Product details
Overview
DLPC3439ZEZ from Texas Instruments is a digital display controller IC designed specifically to drive the DLP4710 0.47-inch 1080p digital micromirror device (DMD), supporting up to 1080p resolution at 120 Hz frame rate, with embedded eDRAM, IntelliBright™ image processing, and sub-LVDS DMD interface for low-power operation in pico projector systems.
For engineers reviewing the DLPC3439ZEZ datasheet, DLPC3439ZEZ pinout, DLPC3439ZEZ application, or DLPC3439ZEZ equivalent, key selection considerations include parallel pixel interface timing (up to 155 MHz PCLK), CAIC illumination control, one-frame latency, I²C configuration, and compatibility with DLPA3000/DLPA3005 PMICs in compact DLP chipset designs.
Technical Context
The DLPC3439ZEZ implements a dedicated DMD interface stack comprising dual sub-LVDS high-speed write data lanes (16-bit A–H) plus HS clock differential pair and LS serial control interface, all synchronized to a programmable system oscillator. It integrates real-time pixel processing including 4:2:2 to 4:4:4 chroma interpolation, degamma, color space conversion, and local area brightness boost (LABB).
Its architecture supports two DLPC3439ZEZ controllers per DLP4710 DMD for enhanced throughput, uses embedded frame memory to achieve one-frame latency, and relies on external SPI flash (up to 128 Mb) for firmware storage while coordinating power sequencing with DLPA300x PMICs via PARKZ, RESETZ, and PROJ_ON signals.

FAQ
What is the primary function of the DLPC3439ZEZ in a DLP system?
The DLPC3439ZEZ serves as the core display controller IC that interfaces between a video source and the DLP4710 DMD, performing real-time pixel processing, DMD timing generation, sub-LVDS data serialization, and illumination control. It manages the complete signal chain from parallel RGB input to micromirror actuation, and DLPC3439ZEZ is required for any system using the DLP4710 1080p DMD in production designs.
Does the DLPC3439ZEZ require an external memory chip?
No - the DLPC3439ZEZ integrates embedded eDRAM sufficient for one full frame of 1080p data, eliminating the need for external SDRAM or DDR memory. This reduces PCB area, power consumption, and EMI, making DLPC3439ZEZ ideal for space-constrained pico projector modules where board real estate is at a premium.
Which power management ICs are compatible with the DLPC3439ZEZ?
The DLPC3439ZEZ is designed to pair exclusively with TI's DLPA3000 or DLPA3005 PMICs, which provide the precise bias voltages (VOFFSET, VBIAS, VRESET), LED current drivers, and power sequencing required by the DLP4710 DMD. Using DLPC3439ZEZ with non-TI PMICs is not supported and may result in DMD malfunction or reduced lifetime.
Can the DLPC3439ZEZ support 3D display functionality?
Yes - the DLPC3439ZEZ includes a dedicated 3DR input pin (N6) that accepts left/right frame identification signals, enabling active 3D projection when paired with compatible optics and firmware. The 3DR signal must transition mid-frame and be synchronized to VSYNC; this capability is confirmed in the DLPC3439ZEZ datasheet Section 5.2 and is fully implemented in production firmware.
What is the role of the PARKZ pin on the DLPC3439ZEZ?
The PARKZ pin (C13) is an active-low hardware signal that triggers immediate DMD mirror parking during power loss events, protecting the DLP4710 from mechanical stress. It is typically driven by the DLPA300x PMIC's interrupt output and operates independently of firmware - ensuring DLPC3439ZEZ executes safe parking even if software hangs or power collapses unexpectedly.
