Infineon Technologies MB86613SPFV-G-BND

Overview

MB86613SPFV-G-BND from Fujitsu is an IEEE 1394 Open Host Controller Interface (OHCI) controller LSI integrating PHY and LINK layers, PCI 2.2 interface, and 13-channel ContextProgram DMA engine. It supports S100/S200/S400 data rates, operates on dual supplies (+5V/+3.3V for PCI/DMA, +3.3V for 1394), and delivers 33 MHz PCI timing with on-chip 6 KB FIFO and 2048-byte OHCI register set for digital video capture systems.

For engineers reviewing the MB86613SPFV-G-BND datasheet, MB86613SPFV-G-BND pinout, MB86613SPFV-G-BND application, or MB86613SPFV-G-BND equivalent, key selection criteria include IEEE 1394-1995/P1394a compliance, integrated PHY+LINK, 13-channel OHCI DMA allocation, 32-bit 33 MHz PCI bus master capability, and dual-voltage power domain partitioning for host-side FireWire interface design.

Technical Context

The device implements a full OHCI-compliant host controller architecture with three functional domains: PCI interface (32-bit, 33 MHz, 5V/3.3V tolerant), 1394 physical layer (integrated transceiver, comparator, 400 MHz PLL for PHY, 50 MHz for Link core), and ContextProgram DMA subsystem (13 independent channels, 6 KB segmented FIFO, 128B × 3 work memory).

It embeds dedicated hardware blocks including Open HCI register set (2048 B), bus manager CSRs for cycle timer and interrupt control, serial ROM interface for PCI configuration, and PHY Request Unit (PRU) for automatic physical-layer request packet decoding - all coordinated via shared system memory-mapped OHCI context descriptors.

Key Specifications

Pinout & Package

MB86613SPFV-G-BND is housed in a 100-pin plastic LQFP package with defined power domains: VDD5/VSS5 (5V/3.3V PCI I/O), DVDD3/DVSS3 (3.3V digital core), AVDD3/AVSS3 (3.3V analog PLL/transceiver), and dedicated 1394 differential pairs (TPA/TPA#, TPB/TPB#) with bias and cable power sensing pins.

FAQ

What power supply voltages does MB86613SPFV-G-BND require?

MB86613SPFV-G-BND requires three distinct voltage domains: +5V or +3.3V for PCI I/O buffers (VDD5/VSS5), +3.3V for digital core logic including OHCI and DMA (DVDD3/DVSS3), and +3.3V for analog PLL and 1394 transceiver circuits (AVDD3/AVSS3). These must be independently regulated and decoupled per the datasheet layout guidelines.

Does MB86613SPFV-G-BND support IEEE 1394b (FireWire 800)?

No. MB86613SPFV-G-BND implements only IEEE 1394a (P1394a draft 2.0) and IEEE 1394-1995 specifications, supporting S100, S200, and S400 data rates over beta-style 6-pin or 4-pin cables. It lacks the physical layer circuitry, encoding scheme, and arbitration logic required for 1394b's 800 Mbps mode or CAT5 cabling.

How many isochronous channels can MB86613SPFV-G-BND manage simultaneously?

The device supports up to four independent isochronous transmit channels and four isochronous receive channels, allocated among its 13 total ContextProgram controllers. This allows concurrent streaming from multiple sources (e.g., two DV cameras and two audio devices) while maintaining guaranteed bandwidth and cycle-synchronized timing via the on-chip bus manager.

Is MB86613SPFV-G-BND compatible with modern x86-64 operating systems?

Yes, but through legacy driver support. Windows XP/Vista included native OHCI drivers; Linux kernels 2.4+ provide firewire-ohci module support. Modern Windows 10/11 and recent Linux distributions retain backward-compatible OHCI stack implementations, though users must verify driver signing and secure boot compatibility for deployment in certified environments.
