Freescale SCF5250LAG100 Integrated ColdFire V2 Microprocessor

The SCF5249 microprocessor delivers a new level of performance on the popular Version 2 ColdFire core with over 125 (Dhrystone 2.1) MIPS @ 140 MHz and the lowest ever power consumption (1.3 mW/MHz) on a ColdFire device. This highly integrated microprocessor builds upon the widely used ColdFire peripheral mix by adding new audio enhancements and analog functionality, in addition to an enhanced Multiply Accumulate Unit (eMAC), large on-chip memory (96K SRAM, 8K I-Cache), and a SDRAM controller.

• Coldfire V2 processor core operating at 120MHz
• 8 KB direct mapped instruction cache
• 128 KB static random access memory (SRAM) (two 64KB banks)
• Operates from internal or external crystal oscillator
• Debug module (background and real-time)
• Two I²C modules
• Queued serial peripheral interface (QSPI) (master only)
• Digital audio transmitter (SPDIF) and two receivers for IEC958 audio protocol
• CD-ROM and CD-ROM XA block decoding and encoding function
• Two independent 16-bit timers
• Supports 16-bit wide synchronous dynamic random access memory (SDRAM)
• Two independent universal asynchronous receiver and transmitter(UARTs)
• Pulse-lock loop software watchdog)
• Four-channel direct memory access (DMA)
• Six-channel 12-bit analogue-to-digital converter (ADC)
• IDE or SmartMedia™ interface
• Flash memory card interface
• GPIO
• 1.2-volt core, 3.3-volt input/output
