Source: Semiconductor Industry Observer Compared to many computer technologies, the development history of flash memory is relatively short, but it can be said to have rapidly grown in response to the demands of a huge and rapidly changing storage market.Originating in the late 1960s, the concept was proposed in the early 1980s, and it has … Read more
PCBA (Printed Circuit Board Assembly) refers to the process of mounting electronic components on a printed circuit board (PCB) to form a complete electronic product.PCBA is fundamental to the electronics industry, as nearly all electronic devices are composed of PCBA. The quality and performance of PCBA directly affect the lifespan, speed, stability, and reliability of … Read more
AT28C64B-15PU is a classic 64Kbit electrically erasable parallel EEPROM launched by ATM, packaged in a DIP28 form factor. This chip features a 150ns access time and provides an 8K×8 bit storage structure. As a fundamental product of electrically erasable memory, the AT28C64B-15PU supports in-system electrical erasure and programming, boasting high reliability and long lifespan characteristics. … Read more
1. First, set to “Modbus RTU protocol” through [Pr.PC71].Set the “Control Mode Selection” of [Pr.PA01] to program control mode.2. Set the homing reset mode at address 6098H (for example, the commonly used return method with DOG search).3. Save the manufacturer-defined parameters in EEPROM at address 1010H, then power off and restart.4. In Point Table Mode, … Read more
“ Mastering storage means mastering embedded systems!” It is well understood by all engineers engaged in embedded development that storage plays a very important role in technology and products. Common storage types include RAM, Flash, and ROM. RAM is primarily used to store runtime programs and data, which needs no further explanation. 01 — Flash … Read more
Description I2C supports N-2-N on the bus, so addresses are needed to distinguish devices. A complete transmission always starts with a START signal followed by the device address and the read/write flag. Device Address So how do we view and define the device address? The device address corresponds to the first BYTE’s BIT7-BIT1, with BIT … Read more

Memory is divided into two main categories: RAM and ROM, with a focus on ROM here.ROM was originally non-programmable, meaning whatever content it had when it left the factory was permanent and inflexible.Later, PROM was developed, which could be written once; if a mistake was made, the chip had to be replaced, leading to unfortunate … Read more
Introduction In embedded development, the persistence of stored data is crucial. The ESP32 offers various storage options, with flash memory being the most commonly used medium. However, flash memory has a limited number of write cycles, and frequent writes can shorten its lifespan. In particular, the EEPROM implementation of the ESP32 stores data in the … Read more
