---|---|---|---|---|---|
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. | |

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 DLPA300X. | |
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 Section 7.3.9 for more information. | |

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. |

NAME | NO. | ||||
CMP_OUT | A12 | I | 6 | Successive approximation ADC (analog-to-digital converter) comparator output (DLPC34xx Input). To implement, use a successive approximation ADC with a thermistor feeding one input of the external comparator and the DLPC34xx controller GPIO_10 (RC_CHARGE) pin driving the other side of the comparator. 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) | |
CMP_PWM | A15 | O | 1 | TI internal use. Leave this pin unconnected. | |
HOST_IRQ(2) | N8 | O | 9 | Host
interrupt (output) HOST_IRQ indicates when the DLPC34xx auto-initialization is in progress and most importantly when it completes. This pin is tri-stated during reset. An external pullup must be included on this signal. |
|
IIC0_SCL(4) | N10 | I/O | 7 | I2C slave (port 0) SCL (bidirectional, open-drain signal with input hysteresis): This pin requires an external pullup resistor. The slave I2C I/Os are 3.6-V tolerant (high-voltage-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 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. The slave I2C port is the control port of controller. The slave I2C I/O pins 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 does not typically satisfy the VIH specification of the slave I2C input buffers). | |
IIC1_SDA | R10 | I/O | 8 | TI internal use. TI recommends an external pullup resistor. | |

Enabled LED None Red Green Blue |
||||
LED_SEL_1 | B14 | O | 1 | The controller drives these signals low when RESETZ is asserted and the corresponding I/O power is supplied.

SPI0_CSZ0 | A14 | O | 13 | SPI port 0,
chip select 0 (active low output). This pin is typically connected
to the flash memory chip select. 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. |
