(2) external pullup resistor must be 8 k , or less, for pins with internal pullup or down resistors. (3) 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 functions ? board level test, debug, and initialization pin i/o description name number hwtest_en c10 i 6 manufacturing test enable signal. this signal should be connected directly to ground on the pcb for normal operation. parkz c13 i 6 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 s 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 s 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 s, 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 i 6 ti internal use. should be left unconnected. reserved p13 i 6 ti internal use. should be left unconnected. reserved n13 (1) o 1 ti internal use. should be left unconnected. reserved n12 (1) o 1 ti internal use. should be left unconnected. reserved m13 i 6 ti internal use. should be left unconnected. reserved n11 i 6 ti internal use. should be left unconnected. reserved p11 i 6 ti internal use. this pin must be tied to ground, through an external resistor of up to 8 k for normal operation. failure to tie this pin low during normal operation will cause start-up and initialization problems. resetz c11 i 6 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 i 2 c activity is permitted for a minimum of 500 ms after resetz (and parkz) are set high. tstpt_0 r12 b 1 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 s after de-assertion of resetz, and then driven as an output. normal use: reserved for test output. should be left open for normal use. note: an external pullup should not be applied to this pin to avoid putting the dlpc3432 in a test mode. without external pullup (2) feeds tmsel(0) with external pullup (3) feeds tmsel(0)

(1) these are only the default output selections. software can reprogram the selection at any time. table 8. test mode selection scenario defined by tstpt(2:0) (1) tstpt(2:0) capture value no switching activity clock debug output x000 x010 tstpt(0) hi-z 60 mhz tstpt(1) hi-z 30 mhz tstpt(2) hi-z 0.7 to 22.5 mhz tstpt(3) hi-z high tstpt(4) hi-z low tstpt(5) hi-z high tstpt(6) hi-z high tstpt(7) hi-z 7.5 mhz 8.4.10 dmd interface considerations the sub-lvds high speed interface waveform quality and timing on the dlpc3432 asic is dependent on the total length of the interconnect system, the spacing between traces, the characteristic impedance, etch losses, and how well matched the lengths are across the interface. thus, ensuring a positive timing margin requires attention to many factors. as an example, the dmd interface system timing margin can be calculated as follows: setup margin = (dlpc3432 output setup) ? (dmd input setup) ? (pcb routing mismatch) ? (pcb si degradation) (1) hold-time margin = (dlpc3432 output hold) ? (dmd input hold) ? (pcb routing mismatch) ? (pcb si degradation) where pcb si degradation is signal integrity degradation due to pcb effects which include simultaneously switching output (sso) noise, cross-talk and inter-symbol interference (isi) noise. (2) the dlpc3432 i/o timing parameters as well as dmd i/o timing parameters can be found in their corresponding data sheets. similarly, pcb routing mismatch can be budgeted and met through controlled pcb routing. however, pcb si degradation is a more complicated adjustment. in an attempt to minimize the signal integrity analysis that would otherwise be required, the following pcb design guidelines are provided as a reference of an interconnect system that will satisfy both waveform quality and timing requirements (accounting for both pcb routing mismatch and pcb si degradation). variation from these recommendations may also work, but should be confirmed with pcb signal integrity analysis or lab measurements.
