MPC870VR66

The MPC870VR66 is a 32-bit PowerPC-based embedded processor from Freescale (now NXP), in the MPC87xx family. It targets real-time control in industrial automation, networking, and automotive modules where one chip handles code and I/O.
Core and memory: a PowerPC RISC core with an integrated memory controller and system bus, supporting common memories (SRAM/DRAM, flash, NVRAM).
Peripherals: Ethernet interfaces, PCI/PCI‑X, USB, multiple serial ports, timers and DMA, plus on-chip boot ROM and security options (revision-dependent).
Packaging: VR66 denotes a specific package/voltage/temperature variant of the MPC870 silicon; exact features depend on revision.
Development: use Freescale/NXP toolchains (CodeWarrior or GCC cross‑compiler), JTAG debuggers, and BSPs/manuals.
Bottom line: a compact, highly integrated PowerPC‑based SoC for embedded controllers needing real‑time performance and diverse I/O. See the MPC870VR66 datasheet for exact specs.

MPC870VR66 is a Freescale/NXP 32‑bit PowerPC-based microcontroller in the MPC870 family, typically running at 66 MHz. Key features (variant dependent) include:
- 32-bit PowerPC core at 66 MHz
- On‑chip memory options plus external memory interface for Flash/ROM and RAM
- Rich peripheral set: multiple SCI/UARTs, I2C, SPI, timers, PWM, watchdog
- DMA engine and advanced interrupt controller
- GPIO with flexible pin multiplexing
- External bus/interface support for memory and peripherals
- Debug and trace support (JTAG/on-chip debug)
- Power management with low‑power modes and wakeup options
- Boot options from on‑chip flash or external memory
Notes:
- Exact feature set (interfaces like USB, Ethernet, PCI/PCI‑X) and memory/config options vary by package/stepping. For precise specs, consult the MPC870VR66 datasheet/product brief.

- Pin count: Typically 208 pins (LQFP208; other packages may exist).
- Function: 32-bit PowerPC MPC870 embedded microprocessor core with integrated peripherals (memory controller, PCI/PCI-X, Ethernet MACs, I/O) for embedded applications.

Manufacturer: Freescale Semiconductor (the embedded processing unit that originated from Motorola’s semiconductor division; now part of NXP Semiconductors).
What kind of company: A semiconductor company that designs and manufactures embedded processors, microcontrollers, and related integrated circuits for automotive, industrial, and consumer applications.

MPC870VR66 is used in:
