Product Specifications

Technical details and manufacturing context for Microcontroller/Encoder

Definition
This product is an integrated electronic component that combines a microcontroller and an encoder in a single package, designed for use in wireless transmitters and similar control applications. The microcontroller serves as the central processing unit, executing programmed instructions for data handling, protocol management, and system control. The encoder converts digital signals into formats suitable for wireless transmission, such as pulse sequences or modulated signals, ensuring data integrity and efficient communication. The integration allows synchronized operation, where the microcontroller controls encoding parameters and timing based on transmission requirements.

The component is manufactured using silicon semiconductor technology with copper interconnects and a ceramic substrate, providing reliable electrical performance and thermal stability. It is available in surface-mount packages (QFN-32 to QFP-100) and operates within a supply voltage range of 3.3–5 V DC. The operating temperature range is -40 to 85 °C (industrial grade, with extended ranges available). The microcontroller supports clock frequencies from 8 to 80 MHz, with flash memory from 16 to 512 KB and SRAM from 2 to 64 KB. The encoder offers resolutions from 8 to 16 bits per channel, with an accuracy of ±0.5 degrees for position sensing. Communication interfaces include I2C, SPI, and UART, and the component provides 8 to 48 configurable GPIO pins. An analog-to-digital converter with 10 to 12-bit resolution is integrated. Power consumption in active mode at 3.3 V ranges from 1 to 50 mA. The component has an ingress protection rating of IP54 to IP65 (per IEC 60529) and weighs between 0.5 and 5 grams.

These specifications are typical reference ranges for the product family; actual values vary by specific model and application. Always verify model-specific parameters and standards with the legal manufacturer or supplier before procurement or integration.
Working Principle
The microcontroller executes programmed instructions to process input data and manage communication protocols. It controls the encoder's parameters and timing based on transmission requirements. The encoder converts the processed digital data into specific signal formats, such as pulse sequences or modulated signals, suitable for wireless transmission. The integrated design ensures synchronized operation, where the microcontroller and encoder work together to maintain data integrity and efficient communication. The component's interfaces (I2C, SPI, UART) allow external communication, and its GPIO pins enable configuration and control. The ADC converts analog signals for processing, and the encoder provides position or rotational data with specified resolution and accuracy.
