Flasher PPC

Flash Programmer for PowerPC cores

Flasher PPC is a programming tool for PowerPC based microcontrollers with on-chip or external flash memory. Flasher PPC is designed for programming flash targets with the J-Flash software or stand-alone. It connects via Ethernet, USB or RS232 interface to a PC, running Microsoft Windows 2000 or later (for a list of supported versions, please refer to the specifications below). 
Flasher PPC itself has a built-in 20-pin JTAG connector but is shipped with an 14-pin adapter for PowerPC devices. 


  • Stand-alone JTAG programmer (Once set up, Flasher can be controlled without the use of PC program)
  • Support for PowerPC cores. For a complete list, please click here
  • Supports programming of internal and external flash memory
  • Free software updates1, 2 years of support
  • 64 MB memory for storage of target program
  • Host interfaces: Ethernet, USB, RS232
  • Serial in target programming supported
  • Data files can be updated via Ethernet/USB using J-Flash, via RS232 or via the mass storage functionality of Flasher PPC
  • Target interface: JTAG
  • No power supply required, powered through USB
  • Programming speed up to 138 KB/second depending on target hardware
  • ASCII command interface to control Flasher without the use of PC program
  • Authorized Flashing allows to limit the number of flash programming cycles and to protect the Flasher against non-authorized access in case of external production

1As a legitimate owner of a SEGGER Flasher, you can always download the latest software free of charge. Though not planned and not likely, we reserve the right to change this policy. Note that older models may not be supported by newer versions of the software. Typically, we support older models with new software at least 3 years after end of life.

JTAG interface connection (14-pin)

Pin Signal Type Description
1 TDI Output JTAG clock signal to target CPU. It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TCK on target CPU.
3 TDO Input JTAG data output from target CPU. Typically connected to TDO on target CPU.
5 TCK Output JTAG clock signal to target CPU. It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TCK on target CPU.
7 --- NC This pin is not connected to Flasher PPC.
8 --- NC This pin is not connected to Flasher PPC.
9 nRES I/O Target CPU reset signal. Typically connected to the RESET pin of the target CPU, which is typically called "nRST", "nRESET" or "RESET".
10 TMS Output JTAG mode set input of target CPU. This pin should be pulled up on the target. Typically connected to TMS on target CPU.
11 VDDE7 Input This is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor.
13 nRDY Input Nexus ready output. Indicates to the development tools that the data is ready to be read from or written to the Nexus read/write access registers.
14 JCOMP Output JTAG TAP Controller Enable / JTAG Compliancy (JCOMP). JCOMP is used to enable the TAP controller for communication to the JTAG state machine for boundary scan and for debug access. This pin is set to HIGH by Flasher PPC (in order to enable the JTAG TAP controller on the target device).


  • All pins marked NC are not connected to Flasher PPC. Any signal can be applied here; Flasher PPC will simply ignore such a signal.
  • Pins 2, 4, 6, 12 are GND pins connected to GND in Flasher PPC. They should also be connected to GND in the target system.
