5.2 Jumpers and test pins
The TMC603 evaluation board is equipped with the following jumpers and test pins:
Jumper
Name
2
Function
BSL
X101
If this jumper is plugged, the Bootstrap Loader Mode (BSL) is enabled.
The main purpose of BSL Mode is to allow programming/erasing of the
Flash and XRAM by using the Infineon USB-2-CAN interface. The default
option is to unplug this jumper.
Attention: If you misuse the BSL mode the TMC603 evaluation board
firmware and bootloader will erase.
+5V OUT
X111
The microcontroller and its peripherals needs 5V power supply. This
jumper allows to select the 5V power source. You have two options:
1. Integrated 5V linear regulator of the TMC603 (40 mA cont.)
(jumper plugged in pin 2 and pin 3)
2. External voltage regulator (IC104)
(jumper plugged in pin 1 and pin 2)
The default option is the external voltage regulator.
SP_SUP
X216,
X217
The external capacitors on this pin controls the commutation spike
suppression time for hallFX™. Please refer the TMC603 data sheet for
more details.
Jumpers unplugged: C
SPSUP
= 2.2 nF (t
SPSUP
= 220µs)
X216 plugged only: C
SPSUP
= 2.2 nF + 2.2 nF = 4.4 nF
(t
SPSUP
= 440µs)
X217 plugged only: C
SPSUP
= 2.2 nF + 4.7 nF = 6.9 nF
(t
SPSUP
= 690µs)
X216 and X217 plugged: C
SPSUP
= 2.2 nF + 2.2 nF + 4.7 nF = 9.1 nF
(t
SPSUP
= 910µs)
