What is IC programming?

Programmable ICs ship blank. We load firmware, configuration data, serial IDs, and encryption keys so microcontrollers, FPGAs, CPLDs, and memories wake up ready to perform.

Because we pair programming with PCB manufacturing and PCBA assembly, every lot follows the same travelers, inspections, and documentation as the rest of your build.

Why programming is essential

Initialization, boot code, interface settings, and feature unlocks all live inside programmable silicon. Reliable programming ensures functionality, enables rapid updates, protects IP, and lets a single stock IC cover many SKUs.

We manage bootloaders, configuration words, field updates, and end-of-line flashing so your hardware meets requirements before shipment.

Devices, methods, and interfaces

IC families we cover

Microcontrollers

ARM Cortex, AVR, PIC, STM32, and custom MCUs with firmware, bootloaders, and configuration words.

FPGAs & CPLDs

Bitstreams for Xilinx, Intel/Altera, Lattice, and complex programmable logic devices.

Flash & EEPROM

Data storage devices, parameter memories, and secure elements that need verified writes.

Programming methods

In-circuit (ISP)

Program on populated PCBAs for debugging, field service, and late-stage customization.

Offline & gang

High-speed pre-programming with gang programmers and automated handlers for mass production.

Interface coverage

JTAG, SPI, I2C, UART, SWD, and direct ISP bootloaders with fixtures tuned to your design.

Programmer types & automation

From desktop fixtures for R&D to automated handlers in production, we match tooling to your throughput targets.

Field programmers keep deployed equipment up to date, while in-system programmers tie directly into your test points without device removal.

Programming workflow

1
File intake
Receive HEX, JEDEC, SVF/STAPL, BIT, BIX, IEEE 1532, or custom binaries with version control.
2
Fixture + interface setup
Configure sockets, pogo fixtures, JTAG/SWD probes, or ISP harnesses per device.
3
Programming & verification
Load code, read-back verify, checksum, and apply fuse/security settings.
4
Labeling & traceability
Apply batch IDs, date codes, and traveler links tying firmware to hardware lots.
5
Integration
Return devices for SMT placement or reinstall on PCBAs with documented pass/fail results.

Key programmer specifications

Selecting the right programmer means balancing device coverage, throughput, and software integration.

Supported ICs: Ensure compatibility across MCUs, FPGAs, EEPROMs, and other devices.
Interfaces: Confirm JTAG, SPI, I2C, UART, SWD, and any direct-ISP options are available.
Programming throughput: Match cycle times to prototype, pilot, or mass-production needs.
File format support: Verify HEX, JEDEC, BIT, SVF/STAPL, BIX, IEEE 1532, and custom binaries are accepted.
Additional functions: Look for features like in-circuit debug, memory verify, and read/write protection.
Software compatibility: User-friendly GUIs, CLI automation, and API hooks streamline operations.
