UPD31172 Datasheet Mos Integrated Circuit

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD31172 VRC4172 TM PANION CHIP FOR VR4121.

General Description

The µPD31172 (mercial name: VRC4172) is a panion chip designed for NEC’s µPD30121 microprocessor (mercial name: VR4121).

The VRC4172 has the following functions available on chip: a USB host controller, an IEEE1284 parallel controller, a 16550 serial controller, a PS/2 controller, general-purpose ports (GPIO), programmable chip select (PCS), and a PWM controller (a duty modulated light pulse generation function for LCD backlighting).

The VRC4172 can be directly connected to the VR4121, allowing a reduction in the man-hours required for development of a Windows™ CE system.

Key Features

  • Directly connectable to VR4121.
  • On-chip USB host controller.
  • USB ports: 2.
  • Compliant with the USB OpenHCI specifications, release 1.0.
  • Communicates with USB device asynchronously with host CPU.
  • Full-speed (12 Mbps) and low-speed (1.5 Mbps) modes supported.
  • System clock: 48 MHz.
  • On-chip PS/2 controller.
  • On-chip IEEE1284 parallel controller.
  • On-chip 16550 serial controller.
  • General-purpose ports (GP.
