Infineon Technologies XC87813FFA5VACKXUMA1

Overview

XC87813FFA5VACKXUMA1 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 at two clocks per machine cycle. It integrates 52 KB Flash, 8 KB Boot ROM, 3 KB XRAM, and 256 B RAM, with dual-voltage operation (core at 2.5 V, I/O at 5.0 V), and targets automotive body control modules requiring LIN and CAN communication.

For engineers reviewing the XC87813FFA5VACKXUMA1 datasheet, XC87813FFA5VACKXUMA1 pinout, XC87813FFA5VACKXUMA1 application, or XC87813FFA5VACKXUMA1 equivalent, key selection criteria include its integrated MultiCAN controller, LIN protocol support, 10-bit 8-channel ADC, CCU6 timer for motor control, and on-chip debug via JTAG/OCDS.

Technical Context

The XC87813FFA5VACKXUMA1 implements a two-clock-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory architecture separates core logic (2.5 V) from I/O ports (5.0 V), enabled by an embedded voltage regulator.

It features a MultiCAN module supporting up to 64 message objects, a CCU6 unit with three 16-bit capture/compare timers for 3-phase motor control, and dual UARTs (UART/UART1) with LIN header generation capability - all operating under a unified clock generation unit with PLL and multiple power-saving modes.

FAQ

What is the maximum operating frequency of the XC87813FFA5VACKXUMA1?

The XC87813FFA5VACKXUMA1 achieves a maximum system clock frequency of 26.67 MHz using its internal PLL, driven by an external crystal up to 20 MHz. This frequency is sustained across the full −40 °C to +105 °C automotive temperature range, with timing validated per AC parameter Table 4.3 in the V1.5 datasheet.

Does this MCU support in-system programming (ISP) via UART?

Yes - the XC87813FFA5VACKXUMA1 supports UART-based bootloader programming through UART0 (P3.0/P3.1) using the on-chip Boot ROM. The process requires no external debugger and uses a defined command protocol documented in Section 3.7.2 (Booting Scheme) of the datasheet, with flash sector protection configurable via password register.

Is the CCU6 unit capable of generating complementary PWM outputs with programmable dead time?

Yes - the CCU6 unit provides three independent 16-bit timers with dedicated capture/compare channels, each supporting complementary PWM output pairs with hardware-configurable dead-time insertion (1–128 clock cycles). This is explicitly detailed in Section 3.20 and confirmed in Figure 3.20-1 of the datasheet for motor control applications.

What is the ADC's effective resolution and sampling rate in continuous conversion mode?

In continuous conversion mode with internal clock source, the ADC achieves 10-bit resolution with a maximum sampling rate of 100 kSPS (10 µs conversion time), as specified in Section 4.2.3 and Table 4.2.3-1. Accuracy is guaranteed to ±2 LSB INL/DNL across the full temperature range when using the internal 2.5 V reference.
