EFM8 Sleepy Bee Family
EFM8SB2 Data Sheet
The EFM8SB2, part of the Sleepy Bee family of MCUs, is the
world’s most energy friendly 8-bit microcontrollers with a comprehensive feature set in small packages. ENERGY FRIENDLY FEATURES • Lowest MCU sleep current with supply
brownout detection (50 nA) These devices offer lowest power consumption by combining innovative low energy techniques and short wakeup times from energy saving modes into small packages, making
them well-suited for any battery operated applications. With an efficient 8051 core, 6-bit
current reference, and precision analog, the EFM8SB2 family is also optimal for embedded applications. • Lowest MCU active current with these
features (170 μA / MHz at 24.5 MHz clock
rate) EFM8SB2 applications include the following: • Ultra-fast wake up for digital and analog
peripherals (< 2 μs) • Battery-operated consumer electronics
• Sensor interfaces • Hand-held devices
• Industrial controls Core / Memory RAM Memory
(4352 bytes) (up to 64 KB) • Integrated low drop out (LDO) voltage
regulator to maintain ultra-low active
current at all voltages Clock Management CIP-51 8051 Core
