PC87435

The National Semiconductor PC87435 is a highlyintegrated Enhanced IPMI Baseboard Management Controller (BMC), or satellite management controller, with an embedded RISC core and advanced functions. It is targeted for a wide range of host-independent controlled platforms such as servers and desktops.

The PC87435 incorporates National's CompactRISC® CR16B core (a high-performance 16-bit RISC processor), on-chip flash and RAM memories, system support functions, Low Pin Count (LPC) host interface and a Bus Interface Unit (BIU) that directly interfaces with optional expansion memory and I/O devices. System support functions include: two SMBus® channels; high-accuracy analog-to-digital (ADC) for system control, system health monitoring and analog controls, USART for ICMB extension, Watchdog and other timers; interrupt control and general-purpose I/O (GPIO).

The PC87435 interfaces with the host via an LPC bus that provides three interface channels, with peripherals and IPMI devices via two independent SMBuses and with additional memory and I/O ports via a private expansion bus.

The PC87435, like all members of National's AdvancedI/O family, is PC01 and ACPI compliant.
