EFM8LB12F64E-A-QSOP24R

The EFM8LB12F64E-A-QSOP24R is an 8-bit, low-powerembedded microcontroller with configurable GPIO, Flash Memory, RAM, peripherals, and USB-OTG support. As an 8-bitmicrocontroller, it can be suited for running low-power applications such as data acquisition, automation or control systems, or embedded networking applications such as Internet of Things (IoT) projects. It is well suited for applications that require long periods of run-time under limited power supply.

The EFM8LB12F64E-A-QSOP24R includes 64kB of Flash memory and 4kB of RAM. It incorporates an 8051 architecture with multiple sub-systems and on-chip peripherals for configuring a fully-featured system. The integrated hardware includes two UARTs, one SPI, two I2Cs, two timers/counters for PWM signals, two Advanced High-Speed Capture/Compare Units (CHS) for comparing pulse width signals, one Pulse Width Modulator (PWM), one Analog Comparator (AC), one Real-Time Clock (RTC) and one watchdog timer (WDT). It also contains a module for configuring micropower operation, allowing the EFM8LB12F64E-A-QSOP24R to achieve very low-power consumption in both active and sleep modes.

The EFM8LB12F64E-A-QSOP24R is designed to meet the demanding requirements of IoT applications. It offers ample peripherals and interfaces with USB OTG support on a single device. The USB OTG support provides the option to connect to the host board directly or to an external transceiver. It also features advanced peripheral support and an integrated sleep power reduction mode that can be enabled in software. To support low-level embedded application requirements, the device integrates 6-channel 10-bit ADC along with 4-channel 16-bit PCA for PWM signals.

In addition to its wide range of hardware features, the EFM8LB12F64E-A-QSOP24R includes an on-chip 8-bit microprocessor. The processor incorporates an array of 8-bit registers, including PC, AX, BX, CX, DX, SP, BP, SI and Dl. The instruction set includes multiple call and jump instructions plus six arithmetic and logical operations - ADD, SUB, CMP, OR, AND, XOR. The arithmetic and logical operations allow for manipulation of the 8-bits stored in the registers, enabling the development of lower-level programs that are capable of performing complex calculations.

The EFM8LB12F64E-A-QSOP24R features a number of features that support low power operation. The power management module, which is integrated into the device, can reduce power consumption by varying the clock speed, allowing the processor to operate at lower speeds when not needed and to intensify processing when required. The on-chip low-dropout (LDO) regulator reduces component count and power consumption, while the internal power-on reset keeps the system in the standby mode until a power-on reset occurs. Additionally, the device includes a power saving mode that allows the user to selectively suspend the microcontroller’s clock and save power when it is not in use.

Overall, the EFM8LB12F64E-A-QSOP24R is a highly-integrated, low-power microcontroller designed to address the needs of embedded IoT applications. The device integrates a multitude of peripherals and interfaces along with low-power management features. Its compact size and cost-effectiveness, combined with its low-power and good performance make it an ideal choice for embedded applications.
