DLPC3479CZEZ 概述
A DLP controller (Digital Light Projection controller) is a mixed-signal ASIC that orchestrates illumination timing, micromirror bit-planes, video processing, and host command interface for a DLP digital micromirror device (DMD). DLP controllers sit at the apex of the DLP chipset hierarchy (DLP controller -> DMD driver -> DMD -> optical engine -> display system), and are required to bring up, sequence, and continuously refresh the MEMS micromirror array while maintaining pixel-level color and brightness accuracy across frame rates.
Key features include support for the DLP4710LC 0.47-inch 1080p DMD, an integrated ARM Cortex host-side interface, integrated illumination driver interface, and high-speed DMD data path with deterministic latency. The device supports video display and light steering modes commonly used in industrial projection, 3D printing, 3D machine vision, and spectroscopy, while the 201-ball NFBGA provides the routing density required for the parallel DMD data bus at full HD resolution.
The DLPC3479 uses a programmable microcontroller subsystem to manage DMD load, micromirror reset sequences, LED/laser light source timing, and host command protocol over I2C or SPI. The 2xDLPC3479 dual-controller topology (referenced in the TI datasheet) supports higher resolution or higher brightness configurations by pairing two controllers with a single DMD, enabling synchronized bit-plane generation for light control applications such as structured light, mask-less lithography, and exposure systems.
Typical applications include 1080p portable projectors, industrial inspection cameras, structured-light 3D scanners, 3D printers, head-up displays, and medical imaging systems. The DLP4710LC chipset is also widely used in AR glasses, near-eye displays, and head-mounted displays where the small 0.47-inch panel format and DLP's high fill factor enable compact optical engines.
When designing with this device, ensure the PCB layout follows the TI NFBGA-201 escape pattern and that the DMD high-speed data bus is length-matched per the DLPC3479 datasheet guidelines. The DLPC3479 must be paired with the DLP4710LC DMD; it is not a generic DLP controller and cannot be substituted with DLPC34xx controllers intended for other DMDs without re-validating the full chipset configuration and firmware load.

典型应用
DLPC3479CZEZ 适用于 6 应用s: 1080p Portable Projector, Industrial 3D Machine Vision / Structured Light, AR / VR Near-Eye Display, 3D Printing / Additive Manufacturing, Medical Imaging / Endoscopy, Automotive Head-Up Display (HUD).
1080p Portable Projector
The DLPC3479CZEZ drives the DLP4710LC 0.47-inch 1080p DMD to produce a full-HD image in compact portable projectors and pico-projectors. Its NFBGA-201 footprint fits the small mainboards typical of <1 L projection engines, and the integrated LED/laser illumination timing interface removes the need for an external light-source sequencer. The 1080p resolution matches mainstream consumer and enterprise projection content without scaling artifacts. Compared with lower-resolution DLPC343x controllers, the DLPC3479 enables native 1920x1080 bit-plane generation, eliminating the resolution-conversion latency that bottlenecks pico-projector frame rates. Pair it with a DLPA3000/DLPA3005 LED driver to complete the chipset.
推荐
Industrial 3D Machine Vision / Structured Light
In structured-light 3D scanners and machine-vision cameras, the DLPC3479CZEZ steers the DLP4710LC DMD to project pre-distorted patterns onto objects, while a synchronized camera captures the deformation for depth reconstruction. The DLPC3479's deterministic DMD load timing is critical for high-speed pattern projection where sub-frame latency would corrupt the 3D point cloud. The 2xDLPC3479 dual-controller topology supported by TI doubles the achievable pattern rate for in-line factory inspection at conveyor speeds >1 m/s. The -30C to +85C industrial temperature range supports factory-floor deployments without additional thermal management. Pair with a global-shutter image sensor for full structured-light capture.
推荐
AR / VR Near-Eye Display
The DLPC3479CZEZ paired with the DLP4710LC DMD forms the smallest 1080p DLP optical engine available, making it suitable for near-eye AR glasses and head-mounted displays. DLP's high fill factor (>90%) and fast micromirror response produce sharp, low-latency imagery at the eye pupil - critical for VR/AR comfort and motion-to-photon latency targets under 20 ms. The DLPC3479's integrated host-side command interface simplifies the bridge from the application processor to the optical engine. The 13 mm x 13 mm NFBGA footprint supports slim temple-mounted electronics. Use with a TI DLPA3000 LED driver for synchronized illumination and eye-safety PWM control.
推荐
3D Printing / Additive Manufacturing
In DLP-based 3D printers and additive manufacturing systems, the DLPC3479CZEZ controls the DLP4710LC DMD to project UV-patterned cure images onto photopolymer resin, building parts layer by layer. The 1920x1080 resolution translates to XY pixel pitches as small as 35 um, delivering fine feature detail suitable for dental, jewelry, and engineering prototyping. The DLPC3479's synchronized LED/UV illumination control matches cure exposure dose to print layer time, which is essential for repeatable mechanical properties. The dual-controller 2xDLPC3479 mode supports larger build areas by tiling the DMD exposure. Pair with a UV-LED driver and motion-control FPGA.
推荐
Medical Imaging / Endoscopy
The DLPC3479CZEZ combined with the DLP4710LC DMD enables compact high-resolution projection modules used in medical imaging carts, surgical displays, and endoscopy reference systems. The wide operating temperature range (-30C to +85C) supports clinical and OR environments without additional thermal conditioning. The deterministic DMD timing ensures that reference patterns used in calibration and quantitative imaging are pixel-accurate across the lifetime of the device. For OEM medical integrators, the DLPC3479 chipset's long-term availability and TI's commitment to industrial-grade supply reduce regulatory re-submission risk. Pair with a TI medical-grade SoC for full IEC 60601-1 platform compliance.
推荐
Automotive Head-Up Display (HUD)
The DLPC3479CZEZ and DLP4710LC chipset is one of the imaging options considered for next-generation automotive head-up displays, where DLP's high brightness, wide color gamut, and resistance to thermal Solar Loading outperform LCD alternatives. The DLPC3479's programmable bit-plane sequencing enables dynamic resolution adjustment as vehicle speed and viewing distance change. TI's automotive-grade DLP variants target the same chipset; the standard DLPC3479CZEZ is qualified for industrial-temperature environments and can serve pre-production and aftermarket HUD modules. Pair with a TI DLPA200/DLPA300 automotive LED driver for sunlight-readable HUD luminance.

设计说明
The DLPC3479CZEZ ships in a 201-ball NFBGA (ZEZ) with 0.8 mm ball pitch. Follow the TI reference design PCB stack-up - a 4- or 6-layer board with a continuous ground plane under the BGA is required for signal integrity on the high-speed DMD data bus. Length-match the DMD LVDS pairs within the timing skew specified in the DLPC3479 datasheet; typical skew budget is sub-50 ps. Use micro-via-in-pad if your CM is qualified for it, otherwise dog-bone fanout is acceptable.
Estimated: at typical projector operating load with simultaneous DMD refresh and LED PWM control, the DLPC3479CZEZ dissipates approximately 1.5-2.5 W. The NFBGA-201 thermal resistance is approximately 25-30 C/W (theta_JA) on a 4-layer JEDEC test board, yielding a 50-75 C junction temperature rise above ambient. For sealed projection engines, derate ambient to <=70 C to keep Tj below 105 C. Provide thermal vias under the BGA and copper pours on inner layers to conduct heat away.
Do not attempt to substitute a DLPC343x-family controller (e.g., DLPC3430, DLPC3438) for the DLPC3479 - each DLPC chip targets a specific DMD and the firmware load is not interchangeable. Mixing controllers and DMDs from different DLP families results in no display output and possible DMD damage from incorrect reset sequencing. Always download the firmware image matched to the exact DMD PN from the TI DLPC3479 product page. Also ensure the DLPA LED driver is powered up before the DMD reset is deasserted, otherwise the DMD enters an undefined state.
Route the DMD high-speed data bus on the top layer directly under the BGA escape with no vias on the data lines themselves; place ground-return vias adjacent to each signal via to maintain controlled impedance. The I2C and SPI host interface lines should be pulled up to 1.8 V or 3.3 V per the DLPC3479 datasheet, with pull-up resistors placed close to the controller, not at the host. Keep analog supply pins (if exposed) bypassed with 100 nF X7R capacitors placed within 2 mm of each supply ball.
