MPC8347VVALFB

The MPC8347VVALFB is Freescale/NXP’s PowerQUICC II Pro embedded processor (SoC) for high‑performance networking devices. It centers on a 32‑bit PowerPC core with on‑chip caches and MMU, and combines this with a rich set of integrated networking peripherals and memory interfaces, making it suitable for routers, switches, gateways, and telecom equipment.
Key points:
- 32‑bit PowerPC core with caches and MMU; integrated peripherals for networking.
- Multiple Ethernet capabilities plus PCI/PCI‑X, USB, serial, SPI, I2C, and GPIO.
- External memory interfaces (SDRAM/Flash) and boot ROM.
- Packaging/variant denoted by VVALFB; check datasheet for exact pinout, voltage, and temperature grade.
- Software support includes Linux, VxWorks, and other RTOS; toolchains such as CodeWarrior or GCC.
- Used in embedded networking and telecom applications.
Note: For exact specs (clock speed, port counts, memory sizes), refer to the MPC8347 datasheet and user guide.

- Pin count: 856 pins in an FBGA package.
- Function: A PowerQUICC III embedded communications processor (MPC83xx family) with a PowerPC core, designed for networking applications; includes multiple Ethernet MACs, PCI/PCI-X interfaces, memory controllers, and other peripheral interfaces.

- Manufacturer: Freescale Semiconductor (now part of NXP Semiconductors).
- What kind of company: A multinational semiconductor company that designs and manufactures embedded processors, microcontrollers, and related integrated circuits used in automotive, networking, consumer electronics, and industrial applications. It originated from Motorola’s semiconductor division.
