SAK-XC2080M-104F80LAA Overview
What is a 16-bit automotive microcontroller? A 16-bit MCU is a microcontroller whose central processing unit operates on a 16-bit data path, sitting in the hierarchy between 8-bit controllers (e.g., 8051) and 32-bit application processors (e.g., ARM Cortex-M). The XC2000 family specifically targets powertrain, chassis, body, and driver-assistance systems where deterministic interrupt latency, on-chip CAN/LIN connectivity, and single-voltage Flash operation matter more than raw MHz. Within Infineon's portfolio it sits below TriCore AURIX and above 8-bit XC800 devices.
Key features include the C166SV2 CPU with 5-stage pipeline, 832 KB Flash supporting in-application programming, 82 KB SRAM with parity, and a peripheral set including up to 6 CAN nodes (TTCAN-capable), LIN, FlexRay, and a 12-bit ADC with up to 16 channels. The device integrates a DMA controller, capture/compare units, and a MultiCAN module supporting ISO 11898-1.
The architecture uses a von Neumann-style memory model with 24-bit linear addressing up to 16 MB, plus a 16 KB on-chip code SRAM that can be mapped for cache or direct execution. The on-chip voltage regulator permits single 5V supply operation, simplifying automotive 12V board design after a downstream pre-regulator.
Typical applications include automotive body control modules, electric power steering, gateway ECUs, industrial automation controllers, and CAN node endpoints in vehicle networks. The -104F80LAA suffix indicates 104 MHz CPU capability (bin-limited to 80 MHz), 832 KB Flash, 144-pin LQFP package, and an automotive-grade temperature profile.
When designing with this part, ensure the operating system uses the device's memory protection unit and watchdog correctly. Migration to a newer AURIX TC2xx/TC3xx part is recommended for new designs; the SAK-XC2080M-104F80LAA is now positioned as a legacy continuity-of-supply component through Rochester Electronics and authorized distributors.

Typical Applications
SAK-XC2080M-104F80LAA is suitable for 6 applications: Automotive Body Control Modules (BCM), Automotive Gateway ECU, Industrial Automation Controller, Electric Power Steering (EPS) Assist Controller, CAN Node Endpoint / Sensor Cluster, Continuity-of-Supply Service Replacement for XC2000 Designs.
Automotive Body Control Modules (BCM)
The SAK-XC2080M-104F80LAA's C166SV2 core at 80 MHz and integrated MultiCAN with up to 6 TTCAN nodes make it well suited for body control modules that aggregate door, lighting, and mirror ECUs onto the vehicle CAN backbone. The 832 KB Flash supports full BCM application code with diagnostic UDS stacks (ISO 14229), while 82 KB SRAM handles concurrent CAN message buffers. The 144-pin LQFP exposes enough GPIO for body-domain switch inputs and PWM-driven lamp outputs without external I/O expanders. Operating from 3.0-5.5 V and qualified to -40 C to +125 C, the part directly connects to automotive 12 V rails via a pre-regulator.
Recommended
Automotive Gateway ECU
The SAK-XC2080M-104F80LAA's six MultiCAN nodes plus UART/SPI make it a strong fit for vehicle network gateways that bridge CAN, LIN, and diagnostic buses. The C166SV2 core's deterministic interrupt latency ensures time-critical CAN-to-CAN routing frames are forwarded within OEM-spec deadlines. The 832 KB Flash accommodates routing tables and security libraries, and 82 KB SRAM buffers burst CAN traffic. Hardware CAN filtering and TTCAN synchronization support ISO 11898-1 gateway timing profiles. RoHS compliance and automotive temperature grading suit under-hood or cabin-mounted gateway placements.
Recommended
Industrial Automation Controller
The SAK-XC2080M-104F80LAA's 80 MHz C166SV2, 12-bit ADC, and MultiCAN peripherals suit distributed industrial automation nodes requiring deterministic real-time response. The 832 KB Flash stores Modbus/CANopen protocol stacks plus application logic, while 82 KB SRAM buffers real-time process data. The 144-pin LQFP provides enough GPIO for digital I/O banks and PWM channels driving motor valves or relays. With an industrial-augmented -40 C to +125 C range, the part operates inside cabinets near power stages. Migration path from C166SV2 to AURIX TC234LP-32F200N is direct via the LQFP-144 footprint.
Recommended
Electric Power Steering (EPS) Assist Controller
Although simpler EPS nodes are typically AURIX-based today, the SAK-XC2080M-104F80LAA's deterministic 80 MHz core and MultiCAN with TTCAN make it serviceable for legacy EPS torque-sensor interface modules and steering column ECUs. The 832 KB Flash accommodates steering-angle sensor calibration tables and CAN diagnostic firmware, while the 144-pin LQFP exposes PWM channels for haptic-feedback actuators. Hardware CRC on Flash supports end-of-line signature verification required by OEM EPS suppliers. Engineers maintaining existing XC2000-based EPS designs use this part for service continuity.
Recommended
CAN Node Endpoint / Sensor Cluster
The SAK-XC2080M-104F80LAA's MultiCAN and LIN make it an effective endpoint for distributed sensor clusters such as radar-pedal modules, battery-current shunts, or wheel-speed transmitters reporting over CAN/LIN to a central ECU. The 80 MHz C166SV2 runs sensor-fusion code plus CAN TP layer within 832 KB Flash, leaving 82 KB SRAM for sample buffers. The integrated 12-bit ADC samples analog sensor channels directly, reducing external ADC cost. The 144-pin LQFP supports both analog and digital sensor wiring without multiplexers.
Recommended
Continuity-of-Supply Service Replacement for XC2000 Designs
The SAK-XC2080M-104F80LAA's primary application today is maintaining long-life automotive and industrial programs that have software certified against the C166SV2 toolchain and cannot accept a firmware re-validation. Its 144-pin LQFP keeps PCB redesign off the table, while 832 KB Flash and 82 KB SRAM match prior XC2080M-based BOMs exactly. Rochester Electronics stocks the part for 15+ year service agreements per automotive OEM requirements. Designers are strongly advised to validate and freeze firmware before sourcing the final last-time-buy allocations.

Key Differentiators
- Most modern XC2000 sub-family option in 144-pin LQFP with 832 KB Flash (vs SAK-XC2080N-104F80LAA)
- Full XC2000 family peripheral set including 6 MultiCAN nodes with TTCAN (vs SAF-XC886CM-8FFI5VAC)
- Strategic migration path via LQFP-144 to AURIX TC234LP (vs SAK-TC234LP-32F200N)
Design Notes
The SAK-XC2080M-104F80LAA integrates a 5V core voltage regulator allowing single 3.0-5.5V supply, but at 80 MHz with full peripheral activity the core current can reach approximately 100 mA. Designers should budget a low-ESR 10uF decoupling cap on VCC5 and a 100 nF ceramic on each VCC pin pair. Estimated: power dissipation under full load is roughly 0.5W; a thermal copper pour connected to the LQFP-144 thermal pad is recommended for under-hood placements.
Route the external memory bus signals (address, data, chip-selects) with matched impedance and length-matched within +/- 5 mm to avoid skew at full bus speed. Place 22 ohm series damping resistors on data lines for EMI control. Keep CAN bus traces short and routed as a 120-ohm differential pair per ISO 11898. The 144-pin LQFP has a non-trivial 0.5 mm pitch footprint that requires a 4-layer PCB with via stitching for clean return paths.
Do not assume new design compatibility with XC2000 software: this part is in last-time-buy and Infineon recommends migration to AURIX TC2xx for new designs. Existing XC2080M users must validate firmware against the latest XC2000 errata sheet, especially for MultiCAN TTCAN timing and ADC calibration drift at temperature extremes. The SAK-XC2080M-104F80LAA is not ISO 26262 ASIL qualified by itself; safety claims require system-level measures.
Compliance Information
RoHS compliant per JaronSemi product page. AEC-Q100 status not explicitly stated in provided data; the part is described as automotive-grade with -40 C to +125 C support. No conflict-mineral concerns documented.
