The Willar Programmer (often referred to as WLPRO or Willer Software) is a specialized utility used for burning .hex files onto 8051-series microcontrollers and EEPROM devices. While the software was originally designed for older versions of Windows, it can still be utilized on Windows 10 with specific configuration steps, particularly regarding USB drivers and COM port assignments. Core Functionality and Supported Devices
The Willar Programmer is primarily a "fusing" tool used alongside development environments like Keil C51. It supports a variety of chips, including: Atmel 89 Series: AT89C51, AT89C52, AT89S51, AT89S52. Winbond: W78E51, W78E52. SST: SST89C54, SST89C58. EEPROM: Various 24 and 93 series serial EEPROM ICs. Software Features
High-Speed Writing: Capable of writing an 8KB flash file in approximately 10 seconds.
Auto-Detection: The software can automatically identify a connected programmer.
ZIF Socket Support: Designed to work with hardware featuring a 40-pin ZIF (Zero Insertion Force) socket for easy chip placement.
Integrated Verification: Built-in error checking, blank check, and program verification. Downloading the Software
Official distribution for this legacy tool is often through hardware vendors. Reliable download locations include:
Direct Drive Link: Some distributors provide a Google Drive link for the software.
Manufacturer Portals: NSK Electronics provides the software as an executable (.EXE) that can be run directly from your desktop.
Legacy Mirrors: Older versions like WLPRO V2.20 can be found on archives like EEWORLD. How to Use on Windows 10
To ensure the software functions correctly on Windows 10, follow these setup requirements:
Install USB-to-UART Drivers: Most Willar-compatible programmers use the CP2102 chip. You must download and install the Silicon Labs VCP Drivers for the device to be recognized. Assign COM Port: willar programmer software for windows 10 link
Open Device Manager and locate "Silicon Labs CP210x USB to UART Bridge" under Ports (COM & LPT). Right-click, select Properties > Port Settings > Advanced.
Change the COM Port Number to a value below 5 (e.g., COM1, COM2, COM3, or COM4), as the software often fails to detect ports higher than 5 automatically.
Run the Software: The software does not typically require a full installation. Simply copy the .exe file to your desktop or C: drive and run it as an administrator. Flash the Hex File: Select your target device (e.g., AT89S52). Click Load to browse for your .hex file.

Willar Programmer is a lightweight, specialized utility used to program various microcontrollers, primarily the 8051 and AVR families. It is commonly associated with hardware like the , SP200SE , and programmers. Software Download Links
The software is often distributed via third-party repositories and vendor support pages rather than a single official portal.
WLPRO Software: Available for download through Hacktronics or Rare Components.
Third-Party Host: A version can also be found on Software Informer. Drivers : You will likely need the Silicon Labs CP210x USB to UART Bridge drivers, which can be found on the Silicon Labs website. Key Features
Device Support: Compatible with Atmel 89 series (89C51, 89C52, 89S51, 89S52), serial EEPROMs (24 and 93 series), and some AVR microcontrollers.
Core Operations: Supports loading hex files, reading, writing, erasing, and verifying data on target chips.
"Auto" Mode: Features a one-click function to perform erase, blank check, program, and verify operations sequentially. The Willar Programmer (often referred to as WLPRO
Interface: Provides a task-focused UI with clear progress feedback and "Online Mode" indicators. Windows 10 Compatibility & Setup Tips
While originally designed for older Windows versions, the software can run on Windows 10 with these critical adjustments:
COM Port Limitation: The software often requires the hardware to be assigned to a single-digit COM port (e.g., COM1 to COM9). You can change this in Windows Device Manager under Port Settings > Advanced.
Online Mode: Ensure the software displays "ONLINE MODE" at the bottom of the screen before attempting to program; if it shows "DEMO MODE," it will not detect your hardware.
Executable Name: The main application file is typically named WLPRO.exe. Willar Programmer Download
To use Willar Programmer (often associated with WLPRO or SP200S hardware) on Windows 10, follow this guide to set up the software and drivers correctly. This software is primarily used for programming 8051 microcontrollers and EEPROMs. 1. Download and Software Installation
The software is typically distributed as a portable folder or a simple installer.
Willar Programmer (WLPRO): You can find a download link for the WLPRO V2.20 software at EEWorld or similar hardware documentation pages.
Installation: Unzip the folder to your local drive (e.g., C:\WLPRO) rather than running it from a temporary location to ensure settings are saved. 2. Driver Setup (Crucial for Windows 10)
The programmer usually relies on a USB-to-Serial chip like the CH340, PL2303, or CP2102.
Check Device Manager: Plug in your programmer. Right-click the Start button and select Device Manager. Legality: Intended for legitimate locksmith and repair use
Install Drivers: If you see a "USB2.0-Serial" or "Unknown Device" with a yellow warning:
For CH340 (common): Download drivers from ElectroDragon or the manufacturer's site.
For PL2303: Use the installer version v1.10.0 or later to ensure compatibility with Windows 10. 3. Configuring the COM Port
Willar software often only works with ports between COM1 and COM9.
In Device Manager, right-click your device > Properties > Port Settings > Advanced.
Change the COM Port Number to a single digit (e.g., COM3) if it is currently COM10 or higher. 4. Programming Steps
Open WLPRO: Run the executable. Look for a green "ONLINE" icon at the bottom of the window.
Select Device: Click the Device button and search for your specific chip (e.g., AT89S51@ISP or 24C02). Note: Using the ISP version for 89S series is often required to avoid ID errors. Load File: Click Load and select your .hex or .bin file.
Auto Program: Click Auto or Write to flash the chip. The software will typically perform an erase, write, and verify sequence automatically. 8051 & EEPROM Programmer Guide | PDF | Usb - Scribd
