Infineon Technologies XC886LM6FFA5VACKXUMA1

Overview

XC886LM6FFA5VACKXUMA1 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 I/O (3.3 V or 5.0 V) and 2.5 V core supply regulated on-chip. It supports CAN 2.0B via MultiCAN, 10-bit 8-channel ADC, and CCU6 for motor control - deployed in automotive body electronics and industrial motor drives.

For engineers reviewing the XC886LM6FFA5VACKXUMA1 datasheet, XC886LM6FFA5VACKXUMA1 pinout, XC886LM6FFA5VACKXUMA1 application, or XC886LM6FFA5VACKXUMA1 equivalent, key selection criteria include its integrated MultiCAN controller, on-chip voltage regulator enabling mixed-voltage I/O, flash-based reprogrammability, and CCU6 timer unit optimized for three-phase motor commutation timing.

Technical Context

The XC886LM6FFA5VACKXUMA1 implements a two-cycle-per-instruction XC800 core derived from the 8051 architecture, featuring dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory protection strategy includes flash lock bits and password-protected register access to prevent unauthorized code readout or modification.

It integrates a full MultiCAN 2.0B controller supporting up to 64 message objects, a 10-bit successive-approximation ADC with configurable sampling time and scan mode, and a Capture/Compare Unit 6 (CCU6) with three independent 16-bit timers for center-aligned PWM generation - all synchronized to a programmable PLL-derived system clock.

FAQ

Does XC886LM6FFA5VACKXUMA1 support CAN FD?

No. The device integrates MultiCAN 2.0B, compliant with ISO 11898-1:2003, supporting bit rates up to 1 Mbit/s and message objects with standard (11-bit) and extended (29-bit) identifiers. CAN FD capability requires later-generation XC87x or AURIX™ devices.

What is the maximum ADC sampling rate achievable with hardware triggering?

With ADCTRIG pin used to initiate conversions and minimum acquisition time configured, the device achieves up to 86 kSPS (11.5 µs per 10-bit conversion). This rate assumes single-channel sequential mode and internal ADC clock derived from PLL output divided by 2.

Is the on-chip voltage regulator adjustable or fixed-output?

The embedded voltage regulator delivers a fixed 2.5 V output for core logic. It accepts VDD5 input between 4.5 V and 5.5 V and maintains regulation across temperature and load; no external feedback or adjustment components are supported.

Can the CCU6 unit generate complementary PWM outputs with programmable dead time?

Yes. CCU6 provides three independent 16-bit timers with capture/compare functionality and dedicated dead-time insertion units. Each channel supports complementary output pairs (e.g., CC60OUT/CC60NOUT) with dead-time values programmable in 12.5 ns steps up to 1.6 µs.
