Programming Features
Production Programming Features
Elprotronic Inc. programming adapters provide a comprehensive set of advanced programming features designed to meet the requirements of modern manufacturing environments. In addition to high-speed device programming, they support production automation, device configuration, traceability, and secure programming workflows.
Gang Programming
Gang Programming enables multiple identical target devices to be programmed simultaneously using a single programming adapter. By performing parallel programming operations, manufacturers can significantly reduce programming time and increase overall production throughput.
Benefits include:
Lower production costs by reducing programming time.
Increased manufacturing capacity through parallel programming.
Improved production reliability with independent monitoring of each target.
Faster programming cycles compared to sequential programming.
Simplified operator workflow and reduced human error.
Support for up to 6 target MCUs programmed simultaneously (adapter dependent).
OTP, INFO, EEPROM & Fuse Programming
In addition to programming the main Flash memory, Elprotronic adapters support programming of device-specific non-volatile memory regions, including OTP (One-Time Programmable) memory, Information Memory, EEPROM, and configuration fuses, depending on the target MCU family.
Typical applications include:
Programming factory calibration and configuration data.
Device locking and unlocking.
Security and memory protection configuration.
Boot mode and startup configuration.
Programming user configuration registers and option bytes.
These features allow the complete device configuration to be performed during a single programming cycle.
Serialization
The Serialization feature automatically programs a unique identifier into each target device during production. Serialization data can include serial numbers, product identifiers, MAC addresses, manufacturing dates, or any application-specific identification data.
The programmer automatically increments the serialization value after each successful programming operation. During gang programming, every connected target receives its own unique serialization value independently.
Typical applications include:
Product traceability.
Manufacturing date and batch identification.
MAC address programming.
Unique device identification.
Asset tracking.
Standalone Programming
Standalone Programming allows the programmer to operate independently without requiring a host computer. After creating and downloading a standalone programming image, the programmer stores all required programming data and configuration in its internal memory.
Production operators can start programming simply by connecting the target device and pressing the GO button on the programmer.
Key advantages include:
No PC required during production.
Simple one-button operation.
Faster production setup.
Reduced risk of operator errors.
Ideal for manufacturing, service, and field programming.
Note: In Standalone Mode, each programmer operates independently and programs one target group according to its hardware capabilities and the stored standalone image.
External Flash Programming
Many modern MCUs use external non-volatile memories for firmware storage. Elprotronic programming adapters support programming of these external memories by utilizing the communication peripherals available on the target MCU, such as:
SPI
QSPI
OctoSPI
Other supported serial memory interfaces
During the programming process, the programmer downloads a small programming algorithm into the target MCU, which then programs the external Flash memory through its native peripheral interface.
No additional programming hardware or external connections are required beyond the standard JTAG or SWD connection, greatly simplifying hardware design and production fixtures.
Benefits include:
Programming external Flash without dedicated SPI programmers.
Faster production setup.
Simplified target hardware.
Support for large external memory devices.
Programming performed using the target MCU's native peripheral interface for maximum compatibility and reliability.
These advanced production features make Elprotronic programming adapters suitable for applications ranging from prototype development to fully automated, high-volume manufacturing environments requiring secure, traceable, and high-speed device programming.
