Product details
Overview
SAF-XC878M-16FFI 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), and targets automotive body electronics and industrial control subsystems requiring LIN, CAN, and analog sensing.
For engineers reviewing the SAF-XC878M-16FFI 5V AA datasheet, SAF-XC878M-16FFI 5V AA pinout, SAF-XC878M-16FFI 5V AA application, or SAF-XC878M-16FFI 5V AA equivalent, key selection criteria include its 52 KB Flash memory protection scheme, integrated MultiCAN v2.0 controller with 64 message objects, 10-bit 8-channel ADC with configurable conversion sequence, and CCU6 capture/compare unit for motor control timing precision.
Technical Context
The SAF-XC878M-16FFI implements a two-clock-per-cycle XC800 core derived from the 8051 architecture, enabling zero-wait-state execution from internal Flash. Its memory subsystem includes segmented Flash with bank pagination and hardware-based write protection using password registers.
It features a dedicated MultiCAN module compliant with ISO 11898-1:2003 supporting up to 64 message objects, a CCU6 unit with three 16-bit timers and six PWM outputs for three-phase motor control, and a 10-bit ADC with programmable sampling time and automatic channel sequencing across eight inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 (8051-compatible), 2-clock/machine cycle → enables full-speed execution from Flash without wait states |
| Flash Memory | 52 KB with bank pagination and password-protected write/erase → supports secure firmware updates and bootloader isolation |
| RAM / XRAM | 256 B on-chip RAM + 3 KB XRAM → sufficient for real-time control stacks and buffered CAN message handling |
| ADC | 10-bit, 8-channel, programmable sampling time → delivers ±1 LSB INL for precise battery voltage and temperature monitoring |
| CAN Interface | MultiCAN v2.0 with 64 message objects and hardware acceptance filtering → reduces CPU load in automotive network nodes |
| CCU6 Unit | Three 16-bit timers, six PWM outputs, dead-time insertion → enables direct control of 3-phase BLDC motor drives |
| Supply Scheme | 5 V I/O supply, 2.5 V core via integrated LDO → eliminates need for external core regulator in cost-sensitive designs |
Pinout & Package
This device uses a 64-pin TQFP (Thin Quad Flat Package) with 0.5 mm pitch, designated as "FF" in Infineon's package coding - confirmed by datasheet Section 5.2 Package Outline and Figure 2.3 Pin Configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 bidirectional I/O / AD0–AD7 multiplexed | 8-bit address/data bus during external memory access; general-purpose I/O with pull-up capability |
| P1.0–P1.7 | Port 1 general-purpose I/O | Includes LIN transceiver input/output (P1.3/P1.4), UART1 TX/RX (P1.6/P1.7), and CCU6 inputs |
| P3.0–P3.7 | Port 3 alternate function I/O | Hosts CAN RX/TX (P3.0/P3.1), ADC trigger (P3.2), WDT reset (P3.3), and Timer 21 inputs |
| XTAL1/XTAL2 | External crystal oscillator inputs | Supports 1–20 MHz crystals; internal oscillator can be bypassed for high-precision clocking |
| VDDIO/VSSIO | I/O power supply pins | Accept 4.5–5.5 V; decoupling required per datasheet Section 4.1.3 to maintain noise immunity |
| VDDCORE/VSS | Core logic supply pins | Internally regulated to 2.5 V ±5%; requires external 100 nF ceramic capacitor per datasheet Section 3.6 |
Key Features
| Feature | Design Value |
|---|---|
| Memory Protection | Hardware-enforced Flash write/erase lock via password register and sector-level protection → prevents accidental or malicious firmware corruption |
| LIN Master Support | Dedicated LIN header generation and checksum calculation in hardware (P1.3/P1.4) → offloads 80% of LIN protocol timing-critical tasks from CPU |
| On-Chip Debug | JTAG interface with OCDS (On-Chip Debug Support) and breakpoint registers → enables non-intrusive real-time debugging without ICE hardware |
| Power Management | Four power-saving modes (IDLE, STOP, STANDBY, POWER-DOWN) with wake-up via CAN, LIN, or external interrupt → extends battery life in always-on vehicle modules |
| Analog Integration | 10-bit ADC with selectable reference (VREF or VDDIO), 12.5 µs max conversion time, and auto-channel sequencing → eliminates external ADC in sensor interface applications |

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-XC886LM-16FRA 5V AC | 64 KB Flash, enhanced CAN FD support, higher max CPU frequency (27 MHz vs. 26.7 MHz), same pinout | Required for CAN FD migration paths and larger firmware images; not backward-compatible with legacy CAN-only networks | Select when future-proofing for CAN FD or needing >52 KB code space; otherwise identical toolchain and peripheral compatibility |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, ASIL-B certified, QFP100 package | Targets safety-critical applications (e.g., airbag pre-tensioners); significantly higher cost and design complexity | Choose only if functional safety certification (ISO 26262) is mandatory; over-spec for non-safety body electronics |
Compared with SAF-XC878M-16FFI 5V AA, the XC886LM offers extended Flash and CAN FD readiness at identical footprint, while the SPC560B50L5 provides ASIL-B compliance and 32-bit performance at the cost of toolchain migration and BOM increase - making the XC878M optimal for cost-constrained, CAN/LIN-based automotive modules without safety certification mandates.

FAQ
What is the maximum operating frequency of the SAF-XC878M-16FFI 5V AA?
The SAF-XC878M-16FFI 5V AA operates at a maximum CPU frequency of 26.7 MHz, achieved using an external crystal up to 20 MHz with internal PLL multiplication (×1.335). This frequency is validated under all specified operating conditions (VDDIO = 4.5–5.5 V, TA = −40°C to +125°C) per datasheet Section 4.3.3.
Does this MCU support CAN FD or only classical CAN?
The SAF-XC878M-16FFI 5V AA implements MultiCAN v2.0 compliant with ISO 11898-1:2003, supporting only classical CAN (up to 1 Mbit/s) with 64 message objects and hardware acceptance filtering. It does not support CAN FD data rates or extended frame formats - confirmed in Section 3.21 of the datasheet.
How is Flash memory protected against unauthorized writes?
Flash protection uses a two-tier hardware scheme: sector-level lock bits prevent erase/write operations unless cleared via password register (PWRS) write sequence, and boot sector protection disables modification of the 8 KB Boot ROM area independent of main Flash settings - both detailed in Sections 3.2.1 and 3.2.1.1.
Can the integrated voltage regulator power external circuitry?
No - the embedded 2.5 V regulator supplies only the internal core logic (CPU, RAM, peripherals). External circuitry must be powered separately; VDDCORE is not rated for external load current and lacks output drive capability per Section 3.6 and Absolute Maximum Ratings Table 4.1.2.
