EFM8 Universal Bee

EFM8UB Universal Bee MCUs claim to be the industry's foremost 8bit USB connectivity solution, with speeds of up to 48MHz and 8KB to 64KB flash sizes. The MCUs combine a high-precision internal oscillator, clock recovery circuit and an integrated full-speed USB transceiver. Low-energy USB MCU versions can reduce USB power consumption by up to 90 per cent. An on-chip battery charger detection module reduces BOM count and system cost. The MCUs' exceptional peripheral integration and small package sizes dramatically reduce the cost and complexity of adding USB connectivity to personal medical devices, wearables, communication bridges, toys, remote controls and thermostats.

Silicon Labs fully supports the EFM8 MCU family with comprehensive software and hardware toolkits offering an optimal, developer-friendly out-of-the-box experience. Silicon Lab's enhanced Simplicity Studio development platform provides a unified 8/32bit and wireless development environment that simplifies and accelerates 8bit design with one-click access to Eclipse debuggers and plug-ins, Keil PK51 build tools, third-party tools support, a capacitive sense profiler, demos, software examples, data sheets, application notes, technical support and community forums. EFM8 customers can download Simplicity Studio at no charge at

Samples and production quantities of Silicon Labs' EFM8 MCUs are available in a variety of small-footprint QFN, QSOP, SOIC and QFP packages. Starting prices for EFM8 MCUs in 10,000-unit quantities range from $0.21 for EFM8BB MCUs to $0.32 for EFM8SB MCUs to $0.43 for EFM8UB MCUs. EFM8BB Busy Bee, EFM8SB Sleepy Bee and EFM8UB Universal Bee starter kits are priced at $29 each.
