DATA SHEET DESCRIPTION
STP2001Slave Controller highly integrated, low-cost, low-power device designed single-processor systems with SBus interface. STP2001 provides serial keyboard, mouse general-purpose use. addition, floppy disk interface, external byte-wide expansion (EBus) EPROM, registers reset control logic integrated. Together, STP2001 STP2000 Master Controller, provide complete subsystem. serial ports keyboard/mouse general purpose compatible with AM85C30, Serial Communications Controller. serial ports fully synchronous, while keyboard/mouse ports asynchronous only. ports support data rates 38.4 Kb/s. NCR82077 floppy disk interface compatible with Intel 8077A-1 single-chip floppy controller, supporting MBit/sec transfer rate.
