Eight-bit high current LED driven I/O type microcontroller available
Holtek's newly developed eight-bit high-current LED-driven I/O-type microcontroller with up to 40 input/output pins, of which Port D and Port E can drive 40 mA at an operating voltage of 5 V. Directly push up to 256 LEDs.
HT48R54A has 4K×15 OTP program memory, 192×8 data memory, 40 I/O, 2 8-bit Timer, 3-level Low Voltage Reset, PFD/Buzzer and 6-level Stack. Efficient program-controlled features, available in package sizes of 44 QFP and 52 QFP packages, are now available for sample and mass production.
The HT48R54A has extremely low operating power. When the system frequency is 32768Hz Real Time Clock, the operating current is 20uA (3V). After entering the power saving mode, the Real Time Clock continues to work. At this time, the HT48R54A consumes only 1uA ( 3V), so you can extend the battery life. On the other hand, it has multiple power supplies and grounding pins to effectively distribute the current supply.
The HT48R54A can directly drive LEDs and other display devices or to control various switches, saving the number of external components, and is suitable for a wide range of LED applications. In addition to LED applications, it is also suitable for all types of home appliances, consumer products and other intelligent control products.
Holtek also offers the HT-IDE3000, a full-featured development system for hardware and software, including real-time emulation, memory/buffer storage, hardware breakpoint logic settings, execution trace analysis, etc., suitable for faster and more efficient applications. Development programs and debuggers for product development.
