8 bit RISC MCU
FMD has been focusing on developing 8-bit MCU with high performance, high reliability and high cost performance. Based on the market demand, the company constantly develops new product and provide optimal solutions. Currently, FMD 8-bit MCU includes three types of I/O, A/D and Touch, which can apply to all kinds of consumer product application field and meet different demand of customers. FMD 8-bit MCU has built-in 16Mhz high-speed RD oscillator and data EEPROM and peripherals, such as Timer, PWM, ADC, analog comparator, low voltage reset, I²C and etc. Besides, FMD 8-bit MCU also supports ISP and online debugging, which further facilitates the development.
We protect your firmware by offering R/W program and data EEPROM protections, and custom key for hex encryption/code execution.
Multiple safeguards during BOOT, including check sum, improves startup robustness. Our self-regulated POR technology means as long as the voltage is above VPOR the MCU can run at 8M/4T or above, saving the needs for cumbersome power supply detection and regulation. This also allows some of our chip to function at as low as 1.5V in battery operation environment. Couple with our generally low operating current, we can extend battery life up to 40% over some of our competitors. Our special low power mode uses as low as 8uA running at 32 kHz.
FMD have products with program sizes from 1k x 14 to 16k x 16, 6 pins to 48 pins, simple I/O types to higher end offering 12-bit ADC, LCD drivers, highly robust touch keys, I2C, UART, SPI interfaces, multiple timers, multi-channel versatile PWM, comparators, DAC, low end sensing up to 0.0125mV resolution, 13.56MHz carrier wave, 3.2V – 4.7V monitoring for Lithium battery, multiple stages current drives. Our MCU find their way into every day products, from small toys, wireless charging, home appliances, smart everything to powerful BLDC. Reliable and versatile doesn’t mean high price. We offer one of the industrial better price-performance NVM based MCU. We work hard to save on external BOM too. FMD ships over 150 million pieces of EEPROM and MCU every month, so don’t be surprise if there are a few of our chips in your home!
