Product details
Overview
SAF-XC888LM-6FFI3V3AC 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 per machine cycle. It integrates 32 KB Flash memory, 256 B RAM, 1.5 KB XRAM, 12 KB Boot ROM, a 10-bit 8-channel ADC, MultiCAN interface, and operates with core logic at 2.5 V (internally regulated) and I/O ports at 3.3 V. It is used in automotive body electronics and industrial motor control systems requiring LIN and CAN communication.
For engineers reviewing the SAF-XC888LM-6FFI3V3AC datasheet, SAF-XC888LM-6FFI3V3AC pinout, SAF-XC888LM-6FFI3V3AC application, or SAF-XC888LM-6FFI3V3AC equivalent, key selection considerations include its dual-voltage I/O (3.3 V), embedded 2.5 V regulator, MultiCAN v2.0B support, LIN 2.1 compliance, and 16-bit CCU6 timer for precise PWM generation in motor drive applications.
Technical Context
The XC888LM implements the XC800 8051-compatible core with two-clock-per-cycle execution, enabling zero-wait-state memory access. Its memory subsystem includes 32 KB on-chip Flash (with sector protection), 12 KB Boot ROM, and separate 256 B RAM + 1.5 KB XRAM spaces mapped via paging and address extension.
Peripherals are tightly integrated for real-time control: MultiCAN supports up to 64 message objects with hardware acceptance filtering; CCU6 provides six capture/compare channels with dead-time insertion; and the 10-bit ADC features configurable conversion sequences with hardware trigger synchronization to timers or external events.

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-XC886LM-6FFI3V3AC | 24 KB Flash (vs. 32 KB), identical peripheral set, same package and voltage configuration. | Suitable for cost-sensitive designs with smaller firmware footprint and no need for extended data logging or bootloader space. | Select when firmware size remains under 22 KB and no future feature expansion is planned. |
| TLE9842-2QX | ARM Cortex-M0 core, integrated high-side/low-side drivers, no external transceiver needed for basic CAN/LIN. | Targets higher integration density and lower BOM count in new designs where ARM toolchain adoption is acceptable. | Prefer for next-generation designs requiring higher compute throughput and integrated power stages. |
Compared with SAF-XC888LM-6FFI3V3AC, the XC886 variant trades Flash capacity for cost reduction while preserving timing-critical peripherals; the TLE9842 shifts to ARM architecture and adds power drivers, increasing integration but requiring toolchain migration and losing 8051 ecosystem compatibility.

FAQ
Does SAF-XC888LM-6FFI3V3AC support CAN FD?
No. This device implements MultiCAN v2.0B only, supporting classical CAN with up to 1 Mbit/s bit rate and 11-bit or 29-bit identifiers. CAN FD requires different message framing, CRC calculation, and higher-speed transceivers not supported by the on-chip controller.
What is the maximum ADC sampling rate achievable with hardware triggering?
With the ADC clock derived from the system clock divided by 4 (typical configuration), and minimum conversion time of 13 ADC clocks per sample, the maximum sustained sampling rate is 769 kSPS. This assumes continuous trigger pulses aligned to conversion completion and no software overhead.
Is the embedded voltage regulator enabled by default after reset?
Yes. The internal 2.5 V regulator is active immediately after power-on reset and cannot be disabled. It supplies the CPU core, flash controller, and most peripherals; only I/O ports and certain analog blocks operate from VDDIO.
Can the CCU6 module generate complementary PWM outputs with programmable dead time?
Yes. CCU6 supports six independent compare channels, each configurable for complementary output pairs with user-defined dead-time values (1–127 system clock cycles), synchronized start/stop, and emergency shutdown via external fault input (CCPOS0).
