Infineon Technologies XC886C8FFA5VACKXUMA1

Overview

XC886C8FFA5VACKXUMA1 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, 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 generated internally. It supports CAN 2.0B via MultiCAN, 10-bit 8-channel ADC, and LIN protocol - deployed in automotive body control modules requiring deterministic real-time response.

For engineers reviewing the XC886C8FFA5VACKXUMA1 datasheet, XC886C8FFA5VACKXUMA1 pinout, XC886C8FFA5VACKXUMA1 application, or XC886C8FFA5VACKXUMA1 equivalent, key selection criteria include Flash size vs. ROM variant trade-offs, embedded voltage regulator operation at 2.5 V core, MultiCAN message object count (32), SSC master timing compliance, and LIN header detection capability per DS V1.2 §89.

Technical Context

The XC886C8FFA5VACKXUMA1 implements a two-clock-per-machine-cycle 8051-compatible CPU with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation acceleration. Its memory protection strategy includes flash lock bits and password-protected register access to prevent unauthorized code readout or modification.

It features a programmable on-chip oscillator with ±2% short-term deviation (DS §128), configurable PLL for clock scaling, and three independent 16-bit timers (Timer 0/1/2), Timer 21, CCU6 for motor control PWM generation, and MultiCAN with 32 message objects supporting both transmit and receive buffering with hardware filtering.

FAQ

Does XC886C8FFA5VACKXUMA1 support JTAG debugging?

Yes, it implements IEEE 1149.1-compliant JTAG interface with OCDS (On-Chip Debug Support) for full boundary-scan, real-time trace, and non-intrusive breakpoint debugging. The JTAG ID register is located at address 0xF000 (DS §103), and TCK/TMS/TDI/TDO pins map to P3.4–P3.7 in dedicated debug mode.

What is the maximum operating frequency of the XC800 core?

The XC800 core runs at up to 26.67 MHz system clock (with PLL enabled), delivering 13.33 MIPS performance. Without PLL, the maximum frequency is 20 MHz using external crystal or internal oscillator (DS §128–129). Core clock is derived from programmable PLL with 1× to 4× multiplication factor.

Can the ADC operate independently of CPU intervention?

Yes, the ADC supports hardware-triggered conversions via CCU6, Timer 2, or external event pins, with automatic result storage in dedicated data registers and optional interrupt generation upon completion. Scan mode allows sequential conversion of up to 8 channels without software loop overhead (DS §101–102).

Is the Boot ROM field-programmable or permanently masked?

The 12 KB Boot ROM is mask-programmed during wafer fabrication and cannot be modified in-system or reprogrammed. It contains Infineon's certified bootloader supporting Flash programming via UART or CAN, and is protected against read-out by hardware lock bits (DS §21–22).
