STA1052S1-TR

STMicroelectronics's STA1052S1-TR redefines performance standards in Embedded - Microcontrollers - Application Specific, specifically developed for next-generation IoT edge nodes. This application-specific microcontroller combines ultra-low power consumption with robust security features, making it ideal for distributed sensor networks and smart city infrastructure.Designed for Automotive implementations, the microcontroller's hardware security modules exceed FIPS-140-2 requirements. Its tamper-resistant design includes active shield technology for physical attack prevention.The ARM7® architecture incorporates branch prediction and speculative execution for improved DSP performance. Cryptographic extensions accelerate AES-256 operations by 8x compared to software implementations.Supporting ROM (384kB) configurations, the memory controller implements error detection and correction. The dual-bank flash architecture enables secure over-the-air updates without service interruption.The 128K x 8 memory subsystem implements parity protection for all SRAM blocks. The memory controller supports both little-endian and big-endian data formats for protocol flexibility.With I²C, I²S, SPI, UART, USB connectivity options, the device supports deterministic industrial Ethernet protocols. Each interface includes integrated magnetics for simplified PoE (Power over Ethernet) implementations.The 1.71V ~ 1.89V power architecture implements adaptive body biasing for leakage current reduction. The integrated buck converter achieves 92% power efficiency across load variations.Certified for -40°C ~ 85°C operation, the device utilizes copper pillar bump technology for enhanced thermal conductivity. The package design minimizes thermal resistance to PCB substrates.The Surface Mount option supports reflow profiles compatible with lead-free SAC305 solder. Package warpage is controlled to <0.05mm for high-yield assembly processes.Available in 144-LQFP format, the package incorporates stress-relief features for improved board-level reliability. Moisture sensitivity meets JEDEC J-STD-020D Level 3 standards.Supplied in 144-LQFP (20x20) configuration, each unit includes unique cryptographic identifiers for supply chain authentication. Tape-and-reel packaging supports automated pick-and-place assembly.
