EFM8SB1

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. 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. EFM8SB1 applications include the following: Touch pads / key pads Wearables Instrumentation panels Battery-operated consumer electronics ENERGY FRIENDLY FEATURES Lowest MCU sleep current with supply brownout (50 nA) 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) Ultra-fast wake up for digital and analog peripherals (< 2 μs) Integrated LDO to maintain ultra-low active current at all voltages Core / Memory CIP-51 8051 Core (25 MHz) Flash Program Memory (up to 8 KB) RAM Memory (up to 512 bytes) Debug Interface with C2 Clock Management External Oscillator Low Power 20 MHz RC Oscillator Low Frequency RC Oscillator High Frequency 24.5 MHz RC Oscillator External 32 kHz RTC Oscillator Energy Management Internal LDO Regulator Power-On Reset Brown-O...
