MPC8347VVALFB

Introduction to MPC8347VVALFB
- What it is: A Freescale/NXP PowerQUICC II Pro single-chip embedded processor in the MPC83xx family, widely used in networking gear (routers, switches, gateways).
- Core: PowerPC-based e300 32-bit CPU core, designed for high-throughput embedded tasks with on-chip caches.
- Peripherals: dual Ethernet MACs (10/100/1000 Mbps), PCI/PCI-X, USB, multiple serial interfaces, on-chip DMA, timers, and memory controllers.
- Memory/I/O: integrated memory controller for DDR SDRAM/Flash and high-speed buses to off-chip memory and peripherals; cryptography/security engine in many configurations.
- Packaging/variant: VVALFB denotes a specific package/temperature/lead-free variant (industrial/extended temperature options vary by part).
- Use cases: suitable for embedded networking equipment, telecom appliances, and edge devices; widely supported by Linux, VxWorks, and Freescale/NXP BSPs.
If you need exact specs (MHz, memory sizes, number of MACs), please specify the datasheet revision or your board variant.
