STC15W4K56S4-30I-LQFP32
Enhanced 1T 8051 single-chip microcomputer microcontroller MCU
Product Description
A single-chip microcomputer, also known as a single-chip microcontroller, is not a chip that performs a specific logical function, but rather integrates a computer system onto a single chip. It is equivalent to a miniature computer. Compared with a computer, a single-chip microcomputer only lacks I/O devices. In a nutshell: A chip becomes a computer. It is small in size, light in weight and low in price, providing convenient conditions for learning, application and development. At the same time, learning to use a single-chip microcomputer is a good choice for understanding the principles and structure of computers.
