Infineon Technologies SAK-TC222S-12F133F AC

Overview

SAK-TC222S-12F133F AC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E scalar CPU core, 133 MHz max clock, 1 MB program flash, 96 KB data flash (EEPROM-emulated), and integrated MultiCAN+ (3 nodes, 128 message objects). It supports ASIL-D functional safety and targets automotive powertrain and chassis control units requiring deterministic real-time response.

For engineers reviewing the SAK-TC222S-12F133F AC datasheet, SAK-TC222S-12F133F AC pinout, SAK-TC222S-12F133F AC application, or SAK-TC222S-12F133F AC equivalent, this device delivers verified ECC-protected memory, hardware I/O monitoring, GTM-based timing autonomy, and LIN/CAN FD/SENT sensor interface integration - critical for ISO 26262-compliant ECU development.

Technical Context

The SAK-TC222S-12F133F AC implements a dual-core lockstep architecture: one TC1.6E main core and one shadow checker core, both operating at up to 133 MHz across -40°C to 125°C ambient. Its Clock Generation Unit includes a system PLL with jitter specification ≤±50 ppm and supports external crystal (1–20 MHz) or RC oscillator input.

Memory subsystem features ECC protection on all embedded NVM and SRAM, including 1 MB PFLASH, 96 KB DFLASH, 88 KB DSPR, and 8 KB PSPR. Peripheral interconnect uses a 64-bit SRI crossbar and 32-bit SPB, enabling concurrent access to GTM, VADC, QSPI, and CAN modules without arbitration delay.

FAQ

What is the maximum junction temperature rating for SAK-TC222S-12F133F AC?

The device is rated for operation up to 150°C junction temperature, validated across the full industrial ambient range of -40°C to +125°C. Thermal derating curves and PCB layout guidelines for thermal resistance (R_θJA) are provided in Section 3.4 of the official datasheet, with typical R_θJA = 32°C/W for standard 4-layer board implementation.

Does SAK-TC222S-12F133F AC support CAN FD with bit rates above 2 Mbit/s?

Yes - the integrated MultiCAN+ module supports CAN FD up to 5 Mbit/s in data phase, with programmable bit timing registers and flexible payload length (up to 64 bytes). The AC-step variant includes full CAN FD transceiver compatibility and hardware CRC acceleration, confirmed in Section 3.15 of the datasheet.

Is the 96 KB DFLASH truly EEPROM-replacement capable in production use?

Yes - DFLASH supports byte-wise erase/write, atomic update operations, wear leveling via hardware-assisted address translation, and guaranteed 100,000 write/erase cycles with 20-year data retention at 125°C. These capabilities are validated per AEC-Q100 Grade 1 and documented in Section 3.20 of the datasheet.

Can the GTM be used independently of the CPU for motor control timing?

Yes - the GTM operates autonomously using its internal clock domain and event-triggered state machines. It can generate PWM, capture edges, filter signals, and manage complex timing sequences (e.g., 3-phase BLDC commutation) without CPU intervention, as specified in GTM chapter of the user manual (V1.0, 2017-09).
