Product details
Overview
SAF-XC878-16FFI 3V3 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 (3.3 V I/O, 2.5 V core via embedded regulator). It targets automotive body electronics requiring LIN, CAN, and analog sensing.
For engineers reviewing the SAF-XC878-16FFI 3V3 AA datasheet, SAF-XC878-16FFI 3V3 AA pinout, SAF-XC878-16FFI 3V3 AA application, or SAF-XC878-16FFI 3V3 AA equivalent, this page delivers verified electrical specs, package mapping, functional role in LIN/CAN nodes, ADC timing behavior, and validated drop-in alternatives for production design continuity.
Technical Context
The SAF-XC878-16FFI 3V3 AA implements a two-clock-per-machine-cycle XC800 core derived from the 8051 architecture, enabling zero-wait-state memory access. It features an integrated 2.5 V voltage regulator supplying the core while supporting 3.3 V I/O operation across eight digital ports.
It includes dedicated hardware peripherals: MultiCAN controller (2 channels), LIN protocol support (header generation and sync detection), 10-bit 8-channel ADC with configurable conversion sequence, and CCU6 for motor control PWM generation. Clocking supports internal RC oscillator (±2% accuracy) and external crystal up to 26 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 (8051-compatible), 2-clock/machine cycle → enables deterministic 16 MHz max CPU throughput without wait states |
| Flash Memory | 52 KB with memory protection → supports secure bootloader partitioning and field firmware updates |
| RAM / XRAM | 256 B on-chip RAM + 3 KB XRAM → sufficient for real-time LIN/CAN stack execution and sensor data buffering |
| ADC Resolution | 10-bit, 8-channel, programmable sampling rate → meets automotive temperature and battery voltage monitoring requirements |
| Communication Interfaces | MultiCAN (2 channels), UART/UART1, SSC, LIN → enables full vehicle network node functionality with redundancy |
| Supply Configuration | 3.3 V I/O supply, 2.5 V core (internally regulated) → simplifies board power design and ensures noise-immune core operation |
| Operating Temperature | −40 °C to +125 °C → qualified for under-hood automotive applications per AEC-Q100 Grade 1 |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 bidirectional I/O | Open-drain capable; multiplexed with address/data bus for external memory expansion |
| P1.0–P1.7 | Port 1 bidirectional I/O | Dedicated to LIN TX/RX, CAN RX/TX, and timer capture inputs - no address bus function |
| P3.0–P3.7 | Port 3 bidirectional I/O | Includes UART1 TXD/RXD, ADC trigger, WDT reset, and external interrupt inputs |
| XTAL1/XTAL2 | Crystal oscillator input/output | Supports 1–26 MHz crystals; internal RC oscillator available as fallback clock source |
| VDDIO / VSSIO | I/O power supply / ground | 3.3 V tolerant; separate from core VDD (2.5 V) to isolate noisy digital I/O from sensitive core logic |
| VDDCORE / VSS | Core power supply / ground | Internally regulated 2.5 V supply; decoupling required per datasheet layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Embedded Voltage Regulator | Generates stable 2.5 V core supply from 3.3 V rail - eliminates need for external LDO and reduces BOM count |

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 |
|---|---|---|---|
| SAF-XC886-16FFI 3V3 AA | 64 KB Flash, enhanced CAN FD support, same pinout and voltage specs | Better suited for future-proofed designs requiring CAN FD diagnostics or larger firmware images | Select when CAN FD capability or >52 KB Flash is required; software migration path is minimal |
| TLE9842-2QX | ARM Cortex-M0 core, integrated H-Bridge drivers, 128 KB Flash, 32 KB RAM | Higher integration for motor control - replaces external gate drivers and reduces PCB area | Choose for new designs targeting higher performance and integrated power stage; not pin-compatible |
Compared with SAF-XC878-16FFI 3V3 AA, the XC886 offers extended Flash and CAN FD readiness within identical packaging, while the TLE9842 provides ARM-based scalability and embedded power drivers - making it suitable for next-generation motor control nodes where cost-per-function and integration outweigh legacy 8051 compatibility needs.

FAQ
Is SAF-XC878-16FFI 3V3 AA qualified for automotive use?
Yes. It is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C ambient), with built-in voltage supervisor, watchdog timer, and memory protection features required for automotive body electronics. Its qualification documentation is published in Infineon's official product change notices and reliability reports.
Does it support external memory expansion?
Yes. Port 0 serves as a multiplexed address/data bus (AD0–AD7), and Port 2 provides upper address bits (A8–A15) when external memory mode is enabled. The MCU supports up to 64 KB external program/data memory with programmable wait-state control.
What debug interfaces does it provide?
It features On-Chip Debug Support (OCDS) via JTAG interface (TCK/TMS/TDI/TDO/TRST), supporting full breakpoint, single-stepping, and memory inspection. No external debug probe is needed beyond standard JTAG cabling and compatible IDEs like DAVE™ or Keil µVision.
Can it operate without an external crystal?
Yes. It includes an internal RC oscillator (12 MHz nominal, ±2% accuracy over temperature) usable as main clock source. External crystal (1–26 MHz) is optional and recommended only for applications requiring tighter timing accuracy, such as LIN baud-rate stability.
