Pin Functions – Board Level Test, Debug, and Initialization

PIN I/O DESCRIPTION
NAME NUMBER
HWTEST_EN C10 I6 Manufacturing test enable signal. This signal should be connected directly to ground on the PCB for normal operation.
PARKZ C13 I6 DMD fast PARK control (active low input, hysteresis buffer). PARKZ must be set high to enable normal operation. PARKZ should be set high prior to releasing RESETZ (that is, prior to the low-to-high transition on the RESETZ input). PARKZ should be set low for a minimum of 32 µs before any power is removed from the DLPC3432 such that the fast DMD PARK operation can be completed. Note for PARKZ, fast PARK control should only be used when loss of power is about to happen and beyond the control of the host processor (for example, when the external power source has been disconnected or the battery has dropped below a minimum level). The longest lifetime of the DMD is not achieved with the fast PARK operation, but rather with a normal PARK operation. Because of this, PARKZ is typically used in conjunction with a normal PARK request control input through GPIO_08. The difference being that when the host sets PROJ_ON low, which connects to both GPIO_08 and the DLPA2000 PMIC chip, the DLPC3432 takes much longer than 32 µs to park the mirrors. The DLPA2000 holds on all power supplies and keeps RESETZ high until the longer mirror parking has completed. This longer mirror parking time, of up to 500 µs, ensures the longest DMD lifetime and reliability.
The DLPA2000 monitors power to the DLPC3432 and detects any imminent power loss condition and drives the PARKZ signal accordingly.
Reserved P12 I6 TI internal use. Should be left unconnected.
Reserved P13 I6 TI internal use. Should be left unconnected.
Reserved N13(1) O1 TI internal use. Should be left unconnected.

Reserved P11 I6 TI internal use.
This pin must be tied to ground, through an external resistor of up to 8 kΩ for normal operation. Failure to tie this pin low during normal operation will cause start-up and initialization problems.
RESETZ C11 I6 DLPC3432 power-on reset (active low input, hysteresis buffer). Self-configuration starts when a low-to-high transition is detected on RESETZ. All ASIC power and clocks must be stable before this reset is de-asserted. Note that the following signals will be tri-stated while RESETZ is asserted:
SPI0_CLK, SPI0_DOUT, SPI0_CSZ0,
SPI0_CSZ1, and GPIO(19:00)
External pullups or downs (as appropriate) should be added to all tri-stated output signals listed (including bidirectional signals to be configured as outputs) to avoid floating ASIC outputs during reset if connected to devices on the PCB that can malfunction. For SPI, at a minimum, any chip selects connected to the devices should have a pullup.
Unused bidirectional signals can be functionally configured as outputs to avoid floating ASIC inputs after RESETZ is set high.
The following signals are forced to a logic low state while RESETZ is asserted and corresponding I/O power is applied:
LED_SEL_0, LED_SEL_1 and DMD_DEN_ARSTZ
No signals will be in their active state while RESETZ is asserted.
Note that no I2C activity is permitted for a minimum of 500 ms after RESETZ (and PARKZ) are set high.
TSTPT_0 R12 B1 Test pin 0 (includes weak internal pulldown) – 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 an output.

Normal use: Reserved for test output. Should be left open for normal use.
Alternative use: none. External logic shall not unintentionally pull this pin high to avoid putting the DLPC3432 in a test mode.
TSTPT_7 N15 B1 Test pin 7 (Includes weak internal pulldown) – 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 an output.
Normal use: Reserved for test output. Should be left open for normal use.
If operation does not call for an external pullup and there is no external logic that might overcome the weak internal pulldown resistor, then this I/O can be left open or 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.
External pullup resistor must be 8 kΩ, or less, for pins with internal pullup or down resistors.
If operation does not call for an external pullup and there is no external logic that might overcome the weak internal pulldown resistor, 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.

PIN I/O DESCRIPTION
NAME NUMBER
DMD_DEN_ARSTZ B1 O2 DMD driver enable (active high) or DMD reset (active low). Assuming the corresponding I/O power is supplied, this signal will be driven low after the DMD is parked and before power is removed from the DMD. If the 1.8-V power to the DLPC3432 is independent of the 1.8-V power to the DMD, then TI recommends a weak, external pulldown resistor to hold the signal low in the event the DLPC3432 power is inactive while DMD power is applied.

NAME NUMBER
CMP_OUT A12 I6 Successive approximation ADC comparator output (DLPC3432 input). Assumes a successive approximation ADC is implemented with a WPC light sensor possibly with a thermistor feeding one input of an external comparator and the other side of the comparator is driven from the ASIC’s CMP_PWM pin. Should be pulled-down to ground if this function is not used (hysteresis buffer).

HOST_IRQ(2) N8 O9 Host interrupt (output)
HOST_IRQ indicates when the DLPC3432 auto-initialization is in progress and most importantly when it completes.
The DLPC3432 tri-states this output during reset and assumes that an external pullup is in place to drive this signal to its inactive state.
IIC0_SCL N10 B7 I2C slave (port 0) SCL (bidirectional, open-drain signal with input hysteresis): An external pullup is required. The slave I2C I/Os are 3.6-V tolerant (high-volt-input tolerant) and are powered by VCC_INTF (which can be 1.8, 2.5, or 3.3 V). 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 would not likely satisfy the VIH specification of the slave I2C input buffers).
Reserved R11 B8 TI internal use. TI recommends an external pullup resistor.
IIC0_SDA N9 B7 I2C slave (port 0) SDA. (bidirectional, open-drain signal with input hysteresis): An external pullup is required. The slave I2C port is the control port of ASIC. The slave I2C I/Os are 3.6-V tolerant (high-volt-input tolerant) and are powered by VCC_INTF (which can be 1.8, 2.5, or 3.3 V). 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 would not likely satisfy the VIH specification of the slave I2C input buffers).

  2. Optional GPIO. Should be configured as a logic zero GPIO output and left unconnected if not used (otherwise it will require an external pullup or pulldown to avoid a floating GPIO input).
GPIO signals must be configured through software for input, output, bidirectional, or open-drain. Some GPIO have one or more alternative use modes, which are also software configurable. The reset default for all GPIO is as an input signal. An external pullup is required for each signal configured as open-drain.
DLPC3432 general purpose I/O. These GPIO are software configurable.

Pin Functions – Clock and PLL Support

PIN I/O DESCRIPTION
NAME NUMBER
PLL_REFCLK_I H1 I11 Reference clock crystal input. If an external oscillator is used in place of a crystal, then this pin should be used as the oscillator input.
PLL_REFCLK_O J1 O5 Reference clock crystal return. If an external oscillator is used in place of a crystal, then this pin should be left unconnected (that is floating with no added capacitive load).
