Product details
Overview
XC874LM16FVA5VACKXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the standard 8051 instruction set and executing instructions at two clocks per machine cycle. It integrates 52 KB Flash, 256 B RAM, 3 KB XRAM, and a 10-bit 8-channel ADC. It operates with 5 V I/O supply and internal 2.5 V core voltage regulation, targeting automotive body electronics and industrial control.
For engineers reviewing the XC874LM16FVA5VACKXUMA1 datasheet, XC874LM16FVA5VACKXUMA1 pinout, XC874LM16FVA5VACKXUMA1 application, or XC874LM16FVA5VACKXUMA1 equivalent, key selection criteria include its integrated MultiCAN interface, CCU6 timer for motor control, LIN protocol support, and on-chip debug via JTAG - all confirmed in the official V1.5 datasheet.
Technical Context
The XC874LM16FVA5VACKXUMA1 implements a two-clock-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory architecture includes protected Flash with bank pagination, boot ROM, and separate XRAM addressing.
It features a multi-layer peripheral set: dual UARTs (one with LIN support), SSC synchronous serial interface, six-channel capture/compare unit (CCU6), Timer 21 for PWM generation, and MultiCAN controller supporting up to 16 message objects. Clock management supports external crystal, RC oscillator, or PLL-based operation with multiple power-saving modes.

Use Value: Independent I/O supply domains (VDDP0–VDDP5) isolate noisy 24 V input circuitry from clean 5 V logic; JTAG enables in-field firmware recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC874CM-13FVA5V | Same XC87xCLM family; 64 KB Flash (vs. 52 KB), identical pinout and peripheral set | Higher Flash capacity supports larger bootloader + application separation; same temperature grade (-40°C to +125°C) | Select when firmware size exceeds 52 KB or future-proofing for feature expansion is required |
| XC886CM-16FVA5V | Successor XC886 family; enhanced CPU (up to 26.7 MHz), 64 KB Flash, additional CAN channel and DMA | Higher performance and integration suit more complex real-time tasks but require PCB redesign due to different pin mapping | Choose for new designs needing higher throughput or additional peripherals; not drop-in compatible |
Compared with SAF-XC874CM-13FVA5V, this part offers lower Flash density but identical thermal and EMI robustness for cost-sensitive modules; versus XC886CM-16FVA5V, it provides proven qualification for legacy automotive platforms without migration overhead.

FAQ
What is the maximum operating frequency of the XC874LM16FVA5VACKXUMA1?
The XC874LM16FVA5VACKXUMA1 supports a maximum system clock frequency of 26.67 MHz when using the internal PLL with an external 8 MHz crystal. This is confirmed in Section 4.3.4 (On-Chip Oscillator Characteristics) and Table 4-12 of the V1.5 datasheet, where AC timing parameters are specified up to 26.67 MHz operation.
Does this MCU support in-application programming (IAP) of Flash memory?
Yes, the XC874LM16FVA5VACKXUMA1 supports in-application programming via its Flash controller and dedicated Flash registers (address range 0xF000–0xF01F). The datasheet confirms IAP capability in Section 3.3 and specifies that Flash sectors can be erased and reprogrammed while the CPU executes from other memory regions.
What is the role of the embedded voltage regulator, and can it be bypassed?
The embedded regulator generates a stable 2.5 V core supply from the 5 V I/O rail (VDDP). It cannot be bypassed - the VDDC pin must be connected to the regulator output, and no external core supply is supported. This is mandated by the power architecture described in Section 3.6 and Figure 3-12 of the datasheet.
Is the CCU6 module capable of generating complementary PWM outputs with programmable dead time?
Yes, the CCU6 module supports complementary PWM output pairs (e.g., CC60/CC61, CC62/CC63) with hardware-configurable dead-time insertion (0–1023 × TCLK) and emergency shutdown via EUDIS input. These capabilities are fully documented in Sections 3.20 and Table 3-49 of the V1.5 datasheet.
