Epson launches a 16 bit MCU product for high current LED drives

In the past, most of Epson's microprocessors inherited LCD driver circuits, but recently, with the significant increase in the number of 7-segment LED displays used in industrial automation and household equipment, Epson has also launched corresponding products to meet customer requirements for bright and self luminous displays.

However, in order to maintain the brightness of the display, LEDs typically require a driving current of 10mA. This becomes difficult for current low voltage and low-power microprocessors, often requiring the addition of additional driver circuits to achieve. In addition, users also need to develop control software to achieve the display of multiple numbers.

S1C17M13 is designed to address the aforementioned issues. Its working voltage ranges from 1.8V to 5.5V, making it convenient for industrial automation equipment that supports 5V interfaces. The chip provides 5 pins that can output 56mA. By combining these high-level output common terminals with an additional 8 SEG pins, users can drive up to 8seqx5com segmented LED displays without the need for additional transistors on the common terminal.

Moreover, this MCU integrates dynamic lighting control hardware circuits. Users can choose any segment of the display, fine tune the display refresh cycle, and adjust the brightness level 4 through simple software settings, which greatly reduces the difficulty and development cycle of user development.

·In addition, S1C17M13 is equipped with 16KBflash ROM and 2KB RAM. On the peripheral interface, 12 bit ADC, 16bitTimersPWM, WDT, SPI, I2C, UART, power supply voltage detection SVD, and infrared carrier transmission IR are all standard equipment.
