Product details
Overview
DLPC3435CZEZ from Texas Instruments is a digital display controller IC designed to drive the DLP2010 (.2 WVGA) digital micromirror device (DMD), supporting input resolutions up to 720p, frame rates up to 120Hz for 2D/3D, and 24-bit parallel/BT656 pixel interfaces with pixel clock up to 150 MHz. It integrates embedded frame memory (eDRAM), IntelliBright™ image processing, and auto DMD parking for embedded projection in space-constrained, low-power systems.
For engineers reviewing the DLPC3435CZEZ datasheet, DLPC3435CZEZ pinout, DLPC3435CZEZ application, or DLPC3435CZEZ equivalent, key selection considerations include its 201-pin NFBGA (13 × 13 mm, 0.8-mm pitch) package, absence of MIPI DSI support (unlike DLPC3430), dual I²C control ports, sub-LVDS DMD interface timing compliance, and programmable LED current control for RGB illumination sequencing.
Technical Context
The DLPC3435CZEZ implements a dedicated DMD interface with high-speed sub-LVDS signaling (16 differential write data lanes + differential clock) and low-speed serial configuration, enabling precise mirror actuation timing for DLP2010. Its pixel processing pipeline includes hardware-accelerated 1D keystone correction, field-scaled de-interlacing, and 4:2:2 to 4:4:4 chroma interpolation - all operating on embedded eDRAM without external frame buffer dependency.
System-level integration is managed via dual I²C slave interfaces (IIC0/IIC1), SPI0 for flash communication, and GPIOs configurable for keypad sensing or motor feedback. Power sequencing requires PARKZ assertion before RESETZ de-assertion, and DMD_DEN_ARSTZ combines driver enable and reset functions with hysteresis buffering for robust DMD bias control.
Key Specifications

Pinout & Package
DLPC3435CZEZ uses a 201-pin NFBGA (ZEZ package), 13.0 × 13.0 mm body size, 0.8-mm ball pitch. Thermal pad exposed on bottom for enhanced heat dissipation in portable projection modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DMD_HS_CLK_P / DMD_HS_CLK_N | DMD high-speed interface clock | Differential sub-LVDS clock driving DLP2010 mirror timing; requires matched trace length and controlled impedance (100 Ω). |
| DMD_HS_WDATA_A_P / _N through _H_P / _N | DMD high-speed write data lanes | 16-bit sub-LVDS data bus (8 differential pairs); maps to DMD mirror row/column addressing per TI configuration tables. |
| IIC0_SCL / IIC0_SDA | I²C slave control interface | 3.6-V tolerant, open-drain bidirectional bus for host processor configuration; requires external pullups to VCC_INTF (1.8/2.5/3.3 V). |
| PARKZ | DMD fast park control | Active-low hysteresis input; must be held high during normal operation and pulsed low ≥32 µs before power removal to initiate mirror parking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar display controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DLPC3430CZEZ | 176-pin NFBGA (7 × 7 mm); supports MIPI DSI (1–4 lanes, up to 470 Mbps); lacks DMD sub-LVDS lane count for highest-resolution DMD variants. | Better suited for designs requiring DSI input from mobile APs; smaller footprint but lower DMD interface bandwidth headroom. | Select DLPC3430CZEZ when DSI source integration is required and board space is constrained; verify DMD timing compatibility with target DMD variant. |
| DLPC3478CZEZ | Successor IC supporting DLP3310 (.33 WVGA) and DLP4710 (.47 WVGA) DMDs; higher pixel clock (200 MHz), added HDMI receiver, and enhanced IntelliBright™ algorithms. | Enables higher-resolution projection (1080p) and direct HDMI connectivity; not backward-compatible with DLP2010 timing or pinout. | Choose DLPC3478CZEZ for next-generation designs targeting >720p resolution or HDMI-native inputs; requires full hardware redesign due to non-pin-compatible package and interface changes. |
Compared with DLPC3430CZEZ, DLPC3435CZEZ offers greater DMD interface bandwidth and thermal margin via its larger 201-pin NFBGA, but omits DSI - making it optimal for parallel/BT656-based embedded systems prioritizing DLP2010 reliability over mobile interface flexibility. DLPC3478CZEZ extends capability beyond DLPC3435CZEZ in resolution and integration, at the cost of compatibility and design continuity.

FAQ
What is the primary function of the DLPC3435CZEZ in a DLP projection system?
The DLPC3435CZEZ serves as the core display controller IC that interfaces between a video source (e.g., mobile SoC or FPGA) and the DLP2010 digital micromirror device. It processes incoming pixel data, applies image enhancements like IntelliBright™ and 1D keystone correction, manages DMD timing via sub-LVDS signals, and controls RGB LED illumination sequencing - all within a single chip with embedded eDRAM. This eliminates external memory and reduces system complexity in portable projection designs.
Does the DLPC3435CZEZ support MIPI DSI interface?
No, the DLPC3435CZEZ does not support MIPI DSI. According to TI's official documentation (DLPS038C, Rev C), DSI is available only on the DLPC3430 variant. The DLPC3435CZEZ supports parallel and BT656 pixel interfaces exclusively, with a maximum pixel clock of 150 MHz. Designers requiring DSI must select DLPC3430CZEZ or a newer controller such as DLPC3478CZEZ.
What package type and dimensions does the DLPC3435CZEZ use?
The DLPC3435CZEZ uses a 201-pin NFBGA package designated ZEZ, with nominal body dimensions of 13.0 × 13.0 mm and a 0.8-mm ball pitch. It features an exposed thermal pad on the underside for improved heat dissipation - essential for sustained operation in thermally constrained embedded projection modules. This contrasts with the smaller 176-pin ZVB package used by DLPC3430CZEZ (7.0 × 7.0 mm).
How does the DLPC3435CZEZ handle DMD power-down sequencing?
The DLPC3435CZEZ supports two DMD parking modes: fast park (via PARKZ pin, ≥32 µs low pulse before power removal) and normal park (triggered via GPIO_08, up to 500 µs duration). Fast park is intended for imminent power loss (e.g., battery cutoff), while normal park maximizes DMD lifetime. The DLPC3435CZEZ also asserts DMD_DEN_ARSTZ low after parking to disable the DMD driver, ensuring safe mirror state retention during power-off.
Can the DLPC3435CZEZ operate without external flash memory?
No, external flash memory is required for DLPC3435CZEZ operation. The device relies on external SPI flash to store firmware, configuration data, and image processing parameters. While it includes embedded eDRAM for frame buffering, it lacks on-chip non-volatile storage. TI reference designs specify a 16-Mbit or larger SPI flash device connected to the SPI0 interface (SPI0_CLK, SPI0_DIN, SPI0_DOUT, SPI0_CSZ0/CSZ1) for reliable boot and runtime operation.
