Microchip’s tinyAVR® family of microcontrollers with Core Independent Peripherals (CIP), high-speed internal oscillators and event systems has been widely admired. Microchip’s newly launched megaAVR® MCU – ATmega4809 series has larger storage capacity and more pins, and is an expansion of the tinyAVR series. This new ATmega4809 series is an ideal auxiliary MCU for complex systems […]
What is a Digital Signal Processor? A digital signal processor (DSP) is a microprocessor dedicated to (usually real-time) digital signal processing. The architecture includes CPU/ALU, program memory, data memory, etc. Its common architecture types include enhanced DSP, VLIW structure, superscalar architecture and SIMD structure hybrid structure. Its biggest feature is its internal dedicated hardware multiplier
Components of Embedded Hardware Systems: Processor, Memory (RAM/ROM), I/O Devices, Analog/Digital Conversion Units (A/D, D/A), Communication Modules, Power Modules. This article provides a detailed introduction to the core unit of embedded hardware systems: the processor. Types of Embedded Processors Micro Control Unit (MCU) STM32 MCU Embedded microcontrollers, also known as single-chip microcontrollers, integrate the entire
8051 MCU The 8051 MCU is the most widely used 8-bit microcontroller, originally developed by Intel in 1980. Its typical architecture, centralized management of dedicated bus registers, numerous bitwise operations, and rich instruction set for control applications make it a first-generation “classic,” laying the foundation for the development of other microcontrollers in the future. 8051-MCU
The STM8 microcontroller series, introduced by STMicroelectronics in 2009, is a range of 8-bit microcontrollers built around the advanced STM8 core. These microcontrollers feature a 3-stage pipelined architecture, high cost-effectiveness, and ease of development. Depending on the application requirements, the STM8 microcontroller series is divided into three main categories: STM8S, STM8L, and STM8A. Features of
