National Semiconductor Corp. (NSC) has introduced two IPMI 1.5-compliant baseboard management controllers (BMCs) that provide complete remote management capability for medium- and high-end servers.

The PC87435 and PC87436 single-chip BMCs support v1.5 of the Intelligent Platform Management Interface (IPMI) specification, and consist of a processor, internal sensors, internal memory, and firmware. The products monitor a server's baseboard power supply voltages, other system voltages, temperature sensors and fan indicators to provide remote status, manageability, and system error recovery.

Both devices incorporate the NSC CompactRISC CR16B core (a 16-bit RISC processor), system support functions, low pin count host interface, and a bus interface unit (BIU) that directly interfaces with optional expansion memory and I/O devices. The PC87435 also includes on-chip flash and RAM memories.

System support functions include two SMBus channels in the PC87435 (four SMBus channels in the PC87436), ADC for system control, system health monitoring and analog controls, USART for ICMB extension, Watchdog and other timers, and interrupt control and general-purpose I/O.

The PC87435 and PC87436 are packaged in 176-pin LQFPs, and are available for $12.50 and $9.50, respectively. An evaluation board for the PC87435 is available to enable rapid firmware and system development.
