The Emerson PMPPC440 (or PmPPC440) is an embedded computing module PCI Mezzanine Card (PPMC) based on the IBM PowerPC® 440GP Embedded Processor. It functions as a complete, low-power, processor subsystem that can operate in both PPMC Monarch and non-Monarch modes. The PmPPC440 supports various memory configurations, user flash memory, up to two serial ports, two 10/100BaseTX Ethernet ports, and an optional Development Mezzanine Card (DMC). Some typical applications for the PmPPC440 include protocol processing, packet processing, data filtering, and I/O management It functions as a powerful, compact system-on-module (SOM) designed primarily for industrial, networking, and military embedded systems. The PMPPC440 is commonly used as a compute board, router, or protocol converter in harsh environments. Because of its PMC form factor, it is often installed on VMEbus boards, allowing designers to add processing power to legacy or proprietary backplane architectures without taking up extra physical slots.
I2C Interfaces
The PmPPC440 has an Inter-Integrated Circuit (I2C) bus controlled by the PPC440GP CPU. One I2C interface provides software access to the SO-DIMM, the real-time clock (RTC), a 64-kilobit serial EEPROM for nonvolatile memory (NVRAM), and a two-kilobit serial configuration EEPROM for the CPU. A second I2C interface allows for external access via the P14 PMC connector.
Serial I/O
The PPC440GP CPU provides two asynchronous serial ports, which support EIA-232 signal levels. Dual serial ports can be routed to the P14 PMC connector, or a single serial port can be routed to the front panel mini-B Universal Serial Bus (USB) connector.
Ethernet
The PPC440GP CPU provides Media Access Control (MAC) functionality for two 10/100BaseTX Ethernet ports, which can automatically detect the interface speed. Optionally, two ports can be routed to the front panel RJ45 connectors (isolated) or the P14 PMC connector (non-isolated).
CPLD
The PmPPC440 uses a complex programmable logic device (CPLD) to provide many logic functions, including LED control, configuration registers, reset and chip select control, and the DMC interface.
PCI/PCI-X Bus
The PmPPC440 supports a Peripheral Component Interconnect (PCI) / PCI-X bus that can operate at 33/66/133 MHz with a 32- or 64-bit data path. The PmPPC440 can function as a local PCI host (Monarch) or as a peripheral (non-Monarch).
DMC
The Development Mezzanine Card (DMC) is a custom, optional, plug-on card that mounts on the back of the PmPPC440. This card facilitates hardware and software development.
The PmPPC440 uses an IBM PPC440GP central processing unit (CPU), which has a 32-bit reduced instruction set computer (RISC) embedded processor. The processor runs at 400MHz and features debug facilities, timer facilities, and 32-kilobyte instruction and data caches. The PPC440GP has a 128-bit processor local bus (PLB), a 32-bit on-chip peripheral bus (OPB), a 32-bit device control register (DCR) bus.
