Field Programmable Gate Array; Baseboard Management Controller; Scsi Controller; Ide Interface - HP Integrity rx1620 Operation Manual

Features include:
• Data rates up to 115.2kbps
• 16550A fully compatible controller
• A 16-byte transmit FIFO to reduce the bandwidth requirement of the external CPU
• A 16-byte receive FIFO with four selectable interrupt trigger levels and error flags to reduce
the bandwidth requirement of the external CPU
• UART control that provides independent transmit and receive
• Modem control signals (-CTS, -RTS, -DSR, -DTR, -RI, -CD, and software controllable line
break)
• Programmable character lengths (5, 6, 7, 8) with Even, Odd or No Parity
• A status report register

Field Programmable Gate Array

The field programmable gate array (FPGA) provides ACPI and low pin count (LPC) support for
HP Intel Itanium 2 platforms based on HP chipsets. This controller is connected to the PDH bus
and provides these features:
• ACPI 2.0 interface
• LPC bus interface to support BMC
• Decoding logic for PDH devices

Baseboard Management Controller

The baseboard management controller supports the industry-standard Intelligent Platform
Management Interface (IPMI) specification. This specification describes the management features
that have been built into the system board. These features include: diagnostics (both local and
remote) console support, configuration management, hardware management, and troubleshooting.
The baseboard management controller provides the following:
• Compliance with Intelligent Platform Management Interface 1.0
• Tachometer inputs for fan speed monitoring
• Pulse width modulator outputs for fan speed control
• Push-button inputs for front panel buttons and switches
• One serial port, multiplexed with the system console port
• Remote access and intelligent chassis management bus (ICMB) support
• Three I2C master/slave ports (one the ports is used for IPMB)
• Low pin count (LPC) bus provides access to three keyboard controller style (KCS) and
one-block transfer (BT) interface
• 32-bit ARM7 RISC processor
• 160-pin low profile flat pack (LQFP) package
• Firmware is provided for the following interfaces:
• Intelligent platform management interface (IPMI)
• Intelligent platform management bus (IPMB)

SCSI Controller

The SCSI controller is an LSI Logic 53C1030 chip. This chip is fully compliant with the SCSI
Peripheral Interface-4 Specification (SPI-4). It has two independent SCSI channels supporting
devices at speeds up to 320 MB/sec. each. The 53C1030 adheres to the PCI-X addendum to the
PCI Local Specification and is hard-wired to PCI ID 1 which corresponds to bit 17 of the PCI AD
bus.

IDE Interface

The IDE interface provides support for an internal CD-RW or a DVD reader through an internal
IDE connector and cable. This interface supports the master capability.
