DATA SHEET
D
The STP2001Slave I/O Controller is a highly integrated, low-cost, low-power device designed for use in single-processor
systems with an SBus interface. The STP2001 provides serial I/O for keyboard, mouse and general-purpose use. In addi-
tion, a floppy disk interface, an external byte-wide expansion bus (EBus) for TOD and EPROM, I/O registers and reset
control logic are integrated. Together, the STP2001 and the STP2000 Master I/O Controller, provide a complete I/O
subsystem.
The two serial ports for keyboard/mouse and general purpose use are compatible with the AMD AM85C30, rev C Serial
Communications Controller. The TTY A/B serial ports are fully synchronous, while the keyboard/mouse ports are asyn-
chronous only. All ports support data rates up to 38.4 Kb/s. The NCR82077 floppy disk interface is compatible with the
Intel 8077A-1 single-chip floppy controller, supporting up to a 1 MBit/sec transfer rate.
Features
• Integrates two dual serial controllers, a high-speed
• Directly interfaces to CPU through the SBus
• Auxiliary I/O registers (used for LED, floppy and
• Interrupt Controller for single-processor SBus
• System reset control
• Counter/timers for single-processor SBus system
• EBus interface
• JTAG internal and boundary SCAN logic
• 160-pin PQFP packaging
• IC is also available from NCR Corp. (PN -
