FAQ

What is the maximum operating frequency of the MCF5282CVF80J?

The MCF5282CVF80J operates at a maximum core frequency of 80 MHz, achieved using an internal Phase-Locked Loop (PLL) that multiplies an external crystal or oscillator input. This frequency enables real-time execution of Ethernet and CAN protocol stacks while maintaining margin for application code. The MCF5282CVF80J's timing specifications are validated across industrial temperature ranges (–40°C to +85°C) per its qualification data.

Does the MCF5282CVF80J include on-chip Flash and SRAM memory?

Yes, the MCF5282CVF80J integrates 256 KB of on-chip Flash memory and 32 KB of on-chip SRAM. The Flash supports secure programming, sector protection, and erase/program cycles rated for 100,000 cycles. The SRAM retains data during low-power Stop mode and is accessible by both CPU and DMA controllers. These memory resources are mapped into the ColdFire V2 linear address space and configured via dedicated base address registers (FLASHBAR and RAMBAR).

What communication interfaces does the MCF5282CVF80J support?

The MCF5282CVF80J supports Fast Ethernet (FEC) with MII/RMII PHY interface, two FlexCAN 2.0B controllers, three UART modules (with IrDA support), an I²C bus module, a queued SPI (QSPI), and a queued ADC (QADC). It also includes a JTAG debug interface compliant with IEEE 1149.1. These interfaces allow the MCF5282CVF80J to serve as a central hub in multi-protocol embedded systems without requiring external bridge ICs.

Is the MCF5282CVF80J pin-compatible with other ColdFire microcontrollers?

No, the MCF5282CVF80J is not pin-compatible with earlier ColdFire families such as MCF5206 or MCF5272. It uses a dedicated 144-pin LQFP package with signal assignments optimized for its integrated FEC and FlexCAN peripherals. Migration from other ColdFire variants requires PCB redesign due to differences in power sequencing, clock routing, and peripheral pin mapping-even within the MCF528x series, package variants (e.g., MCF5282CVF66 vs. MCF5282CVF80J) share footprint but differ in speed-grade validation and thermal characteristics.

What development tools are supported for the MCF5282CVF80J?

The MCF5282CVF80J is supported by NXP's CodeWarrior Development Studio for ColdFire v10.x, which includes C/C++ compiler, debugger, and real-time OS (RTOS) integration. Third-party tools like IAR Embedded Workbench for ColdFire and GNU GCC-based toolchains (e.g., ColdFire GNU Tools) also provide full register-level access and debugging via JTAG/BDM. Evaluation boards such as the M5282EVB reference design include on-board Ethernet PHY, CAN transceivers, and expansion headers compatible with the MCF5282CVF80J's pinout.
