The HT48R54A is a newly developed 8-bit high-current LED-driven I/O-type microcontroller from HOLTEK Semiconductor with up to 40 input/output pins. Port D and Port E can drive 40mA at a working voltage of 5V. Can 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 LE D applications, it is also suitable for all types of home appliances, consumer products and other intelligent control products.
HOLTEK Semiconductor also provides HT-IDE3000, a full-featured development system for hardware and software, including real-time emulation, memory buffer storage, hardware breakpoint logic setting, execution trace analysis, etc., suitable for faster and more efficient development. Program and debug users for product development.
