STM32C0: Cost Reduction, Breaking 32-bit Barriers

Amidst the dynamic landscape of diverse innovations, 8-bit microcontrollers have maintained a stable market presence owing to their competitive pricing and robust application ecosystem. However, the evolving demands for future upgrades, encompassing aspects such as storage, computing throughput, and pin count, may pose constraints on 8-bit microcontrollers. Achieving a harmonious balance between innovation and cost is imperative for future advancements, particularly in the pursuit of a streamlined Bill of Materials (BoM).

The STM32C0 series of microcontrollers has successfully surpassed the cost impediments associated with 32-bit microcontrollers. Not only do they rival 8-bit microcontrollers in terms of pricing and packaging, but they also elevate the standard by augmenting storage capacity. Anticipated to be launched in 2024, the latest models are projected to provide a remarkable 256 KB flash memory and 32 KB RAM, outclassing traditional 8-bit microcontroller configurations. Notably, the STM32C0 series introduces a crystal-less USB controller, facilitating efficient USB power transmission. This innovation reduces the BoM by configuring internal clocks and simplifies PCB layout.

With the diminishing entry barriers for 32-bit microcontroller usage and the continuous evolution of applications, a transformative shift towards 32-bit microcontrollers is on the horizon. The STM32C0 series not only offers a diverse range of 32-bit microcontroller packaging options but also provides a cost-effective and seamless transition for designers migrating from 8-bit to advanced 32-bit architecture. This transition maintains compatibility for future advancements towards other STM32 advanced series products.

STMicroelectronics presents the STM32C011x4/x6 microcontrollers, built on the high-performance Arm Cortex-M0+ 32-bit RISC core, operating at frequencies of up to 48 MHz. These microcontrollers find applicability across a broad spectrum of sectors, including consumer electronics, industrial applications, IoT, and home appliances.

Beyond microcontrollers, the market is witnessing the emergence of cutting-edge technological products. STMicroelectronics introduces the VL53L4CD, a Time-of-Flight (ToF) proximity sensor designed for precision in proximity and short-distance measurements. Offering a remarkable range from 1 mm to 1300 mm, it features an 18° Field of View (FoV) and excels in ambient light conditions.

Furthermore, Boréas Technologies introduces the BOS1921 piezoelectric driver, capable of driving actuators with waveforms reaching up to 190 Vpk-pk. Operating on a power supply voltage of 3 to 5.5 V, its low power consumption and compact design make it an ideal choice for applications requiring minimal power usage.
