in detailThe HT46R002 is a versatile Microcontroller Unit (MCU/ MPU/SOC) manufactured by Holtek, specifically the RISC architecture. It features an 8-pin SOIC (Small Outline Integrated Circuit) package and is ROHS compliant. Its on-chip memory consists of 64 bytes OTP (One Time Programmable) memory and 1KB program ROM for program storage and execution. It is equipped with up to 8K Bytes of SRAM to store the state of the system and user data. Additionally, it houses an internal 4K bytes EEPROM for internal data and storage.It also comes with a comprehensive set of peripheral features, which include up to two 32-bit Timers/Counters, an 8-channel 10-bit A/D Converter(ADC), a 3-level Watchdog Timer (WDT), a 4-level Brown-Out Detector (BOD), two I/O ports (Ports A and B), an Ethernet MAC, a Communications Interface (CI) module, a low power oscillator and a precision integrated oscillator.The MCU also has a 4-level Voltage Detection (VD) circuit, a temperature detector, an internal power-on reset and a sequence controller. It is also capable of supporting the I2C, ?, and UART serial communication standards. Last but not the least, it is equipped with a number of integrated power-saving features and has a low-power operating voltage range of 1.8V-3.6V.
