Infineon Technologies SAK-TC1762-128F80HLAC

Overview

SAK-TC1762-128F80HLAC 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 operates at up to 80 MHz across -40°C to +125°C, integrates a single-precision FPU, 16-channel ADC (12-bit), and 2-channel FADC (10-bit, 262.5 ns min conversion). It targets automotive powertrain control units requiring deterministic real-time execution and ASIL-B capable peripheral arbitration.

For engineers reviewing the SAK-TC1762-128F80HLAC datasheet, SAK-TC1762-128F80HLAC pinout, SAK-TC1762-128F80HLAC application, or SAK-TC1762-128F80HLAC equivalent, key selection criteria include TriCore CPU cycle timing, MultiCAN message object allocation, MLI inter-processor latency, GPTA timer resolution for PWM edge placement, and Flash endurance under reprogramming cycles in engine ECU firmware updates.

Technical Context

The TC1762 implements a super-scalar TriCore v1.3 CPU with 4-stage pipeline, integrated DSP extensions, and IEEE-754-compliant single-precision FPU - enabling concurrent integer, floating-point, and bit-manipulation operations per cycle. Its memory subsystem includes 64-bit LMB to Flash, SPB for peripheral interconnect, and hardware memory protection unit supporting privilege levels and region-based access control.

Peripheral timing is tightly coupled to system clock domains: ASC/SSC/MLI interfaces derive from programmable baud rate generators synchronized to PLL output; GPTA0 uses dedicated 80 MHz clock source with sub-cycle resolution for input capture and output compare; ADC0 and FADC share analog front-end but operate on independent sampling clocks with configurable trigger sources including GPTA events and CAN message reception.

Key Specifications

Pinout & Package

SAK-TC1762-128F80HLAC is housed in a PG-LQFP-176-2 package (176-pin Low-Profile Quad Flat Package, 24 mm × 24 mm body, 0.5 mm lead pitch) with exposed thermal pad for enhanced heat transfer in engine bay environments. Pin functions are defined across four I/O banks (Port 0–3), two CAN transceiver interfaces (CAN0H/L, CAN1H/L), and dedicated debug trace pins (TDO, TDI, TMS, TCK, TRST).

FAQ

What is the maximum operating frequency and temperature range for SAK-TC1762-128F80HLAC?

The SAK-TC1762-128F80HLAC operates at up to 80 MHz across the full automotive temperature range of -40°C to +125°C. This rating is validated per Infineon's Preliminary Data Sheet V1.0 (2008-04), Section 4.1.4, and applies to all core logic, Flash, and peripheral modules when supplied with VDDCORE = 1.5 V ±3% and VDDIO = 3.3 V ±5%.

Does SAK-TC1762-128F80HLAC support ISO 26262 functional safety certification?

Yes - the TC1762 implements hardware features required for ASIL-B compliance, including lockstep-capable peripherals, memory ECC, memory protection unit, and OCDS Level 2 debug trace. While the device itself is not pre-certified, Infineon provides FMEDA reports and safety manuals enabling integration into ASIL-B systems per ISO 26262-5:2018.

How many CAN nodes and message objects does the MultiCAN module support?

The MultiCAN module in SAK-TC1762-128F80HLAC supports two independent CAN nodes (CAN0 and CAN1), with 64 free-assignable message objects shared between them. Each object supports full CAN 2.0B frame handling, hardware acceptance filtering, and FIFO buffering - confirmed in Section 3.10 of the 2008 datasheet.

What debug interface and trace capabilities are available on this microcontroller?

SAK-TC1762-128F80HLAC supports On-Chip Debug Support (OCDS) Level 2 via IEEE 1149.1 JTAG (TCK/TMS/TDI/TDO/TRST) and dedicated trace pins (TDO, TDI, TMS, TCK, TRST, plus 16-bit trace data bus). It enables real-time instruction trace, data watchpoints, and non-intrusive breakpoint insertion - detailed in Section 3.20 and Figure 3-22 of the datasheet.
