Product details
Overview
SAK-TC1762-128F66HL AC from Infineon Technologies is a 32-bit TriCore v1.3 single-chip microcontroller with 1024 KB on-chip Flash, 32 KB SRAM, and dual CAN nodes. It integrates a 66 MHz CPU core, 16-channel ADC (12-bit configurable), and MultiCAN controller for automotive real-time control. Used in engine control units (ECUs) requiring deterministic timing, safety-critical I/O handling, and CAN-based vehicle network communication.
For engineers reviewing the SAK-TC1762-128F66HL AC datasheet, SAK-TC1762-128F66HL AC pinout, SAK-TC1762-128F66HL AC application, or SAK-TC1762-128F66HL AC equivalent, this page delivers verified technical context, validated pin functions, automotive-grade thermal and electrical specs, and direct alternative part comparisons - all grounded in the official Infineon V1.0 Preliminary Data Sheet (Apr. 2008).
Technical Context
The TC1762 implements a super-scalar TriCore v1.3 architecture with 4-stage pipeline, single-precision FPU, and hardware DSP extensions enabling concurrent instruction execution and bit-manipulation acceleration. Its memory subsystem includes 1024 KB Flash with ECC, 32 KB local SRAM, and 8 KB SPRAM for time-critical data buffering.
Peripheral integration centers on real-time determinism: the MultiCAN module supports two independent CAN 2.0B controllers with 64 message objects and FIFO-based gatewaying; the GPTA0 timer array provides autonomous input capture, PWM generation, and digital filtering without CPU intervention; the FADC achieves 10-bit conversion in ≤318.2 ns at 66 MHz.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC1766-128F80HL AC | 80 MHz max frequency, 128 KB RAM (vs. 32 KB), same package and peripheral set - higher compute headroom but increased power draw. | Preferred for next-gen ECUs requiring >66 MHz deterministic throughput, e.g., predictive combustion modeling or AI-based anomaly detection. | Select when sustained CPU load exceeds 70% at 66 MHz; verify thermal margin due to higher core current (2.1 A vs. 1.7 A). |
| SPC560P50L5 | Power Architecture e200z0 core, 64 MHz, 512 KB Flash, 48 KB RAM, single CAN - lacks MultiCAN, GPTA, and FADC acceleration. | Suitable for cost-sensitive body control modules where dual CAN and high-speed ADC are not required. | Choose only for non-powertrain applications; cannot substitute directly in ECU/TCM designs due to missing FADC and GPTA hardware features. |
Compared with SAK-TC1762-128F66HL AC, the TC1766 offers higher clock rate and RAM for compute-intensive upgrades, while the SPC560P50L5 trades peripheral richness for lower cost and simpler toolchain - neither matches the TC1762's balance of CAN flexibility, analog acquisition speed, and real-time timer autonomy in powertrain control.

FAQ
What is the maximum operating temperature for SAK-TC1762-128F66HL AC?
The device is qualified for continuous operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating applies to the full functional specification including 66 MHz CPU operation, MultiCAN, and ADC performance - validated per Infineon's preliminary datasheet Section 4.1.4.
Does SAK-TC1762-128F66HL AC support CAN FD?
No. The MultiCAN module implements CAN 2.0B only, with bit rates up to 1 Mbps and 64 message objects. CAN FD functionality is not present in the TC1762 silicon - later TriCore generations (e.g., TC2xx) introduced CAN FD support, but this part remains strictly CAN 2.0B compliant.
Is external RAM required for typical ECU applications?
No. The on-chip memory configuration - 32 KB SRAM, 8 KB SPRAM, 8 KB instruction cache, and 1024 KB Flash - is sufficient for full ECU firmware execution, including RTOS, control algorithms, and diagnostic stacks. External RAM is unnecessary unless custom high-bandwidth data logging is implemented.
What debug interface does SAK-TC1762-128F66HL AC use?
It supports On-Chip Debug Support (OCDS) Level 1 and 2 via JTAG, with full CPU and DMA trace capability. For production calibration and multi-core tracing, Infineon's dedicated TC1766ED emulation device connects via USB 1.1 - the MCU itself does not integrate USB PHY.
