1 GETTING STARTED
1.1 GENERAL
The TSC Flash Programmer, Model TFP2 provides a standalone, 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 PROM internal to the TFP2. A board socket
is provided for accommodating externally programmed ROM’s. The TFP2 is shipped with a 256 KB x 8
Flash PROM (EEPROM) installed in the socket for internal programming. A RS232 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
TSC 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!

2 TARGET CODE INITIALIZATION
Before the target’s FLASH memory can be programmed, the target code must be transferred to the TFP2 for internal
storage. First configure the TFP2 for the proper memory size of the target’s code. Rotate the internal Memory Size
rotary switch to the appropriate position. There is a black arrow on top of the rotary switch shaft denoting the switch
position. Only 6 of the 8 switch positions are used. The other 2 positions are not used. A blinking red LED after
applying power to the TFP2 indicates one of these unused positions is currently selected. Rotate the Memory Size
Switch to a proper setting and re-apply power to the TFP2 to update the Memory Size setting.

Figure 2-2 shows the basic RS232 connection of the TFP2 to a PC. Invoking a terminal emulator program such as
Microsoft’s Windows 2000HyperTerminal, displays a simple text based user interface for controlling the TFP2.
Refer to Chapter 4, PC User Interface for instructions on using the user interface.

2.1 POWER SUPPLY CONNECTION
The TFP2 is supplied with a universal AC/DC wall transformer. Alternatively, the TFP2 can be powered by another
external power supply. The TFP2’s power connector requires a 2.5 mm (inner diameter) power plug. The center
conductor is the +VDC and the outer conductor is Ground. External power supply voltage range is +5VDC +/- 10%
regulated. Maximum required power supply current is 200 mA.
NOTE: The TFP2 does not supply power at the Target-LS and Target-HS connectors. Power must be
supplied to the target board separately. The TFP2 must be powered first before connecting the target board
to the TFP2.

3 TARGET FLASH MEMORY PROGRAMMING
The TFP2 Flash Programmer connects to the target board via one of two connectors:
1) The Target-LS connector provides connection using discrete wires.
Only use this interface for TCLK frequencies of 10 MHz or less.
Figure 3-1: Target-LS Connection
2) The Target-HS connector utilizes the ADM-1 ribbon cable connector.
Must use this interface for TCLK frequencies of 10 MHz or faster.

3.1 STANDALONE PROGRAMMING
With the TFP2’s internal EEPROM initialized with the target’s code as described in Chapter 2, and the target board
connected to the TFP2 via the Target-LS connector or the Target-HS connector, programming of the target’s flash
memory may begin.
Figure 3-5: Standalone Configuration (shown with Target-LS cable for example)
When power is applied at the DC IN connector, the yellow power indicator LED is illuminated. Programming of the
target FLASH Memory begins upon pressing the “Program” button. A momentary push button press of 100 msec,
not to exceed 1 second is required to commence programming. Mass erase of the target’s FLASH memory is
performed first before programming of the code begins. The green Programming/Pass LED blinks while
programming is in progress. Upon completion of programming, the target’s FLASH Memory contents are read back
for verification. The green Programming/Pass LED stops blinking and turns on solid if the target’s FLASH Memory
contents are verified as good. If verification fails, the red Fail LED turns on solid. If the TFP2 cannot communicate
with the target, the red Fail LED turns on immediately. Communications failure may result from no target power, bad
cable or faulty target board. No target FLASH Memory programming will have occurred when communication has not
been established. Either LED indication is cleared upon re-pressing the Program button.
NOTE: The TFP2 must be powered first before connecting the target board to the TFP2.
NOTE: The target’s watchdog timer must be enabled (V1 pin not connected to V3P3) and
the target’s ICE_E pin (if available on target device) must be connected to the
appropriate TFP2 connector pin for target flash re-programming if the target’s
security bit is set.

3.2 PC USER INTERFACE PROGRAMMING
Alternatively, manual programming may be performed using the PC User Interface. The green and red LED
indicators function as described above. The operational status information is also duplicated on the PC’s screen.
Refer to Chapter 4 for instructions on using the PC User Interface.
Figure 3-6: PC User Interface Configuration (shown with Target-HS cable for example)
NOTE: The TFP2 must be powered first before connecting the target board to the TFP2.

3.3 ATE FACTORY AUTOMATION PROGRAMMING
Automated programming of the target’s FLASH Memory may be performed using the ATE connector. The interface
signals provided at the ATE connector allow a factory automation computer to commence programming and monitor
the status of the programming results. The ATE interface cannot download target code to the TFP2’s internal
EEPROM.
Figure 3-7: ATE Configuration (shown with Target-LS cable for example)
The TFP2 must be powered first before connecting the target board to the TFP2.
The ATE connector pin assignments are as follows:
ATE Pin Pin Function TFP2 I/O Description
1 RESETB Input Active LO reset to TFP2 processor.
2 Ground
3 PROGRAM
Input Active HI signal starts target FLASH Memory programming. A
minimum 200 ms pulse is required.
4 Ground
5 PROGRAM
ACTIVE
Output Active Hi signal indicates target FLASH Memory programming in
progress. De-assert PROGRAM upon PROGRAM ACTIVE going
high.
6 Ground
7 PASS
Output Active HI signal indicates target FLASH Memory verified to be correct.
PASS goes low when PROGRAM is re-asserted high. PASS toggles
Hi and LO during programming sequence.
8 Ground
9 FAIL
Output Active HI signal indicates target FLASH Memory failed verification.
FAIL goes low when PROGRAM is re-asserted high. FAIL toggles HI
and LO if the TFP2 cannot communicate with the target board.
