Flash Programmer Model TFP2 User’s Manual

1 GETTING STARTED
1.1 GENERAL
The TFP2 Flash Programmer, Model TFP2 provides a stand-alone, FLASH memory programming tool for
Teridian Semiconductor’s embedded controllers. The TFP2 facilitates FLASH programming in a
manufacturing production environment requiring minimum ancillary equipment. Once the TFP2 has been
initialized with the target’s program code, the target’s FLASH memory can be programmed either
manually via operator push button, or controlled via a factory automation computer (ATE).
The target’s program code is stored in a standard 32-pin PLCC 256 KB x 8 Flash PROM (EEPROM). A
RS-232 interface is provided for connection to a PC allowing for downloading of the target’s program
code to the TFP2’s internal EEPROM. This downloading utility along with target programming and
additional status information is provided via a simple text based user interface.
The TFP2 supports target flash memory sizes of: 8KB, 16KB, 32KB, 64KB, 128KB, and 256KB.
Once the TFP2’s internal EEPROM is programmed, the PC may be removed for standalone operation.
Standalone operation only performs the target FLASH memory programming. Once programmed, the
target’s FLASH memory contents are verified and a PASS or FAIL indication is reported. The TFP2 front
panel incorporates two status LEDs. These status indications are also provided at the ATE connector
and displayed by the PC User Interface.
Two target connectors are provided to facilitate custom target connections. The standard ADM-51 ribbon
cable connector is provided along with a discrete wire connector. The discrete wire connector
accommodates low cost, custom cable harnesses. These two cable connector interfaces are hardwired
together and are not two separate interfaces.
1.2 SAFETY AND ESD NOTES
Standard ESD handling precautions should be employed whenever handling electronic equipment. The
TFP2 Flash Programmer utilizes ESD protection devices on its cable interfaces. Potential equipment
damage and/or malfunction is possible if work surface grounding procedures are not incorporated.
The TFP2 ESD protection devices do not protect the target’s hardware. Correct
handling procedures and proper work area grounding minimizes damage to all
equipment!
