XStream-Iso Isolated Programmer

The Elprotronic XStream-Iso is a galvanically isolated MCU programmer with the same broad multi-vendor MCU coverage as the XStreamPro-Iso, 18+ silicon vendors including TI, STMicroelectronics, NXP, Nordic, Silicon Labs, Renesas, Microchip, Infineon, GigaDevice, and Maxim, in a streamlined PC-interactive configuration designed for engineering labs and mixed-MCU bench production. The 2.5 kV galvanic isolation protects both the programmer and the target board from ground loops and ESD events. The XStream-Iso supports a target voltage range of 1.65 V to 4.0 V and includes 20 uA sensitivity current monitoring for power profiling.

Specifications

Feature	Specification
MCU Vendors	18+ silicon vendors
Galvanic Isolation	2.5 kV between host and target
Target Voltage	1.65 V to 4.0 V
Interfaces	JTAG, SPI, TPI, PDI, UPDI, SWIM, SBW, BSL, SWD, SCI-BOOT, QSPI
Current Measurement	20 uA to 200 mA
Power Profiling	20 uA sensitivity current monitoring
Debug Support	CMSIS-DAP 2.0
Operation	PC-interactive (USB) only
Serialization	Auto-incrementing serial number injection
Verification	Checksum verification, read-back
Security	Device security lock programming
Software	FlashPro/GangPro (included)

CMSIS-DAP 2.0 debug support enables firmware development and debugging through the same hardware used for volume programming. The FlashPro/GangPro software platform provides unified control for firmware image management, programming sequence configuration, and serial number generation. The XStream-Iso operates in PC-interactive mode via USB only — it does not support standalone (PC-free) operation.

XStream-Iso vs XStreamPro-Iso

The XStream-Iso shares the same isolated architecture and MCU family support as the XStreamPro-Iso but targets use cases where standalone operation, extended storage, and ultra-low-current power profiling are not required. This makes it the cost-effective choice for engineering labs, bench production, and mixed-MCU development environments.
