What's So Great About Japan's Semiconductors?

★ Welcome to the hard technology of Guokey. ★ Japan’s semiconductor industry is no longer as powerful as it was in the 1980s, but its ambitions remain. On April 25, the Japanese government provided an additional subsidy of 260 billion yen to the domestic semiconductor company Rapidus, bringing the total investment to 330 billion yen … Read more

Why Do Microcontrollers Have So Little RAM?

Why Do Microcontrollers Have So Little RAM?

You must be curious: mobile phone memory (RAM) often reaches 8G or 12G, but why do microcontrollers have less than 1M of RAM? To understand, the classic AT89C51 microcontroller has only 128 bytes of RAM (memory). Similarly, the classic MSP430F149 also has only 2K of RAM space. Even the STM32F1 series, which is commonly used … Read more

Essential Knowledge for Embedded Design: How to Run Programs on Expanded SDRAM with MCU?

Essential Knowledge for Embedded Design: How to Run Programs on Expanded SDRAM with MCU?

In the design of embedded systems using MCU, when the program or data memory is too large to fit into on-chip flash or SRAM, developers often consider using SDRAM. Don’t ask me why your MCU doesn’t support SDRAM SDRAM stands for Synchronous Dynamic Random Access Memory. In microcontroller applications, the microcontroller accesses SDRAM using an … Read more
