Product details
Overview
AT91SAM-ICE from Atmel is a USB-powered JTAG/SWD in-circuit emulator for debugging AT91 ARM7TDMI-based microcontrollers. It supports 1.2V–3.3V target voltage, delivers up to 12MHz JTAG clock speed with adaptive clocking, and integrates seamlessly with IAR Embedded Workbench and RDI-compliant debuggers for embedded firmware development.
For engineers reviewing the AT91SAM-ICE datasheet, AT91SAM-ICE pinout, AT91SAM-ICE application, or AT91SAM-ICE equivalent, this page provides verified hardware interface details, multi-core scan chain support, SWO trace capability, and real-world setup guidance for Windows host systems and AT91 target boards.
Technical Context
SAM-ICE implements ARM-compliant JTAG (20-pin) and Serial Wire Debug (SWD) interfaces, sharing pins 7 (SWDIO/TMS) and 9 (SWCLK/TCK). It uses adaptive clocking via RTCK feedback to synchronize with target timing margins and supports up to eight devices in a single JTAG scan chain - including multiple AT91 CPU cores - with per-core selection handled by host debugger configuration.
The unit operates without external power, drawing <50mA from USB 2.0 full-speed interface, and includes built-in utilities: JLink.exe CLI tool, J-Mem memory viewer for runtime RAM/SFR editing, and SAM-ICE TCP/IP Server for remote debugging over LAN - all shipped free with no license required.

FAQ
What ARM cores does the AT91SAM-ICE support?
The AT91SAM-ICE supports all Atmel AT91 ARM7TDMI-based microcontrollers, including SAM7 series devices. It does not support Cortex-M or Cortex-A processors. The AT91SAM-ICE user guide explicitly states compatibility with "any Atmel AT91 core" and confirms Thumb mode execution support - a defining feature of ARM7TDMI architecture. No documentation extends support beyond the AT91 family.
Does AT91SAM-ICE support Serial Wire Output (SWO) trace?
Yes, AT91SAM-ICE supports SWO via pin 13 on its 20-pin JTAG connector, enabling Serial Wire Viewer (SWV) functionality for ITM-based printf-style debug output and event tracing. SWO is optional and not required for basic SWD communication; it requires target-side ITM configuration and is used alongside SWDIO/SWCLK for low-cost runtime visibility into ARM7TDMI-based firmware.
Can AT91SAM-ICE debug multiple AT91 devices on one JTAG scan chain?
Yes, AT91SAM-ICE supports up to eight devices in a single JTAG scan chain, including multiple AT91 CPU cores. Each core is selected individually by the host debugger (e.g., IAR C-SPY or Atmel Studio) through scan chain position configuration - no hardware modification is needed. This capability is documented in Section 2.1.2 and Figure 2-2 of the official user guide.
Is AT91SAM-ICE compatible with modern Windows versions like Windows 10 or 11?
Yes, AT91SAM-ICE is compatible with Windows 2000 and newer, including Windows 10 and 11, when using the official Segger-provided USB driver. The device enumerates as a J-Link-compatible interface, and JLink.exe reports correct firmware build date and serial number on these OS versions - confirmed in Section 4.1.1 of the user guide and field-deployed validation.
What software ships with AT91SAM-ICE and is it license-free?
AT91SAM-ICE ships with JLink.exe (CLI tool), J-Mem memory viewer, SAM-ICE TCP/IP Server, SAM-ICE ARM Flash DLL, and RDI support - all provided free of charge with no license required. These tools are downloadable from segger.com and included on the original AT91 DVD-ROM, as listed in Table 5-1 and Section 5.2 of the user guide.
