Product details
Overview
SAX-XC878C-13FFA 5V AA 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, 3 KB XRAM, 256 B RAM, and 8 KB Boot ROM, with dual-voltage operation (5 V I/O, 2.5 V core via embedded regulator). It targets automotive body electronics and industrial control where LIN, CAN, and high-precision ADC timing are required.
For engineers reviewing the SAX-XC878C-13FFA 5V AA datasheet, SAX-XC878C-13FFA 5V AA pinout, SAX-XC878C-13FFA 5V AA application, or SAX-XC878C-13FFA 5V AA equivalent, key selection criteria include its 16-bit CCU6 timer for motor control PWM generation, MultiCAN 2.0B interface, 10-bit 8-channel ADC with configurable conversion sequence, and on-chip debug support via JTAG/OCDS.
Technical Context
The XC878C implements a dual-supply architecture: 5 V supplies I/O ports and external interfaces while an integrated voltage regulator delivers a stable 2.5 V to the XC800 core, enabling noise-immune digital operation without external LDOs. Its memory protection strategy includes Flash bank locking and password-protected write access to prevent accidental firmware corruption.
It features a dedicated CORDIC coprocessor for real-time trigonometric computation and an MDU for fast integer multiplication/division - both accessible via special function registers. The interrupt system supports 32 vectored sources with programmable priority levels, and reset behavior is governed by a multi-source control unit covering power-on, watchdog, and external reset inputs.

FAQ
What is the maximum operating frequency of the SAX-XC878C-13FFA 5V AA core?
The XC800 core operates at up to 26 MHz, derived from an internal PLL locked to an external crystal (1–20 MHz). This frequency is sustained without wait states due to the two-clock-per-machine-cycle architecture, enabling deterministic instruction timing critical for motor control loops.
Does this microcontroller support LIN 2.1 protocol natively?
Yes - the SAX-XC878C-13FFA 5V AA includes dedicated LIN hardware support in its UART1 module, including automatic header detection, checksum generation/verification, and wakeup frame handling per LIN 2.1 specification, eliminating software bit-banging overhead.
Can the on-chip ADC be triggered synchronously with PWM signals?
Yes - the ADC supports hardware triggering from CCU6 timer events, allowing precise sampling aligned to PWM edges or center-aligned periods. This capability is documented in Section 3.22.2 (ADC Conversion Sequence) of the datasheet and used in motor current sensing applications.
Is there a qualified version of this part for automotive AEC-Q100 Grade 2?
Yes - the "AA" suffix denotes AEC-Q100 Grade 2 qualification (−40 °C to +105 °C ambient), confirmed in Infineon's quality declaration document (Section 5.3 of DS V1.5). Full qualification data, including HTOL and ESD test reports, is available under NDA from Infineon.
