DLP display controller for pico projection
The Texas Instruments DLPC3433CZVB is a DLP display driver controller designed for compact pico projection systems. It manages the DLP micromirror array, handling pattern sequencing and illumination control. The I²C interface allows a host processor to configure display parameters and read back status. This part is the digital brain behind the optical engine, not the power stage or LED driver.
Supply rail and temperature grade
The core logic runs from a single 1.1V supply rail, which is typical for deep-submicron DLP controllers. The -30°C to 85°C operating temperature range covers most indoor and automotive cabin applications, though it does not reach the full -40°C automotive cold-crank requirement. If the system sees sustained -40°C ambient, check the optical engine's cold-start behaviour separately.
Package and footprint
The DLPC3433CZVB is supplied in a 176-VFBGA package (supplier device package 176-NFBGA, 7x7 mm). This is a fine-pitch BGA requiring careful PCB layout — the NSMD pads need a soldermask-defined opening and a via-in-pad or microvia escape pattern for the inner rows. The Tray shipping medium means the parts are delivered in antistatic trays, not tape-and-reel; plan for pick-and-place handling accordingly.
Lifecycle and compliance
It is ROHS3 compliant, which covers the EU RoHS exemption list through 2024. The active status means TI continues to support it with datasheet revisions and application notes.
Sourcing posture
The active lifecycle means we can support both prototype quantities and production-run volumes without last-time-buy constraints.
