Product details
Overview
MFR4200MAE40R from NXP Semiconductors (formerly Freescale) is a FlexRay communication controller IC designed for automotive high-integrity real-time networks. It integrates dual-output voltage regulation (3.3 V core + 2.5 V oscillator), on-chip clock generation, reset management, and a full FlexRay protocol engine supporting static/dynamic slot scheduling, clock synchronization, and bus guardian functionality. It operates in automotive-grade temperature range (–40 °C to +125 °C) and interfaces via asynchronous memory or HCS12 host buses.
For engineers reviewing the MFR4200MAE40R datasheet, MFR4200MAE40R pinout, MFR4200MAE40R application, or MFR4200MAE40R equivalent, this page delivers verified technical context, package-validated pin functions, FlexRay-specific timing parameters, host interface compatibility details, and confirmed automotive subsystem integration use cases - all grounded in the official Rev. 1 (Dec. 2006) datasheet and Freescale's MFR4200 Protocol Implementation Document.
Technical Context
The MFR4200MAE40R implements the FlexRay v2.1 protocol stack in hardware, including symbol encoding/decoding, frame assembly/disassembly, and time-triggered MAC layer logic with cold-start capability. Its internal clock synchronization engine supports drift damping, external offset/rate correction, and microtick-based timing resolution down to 1 µs.
It features two independent host interfaces: an 8-/16-bit asynchronous memory-mapped bus and an HCS12-compatible synchronous interface. The integrated dual-output regulator supplies VDD (3.3 V ±5 %, 200 mA) and VDDOSC (2.5 V ±5 %, 50 mA) with POR and LVR supervision, eliminating need for external regulators in compliant designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protocol Support | FlexRay v2.1 compliant - handles static/dynamic frames, sync frames, startup sequences, and bus guardian schedule monitoring per ISO 17458-4. |
| Host Interface | Configurable 8-/16-bit asynchronous memory interface or HCS12-compatible synchronous interface - enables direct connection to MCUs without glue logic. |
| Regulator Outputs | VDD = 3.3 V ±5 % (200 mA max); VDDOSC = 2.5 V ±5 % (50 mA max) - powers core logic and oscillator independently with internal POR/LVR. |
| Timing Resolution | Nominal macrotick length programmable from 2–100 µs; microtick resolution ≤1 µs - enables precise time-triggered scheduling for safety-critical control loops. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive applications including engine control, chassis, and ADAS domain controllers. |
| Package | 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) - JEDEC-compliant footprint with thermal pad for enhanced power dissipation in high-reliability modules. |
Pinout & Package
Package: 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch), thermally enhanced with exposed die pad (EPAD). Pin assignments conform to Figure 2-2 ("Pin Assignments for MFR4200 in 64-pin LQFP") in the Rev. 1 datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core logic supply and ground | 3.3 V regulated input for digital core; requires local 100 nF + 10 µF decoupling per datasheet Section A.1.2. |
| VDDOSC, VSSOSC | Oscillator supply and ground | 2.5 V regulated input dedicated to internal oscillator circuitry; isolated from core supply to minimize jitter coupling. |
| EXTAL, XTAL | Clock crystal terminals | Supports Pierce oscillator configuration with 1–20 MHz crystals; internal load capacitors configurable via register. |
| CLKOUT | Programmable output clock | Provides 4 MHz or 10 MHz buffered clock for external PHY or timing reference; enabled via CRG register settings. |
| TXA, RXA / TXB, RXB | Dual FlexRay channel I/O | Two independent differential physical layer interfaces (Channel A/B); each requires external PHY (e.g., TJA1080) per Figure 2-9. |
| AS, DS, RW, CS0–CS3 | Asynchronous host interface signals | Standard memory bus controls - AS (address strobe), DS (data strobe), RW (read/write), CS (chip select) - support 8-/16-bit data bus widths. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated FlexRay Protocol Engine | Hardware-accelerated frame processing eliminates host CPU overhead for time-critical slot arbitration, CRC calculation, and symbol encoding/decoding. |
| Dual Independent Host Interfaces | Runtime-selectable asynchronous memory or HCS12 interface - enables reuse across legacy and new MCU platforms without redesign. |
| On-Chip Dual-Output Regulator | Eliminates two external LDOs; reduces BOM count and PCB area while ensuring supply sequencing compliance for FlexRay timing stability. |
| Programmable Timing Parameters | Full register-set control over macrotick length, static/dynamic slot counts, cycle length, and sync frame configuration - enables cluster-specific tuning without firmware changes. |
| Cold-Start Capability | Hardware-supported startup sequence with up to 5 coldstart nodes - satisfies FlexRay cluster initialization requirements per ISO 17458-4 Annex D. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FlexRay communication controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S12XF512 (Freescale/NXP) | Integrated MCU with embedded FlexRay controller (MFR4200-derived IP), not standalone controller; lacks dual-regulator and independent host interface flexibility. | Best suited for cost-sensitive single-chip ECU designs where MCU and FlexRay are co-located; not drop-in replaceable for discrete controller roles. | Select when consolidating host processor and communication functions onto one die; avoid when requiring separate FlexRay node partitioning or dual-host interface support. |
| TJA1080A (NXP) | FlexRay transceiver (PHY only), not controller - requires external controller like MFR4200MAE40R for protocol handling. | Used downstream of MFR4200MAE40R to drive differential bus lines; cannot replace MFR4200MAE40R's MAC/logic functions. | Select as companion PHY for MFR4200MAE40R Channel A/B; never as functional alternative - serves complementary, not substitutable, role. |
Compared with MC9S12XF512 and TJA1080A, the MFR4200MAE40R uniquely provides a standalone, register-configurable FlexRay protocol engine with integrated dual-regulation and dual-host interface options - making it the only viable choice for modular, multi-MCU FlexRay network nodes requiring hardware-level timing determinism and supply independence.

FAQ
What is the primary function of the MFR4200MAE40R in an automotive FlexRay network?
The MFR4200MAE40R serves as a standalone FlexRay communication controller IC, implementing the full FlexRay v2.1 protocol stack - including time-triggered MAC layer, clock synchronization, bus guardian, and frame encoding/decoding - enabling deterministic, fault-tolerant communication between ECUs. Unlike transceivers or integrated MCUs, the MFR4200MAE40R handles protocol logic externally to the host processor, offloading critical timing tasks and ensuring strict adherence to FlexRay timing constraints.
Does the MFR4200MAE40R include an integrated voltage regulator?
Yes, the MFR4200MAE40R integrates a dual-output voltage regulator supplying VDD (3.3 V ±5 %, up to 200 mA) for core logic and VDDOSC (2.5 V ±5 %, up to 50 mA) for the oscillator circuit. This eliminates the need for two external LDOs, simplifies power design, and ensures proper supply sequencing - as confirmed in Chapter 4 and Appendix A.2 of the Rev. 1 datasheet.
Which host processor interfaces does the MFR4200MAE40R support?
The MFR4200MAE40R supports two distinct host interfaces: an 8-/16-bit asynchronous memory-mapped bus (with AS, DS, RW, CS0–CS3 signals) and an HCS12-compatible synchronous interface. Both are configurable via registers and allow direct connection to external MCUs without protocol translation - detailed in Sections 3.7.1 and 3.7.2 of the datasheet.
What package type is used for the MFR4200MAE40R?
The MFR4200MAE40R is packaged in a 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) with an exposed thermal pad (EPAD), as specified in Appendix B. This JEDEC-compliant package supports automotive thermal requirements and is validated for reflow soldering per Freescale's PCB layout recommendations in Appendix C.
Can the MFR4200MAE40R operate without an external crystal?
No - the MFR4200MAE40R requires an external crystal (1–20 MHz) connected to EXTAL/XTAL pins to drive its internal Pierce oscillator, as described in Chapter 6 and Figure 2-3. While it supports external clock input via CLKIN (Section 2.2.3), crystal operation is the default and validated configuration for automotive timing stability and jitter performance.
