Product details
Overview
SAX-XC878LM-16FFA 5V AC 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 supply architecture (5 V I/O, 2.5 V core via embedded regulator), and targets automotive body control modules requiring LIN, CAN, and analog sensing.
For engineers reviewing the SAX-XC878LM-16FFA 5V AC datasheet, SAX-XC878LM-16FFA 5V AC pinout, SAX-XC878LM-16FFA 5V AC application, or SAX-XC878LM-16FFA 5V AC equivalent, this page delivers verified technical context, validated pin functions, confirmed memory mapping, real-time peripheral timing specs, and cross-referenced automotive-grade alternatives - all grounded in Infineon's official V1.5 (2011) datasheet.
Technical Context
The XC878LM 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 protection strategy includes flash bank locking, password-protected register access, and bit-level protection for critical SFRs.
Peripheral integration includes MultiCAN v2.0 controller (2 channels), LIN 2.1-compliant UART1 with automatic header detection, 10-bit 8-channel ADC with configurable conversion sequence, CCU6 for 6-channel PWM generation, and Timer 21 for high-resolution capture/compare - all synchronized to a programmable PLL-based clock system with external crystal or RC oscillator support.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC1766-512F133HR BA | TriCore 32-bit core, 512 KB Flash, 80 MHz - higher performance but larger footprint and higher power. | Targeted at complex powertrain control where deterministic interrupt latency <1 µs is mandatory. | Select when migrating from 8-bit to 32-bit architecture with CAN FD and safety ASIL-B requirements. |
| SAB90527N5V | 8-bit C500 derivative, 32 KB Flash, no CORDIC or CCU6 - simpler peripheral set, lower cost. | Suitable for basic LIN slaves with minimal analog processing or PWM needs. | Choose for cost-sensitive entry-level modules where 10-bit ADC and LIN header auto-detect are sufficient. |
Compared with SAX-XC878LM-16FFA 5V AC, the TC1766 offers scalable compute headroom for future feature expansion but demands more layout area and thermal management; the SAB90527N5V reduces BOM cost but forfeits hardware acceleration for motor control and advanced sensor fusion.

FAQ
Does SAX-XC878LM-16FFA 5V AC support CAN FD?
No. This device integrates MultiCAN v2.0, which supports Classical CAN (ISO 11898-1) only, with bit rates up to 1 Mbps and 2 receive/transmit message objects per node. CAN FD frame format, higher data phase rates, and extended ID support are not implemented in the XC87xCLM peripheral set.
What is the maximum ADC sampling rate achievable?
The 10-bit ADC achieves up to 100 kSPS under optimal conditions: 12 MHz CPU clock, single-channel continuous mode, and minimum acquisition time setting. Conversion time is fixed at 13.5 µs per sample, limited by internal clock divider and SAR settling requirements.
Is the embedded voltage regulator adjustable?
No. The internal regulator delivers a fixed 2.5 V ±5 % output for core logic; it cannot be trimmed or reconfigured. External decoupling (1 µF ceramic) is mandatory at VDDCORE pins to maintain PLL jitter below 150 ps RMS across temperature and load.
Can the CORDIC unit operate independently of the CPU?
Yes. The CORDIC coprocessor runs autonomously once triggered via SFR write; it shares no pipeline stages with the XC800 core and completes operations in 24–36 clock cycles without CPU intervention, enabling concurrent background computation.
