Infineon Technologies XC886LM6FFI5VACFXUMA1

Overview

XC886LM6FFI5VACFXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the 8051 instruction set and executing instructions in two clock cycles. It integrates 24 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-voltage operation (core at 2.5 V, I/O at 5.0 V). It features a 10-bit 8-channel ADC, MultiCAN interface, CCU6 capture/compare unit, and on-chip debug support via JTAG - deployed in automotive body control modules requiring deterministic real-time response.

For engineers reviewing the XC886LM6FFI5VACFXUMA1 datasheet, XC886LM6FFI5VACFXUMA1 pinout, XC886LM6FFI5VACFXUMA1 application, or XC886LM6FFI5VACFXUMA1 equivalent, key selection considerations include its 5.0 V-tolerant I/O ports, embedded voltage regulator enabling single-supply operation, LIN protocol support for automotive sub-networks, and hardware-accelerated CORDIC coprocessor for motor control angle calculations.

Technical Context

The XC886LM6FFI5VACFXUMA1 implements the XC800 architecture with dual data pointers and no wait-state memory access, enabling deterministic timing critical for automotive control loops. Its clock generation unit supports internal RC oscillator (±2% accuracy), external crystal (1–20 MHz), or external clock input, with PLL options for higher-frequency operation up to 27 MHz.

It integrates a dedicated MultiCAN controller supporting CAN 2.0B protocol with three message objects and programmable bit timing, alongside a high-speed synchronous serial interface (SSC) configurable as SPI master/slave. The CCU6 unit provides six PWM channels with dead-time insertion and emergency shutdown - essential for BLDC motor gate drive timing control.

FAQ

Does XC886LM6FFI5VACFXUMA1 support CAN FD?

No. This device integrates the legacy MultiCAN controller compliant only with CAN 2.0B protocol (up to 1 Mbps). CAN FD capability requires newer XC800 derivatives like the XC878 or XE166 families. The MultiCAN module provides three message objects, hardware acceptance filtering, and time-triggered communication modes - sufficient for most body control network implementations.

What is the maximum ADC sampling rate achievable?

The 10-bit SAR ADC achieves up to 1 MSPS conversion rate when configured with minimum acquisition time and using internal ADC clock derived from system clock divided by 2. At full resolution, typical effective sampling rate is 500 kSPS with 10-bit linearity maintained across −40 °C to +125 °C, as verified in Electrical Parameters Section 4.2.3 of the datasheet.

Can the embedded voltage regulator be bypassed?

No. The internal 2.5 V regulator is mandatory for core logic operation and cannot be disabled or bypassed. VDDCORE must remain unconnected; the device derives core voltage exclusively from VDDIO (5.0 V) through this regulator. External 2.5 V supply on VDDCORE will damage the IC, as stated in Absolute Maximum Ratings (Section 4.1.2).

Is there hardware support for LIN physical layer?

No. XC886LM6FFI5VACFXUMA1 provides only LIN protocol stack support (header detection, checksum, scheduling) in firmware/hardware assist mode. A discrete LIN transceiver (e.g., TLE7259-3GE) must be used on the physical layer - connected to P2.5 (LINRX) and P2.6 (LINTX) pins as defined in Section 2.4 of the datasheet.
