The Pm8540 is a ProcessorPMC protocol and packet processing engine for telecom infrastructure applications. Based on Freescale's MPC8540 PowerQUICC III communications processor, the board gives telecom OEMs a simple way to add protocol processing and system management capability to telecom systems equipped with PMC or PTMC (PCI Telephony Mezzanine Card) expansion slots.
Developed by Artesyn Communication Products, a division of Artesyn Technologies, the Pm8540 features two Gigabit 10/100/1000Base-T Ethernet ports, which are routed to the PMC connector, and one 10/100Base-TX Ethernet port, which is routed to the module's front bezel. The Pm8540 also features up to 512 Mbytes of SDRAM, 32 Mbytes of flash memory, an I2 C bus system management controller, and a four-channel DMA controller, which boosts overall performance by facilitating high-speed data movement between module resources without CPU intervention.
The MPC8540 processor provides the compute and protocol acceleration engine for the Pm8540. The Pm8540's mezzanine interface complies with IEEE 1386.1 (PMC), and provides a subset of the PICMG 2.15 PTMC Configuration 2 features. The module operates from a 3.3- or 5-V supply, and consumes 11.5 W typical. Software support includes Carrier Grade Linux. The Pm8540 sells in OEM quantity for $759.
