EFM8 Laser Bee Family
EFM8LB1 Data Sheet
The EFM8LB1, part of the Laser Bee family of MCUs, is a per-
formance line of 8-bit microcontrollers with a comprehensive ana-
log and digital feature set in small packages.
These devices offer state-of-the-art performance by integrating 14-bit ADC, internal
calibrated temperature sensor (±3 °C), and up to four 12-bit DACs into small packages,
making them ideal for the most stringent analog requirement applications. With an effi-
cient, pipelined 8051 core with maximum operating frequency at 72 MHz, various com-
munication interfaces, and four channels of configurable logic, the EFM8LB1 family is
optimal for many embedded applications.
EFM8LB1 applications include the following:
• Optical network modules
• Precision instrumentation
• Industrial control and automation
• Smart sensors
