Product details
Overview
DLPC3426ZVB from Texas Instruments is a display controller IC designed specifically for the DLP230NPSE .23-inch 1080p digital micromirror device (DMD), supporting up to 1080p input resolution at frame rates up to 240Hz (60Hz native), featuring embedded eDRAM, IntelliBright™ image processing, and 1D keystone correction. It enables compact, low-power pico projector systems with programmable LED current control and auto-DMD parking.
For engineers reviewing the DLPC3426ZVB datasheet, DLPC3426ZVB pinout, DLPC3426ZVB application, or DLPC3426ZVB equivalent, key selection considerations include its NFBGA-176 package, 1.1V core/1.8V I/O power domains, SubLVDS DMD interface timing, parallel 24-bit RGB input support up to 155MHz pixel clock, and compatibility with DLPA2005/DLPA3005 PMICs for illumination control.
Technical Context
The DLPC3426ZVB implements dual PLL architecture - MCG for system clock generation and DCG for DMD-specific timing - enabling precise synchronization between pixel data, DMD subframe sequencing, and LED illumination. Its integrated eDRAM buffers full-frame video data while offloading host processor bandwidth.
It supports two distinct DMD interface modes: low-speed serial (LS) for configuration and status, and high-speed SubLVDS (HS) for real-time mirror actuation data transfer. The controller executes CAIC (Content Adaptive Illumination Control) and LABB (Local Area Brightness Boost) in hardware, using pixel-level luminance analysis to dynamically adjust LED drive and local contrast enhancement.

FAQ
What is the primary DMD compatibility for DLPC3426ZVB?
The DLPC3426ZVB is specifically designed for the DLP230NPSE .23-inch 1080p digital micromirror device. It is not compatible with the higher-brightness DLP230NP variant - that requires DLPC3436ZVB. The DLPC3426ZVB firmware and timing parameters are calibrated for DLP230NPSE's electrical and optical characteristics, including its lower power consumption and illumination requirements.
Does DLPC3426ZVB support MIPI DSI input?
No, DLPC3426ZVB does not support MIPI DSI input. Its primary video interface is a 24-bit parallel RGB port with programmable sync signals (PCLK, HSYNC_CS, VSYNC_WE). DSI support was introduced in later-generation controllers such as DLPC3476ZVB. For DSI-based designs, DLPC3426ZVB requires an external bridge IC or FPGA conversion to parallel format.
What power supplies are required for DLPC3426ZVB operation?
DLPC3426ZVB requires three independent power domains: 1.1V for core logic (VDD), 1.8V for general I/O (VCC18), 1.8V for host/parallel interface (VCC_INTF), and 1.8–3.3V for SPI flash (VCC_FLSH). Additionally, dedicated 1.1V supplies are needed for PLL blocks (VDD_PLLM/VDD_PLLD), each with corresponding ground returns (VSS_PLLM/VSS_PLLD). Proper sequencing - VDD first, then I/O rails - is mandatory per TI's power-up recommendations.
How does DLPC3426ZVB implement Content Adaptive Illumination Control (CAIC)?
DLPC3426ZVB executes CAIC in dedicated hardware using real-time analysis of incoming pixel luminance data. It dynamically adjusts LED current per frame based on histogram-derived scene brightness, reducing power and heat during dark scenes while preserving peak brightness in highlights. This function is part of the IntelliBright™ suite and operates independently of host software - no driver intervention is required for basic CAIC activation.
Can DLPC3426ZVB be used without external flash memory?
No, DLPC3426ZVB requires external SPI flash memory for firmware storage and boot. The controller lacks internal non-volatile program memory and relies on SPI0 interface (pins SPI0_CLK, SPI0_CSZ0, SPI0_DIN, SPI0_DOUT) to load configuration and image processing algorithms at power-up. A minimum of 8MB QSPI flash is recommended to accommodate full firmware, calibration data, and splash screen assets for DLPC3426ZVB-based systems.
