SB-USB2 and USB-EMU JTAG/OnCE Emulators

SB-USB2: High Performance JTAG/OnCE Emulator

The SB-USB2 emulator enables efficient and productive embedded software debugging for

Freescale Symphony DSPs. Both compact and portable, the SB-USB2 utilizes the JTAG

and/or On-Chip Emulation (OnCE) protocols. This versatile probe supports several connector

configurations: two JTAG connections; two OnCE connections; or an individual JTAG and OnCE

connection. In addition, the SB-USB2 supplies benchmark timers and an 18-channel, 40 MHz

logic analyzer.

SB-USB2 Key Features

• USB port powered

• JTAG TAP debug support

• JTAG boundary scan support

The SB-USB2 probe is powered by the USB connection, making it ideal for notebook

computers or lab environments. In addition, it can detect whether or not the device has power,

and can also supply up to 200 mA of power to the target device. The emulator provides

benchmark timers: for the OnCE connection, the negative pulse coming over DSO stops the

timer; for the JTAG connection, the -DE signal stops the timer.

USB-EMU: JTAG/OnCE Emulator

The USB-EMU emulator enables efficient and productive embedded software debugging for

Freescale Symphony DSPs. Both compact and portable, it uses the JTAG and OnCE protocols,

promoting debug flexibility and convenience.

When used with Domain Technologies’ debugger, the USB-EMU provides access to the

JTAG device’s boundary scan functionality (BSDL file required). Boundary scan operations

enable non-intrusive monitoring of the target device pins, even while the target device is

executing its own application code. The USB-EMU emulator can program external flash

memory devices also.

USB-EMU Key Features

• JTAG TAP debug support for standard

JTAG test access port devices

The USB-EMU probe is powered by the USB connection, making it ideal for use by notebook

computers or lab environments. The USB-EMU can detect whether or not the device has

power; in addition, it can also supply up to 300mA of power to the device.

Freescale and Domain Technologies

Domain’s products promote cost reduction through time to market savings. BoxView IDE is an

Eclipse based, open, industry supported, extensible software development environment which

provides a compiler, linker, source code project manager, editors, and Domain’s DSP target debugger.

The USB-EMU and SBUSB2, our JTAG/OnCE emulators, offer efficient and convenient emulation for

the Freescale Symphony DSP family.
