NXP Semiconductors MCF5282CVF80

Overview

MCF5282CVF80 from NXP (formerly Freescale) is a 32-bit ColdFire V2 core microcontroller with integrated Fast Ethernet Controller (FEC), FlexCAN, QADC, QSPI, and I²C interfaces. It operates at 80 MHz, includes 128 KB on-chip Flash, 16 KB SRAM, and supports multiple low-power modes including Stop, Doze, and Wait. It is used in industrial networking gateways requiring deterministic real-time control and dual-protocol connectivity.

For engineers reviewing the MCF5282CVF80 datasheet, MCF5282CVF80 pinout, MCF5282CVF80 application, or MCF5282CVF80 equivalent, key selection criteria include its 80 MHz ColdFire V2 core performance, integrated FEC + FlexCAN dual-bus capability, 128 KB flash/16 KB SRAM memory partitioning, QADC resolution and sampling rate, and VFQFPN144 package thermal and routing constraints.

Technical Context

The MCF5282CVF80 implements the ColdFire V2 microarchitecture with a 5-stage pipeline, 4 KB instruction/data cache, and enhanced MAC unit supporting fractional multiply-accumulate operations. Its clock system integrates a programmable PLL with selectable input sources (crystal, external clock, or internal RC oscillator) and configurable output dividers for peripheral domain clocks.

System-level integration includes a 32-bit SDRAM controller supporting up to 256 MB, an External Interface Module (EIM) with four chip-select banks, and a System Control Module (SCM) managing bus arbitration, reset sequencing, and privilege-based memory protection via SACU registers.

FAQ

What is the maximum operating frequency of the MCF5282CVF80?

The MCF5282CVF80 operates at a maximum core frequency of 80 MHz, achieved via its integrated Phase-Locked Loop (PLL) configured from a 4–33 MHz crystal or external clock source. This frequency is validated across industrial temperature ranges (–40°C to +85°C) and defines instruction execution timing, interrupt latency, and peripheral bus bandwidth. The MCF5282CVF80's performance remains stable under full load when VDDCORE is maintained at 1.5 V ±3% with proper decoupling.

Does the MCF5282CVF80 support secure boot or flash protection?

Yes, the MCF5282CVF80 implements flash security through its ColdFire Flash Module (CFM) with dedicated registers including CFMSEC (Flash Security Register) and CFMPROT (Flash Protection Register). These allow locking flash sectors against read/write access, enabling secure boot verification and preventing unauthorized firmware extraction. Back-door access is disabled after security activation, and the MCF5282CVF80 requires a mass erase to restore unprotected operation.

How many CAN interfaces does the MCF5282CVF80 integrate?

The MCF5282CVF80 integrates two fully independent FlexCAN modules compliant with CAN 2.0B specification. Each supports 64 message objects, hardware acceptance filtering, and time-stamped transmission/reception. They operate concurrently without shared resources, allowing the MCF5282CVF80 to serve as a dual-bus bridge - for example, connecting J1939 and CANopen networks simultaneously in vehicle telematics applications.

What type of analog-to-digital converter is included in the MCF5282CVF80?

The MCF5282CVF80 includes a Queued Analog-to-Digital Converter (QADC) with 10-bit resolution, 16 input channels, and hardware-managed conversion sequencing. It supports multiple trigger sources (PIT, GPT, or software), automatic channel scanning, and configurable sample-and-hold timing. The QADC achieves 1.25 µs conversion time and integrates result FIFOs to reduce CPU polling overhead - a key feature for sensor-rich industrial control using the MCF5282CVF80.

Is the MCF5282CVF80 pin-compatible with other ColdFire family members?

No, the MCF5282CVF80 is not pin-compatible with other ColdFire devices such as the MCF5213 or MCF52235 due to differences in peripheral integration, signal multiplexing, and package-specific pin assignments. While functional overlap exists (e.g., UART, SPI, I²C), the VFQFPN144 pinout of the MCF5282CVF80 is unique to its feature set - particularly the dedicated ENET_MDC/MDIO, CAN0/CAN1 differential pairs, and EIM address/data bus layout. Board redesign is required for migration.
