Product details
Overview
SAF-TC1164-128F80HL AB from Infineon Technologies is a 32-bit TriCore v1.3 single-chip microcontroller with 80 MHz CPU clock, 1024 KB program flash, 40 KB SRAM, and integrated MultiCAN (2 nodes), ASC/SSC serial interfaces, and dual ADC subsystems (16-channel 12-bit ADC + 2-channel 10-bit FADC). It targets automotive powertrain and chassis control units requiring deterministic real-time response, CAN-based sensor/actuator networking, and mixed-signal processing.
For engineers reviewing the SAF-TC1164-128F80HL AB datasheet, SAF-TC1164-128F80HL AB pinout, SAF-TC1164-128F80HL AB application, or SAF-TC1164-128F80HL AB equivalent, key selection criteria include its TriCore CPU performance at full industrial temperature range (−40°C to +85°C), on-chip PCP2 co-processor for autonomous peripheral handling, 176-pin LQFP package with 81 GPIOs, and hardware-supported CAN message object management.
Technical Context
The TC1164 implements a dual-bus architecture: a 64-bit Local Memory Bus (LMB) connects CPU and flash memory for low-latency instruction fetch, while the System Peripheral Bus (SPB) interconnects peripherals including MultiCAN, ASC, SSC, MLI, and GPTA. Its TriCore v1.3 core integrates DSP extensions and a single-precision FPU, enabling concurrent control-law computation and signal processing.
Peripheral Control Processor (PCP2) operates independently with dedicated 8 KB PRAM and 12 KB CMEM, executing time-critical I/O tasks such as CAN message filtering, ADC sequence control, and timer-triggered DMA transfers-offloading the main CPU without software intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | TriCore v1.3 32-bit super-scalar with 4-stage pipeline, 80 MHz max frequency across −40°C to +85°C - enables hard real-time task scheduling in safety-critical automotive ECUs. |
| Flash Memory | 1024 KB program flash + 16 KB data flash (EEPROM emulation) - supports A/B firmware swapping and non-volatile parameter storage without external EEPROM. |
| RAM | 40 KB local SRAM + 8 KB overlay RAM + 8 KB SPRAM + 8 KB instruction cache - provides deterministic latency for control loops and interrupt service routines. |
| ADC System | 16-channel 12-bit ADC (32 input lines) + 2-channel 10-bit FADC (262.5 ns min conversion) - enables simultaneous high-resolution sensor sampling and fast transient detection (e.g., knock sensing). |
| CAN Interface | MultiCAN module with 2 independent CAN nodes and 64 configurable message objects - supports gateway functionality and prioritized FIFO-based message buffering for ASAM-compliant diagnostics. |
| Package | PG-LQFP-176-2 (24 × 24 mm, 0.5 mm pitch) - compatible with standard SMT reflow profiles and supports thermal dissipation up to 1.5 W under industrial ambient conditions. |
| Supply Voltages | Core: 1.5 V ±3%; I/O: 3.3 V ±10% - decoupling requirements defined per section 4.2.6; enables integration with common automotive 3.3 V supply rails. |
Pinout & Package
SAF-TC1164-128F80HL AB is housed in a PG-LQFP-176-2 package: 176-pin quad flat pack with exposed thermal pad, 24 mm × 24 mm body, 0.5 mm lead pitch, and RoHS-compliant matte tin plating. Thermal resistance θJA = 29.5 K/W (JEDEC Std. 51-7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP0–VDDP7 | Digital I/O power supply (3.3 V) | Eight independent 3.3 V supply pins distributed across package edges - reduce simultaneous switching noise and support localized decoupling for GPIO banks. |
| VSSP0–VSSP7 | Digital I/O ground return | Paired with VDDP pins to form low-inductance return paths - critical for EMI compliance in automotive CAN/ASC communication. |
| VDDC | Core logic supply (1.5 V) | Single 1.5 V input for CPU, cache, and internal buses - requires tight regulation (±3%) and low-noise filtering per section 4.2.6. |
| VSSC | Core ground reference | Isolated ground plane connection for core logic - separates analog/digital return currents to minimize jitter in PLL and ADC operation. |
| OSCIN / OSCOUT | Crystal oscillator input/output | Supports 1–20 MHz fundamental-mode quartz crystals - drives internal PLL to generate 80 MHz system clock with jitter < 100 ps RMS (section 4.3.5). |
| TxD0 / RxD0 | ASC0 transmit/receive data | Asynchronous serial interface with programmable baud rate up to 2 Mbps - used for bootloader communication and diagnostic services (UDS via ISO 14229). |
| CANH0 / CANL0 | CAN node 0 differential bus lines | Integrated CAN transceiver drivers compliant with ISO 11898-2 - enable direct connection to automotive CAN physical layer without external transceiver. |
Key Features
| Feature | Design Value |
|---|---|
| TriCore CPU with FPU | Single-precision floating-point unit accelerates motor control algorithms (e.g., field-oriented control) without software emulation overhead. |
| PCP2 Co-processor | Autonomous execution of peripheral sequences (e.g., ADC scan + CAN transmission) frees CPU for higher-layer application logic. |
| MultiCAN with 64 message objects | Hardware-managed FIFO and priority arbitration eliminate CPU polling - reduces interrupt load by >70% in multi-node gateway applications. |
| FADC with comb filters | On-the-fly digital filtering (decimation + averaging) reduces raw sensor data volume before CPU transfer - cuts DMA bandwidth usage by 4× vs. raw ADC output. |
| OCDS Level 2 debug support | Real-time trace of CPU, PCP2, and DMA activity via JTAG - enables cycle-accurate validation of timing-critical control loops per ISO 26262 ASIL-B. |

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 |
|---|---|---|---|
| TC1766 | TriCore v1.6 core, 133 MHz max, 2 MB flash, no FADC - adds Ethernet MAC and enhanced safety features (lockstep cores). | Targets ASIL-D brake/steer systems requiring dual-core lockstep; lacks FADC optimized for fast analog transients. | Select TC1766 when functional safety certification (ISO 26262) and network connectivity outweigh need for ultra-fast analog acquisition. |
| TC275 | TriCore v1.6 + ARM Cortex-M core, 200 MHz, 4 MB flash, integrated Ethernet AVB - replaces FADC with higher-resolution SAR ADC (12-bit @ 1 MSPS). | Suitable for domain controllers integrating ADAS sensor fusion; FADC replacement requires software-based filtering for transient events. | Choose TC275 for next-gen zonal architectures needing multi-protocol support and scalable compute, accepting trade-off in analog acquisition speed. |
Compared with TC1164, TC1766 offers higher clock speed and safety mechanisms but removes the hardware-accelerated FADC; TC275 provides broader connectivity and larger memory but shifts analog processing burden to software - making TC1164 optimal for cost-sensitive, analog-intensive powertrain ECUs where sub-microsecond transient capture is essential.

FAQ
What is the maximum operating frequency of the SAF-TC1164-128F80HL AB under industrial temperature conditions?
The SAF-TC1164-128F80HL AB operates at a guaranteed maximum frequency of 80 MHz across the full industrial temperature range of −40°C to +85°C, as specified in Section 4.1.4 (Operating Conditions) and validated in AC parameter testing (Section 4.3.5). This frequency is sustained without derating when core voltage (VDDC) is maintained at 1.5 V ±3% and all thermal limits are observed.
Does the SAF-TC1164-128F80HL AB include an integrated CAN transceiver?
No, the SAF-TC1164-128F80HL AB integrates a MultiCAN controller with two fully featured CAN protocol engines and 64 configurable message objects, but it does not include physical-layer transceivers. External ISO 11898-2-compliant transceivers (e.g., Infineon TLE6250) must be used on CANH/CANL pins to interface with the automotive CAN bus.
How is the Flash memory organized for firmware updates and data logging?
The device contains 1024 KB of program flash (for executable code and constants) and 16 KB of data flash configured for EEPROM emulation. The data flash supports byte-wise erase and write operations with 100,000-cycle endurance, enabling robust parameter storage and over-the-air update staging without requiring external non-volatile memory.
What debug capabilities does the SAF-TC1164-128F80HL AB provide for real-time system validation?
The SAF-TC1164-128F80HL AB supports OCDS Level 2 debug, enabling real-time tracing of CPU instructions, PCP2 execution flow, and DMA transfers via JTAG. Trace data is buffered in on-chip memory and accessible through Infineon's DAS-TRICORE tools, supporting cycle-accurate analysis of timing-critical control loops required for ISO 26262 development.
