Product details
Overview
XC228796F80LACKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 family, featuring an 80 MHz CPU clock, 768 KB on-chip Flash memory, 64 KB PSRAM, dual A/D converters (24 channels total, 10-bit, <1 µs conversion), and integrated MultiCAN (5 nodes, 128 message objects). It serves as a real-time control core in automotive powertrain and chassis systems requiring deterministic timing and high I/O density.
For engineers reviewing the XC228796F80LACKXUMA1 datasheet, XC228796F80LACKXUMA1 pinout, XC228796F80LACKXUMA1 application, or XC228796F80LACKXUMA1 equivalent, key selection criteria include CAN node count, ADC channel resolution and preprocessing capability, CCU6x PWM flexibility, external bus interface width, and industrial temperature grade (-40 °C to 125 °C) compliance.
Technical Context
The XC228796F80LACKXUMA1 implements a five-stage pipelined C166-compatible CPU with 12.5 ns instruction cycle at 80 MHz, supporting zero-cycle jumps and fast context switching via dual local register banks. Its memory subsystem includes 768 KB Flash (with ECC), 64 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 1 KB SBRAM - all mapped within a unified 16 MB linear address space.
Peripheral integration centers on deterministic real-time control: two synchronizable 10-bit ADCs with hardware data reduction, four CCU6x units for independent PWM generation, CAPCOM2 for capture/compare, GPT12E timers, and a fully compliant MultiCAN Rev. 2.0B controller with gateway functionality across five CAN nodes - all accessible via JTAG-based OCDS debug support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 80 MHz maximum - enables 12.5 ns instruction cycle for hard real-time loop execution in engine control units. |
| Flash Memory | 768 KB on-chip Flash with ECC - supports robust firmware storage and field updates in safety-critical automotive applications. |
| ADC Resolution & Speed | 10-bit, sub-1 µs conversion time per sample - meets fast-sampling requirements for crankshaft position and knock detection. |
| CAN Nodes | 5 independent CAN 2.0B nodes - enables full vehicle network integration (powertrain, chassis, body) without external bridge ICs. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood deployment in modern ICE and hybrid powertrain ECUs. |

Pinout & Package
XC228796F80LACKXUMA1 is housed in a 144-pin Green LQFP package (19.7 mil / 0.5 mm pitch) with exposed thermal pad, compliant with RoHS and halogen-free standards. Pin functions are defined across multiple voltage domains (M, P, V, R) for mixed-signal isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XTAL1 / XTAL2 | Crystal oscillator input/output | Accepts 1–20 MHz fundamental-mode crystals; internal PLL generates 80 MHz system clock with jitter < ±50 ps RMS. |
| VDDP / VSSP | Analog power supply / ground | Separate 3.3 V analog domain powers ADC and PLL - critical for <1 LSB INL error and stable clock synthesis. |
| ADCTRIGx | Hardware ADC trigger input | Synchronizes sampling to engine crankshaft position signals - eliminates software latency in closed-loop combustion control. |
| CANRX0–CANRX4 | CAN receive inputs (5 nodes) | Dedicated Schmitt-triggered inputs with fail-safe biasing - tolerate ±25 V common-mode noise in automotive harness environments. |
| CC60–CC63 | CCU6x PWM output terminals | Drive gate drivers for 3-phase inverter stages with programmable dead-time insertion and fault blanking (min. 50 ns). |
Key Features
| Feature | Design Value |
|---|---|
| MultiCAN Rev. 2.0B with Gateway | Routes messages between 5 CAN networks using hardware FIFOs and filter tables - reduces CPU load by >70% vs. software bridging. |
| Dual Synchronizable ADCs | 24-channel, 10-bit, simultaneous sampling with hardware range-check and averaging - enables cylinder-specific knock detection without DMA overhead. |
| CCU6x PWM Units | Four independent 16-bit units with center-aligned mode, emergency shutdown, and shadow register update - supports motor control and digital power conversion. |
| Peripheral Event Controller (PEC) | 8-channel DMA engine with 24-bit addressing - transfers ADC results or CAN buffers autonomously while CPU executes control algorithms. |
| On-Chip Debug Support (OCDS) | JTAG interface with real-time trace, breakpoint watchpoints, and memory access during run mode - enables non-intrusive validation of timing-critical ISRs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-XC2287-96F80L | Same die, identical electrical specs and pinout; differs only in tape-and-reel packaging (no tray option) and marking format. | No functional difference; suitable for automated SMT lines requiring reel delivery. | Select when production volume justifies reel-based placement and traceability requirements align with Infineon's standard reel labeling. |
| SAK-XC2267-96F80L | Lower peripheral count: 3 CAN nodes (vs. 5), no CCU6x units, only one ADC (16 channels), 512 KB Flash. | Limited to entry-level chassis modules (e.g., HVAC control) where multi-network routing or high-resolution motor control is unnecessary. | Choose for cost-sensitive designs where full XC2287 feature set is unused - saves ~18% BOM cost but sacrifices scalability. |
Compared with SAK-XC2287-96F80L, this part offers identical functionality with different logistics coding; versus SAK-XC2267-96F80L, it delivers 67% more CAN bandwidth, full PWM motor control capability, and 50% larger Flash - essential for scalable ECU platforms targeting ASIL-C compliance.

Does XC228796F80LACKXUMA1 support hardware-based functional safety mechanisms per ISO 26262?
Yes - it includes lockstep-capable peripherals (e.g., dual watchdogs, parity/ECC on Flash and SRAM, memory protection unit), diagnostic libraries, and hardware error signaling paths. While not ASIL-D certified out-of-box, it provides the foundational hardware features required for ASIL-B/C system-level certification when implemented per Infineon's SafeTcore guidelines.
How many CAN message objects does the MultiCAN module support, and are they configurable per node?
The MultiCAN module supports up to 128 message objects total, distributed across five CAN nodes. Each node has independent acceptance filtering, transmit/receive FIFOs, and configurable object allocation - allowing flexible assignment (e.g., 32 objects to CAN0 for powertrain, 16 to CAN1 for chassis) without firmware overhead.
Is external memory expansion supported, and what bus configurations are available?
Yes - the External Bus Controller supports up to 12 MB address space with programmable 8-bit or 16-bit data bus width, multiplexed or demultiplexed modes, five chip-select outputs, and hold/acknowledge arbitration.
