Overview
SAK-TC222S-12F133N AC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E CPU core, 133 MHz max clock, 1 MB program flash, 96 KB data flash (EEPROM-emulated), and integrated MultiCAN+ (3 nodes, CAN FD support). It delivers ASIL-D functional safety compliance for automotive powertrain and chassis control systems.
For engineers reviewing the SAK-TC222S-12F133N AC datasheet, SAK-TC222S-12F133N AC pinout, SAK-TC222S-12F133N AC application, or SAK-TC222S-12F133N AC equivalent, this part supports deterministic real-time execution, hardware ECC on all memories, dual-core lockstep monitoring, and integrated GTM for autonomous I/O timing-critical for ISO 26262-compliant ECU development.
Technical Context
The SAK-TC222S-12F133N AC implements a safety-critical architecture centered on a primary TC1.6E scalar core paired with a lockstepped shadow checker core, both operating at up to 133 MHz across −40°C to 125°C. Its Clock Generation Unit includes a system PLL and backup clock source, enabling fail-safe clock domain management.
On-chip peripherals include a MultiCAN+ module with three independent CAN FD controllers (128 message objects), four QSPI channels (50 Mbit/s master/slave), two ASCLIN interfaces with LIN v2.1 support, and a GTM with TIM/TOM/DTM subsystems for sensor signal conditioning and PWM generation without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | TriCore TC1.6E + lockstepped checker core; enables ASIL-D fault detection via instruction-level comparison. |
| Max Clock Frequency | 133 MHz over full industrial temperature range (−40°C to +125°C); ensures deterministic timing in safety-critical loops. |
| Flash Memory | 1 MB PFLASH + 96 KB DFLASH; DFLASH supports EEPROM emulation with wear leveling and ECC protection. |

FAQ
Does SAK-TC222S-12F133N AC support CAN FD?
Yes, it integrates a MultiCAN+ module with three fully independent CAN FD controllers supporting bit rates up to 5 Mbps, 64-byte payloads, and flexible message object allocation. All CAN FD features-including ISO 11898-1:2015 compliance and protocol arbitration-are implemented in hardware without CPU overhead.
What debug interfaces does this MCU provide?
It supports IEEE 1149.1-compliant 5-wire JTAG and ARM CoreSight-compatible DAP (Device Access Port) for OCDS Level 1 debugging. Both interfaces enable real-time trace, breakpoint setting, memory inspection, and safety monitor register access during development and field diagnostics.
Is external RAM required for operation?
No. The device contains 88 KB of on-chip DSPR (data scratchpad RAM), 8 KB PSPR (program scratchpad RAM), and 8 KB instruction cache-all ECC-protected and sufficient for typical ASIL-D ECU firmware. External RAM is optional and only used for non-safety-critical data logging or OTA update staging.
How is functional safety achieved without external monitors?
Functional safety is implemented via integrated hardware: lockstep CPU cores with real-time comparison, SMU for alarm aggregation, MTU for memory self-test, IOM for I/O pin health checks, and ECC on all memories. These elements collectively satisfy ASIL-D requirements per ISO 26262 Part 5 without external safety chips.
