Sheng group launched the new eight bit high current LED driver I/O microcontroller

HT48R54A Holtek semiconductor (Holtek Semiconductor) eight high current LED new development driven I/O micro controller, with as many as 40 input / output pins, the current Port D and Port E can drive 40mA in the operating voltage of 5V, the most direct driving up to 256 LED.

HT48R54A has 15 4K * 192 * 8 OTP program memory, data memory, 40 I/O, 2 8-bit Timer, 3-levEL Low Voltage, Reset PFD/Buzzer and 6-level Stack and other specifications, to provide users with more efficient programming function, provide the package of 44 QFP and 52 QFP in the package, which can provide samples and enter the mass production stage.

HT48R54A has a very low power operation, when the system frequency is 32768Hz Real Time Clock, working current of 20uA (3V), and enter the power saving mode, the Real Time Clock continued to work at HT48R54A 1uA (3V) current consumption only, it can prolong the use time of the battery. On the other hand, the utility model has a plurality of power supply and ground pins, which can effectively disperse the current supply.

HT48R54A can directly drive LED display device or used to control a variety of switches, saving the number of external components, suitable for the growing popularity of all kinds of LED applications. In addition to LED applications, but also for all types of home appliances, consumer products and other intelligent control products.

Holtek semiconductor also provides hardware and software functional development of HT-IDE3000 system, including real-time simulation, memory / cache access, hardware breakpoint set logic, execution trace analysis and so on, the need for more rapid and more efficient to develop and debug the program used for product development.
