Voice broadcast chip solution, providing text content to voice conversion, functions can be single-wire, dual-wire, button, etc. The speaker can be directly pushed or an amplifier can be added. Development Considerations EMC Design The voice signal line must be grounded to avoid running parallel to high-frequency circuits. For direct push solutions, it is recommended that … Read more
In recent years, NPU (Neural Processing Unit) technology has rapidly developed, with major manufacturers launching a variety of high-performance AI acceleration chips to meet diverse needs from edge devices to cloud data centers. Below is a detailed description of NPU chips along with their core features and application scenarios: 1. Apple M3 Series Chips (M3/M3 … Read more
NAND Flash cannot achieve XIP, which is entirely determined by its underlying hardware implementation technology and interface standards, rather than something that can be easily changed by software or the operating system. This stands in stark contrast to NOR Flash, which supports XIP, with the core difference being the access interface and addressing method.Interface Bus:NOR … Read more
This article, in conjunction with the book “AI at the Edge“, introduces two additional types of hardware that can be used in edge AI devices: System-on-Chip (SoC) and Deep Learning Accelerators. SoC Following microcontrollers (MCU), the next most common type of edge computing hardware is System-on-Chip (SoC) devices. MCUs are streamlined, optimized versions of computers … Read more
iPhone 17 Features A19 Chip, Performance Boost of 20%? Test Results Are Out!—— Behind the single-core dominance, heat dissipation and ecosystem remain key variables💡IntroductionIn September 2025, Apple’s newly released iPhone 17 series sparked discussions due to its A19 chip. The official claim states a “significant performance improvement,” but does the test data support this conclusion? … Read more
In the previous two articles, we gained a preliminary understanding of the semiconductor fabrication process and left some questions unanswered. Today, let’s address three issues encountered in “Semiconductor Fabrication Processes”. If you have other opinions or views, feel free to leave comments for discussion. Q1:What are the process considerations behind the requirement for device orientation … Read more
As the “cornerstone” of the electronic information industry, the working principles of semiconductor devices conceal the underlying secrets of chip operation. Shi Min’s “Physics of Semiconductor Devices” is considered a classic in the industry, covering a complete knowledge system from the basics of semiconductors to MOS devices. Today, we will break down the core content … Read more
One of the core challenges of solid-state transformers (SST) is that the voltage withstand capability of individual power semiconductor devices is far from sufficient to directly handle the voltage levels of medium-voltage distribution networks (such as 10kV). Addressing this voltage limitation is not reliant on a single technology, but rather a set of “combinations“. The … Read more
