1 / 134 page  VSC056 Data Sheet Enhanced Two-Wire Serial Backplane Controller Revision 4.1 January 2008 For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. Maxim Integrated Products 1 of 134 To order the VSC056 device, see “Ordering Information,” page 134. GENERAL DESCRIPTION The VSC056 device is an I/O-intensive peripheral device that is intended to be part of a cost-effective Fibre Channel Arbitrated Loop (FC-AL), Small Computer System Interface (SCSI), Serial Attached SCSI (SAS), or Serial ATA (SATA) enclosure management solution. The device contains an address-programmable two-wire serial interface, a block of control and status registers, I/O port control logic, specialized port bypass control logic, and a clock- generation block. Along with an external crystal, the device can be configured to support up to 64 bits of general-purpose I/O; or 16 bits of general-purpose I/O, 32 bits of port bypass control (16 pairs supporting 16 drives), eight fan speed monitoring inputs, and eight pulse-width modulated general-purpose control outputs. The VSC056 supports various combinations of individual port bypass circuit (PBC), clock recovery unit (CRU), and signal detect unit (SDU) functions, as well as integrated solutions. The control register portion of the device allows the user to individually program each I/O pin as an input, an output, or an open-drain or open-source output. FEATURES • Up to 64 bits of user-definable, bidirectional general-purpose inputs and outputs • Integrated port bypass, clock recovery and signal detect support for up to 16 drives • Eight programmable fan speed monitoring inputs • Eight programmable pulse-width modulated fan control outputs • Up to 32 programmable input-to-output bypass pairs • Two clock input ranges: 8.0 MHz to 12.5 MHz (external crystal or external clock source) and 32.0 MHz to 75.0 MHz (external clock source) • Selectable direct LED drive flashing capability • Pin-programmable addressing for up to 16 devices on a single serial bus • 5-V tolerant high current I/O, Slave mode two-wire serial interface and interrupt output • Ten programmable LED pulse train circuits • One 24-bit general-purpose timer (supports a timeout greater than four seconds with a 12.5 MHz core clock) • Up to 16 subaddressed Master mode two-wire serial interface ports • External reset of the slave two-wire serial core • Enhanced fan speed monitor input filters • 20% of package pins are power and ground for excellent noise immunity and long-term reliability APPLICATIONS • Enterprise storage environments • Storage Area Network (SAN) appliances • Network Attached Storage (NAS) systems • Fabric Attached Storage (FAS) systems • Rack-mounted servers with RAID • JBOD arrays • Disk-based backup storage • Near-line storage replacement systems • Fixed-content storage systems |
