Description



Features:

· Compatible with NEC VR43xx CPUs and VRC4373 and VRC4375 system controllers
· PCI Bus Interface Controller
    • Compliant with the 3.3-volt PCI interface specification (version 2.1)
    • 5-volt PCI signaling in a controlled environment (with voltage spikes less than 7.6 volts and DC levels less than 6.6 volts)
    • PCI bus arbitration for one internal and six external PCI masters
· I/O Controller
    • ISA-like, 16-bit I/O bus and four independent direct memory access (DMA) channels
    • Ten chip selects and control signals for interfacing to external peripheral chips
    • N-to-3 interrupt controller to regulate interrupts from 14 input pins, two internal timers, the keyboard, the mouse, and four DMA channels can be encoded onto one of three outgoing interrupt lines
· Four programmable DMA channels
    • Unique TC, EOP, DREQ, and DACK signals on each channel
    • Block or single transfers
    • Read or write requests
    • I/O device-demanded service requests via DREQx
    • Software-initiated requests
    • Channel suspend via the MASK register bit
    • I/O device transfer termination via EOP
    • Channel reload notification and termination notification via an interrupt
    • Efficient PCI bus data packing mode
    • Byte/short scattering/gathering capabilities (one per PCI word)
· Miscellaneous I/O
    • Timer and a beeper source
    • General-purpose control/status I/O pins
· Test Port
    • TESTOE signal that can be used to tristate all outputs
    • SCAN pin to place the chip in scan mode
· Data buffers for direct memory access channels and the I/O bus
· 33-MHz bus frequency
