MPC8555EVTAPF

The MPC8555EVTAPF is Freescale/NXP’s evaluation board for the MPC8555E PowerQUICC II Pro embedded processor. It’s designed to help developers prototype and validate software and hardware for PowerPC-based networking applications.
Key points:
- CPU/memory: MPC8555E core with onboard flash and DRAM options.
- I/O: typical PowerQUICC II Pro interfaces (Ethernet, PCI/PCI-X, USB, serial/JTAG) and expansion headers.
- Boot and debug: onboard boot ROM/Flash options, JTAG and serial console for debugging.
- Software: vendor BSPs for Linux and RTOSs (e.g., VxWorks, QNX).
Typical use: evaluation of networked embedded systems such as appliances and gateways, requiring multiple interfaces and real-time performance.
Note: exact features vary by revision; consult the MPC8555EVTAPF user guide for precise specs and pinouts.

Direct equivalents aren’t available outside the MPC85xx family. The closest pin/feature-compatible options are other MPC85xx PowerQUICC II Pro devices, e.g., MPC8555, MPC8554E, and MPC8560. For exact compatibility (pinout, peripherals, memory map), use the Freescale/NXP Product Selector to compare parts.

Here are the typical features of the MPC8555EVTAPF evaluation board (MPC8555 PowerQUICC III Pro):
- CPU: Freescale/NXP MPC8555 PowerPC 32-bit core (PowerQUICC III Pro family).
- Clock: On-board clocking for CPU up to about 1 GHz (board specific).
- Memory: On-board DDR2 SDRAM with flash memory; expansion options available.
- High-speed interfaces: PCI-X and PCI expansion options; integrated Ethernet MACs for network connectivity.
- Ethernet: Support for standard Ethernet connectivity (10/100/1000 Mbps as implemented on the board).
- USB: USB 2.0 host/device functionality.
- Serial/IO: Multiple UARTs, I2C, SPI for peripheral communication; GPIO for general I/O.
- DMA and peripherals: DMA engine, timers, watchdog, and other common PPC peripherals.
- Debug/Development: JTAG (IEEE 1149.1) for in-circuit debugging; serial console.
- Boot/OS support: Linux, VxWorks, and other PPC RTOS support on supported toolchains.
- Expansion and ruggedness: On-board expansion headers, carrier/slot interfaces; industrial temperature range.
Note: Exact counts and speeds may vary by board revision.

Pin count: Depends on the package; MPC8555EVTAPF is the EVT (evaluation) high-pin-count BGA variant, so exact pin count must be taken from the datasheet for the EVTAPF package.
Function: MPC8555E is a PowerQUICC III embedded communications processor (PowerPC core) with integrated peripherals (Ethernet MACs, PCI/PCIe, memory controllers, etc.). For the exact pin count, refer to the MPC8555E EVTAPF package documentation.

- Manufacturer: Freescale Semiconductor, Inc. (now part of NXP Semiconductors).
