Texas Instruments DLPC900AZPC

Overview

DLPC900AZPC from Texas Instruments is a high-performance digital micromirror device (DMD) controller supporting DLP500YX, DLP5500, DLP6500, DLP670S, and DLP9000 DMDs for industrial light control. It delivers programmable pattern rates up to 16.1 kHz (1-bit pre-stored mode), integrates 128 MB internal DRAM, and supports dual 24-bit RGB video inputs up to 120 Hz for WQXGA resolution.

For engineers reviewing the DLPC900AZPC datasheet, DLPC900AZPC pinout, DLPC900AZPC application, or DLPC900AZPC equivalent, this controller enables precise synchronization with cameras/sensors via two configurable triggers, offers USB 1.1 and three I²C interfaces, and provides fully programmable GPIO/PWM for adaptive lighting and 3D scanning system integration.

Technical Context

The DLPC900AZPC implements a scalable architecture with dual pixel input ports (Port 1 and Port 2), each supporting 24-bit RGB/YUV data at up to 120 Hz, and configurable as independent 24-bit ports or combined 48-bit interface for two-pixel-per-clock operation. Its DMD interface uses dual-channel LVDS (A and B), each with 16-bit differential serial data lanes, dedicated differential clocks (DCKA_P/N, DCKB_P/N), and serial control (SCA_P/N, SCB_P/N).

It integrates a system oscillator input (MOSC) with 25 ms stabilization requirement post-POSENSE, programmable output clock OCLKA (default 787 kHz), and three JTAG debug interfaces (TCK/TDI/TDO1 for boundary scan; TMS2/TDO2/RTCK for ICE). Power sequencing relies on POSENSE and PWRGOOD signals with hysteresis, driving three active-low reset outputs (EXT_ARSTZ, CTRL_ARSTZ, AFE_ARSTZ) with ≥2 ms assertion time.

FAQ

What DMD devices does the DLPC900AZPC support?

The DLPC900AZPC supports DLP500YX, DLP5500, DLP6500, DLP670S, and DLP9000 digital micromirror devices. For DLP670S and DLP9000, two DLPC900AZPC controllers are required in tandem to manage full-resolution pattern data and timing. The controller's LVDS DMD interface and 128 MB DRAM are optimized for these high-density DMDs' bandwidth and buffering needs.

Does the DLPC900AZPC include internal memory for pattern storage?

Yes, the DLPC900AZPC integrates 128 MB of internal DRAM, sufficient to buffer between 400 and 1024 1-bit patterns depending on the connected DMD's resolution. This eliminates the need for external frame buffers in most industrial applications and reduces system latency by enabling direct pattern access from on-chip memory during high-speed projection sequences.

How does the DLPC900AZPC synchronize with external cameras or sensors?

The DLPC900AZPC provides two configurable input and output trigger lines that can be programmed for precise timing alignment with external cameras or sensors. These triggers operate with sub-microsecond jitter and support both hardware-level synchronization and software-defined delay offsets, ensuring deterministic latency between DMD pattern display and image capture in 3D scanning and machine vision systems.

What video input formats and resolutions does the DLPC900AZPC accept?

The DLPC900AZPC accepts dual 24-bit RGB, YUV, or YCrCb video inputs up to 120 Hz, supporting standard formats from XGA to WQXGA. It natively handles DLP9000 (WQXGA), DLP500YX (2048×1200), and DLP670S (2716×1600) - though the latter two require two DLPC900AZPC controllers operating in coordinated mode for full-resolution video streaming.

What interfaces are available for configuring and controlling the DLPC900AZPC?

The DLPC900AZPC offers one USB 1.1 target port for host PC configuration, three I²C ports for peripheral communication (e.g., temperature sensors, EEPROMs), and dedicated LED enable/PWM generator outputs for illumination control. These interfaces allow full system initialization, real-time parameter adjustment, and closed-loop light modulation without requiring additional microcontrollers or FPGAs.
