What this DLP controller is and where it fits
The Texas Instruments DLPC3438CZEZ is a DLP display driver controller designed to drive DLP2010 and similar micromirror arrays in compact projection and light-steering applications. It communicates over an I²C interface and requires a 1.1V core supply. The part is housed in a 201-NFBGA (13x13) package and operates from -30°C to 85°C, making it suitable for consumer, commercial, and some industrial projection systems where the ambient stays within that window.
Package and mounting
The 201-NFBGA (13x13 mm) is a fine-pitch BGA. Reworking this by hand requires a preheat plate, a hot-air nozzle matched to the body size, and a stencil for reballing.
Supply rail and interface — what to budget
The 1.1V core supply is a dedicated rail — it is not the same as the DLP micromirror high-voltage supply or the I/O voltage. Plan for a separate 1.1V LDO or DC-DC with adequate decoupling right at the BGA balls. The I²C interface runs at standard or fast mode; pull-up resistors to the appropriate I/O voltage (likely 1.8V or 3.3V, depending on the host) need to be sized for the bus capacitance. No other interfaces (SPI, parallel) are listed, so the host talks exclusively over I²C.
Temperature grade — the operating envelope
Rated from -30°C to 85°C, this part covers most indoor and many outdoor sheltered applications. Avoid designs where the ambient dips below -30°C or the junction temperature exceeds 85°C without thermal analysis.
Lifecycle and sourcing posture
The DLPC3438CZEZ is listed as Active (current lifecycle stage) and ROHS3 Compliant. There is no pin-compatible second source listed — this is a single-source TI part, so securing stock through a distributor with a confirmed lead time is the standard procurement path.
