ST has introduced hardware cryptographic accelerators and associated software libraries for general-purpose and secure MCUs. The need for standardizing Post-Quantum Cryptography (PQC) involves using new techniques based on mathematical problems that are hard for quantum computers to solve. ST's offerings include the Keccak algorithm, a hash algorithm invented by ST, and are available through the X-CUBE-PQC software library for STM32 developers and the SHA-3 hardware accelerator in Stellar automotive microcontrollers. New software libraries and hardware IPs are also provided for secure microcontrollers, targeting Common Criteria and FIPS 140-3, and PQC algorithms like ML-KEM, ML-DSA, and XMSS/LMS.

➀ An inauguration ceremony has been held for a $3.2 billion SiC fab in Chongqing, China, a joint venture between Sanan Optoelectronics and STMicroelectronics.

➀ STMicroelectronics has introduced a 1A buck converter, the DCP3601, for low-voltage loads in smart meters, home appliances, and industrial converters;

➁ The converter boasts over 90% efficiency and requires only six components to complete the circuit;

➂ It offers a 3.3V-to-36V input voltage range and 1A output capability, suitable for various applications including smart meters and domestic appliances.

➀ The Italian government is reportedly using the current downturn in the chip market to replace ST's French CEO, Jean-Marc Chéry, according to Les Echos.

➁ Despite both governments holding a 27.5% stake in ST, the Italian government believes the CEO should be Italian.

➂ This follows a history of Italian CEOs at ST, with the current French CEO, Chéry, being appointed after a months-long stalemate.

STMicroelectronics and HighTec EDV-Systeme have combined HighTec’s Rust compiler with ST’s Stellar 28nm MCUs to provide safety-critical systems in software-defined vehicles. Rust ensures the resilience of critical automotive systems with its memory safety, thread safety, and data type safety provisions, while maintaining runtime efficiency comparable to C/C++. HighTec’s compiler suite allows for the integration of Rust’s safety features with legacy C/C++ code for automotive applications. The Stellar MCUs are built on Arm Cortex R52+ cores and comply with ISO 21434 cybersecurity standards and UN155 requirements.

➀ STMicroelectronics is considering a 6% workforce reduction through early retirements and attrition;

➁ The cuts could affect up to 2000 to 3000 people out of a workforce of 50,000;

➂ The company is aiming to reduce its cost base and planning an early retirement programme, mainly affecting sites in Italy and France.

➀ ST forecasted a 28% year-on-year decrease in Q1 revenues, with expectations of pausing production at some fabs and assembly plants.

➁ The CEO, Jean-Marc Chery, referred to Q1 as the low point of 2025, with no full-year forecast provided.

➂ The company cited weak automotive and industrial demand as reasons for the downturn.

➀ STMicroelectronics reported a significant decline in MCU sales in 2024 due to non-cancellable and non-rearrangeable sales contracts used in 2022 and 2023, leading to increased customer inventory and subsequent drop in 2024 sales.

➁ The company's MCU sales for the first nine months of 2024 were approximately $2.58 billion, down 41.3% from $4.4 billion in the same period of 2023.

➂ CEO Jean-Marc Chery emphasized that 2025 will be a transitional year for the company to move towards better times in 2026 and 2027, with inventory adjustments expected to last at least until the first half of 2025.
