It operates at up to 200 MHz core frequency (308 MIPS), supports DDR/SDR SDRAM up to 1 GB, and features PCI 2.2, FlexBus, USB 2.0 Device, two FlexCAN 2.0B controllers, and optional cryptography acceleration - deployed in industrial networking gateways and real-time embedded control systems.

For engineers reviewing the MCF5485CVR200 datasheet, MCF5485CVR200 pinout, MCF5485CVR200 application, or MCF5485CVR200 equivalent, key selection considerations include its 388-pin TEPBGA package, 1.5V core / 2.5V DDR / 3.3V I/O voltage domains, ColdFire V4e ISA compatibility, integrated memory controller timing constraints, and support for real-time OS environments requiring MMU-based virtual memory management.

Technical Context

The MCF5485CVR200 implements a limited-superscalar ColdFire V4e core with Harvard architecture, 32-Kbyte instruction and data caches, and IEEE-754-compliant double-precision FPU. Its system integration unit includes an XLB bus arbiter, interrupt controller, watchdog timer, four 32-bit general-purpose timers with PWM capability, and two slice timers.

Peripheral subsystems include a 32-bit DDR/SDR SDRAM controller (66–133 MHz), PCI 2.2 interface (33–66 MHz), FlexBus (33–66 MHz, six chip-selects), dual FEC Ethernet MACs with 2-Kbyte FIFOs each, USB 2.0 device controller with integrated PHY, four PSCs supporting UART/USART/IrDA, I²C, two FlexCAN 2.0B controllers (16 message buffers each), DSPI, and optional crypto accelerator for DES/3DES, AES, RC4, MD5/SHA-1/SHA-256, and RNG.

FAQ

What is the maximum supported DDR SDRAM speed for the MCF5485CVR200?

The MCF5485CVR200 DDR SDRAM controller supports operation up to 133 MHz, enabling peak bandwidth of 1.06 GB/s in double-data-rate mode. It is compatible with standard DDR SDRAM components meeting JEDEC specification JESD79, and requires proper termination, SSTL_2 I/O drive strength configuration, and adherence to tRCD, tRP, and tRC timing parameters as defined in the MCF5485EC datasheet Section 9.2.

Does the MCF5485CVR200 support Linux operating systems?

Yes, the MCF5485CVR200 supports Linux via its integrated Memory Management Unit (MMU), 32-Kbyte instruction and data caches, and ColdFire V4e architecture compatibility with GNU toolchains. Community-supported BSPs (e.g., Timesys LinuxLink, earlier Freescale MQX/Linux ports) provide kernel 2.6.x support, though active vendor maintenance ended with NXP's transition to i.MX series. The MCF5485CVR200 remains viable for long-lifecycle Linux deployments where hardware stability is prioritized over new kernel features.

What are the power supply sequencing requirements for the MCF5485CVR200?

The MCF5485CVR200 requires strict voltage sequencing: IVDD/PLLVDD and EVDD/SDVDD must ramp together up to 0.9 V, then separate to final values (1.5 V and 3.3 V/2.5 V respectively), with IVDD never exceeding EVDD or SDVDD by more than 0.4 V. Rise times must be slower than 1 µs to prevent ESD diode conduction. Power-down follows the reverse order: IVDD/PLLVDD must fall to 0 V before EVDD/SDVDD. These constraints are documented in Freescale Application Note AN3349 and MCF5485EC Section 4.2.

Is the USB 2.0 interface on the MCF5485CVR200 a device-only or OTG-capable controller?

The MCF5485CVR200 integrates a USB 2.0 Device Controller only - it does not support USB On-The-Go (OTG) or Host mode. It implements the USB 2.0 specification as a peripheral device with one control endpoint and six configurable endpoints (interrupt, bulk, isochronous), 4-KB shared endpoint FIFO RAM, and a fully integrated physical layer (PHY). External USB host functionality requires companion ICs or alternate processors such as the i.MX series.

How many CAN interfaces does the MCF5485CVR200 include, and what version do they support?

The MCF5485CVR200 includes two independent FlexCAN controllers compliant with CAN 2.0B specification (ISO 11898-1), each supporting 16 message buffers, programmable bit timing, and hardware acceptance filtering. Both controllers operate concurrently and support standard and extended frame formats, error confinement, and loopback self-test modes - commonly used in industrial automation and vehicle subsystems requiring redundant or multi-bus CAN communication.
