I. SAK-TC332LP-32F200F AA Core Architecture and Performance Parameters

1.1 Core Architecture

The SAK-TC332LP-32F200F AA incorporates a single 32-bit TriCore™ TC1.6.2 core operating at a stable 200MHz frequency, with the option to customise and upgrade to 300MHz according to application requirements. The TriCore™ architecture innovatively integrates the core strengths of RISC high-performance processing, DSP data computation, and real-time control systems. It supports a 16-bit/32-bit mixed instruction set, with most instructions executable within a single cycle. Coupled with branch prediction and zero-overhead loop functionality, this significantly enhances real-time response efficiency. The core incorporates an integrated floating-point unit (FPU), supporting both fixed-point and floating-point operations. This enables efficient processing of complex control algorithms and signal processing tasks, providing computational power for precision control scenarios in automotive electronics.

1.2 Storage Configuration

The storage system employs a high-reliability design, featuring 2MB Flash programme memory and 248KB SRAM, both integrated with Error Correction Code (ECC) functionality. This effectively detects and corrects single-bit errors during memory read/write operations, substantially reducing data transmission and storage risks. The Flash memory supports firmware locking and over-the-air updates, while the SRAM provides high-speed storage for real-time data caching and interrupt context switching, meeting the stringent requirements of automotive electronics for storage stability and read/write speed.

1.3 Power Supply and Environmental Adaptability

The SAK-TC332LP-32F200F AA employs an innovative single-supply design supporting 3.3V or 5V wide-voltage input. This eliminates the need for complex external power management circuits, reducing system costs while achieving first-class power consumption control with typical power consumption below 1W. As an automotive-grade device, its operating temperature range spans -40°C to +150°C, fully compliant with the AEC-Q100 automotive standard. It withstands temperature fluctuations and electromagnetic interference in harsh environments such as automotive engine compartments, ensuring stable operation under extreme conditions. The package utilises a PG-TQFP-80 (80-pin thin quad flat package) with an exposed pad design optimised for thermal performance, aligning with the compact PCB layout requirements of automotive electronics.
