Technical Specifications

Due to the age of this part number, detailed specifications are difficult to obtain. However, similar Freescale/NXP communication processors typically operate at clock speeds ranging from hundreds of MHz to over 1 GHz. They usually support various memory types, including DDR SDRAM and NOR flash. They provide multiple communication interfaces, such as Gigabit Ethernet, UARTs, SPI, and I2C. The specific power consumption varies depending on the operating conditions and workload. The package type is likely a BGA (Ball Grid Array) for high pin count and surface mount assembly. Datasheet is required to determine the process node and details of the core, memory and peripheral configuration. Note that due to obsolescence, sourcing this part might be problematic.
