The Emerson/Motorola PPMC750-1241 is a single-wide PCI Mezzanine Card (PMC) processor module built around the PowerPC 750 microprocessor running at 350 MHz. Leveraging Motorola PowerPlus II architecture, it delivers 32-bit processing with a 64-bit PCI host bridge operating at 33 MHz, making it suited for embedded systems where size and performance must coexist. The module integrates 64 MB of ECC SDRAM, 1 MB L2 backside cache, 8 MB Flash memory, and a 144-bit ECC memory controller ASIC to ensure data integrity in mission-critical applications.
