EFM8LB12F64E-C-QFN32R 詳細描述
Product Overview
The EFM8LB12F64E-C-QFN32R from Silicon Labs is a Laser Bee 8-bit microcontroller built around the CIP-51 8051 core and supplied in a 32-QFN (4x4) surface-mount package. It provides 64KB (64K x 8) FLASH program memory, 4.25K x 8 RAM, and operates from a 2.2V to 3.6V supply with a 72MHz speed. The device includes 29 I/O pins, an internal oscillator, and a temperature range of -40°C to 105°C (TA). Its on-chip connectivity includes I2C, SMBus, SPI, and UART/USART interfaces, while analog resources include 20 14-bit A/D channels and 4 12-bit D/A channels.
Key Features
- 8-bit CIP-51 8051 core with a 72MHz speed.
- 64KB (64K x 8) FLASH program memory and 4.25K x 8 RAM.
- 29 I/O pins in a 32-QFN (4x4) exposed-pad surface-mount package.
- I2C, SMBus, SPI, and UART/USART communication interfaces.
- 20 14-bit A/D channels and 4 12-bit D/A channels.
- Brown-out detect/reset, POR, PWM, and WDT peripherals.
- Internal oscillator and 2.2V to 3.6V supply range.
Applications
- Embedded systems that need serial communication with peripherals over I2C, SMBus, SPI, or UART/USART.
- Mixed-signal control nodes using 14-bit A/D inputs and 12-bit D/A outputs.
- PWM-controlled output applications with on-chip reset, brown-out, and watchdog support.
- Compact surface-mount embedded designs operating from 2.2V to 3.6V over -40°C to 105°C (TA).
Design & Procurement Notes
When selecting this device, verify that the PCB footprint matches the 32-QFN (4x4) and 32-UFQFN exposed pad, and that the system supply remains within 2.2V to 3.6V. The internal oscillator may reduce external clock components, but the 72MHz core speed and 29 I/O pins should be checked against the required interface count and timing budget. The 64KB FLASH and 4.25K x 8 RAM sizes define the available program and data space. The 20 14-bit A/D and 4 12-bit D/A resources make it useful for designs needing on-chip analog conversion, while the Active lifecycle status can be used for procurement planning.
