Product details
Overview
SAF-XC886CM-8FFI 3V3 AC 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 24 KB Flash, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-supply operation (3.3 V I/O, 2.5 V core via embedded regulator), and supports LIN, UART, MultiCAN, and 10-bit 8-channel ADC for automotive body electronics control.
For engineers reviewing the SAF-XC886CM-8FFI 3V3 AC datasheet, SAF-XC886CM-8FFI 3V3 AC pinout, SAF-XC886CM-8FFI 3V3 AC application, or SAF-XC886CM-8FFI 3V3 AC equivalent, key selection criteria include Flash size and memory protection, LIN/UART timing compliance, ADC resolution and channel count, MultiCAN message object support, and 3.3 V I/O voltage tolerance in mixed-voltage systems.
Technical Context
The XC886CM 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 subsystem includes segmented Flash with sector-based erase, boot ROM with configurable reset vector, and XRAM accessible via MOVX with paging/mapping extensions.
Peripheral integration centers on automotive communication and timing: MultiCAN controller with 16 message objects, LIN 2.1-compliant UART1 with automatic baud rate detection, CCU6 for PWM generation, Timer 21 for high-resolution capture, and 10-bit ADC with programmable sampling time and sequence control - all synchronized to a PLL-stabilized clock derived from internal oscillator or external crystal.
Key Specifications

|---|---|
| CPU Core | XC800 (8051-compatible), 2-clock/machine cycle → enables zero-wait-state execution from Flash at up to 26.7 MHz core frequency |
| Flash Memory | 24 KB on-chip Flash with sector erase, write/erase endurance ≥10k cycles → supports field firmware updates and secure boot code storage |
| ADC | 10-bit SAR ADC, 8 input channels, programmable sampling time → delivers ±1 LSB INL/DNL for precise sensor signal acquisition in body control modules |
| MultiCAN Interface | Two CAN nodes, 16 message objects, FIFO support, bit rate up to 1 Mbps → enables dual-bus communication for gateway or junction box applications |
| LIN Support | UART1 with hardware LIN header detection and auto-baud rate sync → eliminates external LIN transceiver for slave-node implementation in door modules or seat controls |
| Supply Architecture | I/O supply: 3.3 V ±10 %; core supply: 2.5 V generated internally → simplifies power design by removing need for external core LDO in 3.3 V systems |
| Operating Temperature | –40 °C to +125 °C (Grade A) → qualified for under-hood and interior automotive environments per AEC-Q100 |
Pinout & Package

| VDDIO | I/O power supply | 3.3 V supply pin for all GPIOs and peripheral I/O buffers; must be decoupled locally with 100 nF ceramic capacitor |
| VDDCORE | Core logic supply | Internally regulated 2.5 V output from embedded voltage regulator; externally bypassed to reduce switching noise on core domain |
| XTAL1/XTAL2 | Crystal oscillator input/output | Supports 1–20 MHz quartz crystal or external clock source; internal oscillator usable without crystal for cost-sensitive LIN-only applications |
Key Features
| Feature | Design Value |
|---|---|
| Embedded Voltage Regulator | Generates stable 2.5 V core supply from 3.3 V I/O rail → eliminates external core LDO and reduces BOM count in 3.3 V automotive systems |

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-XC886CLM-8FFI 3V3 AC | Same XC800 core and peripherals, but uses 12 KB ROM + 4 KB Flash instead of 24 KB Flash; no Boot ROM reprogrammability | Suitable for fixed-function, high-volume modules where firmware never changes post-manufacture (e.g., basic mirror control) | Select when firmware immutability and lower cost outweigh field update capability |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, integrated CAN FD, no LIN hardware acceleration | Targets higher-tier BCMs requiring CAN FD bandwidth and ASIL-B functional safety compliance | Select only when migrating to 32-bit platform with safety certification requirements |
Compared with SAF-XC886CM-8FFI 3V3 AC, the ROM-based XC886CLM variant trades field-upgradable Flash for lower unit cost and guaranteed boot integrity, while the SPC560B50L5 offers scalable performance and CAN FD at the expense of LIN hardware support and higher power/complexity.

FAQ
Does SAF-XC886CM-8FFI 3V3 AC support JTAG debugging in production environments?
Yes, it features full On-Chip Debug Support (OCDS) compliant with IEEE 1149.1 JTAG, including boundary scan, real-time trace, and non-intrusive breakpoints. The JTAG interface remains active in all operating modes except deep power-down, and supports flash programming and secure debug authentication via password-protected access registers.
What is the maximum ADC sampling rate achievable with this MCU?
The 10-bit ADC achieves up to 100 kS/s conversion rate when configured for single-channel, free-running mode with minimum sampling time (1.5 µs). With 8-channel sequential conversion and 12.5 µs sampling time per channel, sustained throughput is ~12.5 kS/s across all channels, limited by internal ADC clock division and conversion timing parameters specified in Section 4.2.3 of the datasheet.
Can the embedded voltage regulator supply external circuitry?
No - the internal 2.5 V regulator is dedicated solely to powering the core logic and is not rated for external load. Its output is internally routed and lacks external pins or current-sinking capability. External circuits requiring 2.5 V must use a separate regulator; VDDCORE is for decoupling only and must be connected to a 100 nF capacitor to ground.
Is LIN communication supported without an external transceiver?
Yes - UART1 provides full LIN 2.1 physical layer support including automatic header detection, sync field generation, and checksum calculation. When paired with a simple discrete LIN driver (e.g., TLE7259-2), it operates as a complete LIN slave node. For master functionality, external level-shifting and slew-rate control are required per ISO 17987-2.
