STMicroelectronics STV0976

Overview

STV0976 from STMicroelectronics is a low-power digital image processor for SMIA-compliant camera modules, supporting 1.0 MP (1152×864) at 15 fps or SVGA (800×600) at 30 fps. It integrates defect correction, demosaicing, gamma correction, color space conversion, and JPEG compression with programmable quantization tables, targeting mobile imaging systems with embedded camera control and CIF-class downscaling.

For engineers reviewing the STV0976 datasheet, STV0976 pinout, STV0976 application, or STV0976 equivalent, key selection criteria include SMIA Class 0 (208 Mbit/s) sensor/host interface compatibility, 1.8 V single-supply operation, TFBGA-56 package constraints, JPEG target file size programming, and ITU-R BT.656-4 YUV 4:2:2 output support.

Technical Context

The STV0976 implements a dedicated SMIA Class 0 receiver/transmitter pair for simultaneous high-speed sensor input and host output at up to 208 Mbit/s, both using 1.8 V LVDS signaling. Its internal video pipeline includes configurable gamma curves (standard/S-curve), arbitrary image cropping, and a fine-grained downscaler with 13 ×0.5 steps (1×–7×) plus 5 ×1.0 steps (7×–12×).

It embeds an autonomous camera controller supporting automatic exposure, white balance, black level compensation, and 50/60 Hz flicker detection-executed without external CPU intervention. JPEG compression operates directly on YUV 4:2:2 data with programmable quantization tables and target file size control, while output formats include YUV 4:2:2, RGB 565, RGB 444, and JPEG with embedded syncs.

Key Specifications

Pinout & Package

STV0976 uses a TFBGA-56 AFOP lead-free package (6 mm × 6 mm × 1.2 mm, WLH), pin-compatible with STV0974. The package supports fine-pitch routing and thermal dissipation suitable for compact mobile PCBs.

FAQ

Does STV0976 support RAW sensor data output?

No. The STV0976 processes incoming Bayer data internally and outputs only processed formats: YUV 4:2:2, RGB 565, RGB 444, or JPEG. It does not provide bypass or RAW pass-through modes-demosaicing and noise filtering are fixed-function stages in its pipeline.

What clock frequencies are supported for the external crystal input?

The STV0976 accepts external clock inputs from 6.5 MHz to 27 MHz, with 13 MHz being the typical value. The clock must be a clean square wave; jitter tolerance is specified at ±100 ps RMS for stable SMIA link timing and JPEG encoding accuracy.

Can STV0976 operate without an external microcontroller?

Yes-for basic operation. Its embedded camera controller handles AE, AWB, flicker detection, and black level compensation autonomously. However, initial register configuration, JPEG quantization table loading, and downscale ratio selection require I²C (CCI) setup by a host processor.

Is the TFBGA-56 package RoHS-compliant and lead-free?

Yes. The STV0976E and STV0976E/TR variants use an AFOP (Advanced Fine-Pitch Organic) lead-free package conforming to RoHS Directive 2011/65/EU. The "E" suffix explicitly denotes lead-free, halogen-free, and green material composition per STMicroelectronics specification.
