Product details
Overview
DLPC3437CZEZ from Texas Instruments is a digital display controller IC designed to drive the DLP3310 0.33-inch 1080p digital micromirror device (DMD). It supports up to 1080p input resolution at 120 Hz frame rate, integrates embedded eDRAM for one-frame latency, and implements IntelliBright™ image processing including CAIC and LABB for adaptive illumination control.
For engineers reviewing the DLPC3437CZEZ datasheet, DLPC3437CZEZ pinout, DLPC3437CZEZ application, or DLPC3437CZEZ equivalent, key selection considerations include its NFBGA-201 package, dual FPD-Link/parallel pixel interface support up to 155 MHz, I²C configuration interface, and requirement for pairing with DLPA3000/DLPA3005 PMICs in DLP chipset implementations.
Technical Context
The DLPC3437CZEZ operates as the central timing and image-processing engine in DLP3310-based projection systems. It accepts pixel data via parallel or dual FPD-Link LVDS interfaces, performs real-time color space conversion, degamma, scaling, and local brightness boosting before serializing commands and pixel streams to the DMD via sub-LVDS and low-speed interfaces.
Its architecture includes an embedded frame buffer (eDRAM), programmable LED current control, auto-DMD parking on power-down, and hardware-accelerated IntelliBright™ algorithms. System integration requires coordination with DLPA300x PMICs for bias voltage generation (VOFFSET, VBIAS, VRESET) and LED driving, with strict power sequencing enforced through RESETZ and PARKZ signals.
Key Specifications

FAQ
What is the primary function of the DLPC3437CZEZ in a DLP projection system?
The DLPC3437CZEZ serves as the core display controller IC that processes incoming video data, applies image enhancement algorithms (IntelliBright™), manages timing for the DLP3310 DMD, and drives both high-speed sub-LVDS and low-speed serial interfaces. In every DLPC3437CZEZ-based system, it bridges the host processor to the DMD while enabling features like local brightness boost and one-frame latency.
Does the DLPC3437CZEZ integrate memory for frame buffering?
Yes, the DLPC3437CZEZ includes embedded DRAM (eDRAM) that provides full-frame buffering, enabling true one-frame latency operation. This eliminates external memory requirements and ensures deterministic timing for interactive applications - a key differentiator of the DLPC3437CZEZ versus earlier DLP controllers.
Can the DLPC3437CZEZ operate without a companion PMIC?
No, the DLPC3437CZEZ requires pairing with either the DLPA3000 or DLPA3005 PMIC to generate DMD-specific bias voltages (VOFFSET, VBIAS, VRESET) and drive high-current LEDs. The DLPC3437CZEZ itself does not provide power regulation - its role is strictly signal processing and interface control.
What pixel interface standards does the DLPC3437CZEZ support?
The DLPC3437CZEZ supports two physical pixel interfaces: a 24-bit parallel RGB interface with pixel clock up to 155 MHz, and dual FPD-Link LVDS lanes capable of equivalent bandwidth. Both interfaces feed the same internal video pipeline, and selection is configured at boot time via flash settings or I²C registers.
Is the DLPC3437CZEZ pin-compatible with other members of the DLPC34xx family?
No, the DLPC3437CZEZ is not pin-compatible with DLPC3435CZEZ or DLPC3477CZEZ due to differences in I/O count, power domain assignments, and peripheral pin allocations. While they share functional similarities and software compatibility, each variant uses a distinct NFBGA-201 footprint with unique pin mappings verified in their respective datasheet pin configuration tables.
