1 / 30 page ADVANCE INFORMATION COPYRIGHT © INTEL CORPORATION, 1997 November 1997 Order Number: 273108-002 8 x931AA/8x931HA UNIVERSAL SERIAL BUS PERIPHERAL CONTROLLERS s 8x931AA Hubless USB Peripheral Controller s On-chip USB Transceivers s On-chip Phase-locked loop s FIFO Data Buffers — Two Pairs of 8-byte Transmit and Receive FIFOs — One Pair of 16-byte Transmit and Receive FIFOs — Supports Isochronous and Non-isochronous Data s Automatic FIFO Management s Three USB Interrupt Vectors — Endpoint Transmit/Receive Done — Start of Frame — Global Suspend/Resume/USB Reset s Regulated 3V Output for Root Port Pullup Resistor s On-chip ROM Options — 0 or 8 Kbytes s 256 bytes On-chip Data RAM s Four Input/Output Ports s MCS® 51 UART s Three 16-bit Timer/Counters s Keyboard Control Interface s Four Dedicated LED Driver Outputs s 6- or 12-MHz Crystal Operation — Low Clock Mode (3MHz) s 8x931HA Includes all 8x931AA Features s 8x931HA USB Hub has One Internal Downstream, and Four External Downstream Ports — Universal Serial Bus Specification 1.0 Compliant — Serves as both USB Hub and USB Embedded Function (Internal Port) s USB Hub — Connectivity Management — Downstream Device Connect/Disconnect Detection — Power Management, Including Suspend and Resume — Bus Fault Detection and Recovery — Full and Low Speed Downstream Device Support s Hub Endpoint Done Interrupt s Output Pin for Port Power Switching s Input Pin for Overcurrent Detection s Hub FIFO Data Buffers — One Pair of 8-byte Transmit and Receive FIFOs — One 1-byte Transmit Register s Embedded Function FIFO Data Buffers — Same as the 8 x931AA s 12-MHz Crystal Operation — Low Clock Mode (3MHz) The 8 x931AA and 8x931HA USB peripheral controllers are based on the MCS®51 microcontroller. They consist of standard 8XC51Fx peripherals plus a USB module. The 8 x931HA USB module provides both USB hub and USB embedded function capabilities. The 8 x931HA supports USB hub functionality, embedded function, suspend/resume modes, isochronous/non-isochronous transfers, and is USB rev 1.0 specification compliant. The USB module contains one internal and 4 external downstream ports and integrates the USB transceivers, serial bus interface engine (SIE), hub interface unit (HIU), function interface unit (FIU), and transmit/receive FIFOs. The 8 x931AA is a hubless USB peripheral controller which contains the same feature set as the 8 x931HA hub controller except for the hub module. The 8x931AA/HA uses the standard instruction set of the MCS 51 architecture. |
