Silicon Labs (Core Technology Co., Ltd.) announced the introduction of the new microcontroller (MCU) series of products in the 8-bonded superalog performance and peripheral integration. The new EFM8LB1 Laser Bee MCU is the latest member in the Silicon Labsefm8 MCU product combination, which integrates high-speed analog-to-digital converters (ADCs), multi-mold converters (DACs), high-precision temperature sensors, two comparators and a support up to 64KB Flash 72MHz8051 kernel. Laser Bee MCU integrates powerful simulation performance in 3mm × 3mm QFN packages, which is ideal for space-limited, performance-intensive applications, such as optical modules, tests, and measuring instruments, industrial control equipment and intelligent sensors.
The EFM8LB1 Laser Bee MCU series is ideal for high speed, analog intensive optical transceiver modules, which are widely used in telecommunications and data communication. Optical module applications require exceptional simulation and small size MCUs with high integration. The EFM8LB1 series of high-intensity simulation features exempt from the desired microfield analog components, which reduces the overall system list (BOM) cost and printed circuit board (PCB) area, and enhances system performance. For example, the Laser Bee MCU integrates up to 4 12-bit DAC, which eliminates the four-piece DAC devices that are typically required for optical modules.
14 bits of Laser Bee MCU, 900KSPS ADC includes entering sequencer and direct memory access (DMA) controllers, without MCU participation, completing raw data collection. This feature can release the MCU to perform other tasks, enhance the overall system performance, while making the MCU into low power mode to achieve energy saving. In addition, with 72MHz, based on 8051-based pipeline 8-bit MCU kernel, 70% of instructions can be performed within 1-2 clock cycles, meet the processing requirements of high-speed optical modules and other computational intensive applications.
The EFM8LB1 MCU integrates four configurable logic units (CLUs) that enables the designer to enable the combined logic and / or synchronizer without using the external device. As the smallest CLU application in the industry, the logic unit supports multiple digital functions, such as replacing the system glue logic, generating special waveforms or synchronous system event triggers. Each CLU is fully programmable, which makes the Laser BEE MCU can be easily connected to other chips in the system. The logic unit will ultimately minimize the BOM cost and product listing time by reducing the number of devices required for combination logic.
Many precision simulation applications include sensors or other components that require temperature compensation. For example, the laser driver and other components in the optical module are sensitive to temperature variations. In order to maintain a constant communication data rate, the optical module must accurately measure the temperature of the module and adjust the laser power accordingly. If the MCU lacks an accurate temperature sensor, you need to calibrate the module temperature during the manufacturing process, which will have a high cost in manufacturing time and equipment input. The Laser Bee MCU solves this problem by built-in, factory calibration of ± 3 ° C, which can achieve very precise temperature measurements and do not need to be any calibration.
Daniel Cooley, vice president of Silicon Labs and General Manager of Wireless Products, said: "As an 8-bit MCU leading supplier in the optical module market, Silicon Labs is committed to meeting the customer's higher analog performance, smaller Dimensions and lower BOM requirements. Our Laser Bee MCU provides a new generation of 8-bit solutions that combine complete hardware and software development tools that support the precision simulation performance required for optical module developers. "
