: Programmed via its standard 8051 instruction block to sample high-speed asynchronous serial MIDI bytes from an instrument controller and cleanly parse the data into I2C protocol strings for custom synthesizer voices. | Philips / NXP Consumer Electronics Mainframe Sub-Systems: This custom 8051 derivative was engineered by Philips Semiconductors specifically to run low-cost, dedicated peripheral macro-routines in television chassis and automated multi-device master control panels.
