　　Naming rules for IC products: The first letters of most IC product models, which are usually called prefixes, are the first two or three letters of the manufacturer. For example, MAXIM\'s prefix is MAX, AD\'s prefix is AD, ATMEL\'s prefix is AT, CY\'s prefix is CY, and IC product models of companies like AMD, IDT, LT, DS, and HY are prefixed with the first two or three letters of the manufacturer. But there are many manufacturers that are not like this, such as TI\'s generally prefixed with letters such as SN, TMS, TPS, TL, TLC, and TLV; ALTERA, XILINX, and Lattice are called programmable logic devices CPLD and FPGA. ALTERA\'s prefixes are EP, EPM, and EPF, and it sells better in Asian countries. XILINX\'s prefix is XC, and it sells better in European countries and has quite good functions. Lattice generally has M4A, LSP, and LSIG as prefixes, and NS\'s prefix is mostly LM, etc., so I won\'t introduce them one by one here.
