The EFM8SB20F32G-B-QFN24R, part of Silicon Labs' Sleepy Bee family, is an energy-friendly 8-bit microcontroller designed for low-power applications. It features a CIP-51 8051 core operating at up to 25 MHz, with 32KB of FLASH program memory and 4.25KB of RAM.
This microcontroller boasts innovative low-energy techniques, including a lowest MCU sleep current of 50 nA with brownout detection and active current of 170 μA/MHz. It offers ultra-fast wake-up times of less than 2 μs for digital and analog peripherals. The device operates within a voltage range of 1.8V to 3.6V and has an operating temperature range of -40°C to 85°C.
Key peripherals include 15 channels of 10-bit Analog-to-Digital converters, I²C, SMBus, SPI, and UART/USART communication interfaces. It also includes essential peripherals like a Brown-out Detect/Reset circuit, Power-On Reset (POR), Pulse Width Modulation (PWM), and a Watchdog Timer (WDT). The EFM8SB20F32G-B-QFN24R is supplied in a compact 24-QFN (4x4) package, suitable for surface mounting.
