Configuration
J1: Target reset configuration
Jumper J1 connects the Emulation Adapter reset line and the user target board reset line and is populated by default.
Emulation Adapter features a Reset push button (SW1).
If having problems establishing the initial debug session with the Emulation Adapter, remove J1 and try again.
J2 and J3: Clock source configuration
Jumpers J2 and J3 select clock source for the emulation device.
Position 1-2 (default position) selects the crystal circuit oscillator on the target. Position 2-3 selects an external clock source (Q1 socket on the Emulation Adapter). |
|
The Emulation Adapter may not operate when target board’s crystal circuit is used as the clock source. TIP: The crystal should be as close as possible to the microcontroller. The crystal on the target board might not oscillate in conjunction with the Emulation Adapter when the clock lines (TP21_2, TP21_3) between the crystal and the emulation device on the Emulation Adapter become too long, thus affecting the impedance of the crystal circuit. |
|
Separately packed 20 MHz crystal can be used as a 20 MHz external clock (XOSC) source to the emulation device. If a different clock frequency is required, insert appropriate crystal into the Q1 socket and replace C7 (default 10pF populated) and C8 (default 10pF populated) accordingly. Crystal socket Q1 is by default not populated (NP). |
Crystal socket Q1 schematics below:
J4 and J5: GND connection points
In case a good ground connection is required, connection points bridge J4 and pin J5 provide easy access to the Emulation Adapter's GND potential.
J6 and J7: VFLEX and VAREF
VFLEX - If the target’s VFLEX pin isn’t exposed, bridge the jumper J6 to connect VEXT from the target to power VFLEX.
|
Setting the jumper when emulating the BGA device may prevent establishing a debug connection or, in the worst case, can damage the Target board. |
VAREF - If the target’s VAREF2 pin isn’t exposed, bridge the jumper J7 to connect VAREF1 from the target to power VAREF2
|
Setting the jumper if VAREF2 is present on the device may prevent establishing a debug connection or, in the worst case, can damage the Target board. |
P2: Power supply configuration
Power supply of the Emulation Adapter is configured via the unshrouded 26-pin 2.54 mm header (P2).

P2 Signal description
By default, all jumpers are set to connect user target power supply to the microcontroller residing on the Emulation Adapter. Only pins 1-2, 3-4, 5-6, 7-8, 9-10 and 11-12 must be bridged, but for the convenience and ease of use, all jumpers are set, except for pins 25-26.
Pin 26 is the polarizer key preventing incorrect connection of the IEA-PS Power converter, when being plugged in.
If a different power source is used (e.g., a Standalone operation), remove all jumpers and apply 3V3 or 5V to:
•VEXT (pin 2), •VDDM (pin 4), •VAREF1 (pin 6), |
•VAREF2 (pin 8), •VEVRSB (pin 10), •VFLEX (pin 12). |
Enclosed Power supply package (Power converter and Power adapter) simply plugs into the P2 header row, providing the necessary power supply for Emulation Adapter operation. LED1 indicates if power is supplied to the Emulation Adapter.
Refer to the microcontroller documentation for more details about power voltage designations.

Standalone operation
Infineon TC377TE Emulation Adapter is delivered with all components required for a Standalone operation.
Power supply
Use the enclosed IEA-PS Emulation Adapter Power converter and adapter.
A Power supply package, which is delivered with the Emulation Adapter, is required when:
•The Emulation Adapter is used as a standalone device .
•The target board doesn’t provide an accurate supply voltage.
•The target board doesn’t provide sufficient current for the Emulation Adapter operation.
The Power converter can supply either 3.3 V or 5 V. The array of jumpers J0–J9 selects 3.3 V or 5 V voltage on the P3 connector, which connects to the Emulation Adapter.

P3 connector and J0–J9 jumper correlation table
For example, when J2 is in the 3V3 position, it supplies 3.3 V to pin 6 of the P3 connector. When J2 is in the 5V position, it supplies 5 V to pin 6 of the P3 connector pin.
|
Be careful not to supply 5 V to the microcontroller power supply pin, which has declared a maximum voltage 3.3 V! Refer to the microcontroller documentation for detailed information on power supply. |

Clock source
If the target’s crystal circuit microcontroller oscillator (if available) is not an adequate clock source, insert appropriate crystal into the Q1 socket, replace the default 10pF C7 and C8 capacitors when necessary and place jumpers J2 and J3 in 2-3 position.
