EFM8LB Laser Bee Microcontrollers, Silicon Labs
The Silicon Labs Laser Bee family of 8-Bit microcontrollers (MCU) offers high performance for analogue intensive applications operating at up to 72 MHz. They include a 14-bit ADC, 12-bit DAC, Temperature Sensor accurate to ±3°C and high-speed communication peripherals.
The 14-bit ADC (850 ksps) provides accurate analogue measurements with zero external components, improving system performance without adding cost or power. With the auto-scan/DMA/accumulation features added to the ADC, filtering is done without MCU intervention. The MCU core is freed up to perform other complex computation algorithm or can be kept in low-power mode.
Maintain consistent performance across variable environmental conditions with the integrated ±3°C Temperature Sensor. It can be used to adjust coefficients and maintain optimal performance through the operating temperature range.
The Laser Bee family are ideal for application requiring a precision MCU and where space is limited, such as optical modules. Available in packages as small as 3 x 3 mm.
EFM8 Bee Microcontrollers
The EFM8 8-bit microcontroller family has an unparalleled combination of features and capabilities including a high-speed pipelined 8051 core, ultra-low power, precision analogue and enhanced communication peripherals, integrated oscillators, small-footprint packages, and a crossbar architecture that enables flexible digital and analogue multiplexing to simplify PCB design and I/O signal routing. These next-generation 8-bit devices are aimed at the engineer developing products for the Internet-of-Things (IoT) which will be very small, perform complex processing and run off tiny batteries.
