SAF-XC886CM-8FFI5VAC - 8-bit MCU, 32KB Flash, CAN/LIN | Infineon
MPN： SAF-XC886CM-8FFI5VAC ✓ 啟用中SAF-XC886CM-8FFI5VAC 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), and a rich set of peripherals (timers, ADC, communication interfaces) into one package. Within the broader semiconductor taxonomy, an 8-bit MCU belongs to the embedded microcontroller family, itself a sub-category of microprocessors. The XC88x series targets cost-optimized networked nodes in vehicles where CAN/LIN connectivity replaces point-to-point wiring.
Key features of the SAF-XC886CM-8FFI5VAC include on-chip CAN 2.0B-active and LIN slave/master interfaces, an 8-channel 10-bit ADC with successive-approximation conversion, capture/compare unit (CCU6) for motor-control PWM generation, and a multi-purpose timer (T12/T13). The XC88x core uses the XC800 instruction set with a two-stage pipeline, providing predictable interrupt latency suitable for real-time control loops. On-chip oscillator support and a PLL reduce external BOM, while a window watchdog and brown-out detector improve functional safety.
Typical applications include automotive body control modules, HVAC flap and blower actuators, lighting controllers (interior/exterior LED drivers with LIN command interface), instrument cluster sub-modules, and small sensor/ECU nodes in CAN/LIN vehicle networks. The integrated CAN transceiver-less controller is paired with an external CAN PHY such as Infineon's TLE6250G. The device is also suitable for industrial CANopen nodes and LIN sub-bus slaves where deterministic 8-bit performance is acceptable.
A key design consideration when using this part is the 5V supply requirement; designers should provide adequate decoupling (100 nF + 10 uF) near VDD pins and route the analog AVCC separately. For noise-critical ADC conversions, average multiple samples and synchronize conversions with PWM to reduce switching-noise aliasing.

典型應用
SAF-XC886CM-8FFI5VAC 適用於 6 應用s: Automotive Body Control Module, HVAC Flap and Blower Actuator, Exterior Lighting Module with LIN Interface, Instrument Cluster Sub-Module, CANopen Industrial I/O Slave, Small Sensor / ECU Node on CAN/LIN.
Automotive Body Control Module
The SAF-XC886CM-8FFI5VAC fits automotive body controllers because its integrated CAN 2.0B-active controller and LIN 1.3/2.0 interface provide the two dominant in-vehicle networking protocols in a single chip, eliminating external bus controllers. The 32 KB Flash holds typical body-control firmware (RKE, central locking, mirror-fold logic) while the CCU6 PWM unit drives up to six outputs for indicator and lamp control. The industrial temperature grade (-40C to +125C) meets under-hood and cabin thermal requirements.
推薦
HVAC Flap and Blower Actuator
The SAF-XC886CM-8FFI5VAC suits HVAC flap and blower actuators where its CCU6 PWM peripheral generates the complementary PWM signals needed to drive a small BLDC or DC blower motor at variable speed. The 10-bit ADC with 8 channels reads temperature sensors (NTC/PTC) and potentiometer feedback from the user knob, while the on-chip CAN/LIN controller receives set-point commands from the climate control head unit. The 24 MHz core handles the 10 ms control-loop period with margin for soft-start and stall-detection algorithms.
推薦
Exterior Lighting Module with LIN Interface
The SAF-XC886CM-8FFI5VAC drives exterior lighting modules (headlamp level control, tail-lamp, indicator) where the LIN slave interface receives commands from a body controller over a single-wire bus. The CCU6 PWM unit controls LED current via buck-driver or linear regulation, while the 10-bit ADC monitors LED string voltage for open/short detection. The 32 KB Flash accommodates dimming curves, fault logging, and LIN diagnostic services (per LIN 2.0 spec).
推薦
Instrument Cluster Sub-Module
The SAF-XC886CM-8FFI5VAC serves as a sub-MCU in instrument clusters for tell-tale indicators, gauge stepper drive, or secondary display control where a main MCU handles HMI graphics. Its CAN 2.0B interface receives vehicle data from the gateway, while the CCU6 PWM unit drives small stepper motors for gauge pointers. The 32 KB Flash handles tell-tale logic, gauge calibration tables, and CAN diagnostic UDS services; the 1.75 KB RAM is sufficient for these real-time but memory-light tasks.
推薦
CANopen Industrial I/O Slave
The SAF-XC886CM-8FFI5VAC is suitable for industrial CANopen I/O slave modules where its CAN 2.0B controller supports the CANopen DS301 protocol stack with the 8-bit core. The 8-channel 10-bit ADC reads analog sensor inputs (4-20 mA or 0-10 V via external signal conditioning), while digital I/O drives relays or optocouplers. The wide 4.5V to 5.5V supply tolerance accepts industrial 24V-bus-derived rails after regulation, and the -40C to +125C operating range handles factory-floor temperature swings.
推薦
Small Sensor / ECU Node on CAN/LIN
The SAF-XC886CM-8FFI5VAC acts as a leaf-node ECU for tire-pressure monitoring, seat-occupancy detection, or battery-current sensing where the integrated CAN/LIN controller attaches directly to the vehicle sub-bus. The ADC reads the sensor front-end, the PWM drives a small actuator or buzzer, and the LIN interface provides low-cost slave communication. The XC88x core's deterministic interrupt latency ensures sensor readings are timestamped accurately for vehicle-level diagnostics.

主要差異化特點
- On-chip CAN 2.0B active controller plus LIN 1.3/2.0 interface (對比PIC18F46K22-I/ML)
- Deterministic 8-bit XC800 core with two-stage pipeline (對比SAF-XC866-4FRI)
- Single 5V supply with industrial -40C to +125C range (對比PIC18F46K22-I/ML)
設計說明
Estimated: at 24 MHz active and all peripherals on, core current draw is approximately 20-25 mA from VDD. Add a 100 nF ceramic decoupling capacitor plus a 10 uF bulk capacitor on each VDD/VSS pin pair, placed within 5 mm of the package. Route AVCC through a ferrite bead from VDD and add a separate 100 nF + 10 uF on AVCC to reduce ADC switching-noise coupling.
The TQFP-48 package has a theta_JA of approximately 75 C/W on a 4-layer JEDEC test board. Estimated: at 25 mA x 5V = 125 mW active dissipation, junction temperature rise is only 9 C above ambient at 25 C - well within the -40C to +125C industrial operating range. No external heatsink is required for typical body-control applications, but adequate copper pour on VDD/VSS improves thermal margin in sealed enclosures.
Route the XTAL1/XTAL2 traces as short, symmetric differential pairs with grounded guard traces to reduce oscillator pickup. Place the crystal within 5 mm of the MCU and use a 4-layer PCB with continuous ground plane below the oscillator area. Keep the CAN_TX/CAN_RX and LIN_TX/LIN_RX traces away from PWM switching lines to avoid EMI coupling into the bus signals.
Do not leave TESTEN floating - tie it directly to VSS to prevent accidental entry into test mode. Ensure the brown-out detector is enabled in the firmware to guarantee defined startup behavior on power-on. When using the bootstrap loader (BSL) for in-system programming, dedicate the LIN pin as the BSL interface and provide a way to enter BSL mode (typically via a defined LIN message or hardware pin).
