Pin Functions – Test Pins and General Control

PIN I/O TYPE(4) DESCRIPTION
NAME NO.
HWTEST_EN C10 I 6 Manufacturing test enable signal. Connect this signal directly to ground on the PCB for normal operation.
PARKZ C13 I 6 DMD fast park control (active low Input with a hysteresis buffer). This signal is used to quickly park the DMD when loss of power is imminent. The longest lifetime of the DMD may not be achieved with the fast park operation; therefore, this signal is intended to only be asserted when a normal park operation is unable to be completed. The PARKZ signal is typically provided from the DLPAxxxx interrupt output signal.
JTAGTCK P12 I 6 TI internal use. Leave this pin unconnected.
JTAGTDI P13 I 6 TI internal use. Leave this pin unconnected.
JTAGTDO1 N13(1) O 1 TI internal use. Leave this pin unconnected.
JTAGTDO2 N12(1) O 1 TI internal use. Leave this pin unconnected.
JTAGTMS1 M13 I 6 TI internal use. Leave this pin unconnected.
JTAGTMS2 N11 I 6 TI internal use. Leave this pin unconnected.
JTAGTRSTZ P11 I 6 TI internal use.
This pin must be tied to ground, through an external resistor for normal operation. Failure to tie this pin low during normal operation can cause start up and initialization problems.(2)
RESETZ C11 I 6 Power-on reset (active low input with a hysteresis buffer). Self-configuration starts when a low-to-high transition is detected on RESETZ. All controller power and clocks must be stable before this reset is de-asserted. No signals are in their active state while RESETZ is asserted. This pin is typically connected to the RESETZ pin of the DLPA200x or RESET_Z of the DLPA3000.
TSTPT_0 R12 I/O 1 Test pins (includes weak internal pulldown). Pins are tri-stated while RESETZ is asserted low. Sampled as an input test mode selection control approximately 1.5 µs after de-assertion of RESETZ, and then driven as outputs.(2)(3)

Normal use: reserved for test output. Leave open for normal use.
Note: An external pullup may put the DLPC34xx in a test mode. See Test Point Support for more information.
TSTPT_1 R13 I/O 1
TSTPT_2 R14 I/O 1
TSTPT_3 R15 I/O 1
TSTPT_4 P14 I/O 1
TSTPT_5 P15 I/O 1
TSTPT_6 N14 I/O 1
TSTPT_7 N15 I/O 1
If the application design does not require an external pullup, and there is no external logic that can overcome the weak internal pulldown resistor, then this I/O pin can be left open or unconnected for normal operation. If the application design does not require an external pullup, but there is external logic that might overcome the weak internal pulldown resistor, then an external pulldown is recommended to ensure a logic low.
External resistor must have a value of 8 kΩ or less to compensate for pins that provide internal pullup or pulldown resistors.
If the application design does not require an external pullup and there is no external logic that can overcome the weak internal pulldown, then the TSTPT I/O can be left open (unconnected) for normal operation. If operation does not call for an external pullup, but there is external logic that might overcome the weak internal pulldown resistor, then an external pulldown resistor is recommended to ensure a logic low.
See Table 2 for type definitions.

Pin Functions – DMD Reset and Bias Control

PIN I/O TYPE(1) DESCRIPTION
NAME NO.
DMD_DEN_ARSTZ B1 O 2 DMD driver enable (active high). DMD reset (active low). When corresponding I/O power is supplied, the controller drives this signal low after the DMD is parked and before power is removed from the DMD. If the 1.8-V power to the DLPC34xx is independent of the 1.8-V power to the DMD, then TI recommends including a weak, external pulldown resistor to hold the signal low in case DLPC34xx power is inactive while DMD power is applied.

It is recommended to use the DLPAxxxx to achieve this function. CMP_OUT must be pulled-down to ground if this function is not used. (hysteresis buffer)

External I2C pullups must be connected to a host supply with an equal or higher supply voltage, up to a maximum of 3.6 V (a lower pullup supply voltage does not typically satisfy the VIH specification of the slave I2C input buffers).
IIC1_SCL R11 I/O 8 TI internal use. TI recommends an external pullup resistor.
IIC0_SDA(4) N9 I/O 7 I2C slave (port 0) SDA. (bidirectional, open-drain signal with input hysteresis): This pin requires an external pullup resistor.

TI recommends an external pullup resistor to avoid floating inputs to the external SPI device during controller reset assertion.
SPI0_CSZ1 C12 O 13 SPI port 0, chip select 1 (active low output). This pin typically remains unused.
TI recommends an external pullup resistor to avoid floating inputs to the external SPI device during controller reset assertion.
SPI0_DIN B12 I 12 Synchronous serial port 0, receive data in. This pin is typically connected to the flash memory data out.
SPI0_DOUT B13 O 13 Synchronous serial port 0, transmit data out. This pin is typically connected to the flash memory data in.
External pullup resistor must be 8 kΩ or less.
For more information about usage, see Device Startup.
See Table 2 for type definitions.
When VCC_INTF is powered and VDD is not powered, the controller may drive the IIC0_xxx pins low which prevents communication on this I2C bus. Do not power up the VCC_INTF pin before powering up the VDD pin for any system that has additional slave devices on this bus.
