Highway09a Ic Datasheet __exclusive__ Jun 2026

Finding an official has proven difficult for many electronics professionals. In 2014, a forum user noted that a request for HIGHWAY09A pinout diagrams attracted over 600 views but only 5 replies, with none able to provide a complete datasheet, highlighting the scarcity of official documentation.

The IC is controlled via 8-bit registers:

: DIP-16 (Dual In-line Package with 16 pins). This standard form factor is preferred for prototyping and repairs due to its ease of soldering and efficient heat dissipation.

Due to its stability and performance, you’ll find the HIGHWAY09A in:

| Revision | Date | Description of Change | |----------|------------|-------------------------------| | 1.0 | 2024-05-10 | Initial release | | 1.1 | 2025-01-20 | Added DFN-8 package, EMIRR data | highway09a ic datasheet

: Authentic chips for repairs are commonly stocked on AliExpress . HIGHWAY09A Holtek | | Xecor

Beyond basic microcontroller functions, the HIGHWAY09A is described as a versatile integrated circuit designed for signal processing and control applications. It integrates simultaneous sampling with advanced multiplexing capabilities, making it suitable for multi-channel signal management in industrial automation and communication systems.

user wants a long, detailed article for the keyword "highway09a ic datasheet". This is a technical topic, so the article should be thorough and accurate. I need to gather comprehensive information about the Highway09A IC. I will follow the search plan as outlined. I'll start with the first set of searches. search results show various sources. I need to open the most promising ones to gather detailed information. I'll open result 0, 1, 2, 3, 4, 5, 7, and 8 from the first search, result 1 from the second, result 0 from the fourth, and result 3 from the fifth. search results provide a mix of sources. Some list the IC as a voltage regulator, but most indicate it's a microcontroller used in induction cookers. I have gathered information from various sources, including forums, distributor sites, and a Russian website. The information includes technical specs, pinout, reference designs, and details about the manufacturer. I will structure the article to cover: an introduction, overview and key features, manufacturer and origin, technical specifications, pinout and pin function table, absolute maximum ratings, application circuits and reference design, troubleshooting, procurement, and finally a conclusion. I will cite the relevant sources. The Complete Guide to the Highway09A IC: Datasheet, Pinout, Applications, and Troubleshooting Finding an official has proven difficult for many

: Integrated over-current, over-temperature, and reverse-battery protection. It also features Human Body Model (HBM) ESD safety margins. HIGHWAY09A Pin Configuration (PDIP16)

While the full internal schematic is typically restricted to the official manufacturer datasheet, the following characteristics are standard for this component type: Package Type : Typically available in a

Based on manufacturing documentation, the HIGHWAY09A features a One-Time Programmable (OTP) memory architecture, meaning that once the device is programmed, its firmware cannot be erased or rewritten. This is a critical consideration for repair applications where chip replacement may be necessary rather than reprogramming. This standard form factor is preferred for prototyping

The HIGHWAY09A is a microcontroller (MCU) with OTP memory, 4K×16 program space, 160 bytes RAM, and a 12-bit ADC. Some distributor listings incorrectly describe it as a voltage regulator—these are errors.

Dictates the maximum duty-cycle window permissible for the driving output stages.

: Designed to operate within standard industrial temperature ranges (often -20°C to +85°C) to ensure safety during high-heat induction cycles. Protection Systems
