Product details
Overview
XC888LM6FFA5VACKXUMA1 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 32 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-voltage I/O (3.3 V or 5.0 V) and a 2.5 V core supplied by an embedded voltage regulator. It supports CAN 2.0B via MultiCAN, LIN, UART, SSC, 10-bit 8-channel ADC, CCU6, and on-chip debug via JTAG.
For engineers reviewing the XC888LM6FFA5VACKXUMA1 datasheet, XC888LM6FFA5VACKXUMA1 pinout, XC888LM6FFA5VACKXUMA1 application, or XC888LM6FFA5VACKXUMA1 equivalent, key selection criteria include Flash size (32 KB), MultiCAN interface support, 10-bit ADC resolution with 8 channels, dual-voltage I/O capability, and integrated boot ROM for secure startup in automotive body electronics and industrial control systems.
Technical Context
The XC888LM6FFA5VACKXUMA1 implements the XC800 architecture with a two-clock-per-machine-cycle execution engine, enabling zero-wait-state memory access. Its memory subsystem includes 32 KB of user-programmable Flash, 12 KB of factory-programmed Boot ROM, and hierarchical RAM resources (256 B internal + 1.5 KB XRAM), all protected by configurable flash lock bits and bit-level protection schemes.
It features a dedicated MultiCAN controller compliant with CAN 2.0B protocol, supporting up to 64 message objects and flexible message filtering. The analog subsystem integrates a 10-bit successive-approximation ADC with 8 input channels, programmable sampling time, and conversion trigger sources including timer overflows and external events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 (8051-compatible), 2-clock/machine cycle → enables deterministic timing and eliminates wait states for internal memory access. |
| Flash Memory | 32 KB on-chip Flash → stores application firmware with in-system programmability and memory protection. |
| Boot ROM | 12 KB factory-programmed ROM → contains bootloader and system initialization routines for secure startup and firmware update support. |
| ADC Resolution & Channels | 10-bit SAR ADC with 8 input channels → provides sufficient dynamic range and channel count for sensor monitoring in motor control and HVAC systems. |
| MultiCAN Interface | CAN 2.0B-compliant controller with 64 message objects → enables robust, prioritized communication in automotive networked ECUs. |
| I/O Voltage Support | 3.3 V or 5.0 V I/O supply with 2.5 V core → allows direct interfacing with legacy 5 V peripherals while maintaining low-power core operation. |

Pinout & Package
XC888LM6FFA5VACKXUMA1 is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad, optimized for thermal dissipation in automotive and industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP0–VDDP3 | I/O Power Supply | Four independent 3.3/5.0 V I/O supply pins → enable mixed-voltage port grouping and noise isolation between peripheral domains. |
| VSSP0–VSSP3 | I/O Ground | Dedicated I/O return paths per supply domain → minimize ground bounce and crosstalk in high-speed digital I/O operation. |
| VDD | Core Power Supply | 2.5 V core supply (internally regulated) → ensures stable CPU and peripheral operation independent of I/O rail fluctuations. |
| XTAL1/XTAL2 | Crystal Oscillator Input/Output | Supports external quartz crystal (1–20 MHz) or external clock source → provides precise, low-jitter system clock generation. |
| CANRX/CANTX | CAN Transceiver Interface | Differential CAN bus signal pins → connect directly to external CAN transceiver (e.g., TJA1040) for ISO 11898-2 compliance. |
| ADCTRIG | ADC Conversion Trigger | External event input for synchronous ADC sampling → enables precise timing alignment with motor commutation or PWM edges. |
Key Features
| Feature | Design Value |
|---|---|
| XC800 Core with 2-clock cycle | Enables full 8051 compatibility while doubling instruction throughput vs. legacy 12-clock cores - critical for real-time control loop execution. |
| MultiCAN Controller (64 objects) | Supports complex automotive messaging topologies with hardware message filtering and priority arbitration - reduces CPU overhead in ECU networks. |
| 10-bit 8-channel ADC with flexible triggers | Allows simultaneous sampling of multiple sensors (e.g., temperature, current, position) with software- or timer-synchronized acquisition - essential for closed-loop motor control. |
| Boot ROM + Flash memory protection | Prevents unauthorized firmware modification and ensures bootloader integrity - required for ASIL-B functional safety compliance in body control modules. |
| Dual-voltage I/O (3.3 V / 5.0 V) | Eliminates level-shifting components when interfacing with legacy 5 V sensors or actuators - simplifies PCB design and improves system reliability. |

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 |
|---|---|---|---|
| XC878CM-16F64L | Same XC800 core, but 16 MHz max frequency (vs. 27 MHz), 64-pin LQFP, 64 KB Flash, no Boot ROM. | Lacks factory-programmed Boot ROM → requires external bootloader implementation for firmware updates. | Select when higher Flash capacity is needed and bootloader flexibility outweighs certified boot security. |
| S9S08DZ32F2MLH | Freescale S08 core, 32 KB Flash, 2 KB RAM, LIN-only (no CAN), 8-bit ADC (8 ch), 5 V only I/O. | No CAN interface and fixed 5 V I/O → unsuitable for mixed-voltage or CAN-based architectures. | Select only for cost-sensitive LIN-only applications where CAN integration is unnecessary. |
Compared with XC888LM6FFA5VACKXUMA1, the XC878CM-16F64L offers more Flash but sacrifices boot security and maximum clock speed, while the S9S08DZ32F2MLH lacks CAN and dual-voltage I/O - making the XC888LM6FFA5VACKXUMA1 uniquely suited for safety-aware, CAN-connected automotive body electronics.

FAQ
What is the maximum operating frequency of the XC888LM6FFA5VACKXUMA1?
The XC888LM6FFA5VACKXUMA1 supports a maximum CPU clock frequency of 27 MHz, achieved using the on-chip PLL with an external crystal (e.g., 11.0592 MHz or 20 MHz). This enables a 13.5 MHz instruction execution rate under the two-clock-per-cycle architecture, delivering deterministic timing for real-time control loops in motor and lighting applications.
Does this microcontroller support CAN FD or only classical CAN?
The XC888LM6FFA5VACKXUMA1 implements MultiCAN compliant with ISO 11898-1:2003 (Classical CAN 2.0B only) and does not support CAN FD. It provides 64 message objects, hardware acceptance filtering, and transmit priority arbitration - sufficient for most automotive body network requirements but not for high-bandwidth infotainment or ADAS backbones requiring CAN FD data rates.
Is the Boot ROM field-programmable or factory-programmed only?
The 12 KB Boot ROM is factory-programmed by Infineon and cannot be modified in the field. It contains a certified bootloader supporting serial (UART) firmware updates, CRC validation, and secure entry into user Flash - ensuring verified startup and protection against corrupted or malicious firmware images in safety-critical deployments.
What debug interfaces are supported, and is SWD available?
The XC888LM6FFA5VACKXUMA1 supports only JTAG-based On-Chip Debug Support (OCDS) per the Infineon specification; it does not implement Serial Wire Debug (SWD). Debugging requires a JTAG adapter (e.g., Infineon DAS or compatible third-party tools) and supports breakpoints, watchpoints, register inspection, and flash programming through standard IDEs like Keil µVision or Tasking VX Toolset.
