Product details
Overview
XMC4500F144K768ACXQMA1 from Infineon Technologies is a 32-bit ARM Cortex-M4 microcontroller with 768 KB on-chip Flash, 128 KB RAM (64 KB DSRAM + 64 KB PSRAM), 144-pin LQFP package, and industrial temperature range (-40°C to 125°C). It integrates Ethernet MAC, USB 2.0 Full-Speed OTG with PHY, dual CAN nodes, six USIC channels, four 12-bit VADCs, two 12-bit DACs, CCU4/CCU8 timers, and LEDTS - targeted for motor control, industrial PLCs, and power conversion systems.
For engineers reviewing the XMC4500F144K768ACXQMA1 datasheet, XMC4500F144K768ACXQMA1 pinout, XMC4500F144K768ACXQMA1 application, or XMC4500F144K768ACXQMA1 equivalent, key selection considerations include Flash/RAM sizing, integrated Ethernet+USB+CAN connectivity, analog subsystem resolution and channel count, real-time timer architecture (CCU4/CCU8), and extended temperature support up to 125°C.
Technical Context
The XMC4500F144K768ACXQMA1 implements a tightly coupled ARM Cortex-M4 core with FPU and MPU, supported by dual DMA controllers (GPDMA0/GPDMA1) and an Event Request Unit (ERU) for deterministic peripheral event handling. Its memory subsystem includes 1024 KB Flash (768 KB user-accessible), 16 KB ROM, and three SRAM banks (DSRAM1/2, PSRAM) with configurable bus matrix arbitration.
Peripherals are organized into two power bus areas (PBA0/PBA1): PBA0 hosts high-speed interfaces (Ethernet, USB, SDMMC, EBU), while PBA1 manages analog (VADC, DAC, POSIF), motor control (CCU4/CCU8), and timing (RTC, WDT, SCU). The USIC modules support UART, SPI (single/dual/quad), I²C, I²S, and LIN via programmable channel configuration - not fixed-function hardware blocks.
Key Specifications

|---|---|
| Core | ARM Cortex-M4 with FPU and MPU - enables floating-point math and memory isolation for safety-critical firmware partitions. |
| Flash Memory | 768 KB user Flash + 4 KB instruction cache - supports complex control algorithms and bootloader + application separation. |
| RAM | 128 KB total (64 KB DSRAM + 64 KB PSRAM) - sufficient for real-time control buffers, communication stacks, and sensor fusion data structures. |
| ADC | Four 12-bit VADCs, 8 channels each, with out-of-range comparators - allows simultaneous multi-sensor monitoring with hardware-triggered fault response. |
| CAN Interface | MultiCAN with 3 nodes, 64 message objects, up to 1 Mbit/s - meets automotive and industrial fieldbus requirements for distributed control networks. |
| Ethernet | 10/100 Mbit/s MAC with MII/RMII support - enables embedded web servers, Modbus TCP, and time-sensitive networking in factory automation. |

| Package | LQFP-144, 0.5 mm pitch - compatible with standard PCB assembly processes and offers full signal accessibility for debug and validation. |
Pinout & Package
Package: LQFP-144 (144-pin Low-Profile Quad Flat Package), 20 × 20 mm body, 0.5 mm lead pitch, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP0/VDDP1 | Digital Power Supply (1.3 V) | Core logic supply - requires low-noise regulation; decoupling mandatory per datasheet layout guidelines. |
| VDDA | Analog Power Supply (3.3 V) | Separate analog domain supply - isolates noise-sensitive ADC/DAC operation from digital switching transients. |
| VSSA | Analog Ground | Dedicated analog reference plane - must be connected to system ground at single point to prevent ground loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XMC4400F144K512ACXQMA1 | Same LQFP-144 package, but 512 KB Flash, no Ethernet MAC, no USB PHY. | Targeted for cost-sensitive motor control where Ethernet/USB are unnecessary. | Select when Flash budget < 600 KB suffices and fieldbus-only (CAN/RS-485) connectivity is adequate. |
| STM32H743VI | ARM Cortex-M7, 2 MB Flash, 1 MB RAM, no integrated Ethernet PHY, requires external PHY for MII. | Better raw compute throughput, but higher BOM cost and larger PCB footprint due to external PHY and DDR routing. | Prefer for AI-on-edge inference workloads; avoid if Ethernet PHY integration and thermal robustness at 125°C are mandatory. |
Compared with XMC4400F144K512ACXQMA1, this part adds Ethernet+USB PHY and 256 KB more Flash - essential for gateway firmware with TLS stacks and web UIs. Versus STM32H743VI, it trades peak CPU performance for lower system-level integration, smaller form factor, and guaranteed 125°C operation without derating.

Manufacturer
Infineon Technologies is a German semiconductor manufacturer specializing in power management, automotive ICs, and industrial microcontrollers, with R&D centers across Europe, Asia, and the Americas.
The XMC4000 family was designed specifically for industrial real-time control - emphasizing deterministic peripherals (CCU8, POSIF), analog integration (VADC, DAC), and fieldbus connectivity (CAN, Ethernet) rather than general-purpose computing.
FAQ
Does XMC4500F144K768ACXQMA1 support hardware encryption acceleration?
No. This device lacks dedicated cryptographic accelerators (AES, SHA, TRNG). Security relies on software libraries or external secure elements. The integrated Flash supports read-out protection and write protection via SCU registers, but no hardware crypto engine is present per the XMC4500 datasheet v1.7 Section 3.2.9 and Reference Manual Chapter 12.3.
What is the maximum achievable PWM frequency using CCU8 timers?
CCU8 supports PWM output up to 72 MHz - derived from the 144 MHz system clock divided by minimum prescaler value (1) and minimum period register setting (2). Achievable resolution depends on clock source and counter configuration; 100 ns minimum pulse width is attainable with proper clock tree setup, as specified in XMC4500 Reference Manual Section 15.4.3.
Is the integrated USB PHY compliant with USB Battery Charging (BC) 1.2 specification?
No. The USB 2.0 Full-Speed OTG PHY supports device/host modes and standard USB enumeration, but does not implement BC 1.2 charging port detection (SDP/CDP/DCP) logic. External charging controller ICs are required for proprietary fast-charge protocols or USB-BC 1.2 compliance, per Infineon Application Note AP32271.
Can the SDMMC interface operate in 4-bit wide data mode with UHS-I support?
Yes, SDMMC supports 4-bit SD mode at up to 25 MHz clock (100 MB/s theoretical), but not UHS-I (which requires 1.8 V signaling and SDR50/DDR50 modes). The interface operates only at 3.3 V signaling and lacks UHS-I voltage switching or timing modes, as confirmed in XMC4500 Datasheet Section 3.3.9.5 and Reference Manual Chapter 22.
