Product details
Overview
SAK-TC1767-256F133HR AD from Infineon Technologies is a 32-bit TriCore V1.3.1 single-chip microcontroller featuring a 133 MHz super-scalar CPU, integrated PCP2 peripheral control processor, 2 MB program flash, 64 KB data flash (emulating 16 KB EEPROM), and dual CAN nodes. It targets automotive powertrain and chassis control systems requiring deterministic real-time response, high-integrity memory, and multi-protocol serial connectivity.
For engineers reviewing the SAK-TC1767-256F133HR AD datasheet, SAK-TC1767-256F133HR AD pinout, SAK-TC1767-256F133HR AD application, or SAK-TC1767-256F133HR AD equivalent, key selection criteria include TriCore CPU clock stability at full temperature range, MultiCAN message object allocation flexibility, FADC conversion time under 1.5 µs, and LQFP-176 package thermal performance in engine control units.
Technical Context
The TC1767 implements a tightly coupled dual-core architecture: the main TriCore CPU executes application code with hardware FPU and configurable 8 KB instruction/4 KB data caches, while the PCP2 handles time-critical peripheral tasks via dedicated 8 KB PRAM and 16 KB CMEM-both cores operate synchronously at 133 MHz across −40°C to 125°C. Its bus hierarchy includes 64-bit local memory buses for latency-critical flash/data access and a 32-bit system peripheral bus with LFI bridge for scalable peripheral integration.
Real-time determinism is enforced through a dual-level interrupt system supporting 2 × 255 hardware priority levels, 8-channel DMA with scatter-gather capability, and autonomous GPTA/LTCA2 timer arrays enabling complex I/O waveform generation without CPU intervention-critical for ignition timing and valve control in ICE applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | TriCore V1.3.1 super-scalar 32-bit with 4-stage pipeline and single-precision FPU-enables simultaneous integer/DSP/FPU operations for motor control algorithms. |
| Max Clock Frequency | 133 MHz over full industrial temperature range (−40°C to +125°C)-guarantees deterministic timing in under-hood ECU environments. |
| Flash Memory | 2 MB PFlash + 64 KB DFlash (16 KB EEPROM-equivalent)-supports A/B firmware swapping and runtime parameter storage with wear leveling. |
| Analog Inputs | 32-channel ADC with Fast ADC (FADC) sub-block-achieves ≤1.5 µs conversion time for closed-loop fuel injection sensing. |
| CAN Interfaces | Dual CAN 2.0B controllers with 64 message objects and FIFO buffering-enables concurrent powertrain and body network communication with hardware gatewaying. |
| Package | PG-LQFP-176 (24 × 24 mm, 0.5 mm pitch)-provides thermal dissipation margin for 1.5 W typical power consumption in compact ECU modules. |
| DMA Channels | 8-channel controller with scatter-gather support-offloads CPU from high-bandwidth sensor data transfers (e.g., crankshaft position + knock sensor streams). |
Pinout & Package
SAK-TC1767-256F133HR AD is housed in a PG-LQFP-176 package (24 mm × 24 mm, 0.5 mm lead pitch) with exposed thermal pad for enhanced heat dissipation in automotive under-hood applications. Pin functions are defined per Infineon's datasheet Section 3.1, including dedicated JTAG/DAP debug interfaces, dual CANH/CANL differential pairs, 32 ADC input pins mapped to VREFP/VREFN references, and 16-bit external bus interface signals.

Key Features
| Feature | Design Value |
|---|---|
| Dual-core deterministic execution | CPU + PCP2 cores share memory space but execute independent real-time tasks-reduces software complexity in safety-critical ASIL-B systems. |
| Hardware FPU acceleration | Single-precision floating-point operations executed in 1–3 cycles-accelerates PID loop calculations for electronic throttle control. |
| MultiCAN message object flexibility | 64 assignable message objects with programmable acceptance filters-supports dynamic reconfiguration of CAN ID filtering during vehicle mode transitions. |
| FADC sub-system | ≤1.5 µs conversion time with hardware trigger synchronization-captures transient knock events within 2 µs window for adaptive spark retard. |
| BootROM with flash security | 16 KB ROM containing secure boot loader and tuning protection logic-prevents unauthorized firmware modification in production ECUs. |
Applications
| Engine Control Unit (ECU) | Transmission Control Module (TCM) |
|---|---|

IC Role / Device Role / Timing Role: FADC subsystem captures 32 analog channels (wheel speed, brake pressure, pedal travel) with synchronized 1.5 µs conversion for real-time slip calculation. Use Value: 32-channel ADC with hardware trigger alignment ensures <5 µs timestamp jitter across all critical braking sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC1797-512F180HR BA | Higher clock (180 MHz), larger PFlash (4 MB), added Ethernet MAC and USB 2.0 PHY-requires additional magnetics and layout controls. | Targeted at domain controllers integrating ADAS sensor fusion-not suitable for cost-sensitive engine ECU replacements. | Select when migrating to zonal architecture with Ethernet backbone; avoid for legacy CAN-only designs due to pinout incompatibility. |
| SPC56EL70L5 | Power Architecture e200z7 core, 128 KB RAM, 2 MB Flash, dual CAN FD-but lacks TriCore DSP extensions and FADC sub-system. | Optimized for body control modules with lower real-time determinism requirements-no hardware support for sub-microsecond analog capture. | Prefer for non-powertrain applications where CAN FD bandwidth outweighs analog acquisition needs; not drop-in for TC1767-based ignition systems. |
Compared with SAK-TC1767-256F133HR AD, the TC1797 offers higher compute density for next-gen gateways but increases BOM cost and thermal design complexity, while the SPC56EL70L5 trades TriCore's deterministic analog processing for broader automotive qualification scope-making the TC1767 optimal for cost-constrained, high-precision powertrain control.

FAQ
What is the maximum operating temperature specification for SAK-TC1767-256F133HR AD?
The device is qualified for continuous operation from −40°C to +125°C ambient temperature, with internal junction temperature limits defined in datasheet Section 5.1.4. This rating is validated per AEC-Q100 Grade 1 requirements and applies to all core, peripheral, and memory functions-including 133 MHz CPU execution and 2 MB flash read/write cycles-without derating.
Does SAK-TC1767-256F133HR AD include hardware security features for firmware protection?
Yes, it integrates tuning protection logic in BootROM and supports flash memory locking via write-protection bits in the Flash Configuration Register (FCR). These mechanisms prevent unauthorized firmware updates or memory dumps, meeting ISO 26262 ASIL-B functional safety requirements for secure boot and runtime integrity verification.
Can the MultiCAN module support CAN FD frames, or is it limited to classical CAN 2.0B?
The MultiCAN module in SAK-TC1767-256F133HR AD supports only Classical CAN 2.0B (up to 1 Mbit/s) and does not implement CAN FD protocol features such as flexible data-rate or extended data length. Its 64 message objects and hardware FIFOs are optimized for deterministic handling of standard CAN identifiers in powertrain networks.
What debug interface options are supported for on-chip development and testing?
The device provides JTAG and DAP (Debug Access Port) interfaces compliant with IEEE 1149.1 and ARM CoreSight standards. Both support real-time trace via OCDS (On-Chip Debug Support), breakpoint setting, memory inspection, and live register monitoring-enabling full visibility into TriCore CPU and PCP2 execution states during ECU calibration and validation.
