STMicroelectronics has introduced a brand new course of expertise to design and construct transistors for next-generation embedded processing units. The superior expertise is predicated on 18nm totally depleted silicon on insulator (FD-SOI) course of with embedded section change reminiscence (ePCM). This has introduced down characteristic dimension to 18nm from 20nm.
Co-developed with Samsung Foundry, this expertise improves energy consumption, allows bigger reminiscence sizes and better integration of peripherals. The expertise gives vital enhancements over the presently in use 40nm eNVM (embedded non-volatile reminiscence) expertise.
The expertise supplies greater than 50% higher performance-to-power ratio which is a major discount in energy consumption. In FD-SOI expertise, the channel (supplies path for conduction in a transistor) is depleted of majority carriers (chargeable for conduction) in off state, which reduces leakage present. Because the silicon layer rests on an insulator, interference can also be decreased.
The ePCM expertise makes use of the change in section of a fabric to retailer information. This enables for extra on chip house for reminiscence and peripherals. The expertise utilized by ST supplies 2.5 instances larger non-volatile reminiscence density and 3 times larger digital density for integration of digital peripherals,
The expertise has additionally led to 3dB enchancment in noise determine which boosts RF(radio frequency) efficiency in wi-fi microcontroller models (MCUs). It additionally helps 3V operation for analog options and delivers the reliability required for demanding industrial purposes like high-temperature operation, radiation hardening, and information retention capabilities.
Remi El-Ouazzane, President of Microcontrollers, Digital ICs and RF merchandise Group at STMicroelectronics, mentioned: “ST has pioneered and dropped at our clients FD-SOI and PCM applied sciences for automotive and aerospace purposes. We are actually taking the following step to deliver the advantages of those applied sciences to builders of commercial purposes beginning with our next-generation STM32 microcontrollers.”
Microcontrollers based mostly on this expertise will present builders with high-performance, low-power, and wi-fi MCUs. They are going to assist edge AI processing, multi-protocol RF stacks, over-the-air updates, and superior safety features. The expertise can even allow using extra extremely built-in and cost-effective microcontrollers for designs presently utilizing microprocessors.
The primary microcontroller based mostly on this expertise, STM32, will combine probably the most superior ARM Cortex-M core, optimised for machine studying and digital sign processing purposes. It should have quick and versatile exterior reminiscence interfaces, superior graphic capabilities, quite a few analog and digital peripherals, and superior, licensed safety features.
STM32 can be sampled to chose clients within the second half of 2024, with manufacturing deliberate for the second half of 2025.
