Product details
Overview
XC8886FFI5VACFXUMA1 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 in two clock cycles. It integrates 32 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM; features a 10-bit 8-channel ADC, MultiCAN interface, CCU6 capture/compare unit, and embedded 2.5 V voltage regulator for core logic. It targets automotive body electronics and industrial control systems requiring LIN and CAN communication.
For engineers reviewing the XC8886FFI5VACFXUMA1 datasheet, XC8886FFI5VACFXUMA1 pinout, XC8886FFI5VACFXUMA1 application, or XC8886FFI5VACFXUMA1 equivalent, key selection criteria include Flash size (32 KB), dual supply domains (3.3 V/5.0 V I/O + 2.5 V core), integrated MultiCAN v2.0 controller, LIN 2.1 support, and on-chip debug via JTAG/OCDS.
Technical Context
The XC8886FFI5VACFXUMA1 implements the XC800 architecture with two data pointers and no wait states for internal memory access. Its clock generation unit supports external crystal (1–20 MHz), RC oscillator, and PLL-based system clock up to 27 MHz, enabling deterministic timing for real-time control loops.
It integrates a dedicated MultiCAN module compliant with CAN 2.0B protocol, supporting up to 64 message objects and hardware message filtering. The CCU6 unit provides six PWM channels with dead-time insertion and emergency shutdown-critical for motor control and power conversion applications.

Pinout & Package
XC8886FFI5VACFXUMA1 is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across six bidirectional I/O ports (P0–P5), each configurable as digital I/O or peripheral multiplexed signals including CAN TX/RX, LIN, UART, SSC, CCU6 outputs, and ADC inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 bidirectional I/O / AD0–AD7 | 8-bit multiplexed address/data bus or analog input channel group for ADC; requires external pull-ups when used as general-purpose I/O. |
| P1.0–P1.7 | Port 1 bidirectional I/O / CAN0_TX, CAN0_RX, LIN | Dedicated pins for CAN0 transceiver interface and LIN physical layer; supports slew-rate controlled output for EMC compliance. |

Key Features
| Feature | Design Value |
|---|---|
| Embedded Voltage Regulator | On-die 2.5 V regulator supplies core logic independently of I/O voltage (3.3 V or 5.0 V), simplifying power design and improving noise immunity. |
| Memory Protection Strategy | Flash and ROM sectors protected via password-locked write/erase access, preventing accidental overwrites during field updates or debugging. |
| CORDIC Coprocessor | Hardware-accelerated trigonometric and hyperbolic function engine (sin/cos/tan/atan/sqrt/log), reducing CPU load in motor control and sensor fusion algorithms. |
| MultiCAN Message Objects | 64 independent message objects with priority-based transmission scheduling and hardware timestamping for deterministic network behavior. |
| Power Saving Modes | Four low-power modes (IDLE, STOP, STANDBY, POWER-DOWN) with wake-up via CAN/LIN/external interrupt, enabling sub-10 µA standby current. |

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 |
|---|---|---|---|
| XC8866FFI5VACFXUMA1 | 24 KB Flash (vs. 32 KB), identical pinout and peripheral set; lacks 8 KB additional Flash for bootloader redundancy. | Suitable for cost-sensitive LIN-only nodes without CAN or complex firmware update requirements. | Select when Flash budget is constrained and MultiCAN is not required. |
| SAK-TC1766-128F133HR BA | TriCore 32-bit architecture, 133 MHz, 128 KB Flash; no XC800 compatibility; requires toolchain migration. | Targeted at next-generation BCU designs needing higher compute throughput and ASIL-B compliance. | Choose for new designs requiring ISO 26262 functional safety support and >10× performance uplift. |
Compared with XC8886FFI5VACFXUMA1, the XC8866FFI5VACFXUMA1 offers identical footprint and peripheral compatibility but reduced Flash capacity, while the TC1766 delivers significantly higher performance and safety certification at the cost of architecture migration and increased BOM complexity.

FAQ
Does XC8886FFI5VACFXUMA1 support CAN FD?
No. XC8886FFI5VACFXUMA1 implements MultiCAN v2.0 compliant with ISO 11898-1:2003, supporting only classical CAN (up to 1 Mbps). It does not include CAN FD framing, bit-rate switching, or extended data length capabilities. For CAN FD, consider Infineon's AURIX™ TC3xx series.
What is the maximum operating frequency of the XC800 core?
The XC800 core operates at up to 27 MHz system clock frequency, achieved via internal PLL multiplication of an external crystal (e.g., 12 MHz crystal × 2.25 = 27 MHz). At this frequency, it delivers 13.5 MIPS due to its two-clock-cycle per instruction architecture.
Can the internal voltage regulator power external circuitry?
No. The embedded 2.5 V regulator is strictly for internal core logic supply. It is not rated for external load driving and lacks current capability beyond MCU core consumption (~20 mA typical). External regulators must be used for auxiliary 2.5 V rails.
Is the Boot ROM field-programmable?
No. The 12 KB Boot ROM is factory-programmed and read-only. It contains the boot loader and basic initialization routines. Firmware updates are performed via the user-accessible 32 KB Flash memory, which supports in-system programming through UART or CAN interfaces.
