概述
Description
The MPC850DEVR50BU is an Freescale/NXP development board built around the MPC850 PowerPC-based embedded processor. It’s a ready-made platform for evaluating the MPC850 core (32‑bit PowerPC) at ~50 MHz and prototyping embedded applications.
Key points
- CPU: MPC850 at 50 MHz; on-board RAM/ROM/Flash for program and data storage.
- I/O: multiple serial ports, Ethernet, USB, GPIO, and expansion connectors (exact ports depend on revision).
- Development support: comes with bootloaders, BSPs, and toolchain support; compatible with RTOS and Linux via cross-compilation.
- Use cases: hardware/software bring-up, driver development, performance characterization, and proof-of-concept embedded designs (industrial, networking, automotive, etc.).
Starting out
- Power up, connect debugging interface (JTAG/UART as appropriate), load BSP, build sample apps, and program flash or run from external memory.
Note: exact I/O and memory map vary by revision—consult the board’s user guide for specifics.

Equivalent
There isn’t a direct drop-in equivalent. MPC850DEVR50BU is from Freescale’s PowerQUICC II MPC85xx family. Similar-functionality parts include MPC8510, MPC8521, MPC8541/8544/8548, and MPC8560/MPC8572 (peripheral/package variations). For newer options with similar roles, consider MPC83xx or QorIQ lines. For exact cross-reference, use Freescale/NXP cross-reference databases.
