HT48R05A-1

General Characteristics

• Core: It adopts the Holtek 8 – bit MCU core, which has a relatively simple structure and is suitable for some applications with moderate processing requirements. It can perform basic arithmetic and logical operations to meet the control needs of various simple electronic systems.
• Memory: Usually, it has a certain amount of program memory and data memory. The program memory is used to store the user – written control program, which enables the microcontroller to perform specific tasks according to the set instructions. The data memory is used to store temporary data during program execution, such as variables, intermediate results, etc.
• Operating Voltage: The operating voltage range is generally 2.2V to 5.5V. This wide voltage range allows it to be applied in different power supply environments. Whether it is a battery – powered portable device or a device powered by a stable power supply, it can work stably.
• Operating Frequency: The operating frequency can be adjusted according to the specific application requirements. It can generally work at a relatively low frequency to save power consumption, or work at a higher frequency to meet the needs of applications that require faster processing speed.

Peripheral Functions

• I/O Ports: It is equipped with multiple general – purpose input/output ports. These ports can be flexibly configured as input ports to receive external signals, such as the status signals of buttons, sensors, etc., or as output ports to control external devices, such as LEDs, relays, etc. Through software programming, the functions of each I/O port can be freely defined to meet the specific needs of different applications.
• Timers/Counters: It has built – in timer and counter functions. The timer can be used to generate accurate time delays, realize functions such as timing control and scheduling, and is widely used in applications such as blinking lights and regular data sampling. The counter can be used to count external events, such as the number of pulses of a rotating encoder, so as to realize functions such as speed measurement and position detection.
• Serial Communication Interfaces: Some models may be equipped with serial communication interfaces, such as UART (Universal Asynchronous Receiver/Transmitter). This interface enables the microcontroller to communicate with other devices, such as computers, other microcontrollers, or serial – communication – enabled sensors. It can realize functions such as data transmission and remote control, and is convenient for the expansion and networking of the system.

Applications

• Consumer Electronics: It is widely used in various consumer – electronics products, such as remote controls, electronic toys, and small – household – appliance controllers. In remote controls, it is used to receive button – press signals and convert them into infrared signals to control the corresponding electrical appliances. In electronic toys, it can control the movement, sound, and light effects of toys to provide rich interactive experiences. In small – household – appliance controllers, such as fan controllers and electric – kettle controllers, it realizes functions such as temperature control and timing.
• Industrial Control: It can also be applied to some simple industrial – control scenarios, such as single – chip machine – based control systems for small – scale production lines and simple process – control equipment. It can monitor and control some basic process parameters, such as temperature, humidity, and pressure, and realize simple logic control and sequence control.
• Medical Equipment: In some simple medical – equipment applications, such as portable medical monitors and simple medical – device controllers, the HT48R05A – 1 can also play a role. It can collect physiological data through sensors and perform simple data processing and display, providing basic technical support for some low – end medical equipment.
