MPXR4040VVU264
MPXR4040VVU264 - 264MHz 32-bit MCU with 4MB Flash | NXP
The NXP Semiconductors MPXR4040VVU264 is a 32-bit Power Architecture e200z7 microcontroller rated at 264 MHz, with 4 MB of flash program memory and 416-ball PBGA packaging. The verified product listing identifies 198 I/O, CANbus, LINbus, SCI, SPI, UART/USART, DMA, PWM, and watchdog connectivity. Its industrial temperature-grade marking and 27 x 27 mm package position it for real-time embedded control systems requiring high processing performance and extensive peripheral integration.
A microcontroller is a programmable system-on-chip that combines a processor core, memory, communication peripherals, timers, and I/O in one device. The MPXR4040VVU264 belongs to the PX Series and uses a 32-bit e200z7 core built around Power Architecture technology. This places it in the embedded-controller hierarchy: MCU -> real-time processor -> embedded semiconductor. Its combination of local flash, serial interfaces, and real-time peripherals supports industrial networking, machine control, automotive-style communications, and test equipment without requiring a separate external processor.
The verified data confirms a 264 MHz operating speed, 4 MB (4M x 8) flash, 32-bit processing, 198 I/O, and a 416-terminal square BGA package. The available connectivity includes CANbus, EBI/EMI, LINbus, SCI, SPI, UART/USART, DMA, POR, PWM, and WDT. These interfaces allow the device to coordinate networked nodes, external memories, actuator controls, and real-time data paths. The 198 available I/O provide substantial board-level integration for sensors, communication transceivers, power-control signals, and industrial logic.
The e200z7 architecture and 264 MHz class position the part in performance-oriented real-time embedded designs rather than low-cost basic control. Flash memory supports local firmware storage, while DMA can reduce processor involvement in data transfers. PWM and watchdog resources support periodic actuator drive and system monitoring, and the communication peripherals cover common industrial and embedded control buses. The supplied data does not specify RAM capacity beyond a conflicting distributor snippet, operating voltage, memory-map details, or electrical timing limits.
Typical applications include industrial automation controllers, CAN and LIN network nodes, motor and power-control systems, communications equipment, and embedded test or measurement platforms. Designers should prioritize the 416-ball PBGA layout and verify the exact pin-level requirements, power rails, clock configuration, and board-level escape routing before layout begins. Because the package uses 416 balls rather than a leaded package, a multilayer PCB and appropriate assembly process are normally required.
The MPXR4040VVU264 is listed as obsolete by one datasheet source, so procurement should confirm lifecycle and counterfeit risk before committing to new production. LCSC shows a price from $1.0048 in the verified search result, while Heisener reports inventory but requests a quotation. These figures are commercial snapshots, not guaranteed XAIPART inventory or a universal replacement price.
This page consolidates verified distributor specifications, interface details, lifecycle signals, sourcing context, and engineering caveats. It is intended to help engineers distinguish the obsolete controller from possible alternatives, assess compatibility, and plan a controlled redesign rather than assuming that any cross-reference is automatically pin-to-pin equivalent.
