A multichannel, implantable, microcontroller system has been developed for use with biomedical systems to provide monitoring of physiological and electrical parameters such as blood flow, pressure, ECG, and battery voltage. Although the system to be described samples data from eight channels at 400 Hz, various sample rates can be used by simply modifying the software. Data is transmitted to a remote data acquisition system comprised of a personal computer or recorders outside the body over a 10 MHz FSK link at 38.4Kbaud. The system is a half duplex, asynchronous system and uses Pulse Code Modulation techniques. The use of the CMOS MC68HC11 Microcontroller has greatly reduced the size and power requirements of such a system and increased it's reliability and versatility.
