Product details
Overview
SAL-TC290TC-96F300 BC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P super-scalar CPU cores, lockstep shadow core for ASIL-D safety compliance, 8 MB ECC-protected program flash, 768 KB data flash for EEPROM emulation, and integrated 128-channel DMA. It targets automotive powertrain and chassis control systems requiring functional safety up to ISO 26262 ASIL-D.
For engineers reviewing the SAL-TC290TC-96F300 BC datasheet, SAL-TC290TC-96F300 BC pinout, SAL-TC290TC-96F300 BC application, or SAL-TC290TC-96F300 BC equivalent, key selection criteria include dual-core lockstep timing integrity, ERAY/ETH/DSADC peripheral integration, BGA516 package thermal and routing constraints, and flash ECC coverage for safety-critical boot code.
Technical Context
The SAL-TC290TC-96F300 BC implements a deterministic real-time architecture with two independent TC1.6P cores (300 MHz max), each with dedicated 120 KB DSPR, 32 KB PSPR, ICACHE/DCACHE, and MAC units sustaining 2 operations/cycle. The lockstepped shadow core provides hardware-level fault detection for safety-critical execution paths.
It integrates safety-critical peripherals including ERAY (flexible time-triggered CAN FD extension), Ethernet MAC (10/100 Mbit/s), DSADC (16-bit, 1.5 MSps), VADC (12-bit, 1.25 MSps), and EVR voltage regulators with monitoring. All on-chip memories feature full ECC protection, and reset behavior includes configurable pull-up/pull-down on all I/O pins per datasheet section 2.1.3.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon SAL-TC297TC-96F300 BC | Same dual-core TC1.6P architecture but with BGA416 package (fewer I/O: 336 vs 424), reduced PFLASH (4 MB), and no Ethernet MAC. | Suitable for cost-sensitive chassis modules where Ethernet connectivity and maximum I/O density are not required. | Select when footprint, thermal budget, or BOM cost constrain use of BGA516 and 10/100 Ethernet is unnecessary. |
| NXP S32K344W1MTAT0ML | ARM Cortex-R52 dual-core (320 MHz), 8 MB flash, ASIL-D support, but lacks ERAY and integrated DSADC; uses external SERDES for high-speed interfaces. | Targets gateway and body control where AUTOSAR Adaptive compatibility and PCIe/SATA are prioritized over time-triggered fieldbus determinism. | Prefer when ARM ecosystem tooling, AUTOSAR Adaptive stack, or PCIe expansion is required - not for ERAY-dependent safety-critical actuation. |
Compared with SAL-TC297TC-96F300 BC, this part adds Ethernet and higher I/O count in BGA516, enabling centralized domain control; versus S32K344, it delivers native ERAY timing guarantees and integrated DSADC, eliminating external signal conditioning for motor control.

FAQ
What is the maximum operating temperature range for SAL-TC290TC-96F300 BC?
The SAL-TC290TC-96F300 BC is qualified for operation from −40 °C to +125 °C ambient temperature, as specified in section 3.4 of the BC-step datasheet (V1.1, March 2019). This rating applies to the full 300 MHz CPU frequency range and includes derating allowances for junction temperature under sustained load conditions in automotive under-hood environments.
Does SAL-TC290TC-96F300 BC support JTAG debugging in production mode?
Yes - the device supports full JTAG debug via TDI/TDO/TCK/TMS/ TRST pins (pins A1–A5 per BGA516 pinout), with boundary scan and real-time trace capabilities. Debug access remains enabled in production mode but can be disabled via fuse programming to prevent unauthorized access, as detailed in section 3.20 of the datasheet.
How is flash memory protected against corruption during power loss?
All 8 MB PFLASH and 768 KB DFLASH include hardware ECC (SEC-DED), write-protection registers, and atomic sector erase/write operations. Flash update routines must use the built-in Safe Flash Driver (SFD) with checksum validation and rollback capability - documented in Infineon's AURIX™ Flash Programming Manual v1.4.
Can SAL-TC290TC-96F300 BC operate with a single 5 V supply?
No - the device requires three distinct supply domains: 1.3 V (core), 3.3 V (I/O), and 5 V (EBU/external interface). While 5 V is used for certain peripheral buffers, the internal regulators (EVR) generate 1.3 V and 3.3 V from an external 5 V input; direct 5 V core operation is not supported and would exceed absolute maximum ratings.
