 Holtek HT48R06xD HT46R06xD high current drive LED series MCU. Family members of the HT48R06xD series of three family members of HT46R06xD series 3, respectively HT48R064D HT46R064D can drive 32 LEDs directly, HT48R065D, HT46R065D, HT48R066D and HT46R066D direct drive 64 LEDs. LED drive current of the Sink the Current 60mA, the Source the Current-20mA HT46R06xD built-in 12-bit A / D and 8-bit PWM, can reduce the peripheral parts to shrink the PCB Size and reduce costs, ideal for all kinds of small household electrical appliances, the class panel with LED display. 


 Characteristics of HT48R06xD and HT46R06xD is a full range of work regulation (-40 to 85 ° C), 2.2 ~ 5.5V operating voltage, built-in LCD COM, R-Type, the LED drive current functionality, reuse and maximize I / O functions, fast 12-bit A / D and PWM, built-in high precision RC oscillator circuit, sleep wake up fast, the level of dual-band system operating switch and a full range of the RTC and other features, in fact, features, performance and the most competitive prices MCU family. The whole range of features cover a wide range to meet customer demand for end products, especially suitable for small household electrical appliances, example: straight hair, rice cooker, electric fan, soybean milk, chargers, vacuum cleaners and so on. Cost-effective products more and more market attention, this series is to provide users an excellent cost-effective small appliances solutions. 


 This product has a high anti-noise characteristics of the Holtek other 8-bit MCU watchdog (Watchdog) and LVR function is to strengthen the ability of the MCU anti-crash. At present HT4xR064D 16DIP/NSOP, and 20DIP/SOP packaging; HT4xR065D provide the the 16DIP/NSOP, 20DIP/SOP and 24SKDIP/SOP packaging; HT4xR066D the 20DIP/SOP, 24SKDIP/SOP and 28SKDIP/SOP packaging, and give users the option elasticity.
