VRC4372 I/O Controller

with PCI Interface

Data Sheet

February 2000

Description

The V^RC4372^TMis a PCI-based I/O controller for high-performance, low-cost system

implementation. Connected to the PCI bus, it is designed to support NEC’s V^R43xx

CPU, interfacing between the V^RC4373^TMor V^RC4375^TMsystem controller and

peripherals for tethered applications such as set-top boxes, printers, network

computers and consumer electronics.

Features

Compatible with NEC V^R43xx CPUs and V^RC4373 and V^RC4375 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 Por t

•

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

NEC V^RCchipsets are designed for use with NEC V Series microprocessors. NEC makes no claim

as to the suitability of V^RCchipsets for use with non-NEC microprocessors and does not warrant

their performance, suitability or use in such applications.
