EFM8LB12F64E-C-QFN24R 詳細描述
Product Overview
The EFM8LB12F64E-C-QFN24R from Silicon Labs is an 8-bit microcontroller built around a CIP-51 8051 core and packaged in a 24-QFN (3x3) surface-mount package. It provides 64KB (64K x 8) FLASH program memory, 4.25K x 8 RAM, and a 72MHz operating speed with an internal oscillator. The device integrates 20 I/O pins, I2C, SMBus, SPI, and UART/USART interfaces, along with PWM, brown-out detect/reset, POR, and watchdog timer peripherals. It also includes 12-channel 14-bit ADC and 4-channel 12-bit DAC converters, and operates from 2.2V to 3.6V over -40°C to 105°C (TA).
Key Features
- 8-bit CIP-51 8051 core with 72MHz speed and internal oscillator.
- 64KB (64K x 8) FLASH program memory and 4.25K x 8 RAM.
- 20 I/O pins with I2C, SMBus, SPI, and UART/USART communication interfaces.
- Integrated PWM, brown-out detect/reset, POR, and watchdog timer peripherals.
- 12-channel 14-bit ADC and 4-channel 12-bit DAC converters.
- 2.2V to 3.6V supply range and -40°C to 105°C (TA) operating temperature.
- 24-QFN (3x3) surface-mount package with exposed pad.
Applications
- Embedded control subsystems requiring an 8-bit microcontroller with mixed-signal conversion resources.
- Sensor or signal-conditioning nodes that use ADC and DAC channels with serial communication.
- Compact board-level controllers needing I2C, SMBus, SPI, or UART interfaces and watchdog/POR features.
Design & Procurement Notes
Designers should verify power, signal, and layout requirements against the 2.2V to 3.6V supply range, 20 I/O count, 24-QFN (3x3) exposed-pad footprint, and -40°C to 105°C (TA) operating temperature. The internal oscillator, FLASH program memory size, RAM size, converter channel counts, and communication interfaces should be checked against the target firmware and board-level connectivity plan. Procurement notes should focus on confirming the 24-QFN (3x3) footprint, exposed-pad thermal path, and voltage range compatibility with the board power architecture.
