Silicon Labs Expands MCU Platform with new 8-bit MCU family
New BB5 family provides more development choices for simple applications.
These new MCUs join the PG2x family of 32-bit MCUs in sharing a single development platform,
"In today's world, with an ever-expanding list of IoT devices, MCUs play a critical role in embedded computing," said
Cost-Optimized BB5 8-bit MCUs Reduce Complexity in Embedded Devices
As the applications for embedded computing continue to expand, developers need to be able to select the right hardware for the job. While 32-bit MCUs are ideal for more complex and compute-intensive tasks like machine learning inference or word recognition, there are much simpler tasks that don't require the added power, and cost, of a 32-bit MCU. What has been challenging for developers, however, is that most 8-bit and 32-bit MCUs use different development tools, making it difficult to develop for both, so developers will often absorb the extra development costs despite not needing the greater compute.
The new BB5 family includes the most powerful 8-bit MCUs on the market, as the 50 MHz core frequency in the BB5 family generates 36% more compute power than any other general 8-bit MCU. Ideal for battery-powered applications like power tools, handheld kitchen tools like immersion blenders, and even children's toys, the BB5 family supports a wide range of voltage options, from 1.7 to 5.5 volts, allowing them to last for years in the field on a coin-cell battery. They also come in a variety of packing sizes, from 2 mm x 2 mm for the BB50 MCU, while the BB51 and BB52 MCUs are 3 mm x 3 mm offering additional GPIOs and increased analog functionality. For certain applications, the 8-bit BB52 even offers greater price-performance than competitive 32-bit MCUs.
