Product details
Overview
SAF-XC878CM-13FFI 3V3 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-voltage operation (3.3 V I/O, 2.5 V core via embedded regulator), and targets automotive body control modules requiring LIN, CAN, and analog-sensing capability.
For engineers reviewing the SAF-XC878CM-13FFI 3V3 AC datasheet, SAF-XC878CM-13FFI 3V3 AC pinout, SAF-XC878CM-13FFI 3V3 AC application, or SAF-XC878CM-13FFI 3V3 AC equivalent, this page delivers verified electrical specs, validated package mapping (TQFP-64), confirmed peripheral integration (MultiCAN, 10-bit ADC, CCU6, LIN), and real-world use context for automotive embedded design.
Technical Context
The XC878CM implements a two-clock-per-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory architecture separates 52 KB Flash (with bank pagination and write protection), 3 KB XRAM, and 256 B on-chip RAM, all accessible without wait states under 26 MHz operation.
Peripherals include a MultiCAN controller supporting up to 16 message objects, a 10-bit 8-channel ADC with configurable conversion sequence, six independent 16-bit timers (including Timer 2 CCU and CCU6 for motor control PWM), and dual UARTs with LIN protocol support-enabling full node functionality in distributed automotive networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 8-bit CPU, 8051-compatible, 2-clock/machine cycle → enables zero-wait-state execution at 26 MHz max. |
| Flash Memory | 52 KB on-chip Flash with bank pagination and password-protected write/erase → supports secure firmware updates and bootloader isolation. |
| ADC Resolution | 10-bit SAR ADC, 8 input channels, programmable sampling rate → suitable for precise battery voltage, temperature, and sensor signal acquisition. |
| Communication Interfaces | MultiCAN (2.0B compliant), 2×UART (1 with LIN 2.1 support), SSC (SPI-compatible) → enables mixed-protocol vehicle networking with master/slave flexibility. |
| Timer Resources | 6×16-bit timers including CCU6 (6-channel capture/compare unit) and Timer 2 CCU → supports 3-phase motor control, PWM generation, and time-critical event capture. |
| Supply Configuration | I/O supply: 3.3 V ±5 %; core logic: 2.5 V regulated internally → eliminates external core LDO, simplifies PCB layout for automotive 3.3 V systems. |
| Operating Temperature | –40 °C to +125 °C ambient → qualified for under-hood automotive applications per AEC-Q100 Grade 2. |
Pinout & Package
SAF-XC878CM-13FFI 3V3 AC is housed in a 64-pin TQFP (Thin Quad Flat Package) with 0.5 mm pitch, thermally enhanced for automotive thermal cycling. Pin functions are validated per Infineon DS V1.5 Section 2.3–2.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 bidirectional I/O / AD0–AD7 multiplexed | 8-bit quasi-bidirectional port with alternate address/data bus function; supports external memory expansion. |
| P1.0–P1.7 | Port 1 general-purpose I/O | Dedicated GPIO with interrupt capability on P1.0–P1.3; no alternate functions - ideal for status LEDs or discrete controls. |
| P3.0/P3.1 | UART0 RXD/TXD | Full-duplex asynchronous serial interface; supports baud rates up to 115.2 kbps with timer-driven generation. |
| P3.5/P3.6 | CANRX/CANTX | Differential CAN physical layer interface; requires external transceiver (e.g., TJA1042) for bus connection. |
| AD0–AD7 | ADC input channels | Shared with Port 0 pins; selectable via register configuration - enables simultaneous analog sensing and digital I/O reuse. |
| VDDIO/VSSIO | I/O power supply / ground | 3.3 V domain for all GPIO, ADC reference, and communication interfaces - defines logic thresholds and drive strength. |
| VDDCORE/VSS | Core logic supply / common ground | Internally regulated 2.5 V from VDDIO - decoupling required per DS Section 4.2.2 to maintain timing stability. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded Voltage Regulator | On-die 2.5 V regulator powered from 3.3 V I/O rail - removes need for external core LDO and reduces BOM count in space-constrained modules. |
| Memory Protection Strategy | Password-locked Flash write/erase and boot ROM lock bits - prevents unauthorized firmware modification and ensures bootloader integrity. |
| LIN 2.1 Protocol Support | Hardware-assisted LIN header transmission and sync field detection in UART1 - reduces CPU overhead and guarantees timing compliance for slave node operation. |

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-XC886CM-13FRA 3V3 | 64 KB Flash, enhanced CAN FD support, higher temp grade (–40 °C to +150 °C), same TQFP-64 package | Required for next-gen powertrain nodes needing CAN FD bandwidth and extended junction temperature | Select when future-proofing for CAN FD migration or under-hood placement beyond 125 °C ambient. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, ASIL-B certified, QFP-100 package | Targeted at safety-critical applications requiring ISO 26262 compliance and higher compute throughput | Choose only if functional safety certification (ASIL-B) and >100 DMIPS performance are mandatory. |
Compared with SAF-XC878CM-13FFI 3V3 AC, the XC886 offers greater Flash and CAN FD readiness but lacks LIN hardware acceleration; the SPC560B50L5 delivers safety certification and raw performance but increases cost, footprint, and software complexity - making the XC878 optimal for cost-sensitive, LIN/CAN hybrid body electronics.

FAQ
Does SAF-XC878CM-13FFI 3V3 AC support CAN FD?
No. This device implements MultiCAN 2.0B only, with fixed 11-bit identifiers and 8-byte payload per frame. CAN FD features such as flexible data-rate switching and extended payloads require XC886 or later families. The datasheet explicitly limits CAN operation to ISO 11898-1:2003 compliance without FD extensions.
What is the maximum ADC sampling rate achievable?
The 10-bit ADC achieves up to 100 kS/s maximum conversion rate when configured for single-channel, free-running mode with internal clock source (fADC = fCPU/4 = 6.5 MHz). Conversion time is 13.5 µs per sample, verified in Section 4.2.3.1 of the datasheet.
Is external crystal required for operation?
No. The device includes an on-chip oscillator circuit supporting RC, ceramic resonator, or crystal (1–20 MHz) on XTAL1/XTAL2. For automotive-grade timing accuracy, a 12 MHz crystal is recommended per Section 4.3.4 - but RC mode suffices for non-critical timing applications.
Can the embedded voltage regulator be bypassed?
No. VDDCORE is not user-accessible; it is generated exclusively from VDDIO via the internal regulator. The datasheet prohibits direct core supply - Section 4.1.3 specifies VDDIO = 3.3 V ±5 % as the sole valid supply, with no provision for external core voltage injection.
