Product details
Overview
SAF-XC878-13FFI5VAC from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the 8051 instruction set. It integrates 52 KB Flash, 3 KB XRAM, 256 B RAM, and 8 KB Boot ROM; features a 10-bit 8-channel ADC, MultiCAN interface, CCU6 capture/compare unit, and embedded 2.5 V voltage regulator for core logic. Used in automotive body control modules requiring real-time LIN/CAN communication and analog sensor interfacing.
For engineers reviewing the SAF-XC878-13FFI5VAC datasheet, SAF-XC878-13FFI5VAC pinout, SAF-XC878-13FFI5VAC application, or SAF-XC878-13FFI5VAC equivalent, key selection criteria include Flash size (52 KB), dual supply domains (3.3/5.0 V I/O, 2.5 V core), MultiCAN v2.0B compliance, CCU6 timer resolution (16-bit), and on-chip debug support via JTAG.
Technical Context
The SAF-XC878-13FFI5VAC implements a two-clock-per-machine-cycle XC800 core derived from the 8051 architecture, enabling zero-wait-state memory access. It supports dual supply operation: I/O ports operate at 3.3 V or 5.0 V while the core runs at 2.5 V via an integrated voltage regulator.
Functional units include a 10-bit 8-channel ADC with configurable conversion sequence, MultiCAN controller compliant with ISO 11898-1:2003 (CAN 2.0B), and CCU6 - a 16-bit capture/compare unit optimized for motor control timing with three independent channels and dead-time insertion capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 (8051-compatible), 2 clocks/machine cycle → enables zero-wait-state execution from internal Flash/XRAM. |
| Flash Memory | 52 KB with memory protection → supports secure boot code storage and firmware updates with write-locking per sector. |
| RAM / XRAM | 256 B on-chip RAM + 3 KB XRAM → provides fast data access for real-time control stacks and buffer-intensive peripherals. |
| ADC Resolution | 10-bit, 8-channel → delivers ±1 LSB INL/DNL for accurate temperature, voltage, and current sensing in automotive ECUs. |
| CAN Interface | MultiCAN v2.0B (2 nodes) → enables concurrent CAN message handling for body domain networks with hardware mailbox buffering. |
| CCU6 Timer | 16-bit capture/compare unit with 3 channels → supports PWM generation, edge-triggered capture, and dead-time control for 3-phase motor drivers. |
| Supply Configuration | I/O: 3.3 V or 5.0 V; Core: 2.5 V (integrated regulator) → simplifies power design by eliminating external core LDO in cost-sensitive automotive modules. |

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-XC886-13FRA5VAC | 64 KB Flash, same XC800 core, identical VQFN-48 package, but includes External Bus Interface (EBI) - not present in SAF-XC878. | Required when external SRAM or display controller interfacing is needed; SAF-XC878 lacks EBI. | Select SAF-XC886 only if external memory expansion or parallel peripheral interfacing is mandatory. |
| TLE9842-2QX | ARM Cortex-M0 core, integrated H-Bridge drivers, 128 KB Flash, 12 KB RAM - higher performance and integration, but different architecture and toolchain. | Suitable for next-generation motor control where integrated gate drivers reduce BOM count; not drop-in compatible. | Choose TLE9842 for new designs targeting higher integration and ARM ecosystem; avoid for 8051 code migration paths. |
Compared with SAF-XC886-13FRA5VAC, SAF-XC878-13FFI5VAC trades external bus capability for lower cost and reduced pin count; versus TLE9842-2QX, it offers mature 8051 tooling and smaller Flash footprint ideal for incremental ECU upgrades.

FAQ
What is the maximum operating frequency of the SAF-XC878-13FFI5VAC?
The SAF-XC878-13FFI5VAC operates at up to 26.7 MHz system clock frequency, derived from its internal PLL which multiplies the external crystal oscillator (1–20 MHz range) or RC oscillator. This yields a 13.35 MHz CPU clock due to the two-clock-per-cycle architecture, enabling 6.675 million instructions per second (MIPS) throughput.
Does this microcontroller support in-circuit debugging?
Yes, the SAF-XC878-13FFI5VAC includes full on-chip debug support via IEEE 1149.1 JTAG interface, with dedicated TCK, TMS, TDO, and TDI pins. It supports breakpoints, single-stepping, register inspection, and Flash programming through standard Infineon DAS tools and third-party debuggers compatible with XC800 cores.
Can the ADC operate independently of the CPU during sleep modes?
No - the 10-bit ADC requires active CPU clocking and cannot perform conversions in Power-down or Stop modes. However, it can operate in Idle mode with CPU halted, triggered by timer or external event, allowing low-power background sensing while preserving RAM contents and peripheral states.
Is the MultiCAN module compatible with CAN FD?
No - the MultiCAN controller in SAF-XC878-13FFI5VAC implements ISO 11898-1:2003 (Classical CAN 2.0B) only, supporting up to 1 Mbit/s bit rate and 11-bit standard identifiers. It does not support CAN FD frame format, data rate switching, or extended payload lengths beyond 8 bytes.
