EFM8 Sleepy Bee Family
EFM8SB1 Data Sheet
The EFM8SB1, 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 (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, 14
high-quality capacitive sense channels, and precision analog, the EFM8SB1 family is also optimal for embedded applications. • Lowest MCU active current (150 μA / MHz
at 24.5 MHz)
• Lowest MCU wake on touch average
current (< 1 μA)
• Lowest sleep current using internal RTC
and supply brownout (< 300 nA) EFM8SB1 applications include the following: Core / Memory RAM Memory
(up to 512 bytes) (up to 8 KB) • Integrated LDO to maintain ultra-low
active current at all voltages Clock Management CIP-51 8051 Core
