FAQ

What is the maximum operating frequency of the MCF52258CVN66J?

The MCF52258CVN66J is rated for a maximum core clock frequency of 66 MHz, delivering 63 MIPS (Dhrystone 2.1) performance. This frequency is achieved using the on-chip PLL with external crystal or internal relaxation oscillator input. The device supports multiple clock modes including stop, wait, and doze states to optimize power consumption without compromising real-time responsiveness in the MCF52258CVN66J.

Does the MCF52258CVN66J support USB On-The-Go functionality?

Yes, the MCF52258CVN66J integrates a full USB OTG dual-mode controller compliant with USB 1.1 and 2.0 specifications. It supports both host and device roles, 16 bidirectional endpoints, and DMA/FIFO data transfer interfaces. The MCF52258CVN66J requires only external series resistors and ESD protection on the DP/DM lines - no external transceiver is needed for full-speed operation.

Is the Mini-FlexBus interface available on the MCF52258CVN66J?

Yes, the Mini-FlexBus external bus interface is available on the MCF52258CVN66J in its 144-pin LQFP package. It supports non-multiplexed 8-bit data/20-bit address operation up to 40 MHz bus clock, with two chip selects and programmable wait states. This allows glueless interfacing to NOR flash, SRAM, or FPGA devices - a capability not present in smaller-package variants of the MCF52258CVN66J family.

What cryptographic functions does the CAU in the MCF52258CVN66J accelerate?

The Cryptographic Acceleration Unit (CAU) in the MCF52258CVN66J hardware-accelerates DES, 3DES, AES (128/192/256-bit), MD5, and SHA-1 algorithms. It operates as a tightly coupled coprocessor to the ColdFire V2 core, reducing software execution time for encryption and hashing by orders of magnitude - critical for secure boot, firmware signing, and TLS session establishment in the MCF52258CVN66J.

How many analog input channels does the MCF52258CVN66J ADC support?

The MCF52258CVN66J features an 8-channel 12-bit analog-to-digital converter with simultaneous sampling capability on two channels. It supports single-scan, continuous, or triggered conversion modes, with optional interrupts on completion, zero-crossing, or out-of-range conditions. Unused ADC inputs can be reconfigured as GPIO, making the MCF52258CVN66J suitable for mixed-signal applications requiring both precision sensing and flexible I/O.
