1 Notice

1.1 Power supply range: DC +4.0V ~ DC +5.0V

‘TMS320F28335 Value Module’ is powered by 2P molex connector (① - Red : VIN / Black : GND)

or by CN9100 pin header (② - #19 pin : VIN / #20 pin : GND). It causes damage to module if you

supply module with voltage which is out of specification.

1.2 Power supply methods

Case ②

Power supply to #19, #20 pins

of CN9100 pin header.

VIN GND

Caution ! You should use only one of power supply methods.

(Case ① or Case ②)

Case ①

Power supply to Molex connector.

VIN GND




1.3 ESD Caution

This product is very sensitive to static electricity.

Please handle in an environment devoid of static

electricity as much as possible.

1.4 CN9100 pin header’s #1 pin (A3.3V)

CN9100’s A3.3V(#1pin) is designed for internal testing.

You can’t use it for power supply of external system or circuit.




2 JTAG Interface

2.1 JTAG Interface Circuit

[P-2-1] – JTAG Interface

2.2 Option resistor for JTAG interface (PD pin)

TMS320F28335 Value Module’s JTAG interface is designed to select voltage into PD pin (3.3V or

Vin). Depending on the PD pin voltage specification of emulator you’re using, please change the

location of the 0Ω resistor. (Factory setting is ‘Vin’.)

[P-2-2] – Location of option resistors




3 Boot-mode Selection

3.1 Boot-modes of TMS320F28335

[T-3-1] – Boot-mode Selection

Factory setting is ‘Mode 4 – jump to SARAM’.




3.2 Boot-mode Selection Circuit

[P-3-1] – Boot-mode Selection Circuit

[P-3-2] – Location of Resistors for Boot-mode Selection

Factory setting:

Jump to SARAM

(Use 47kΩ resistors)
