Product details
Overview
XC866L2FRA5VBELXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core (8051-compatible), featuring 8 KB Flash, 256 B RAM, 512 B XRAM, and integrated peripherals including a 10-bit 8-channel ADC, three 16-bit timers, UART, SSC, CCU6 PWM unit, and on-chip debug support. It operates with core logic at 2.5 V (via embedded voltage regulator) and I/O at 3.3 V or 5.0 V, targeting automotive body electronics and industrial motor control.
For engineers reviewing the XC866L2FRA5VBELXUMA1 datasheet, XC866L2FRA5VBELXUMA1 pinout, XC866L2FRA5VBELXUMA1 application, or XC866L2FRA5VBELXUMA1 equivalent, key selection criteria include its PG-TSSOP-38 package, -40 °C to +150 °C operating temperature, LIN-capable UART, hardware-based memory protection, and boot ROM-resident monitor for in-system debugging.
Technical Context
The XC866L2FRA5VBELXUMA1 implements a two-clock-per-machine-cycle 8051-compatible architecture enabling zero-wait-state memory access. Its memory subsystem includes 8 KB Flash with sectorized programming, 256 B RAM, 512 B XRAM, and 8 KB Boot ROM containing 1 KB monitor ROM and 64 B monitor RAM for debug operations.
Peripherals are tightly coupled to the core via dedicated SFRs and interrupt vectors: the CCU6 provides 16-bit capture/compare for motor control PWM; the 10-bit ADC supports configurable conversion sequences across eight analog inputs; and the LIN-compliant UART supports header transmission per ISO 9141-2/ISO 14230-1 standards.

FAQ
Is XC866L2FRA5VBELXUMA1 qualified for automotive applications?
Yes. It is AEC-Q100 qualified for Grade 0 (−40 °C to +150 °C) and specified for automotive body electronics per Infineon's SAL-XC866 datasheet. Its embedded voltage regulator, brownout detection, and LIN-capable UART meet functional safety requirements for non-safety-critical vehicle subsystems.
Does XC866L2FRA5VBELXUMA1 support in-system programming (ISP)?
Yes. The device supports ISP via UART using the on-chip 8 KB Boot ROM, which contains a monitor program accessible through standard serial commands. No external programmer is needed - firmware updates can be performed in the target system using a simple RS232 or TTL-level interface.
What is the role of the CCU6 module in this microcontroller?
The CCU6 (Capture/Compare Unit 6) is a dedicated 16-bit PWM generator with six output channels, dead-time control, and emergency shutdown input. It is used primarily for precise 3-phase motor commutation, LED dimming, or digital power supply control - offloading timing-critical tasks from the CPU.
Can XC866L2FRA5VBELXUMA1 operate without an external crystal?
Yes. It includes an on-chip RC oscillator usable as a clock source, though with ±10% frequency tolerance. For LIN communication or precise timing, Infineon recommends an external crystal (1–20 MHz) connected to OSC1/OSC2 - the PLL then multiplies this to achieve stable core clock frequencies up to 26.67 MHz.
