The Holtek HT46R003B NSOP-16 RoHS manufactured by Holtek is a microcontroller IC intended for use in smart systems control applications like micro-motor, OLED drive, and others. It features a 8-bit RISC-type core that can support up to 8MHz clock speed, an RTC calendar and clock, 2K bytes of ROM, 8K bytes of RAM, 6 channels of 8-bit A/D converter, and 6 channels of 16-bit PWM. It has an almost asset pin-to-pin compatibility feature, allowing developers to use the same development tools for the Holtek HT46R003B as those used for the HT46R002A and others. It is RoHS and is housed in NSOP16 (Nano Surface Mounted Laser Package) package.
