Overview
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.
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.
EFM8SB2 applications include the following: • Hand-held devices • Industrial controls • Battery-operated consumer electronics • Sensor interfaces ENERGY FRIENDLY FEATURES • Lowest MCU sleep current with supply brownout detection (50 nA) • Lowest MCU active current with these features (170 μA / MHz at 24.
5 MHz clock rate) • Lowest MCU sleep current using internal RTC operating and supply brownout detection (<300 nA) • Ultra-fast wake up for digital and analog peripherals (< 2 μs) • Integrated low drop out (LDO) voltage regulator to maintain ultra-low active current at all voltages Core / Memory CIP-51 8051 Core (25 MHz) Clock Management External Oscillator Low Power 20 MHz RC Oscillator Energy Management Internal LDO Regulator Power-On Reset Flash Program Memory (up to 64 KB) RAM Memory (4352 bytes) Debug Interface with C2 External 32 kHz RTC Oscillator High Frequency 24.
5 MHz RC Oscillator Brown-Out Detector Serial Interfaces UART 2 x SPI I2C / SMBus I/O Ports External Interrupts Pin Reset General Purpose I/O Pin Wakeup 8-bit SFR bus Timers and Triggers Timers 0/1/2/3 PCA/PWM Watchdog Timer Real Time Clock Analog Interfaces ADC Comparator 0 Comparator 1 Internal Voltage Reference Internal Current Reference Security 16/32-bit CRC Lowest power mode with peripheral operational: Normal Idle Suspend Sleep silabs.
