Product details
Overview
SAK-XC2785X-72F80L AA from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Base Line family, featuring an 80 MHz CPU with 12.5 ns instruction cycle, 832 KB on-chip Flash, dual 10-bit ADCs (24 channels, <1 µs conversion), and integrated MultiCAN Rev. 2.0B (2 nodes, 64 message objects). It targets automotive powertrain control and industrial motor drives requiring deterministic real-time response.
For engineers reviewing the SAK-XC2785X-72F80L AA datasheet, SAK-XC2785X-72F80L AA pinout, SAK-XC2785X-72F80L AA application, or SAK-XC2785X-72F80L AA equivalent, this page delivers verified electrical specs, validated peripheral timing, package-mapped I/O assignment, and functionally matched alternatives for ECU and inverter firmware development.
Technical Context
The XC2785X implements a C166-compatible five-stage pipeline CPU with MPU, supporting zero-cycle jumps, one-cycle MAC, and background 32/16-bit division in 21 cycles. Its memory subsystem includes 8 KB SBRAM, 2 KB DPRAM, up to 32 KB PSRAM, and ECC-protected 832 KB Flash.
Peripheral integration centers on real-time control: two synchronizable 10-bit ADCs (24 ch, <1 µs), CCU6x units for flexible PWM generation, CAPCOM2 (16 ch), GPT12E (5 timers), and MultiCAN with gateway capability across two CAN nodes - all clocked via programmable PLL or external crystal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 80 MHz - enables 12.5 ns instruction cycle for deterministic real-time loop execution in motor control. |
| Flash Memory | 832 KB - sufficient for complex automotive firmware with boot loader, application, and calibration data. |
| ADC Resolution & Speed | 10-bit, <1 µs conversion - supports high-fidelity current/voltage sampling in PMSM FOC algorithms. |
| CAN Nodes | 2 independent CAN 2.0B interfaces - enables dual-bus communication for engine + transmission ECUs or gateway routing. |
| I/O Lines | Up to 119 GPIO - provides dedicated PWM outputs, analog inputs, and digital signals for sensor/actuator interfacing. |
| Supply Voltage | 3.0 V to 5.5 V - compatible with automotive battery voltage fluctuations without external regulation. |
| Package | 144-pin LQFP, 0.5 mm pitch - standard surface-mount footprint for industrial PCB assembly and thermal management. |
Pinout & Package
SAK-XC2785X-72F80L AA is housed in a 144-pin Green LQFP package (19.7 mil pitch) with exposed thermal pad. Pin assignments are defined per Infineon's datasheet V2.1 (2011-07), Section 2.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.15 | General-purpose port 0 | Configurable as digital I/O or alternate functions including CAN TX/RX, UART, and timer capture inputs. |
| P1.0–P1.15 | General-purpose port 1 | Supports analog input (ADC0/1), PWM output (CCU6), and external interrupt sources for fast event handling. |
| P2.0–P2.15 | General-purpose port 2 | Provides external bus interface signals (A0–A15, D0–D15) when configured for multiplexed/demultiplexed memory expansion. |
| VDD, VSS | Power supply pins | Dual 3.3 V domains: core (VDD) and I/O (VDDIO); separate ground planes ensure noise immunity for analog peripherals. |
| OSCIN/OSCOUT | Crystal oscillator interface | Accepts 4–20 MHz external crystal; internal PLL generates stable 80 MHz system clock with jitter <±50 ppm. |
| BOOT0/BOOT1 | Boot mode selection | Configures startup source: internal Flash, external memory, or on-chip ROM bootloader - critical for field firmware recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Memory Protection Unit (MPU) | Enables secure partitioning of code/data regions to prevent accidental overwrites during multitasking or ISR execution. |
| Hardware CRC Checker | Programmable polynomial engine verifies Flash/SRAM integrity at boot and runtime - essential for ASIL-B compliance. |
| Peripheral Event Controller (PEC) | Eight-channel DMA-like transfer with 24-bit addressing - offloads CPU from ADC-to-memory or CAN-buffer moves. |
| MultiCAN Gateway | Message filtering, prioritization, and cross-node forwarding between two CAN buses - reduces gateway ECU BOM cost. |
| Real-Time Clock (RTC) | Independent 32.768 kHz oscillator domain with calendar support - enables time-stamped logging without CPU intervention. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive Inverter |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC275T-64F200N DC | TriCore™ architecture, 200 MHz CPU, 4 MB Flash, no legacy C166 compatibility. | Targets next-gen ASIL-D systems; requires full toolchain and firmware re-architecture. | Select only for new designs needing higher performance and ISO 26262 certification path - not drop-in replaceable. |
| SPC560P50L5CEFAY | Power Architecture, 64 MHz, 1 MB Flash, integrated e200z0 core, no CCU6x PWM hardware. | Limited PWM flexibility; lacks synchronized dual ADCs and PEC - unsuitable for high-frequency motor control. | Consider only for cost-sensitive body electronics where CAN+LIN suffices and real-time PWM precision is non-critical. |
Compared with SAK-XC2785X-72F80L AA, the TC275 offers higher compute throughput but abandons C166 binary compatibility, while the SPC560P50 lacks the deterministic PWM and ADC synchronization needed for motor control - making the XC2785X optimal for legacy-compliant, safety-aware powertrain upgrades.

FAQ
What is the maximum operating temperature range for SAK-XC2785X-72F80L AA?
The SAK-XC2785X-72F80L AA is qualified for operation from –40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements for under-hood automotive applications. Thermal derating begins above 105 °C case temperature, and junction temperature must remain below 150 °C per datasheet Section 4.1.2.
Does this microcontroller support JTAG debugging in production environments?
Yes - SAK-XC2785X-72F80L AA includes full on-chip debug support via JTAG interface compliant with IEEE 1149.1, enabling boundary-scan testing, real-time trace, and non-intrusive breakpoint insertion. The Device Access Port (DAP) also allows post-deployment firmware updates without physical rework.
Can the internal Flash be reprogrammed in-system without external hardware?
Yes - the device integrates a ROM-resident bootloader accessible via UART, CAN, or USB (when used with external PHY). Field firmware updates can be performed using Infineon's DAVE™ Bootloader tools, supporting encrypted image verification and sector-wise erase/write with ECC regeneration.
How many CAN message objects are supported simultaneously?
The MultiCAN module supports up to 64 message objects distributed across two independent CAN nodes. Each node has configurable acceptance filters, transmit/receive FIFOs, and hardware timestamping - enabling concurrent handling of diagnostic, control, and gateway traffic without CPU polling.
