INTRODUCTION
The 82077AA is a true single-chip floppy disk, and tape drive controller for the PC-AT and PS/2. The 82077AA, a 24 MHz crystal, a resistor package and a chip select implement a complete design. All drive control signals are fully decoded and have 40 mA drive buffers with selectable polarity. Signals returned from the drive are sent through on-chip input buffers with hysteresis for noise immunity. The integrated analog data separator needs no external compensation yet allows for a wide motor speed variation with exceptionally low soft error rates. The microprocessor interface has a 12 mA drive buffer on the data bus plus 100 hardware register compatibility for PC-AT’s and PS/2’s. The 16-byte FIFO with programmable thresholds is extremely useful in multi-master systems (PS/2, EISA) or systems with a large amount of bus latency.
