STMicroelectronics STV0974E/TR

Overview

STV0974E/TR from STMicroelectronics is a mobile imaging digital signal processor (DSP) designed exclusively for the VS6552 640×480 VGA CMOS image sensor. It performs real-time pixel defect correction, color interpolation, radial anti-vignetting, adaptive noise filtering, and M-JPEG compression at up to 30 frame/s - enabling high-fidelity viewfinder and still capture in space-constrained handheld devices.

For engineers reviewing the STV0974E/TR datasheet, STV0974E/TR pinout, STV0974E/TR application, or STV0974E/TR equivalent, key selection criteria include its VisionLink low-EMI sensor interface, programmable downscaling (1.5×–6×), ITU-R BT.656/RGB565 video output modes, ultra-low 30 µW standby power, and TFBGA-64 lead-free package compatibility with mobile camera module layouts.

Technical Context

The STV0974E/TR implements a dedicated hardware video pipeline with integrated microprocessor control: raw Bayer data from the VS6552 enters via subLVDS VisionLink interface (PCLKP/PDATAP pairs), undergoes fixed-pattern noise cancellation and defect correction, then passes through color matrix, gamma (S-curve/LCD-optimized), sharpness enhancement, and programmable downscaler stages before optional M-JPEG encoding.

It supports dual host interfaces: an 8-bit microprocessor bus with 2 KB JPEG FIFO and 10 KB non-JPEG FIFO (plus DRQ/IRQ), and parallel video output compliant with ITU-R BT.656 framing (UYVY, RGB565, RGB444). Power management includes PDN-controlled sleep mode and POR-synchronized boot.

Key Specifications

Pinout & Package

FAQ

What sensor is required for STV0974E/TR operation?

The STV0974E/TR is designed exclusively for use with the STMicroelectronics VS6552 640×480 VGA CMOS image sensor. Its VisionLink interface, timing recovery, and register map are co-optimized for this sensor - no other sensor is supported or validated. Attempting integration with alternate sensors will result in failure to acquire or process image data.

Does STV0974E/TR support RAW Bayer output?

No. The STV0974E/TR does not provide RAW Bayer output. All processing - including defect correction, color interpolation, gamma, and scaling - occurs internally. Output formats are strictly processed YUV (UYVY) or RGB (RGB565/RGB444/RGB332), or JPEG-compressed data. There is no bypass mode or register setting to expose unprocessed Bayer data.

How is flash synchronization implemented?

Flash synchronization is handled via the DIO[12] pin configured as Flash Strobe Output (FSO). The internal camera control unit asserts FSO precisely during the exposure integration window, aligned to the sensor's shutter timing. This signal directly drives external LED flash drivers and requires no host intervention or software timing calibration.

Can STV0974E/TR operate without external memory?

Yes. The STV0974E/TR contains all necessary internal RAM (including 2 KB JPEG FIFO and 10 KB non-JPEG FIFO) and ROM for firmware execution. No external SDRAM, SRAM, or Flash is required for basic operation. Host systems only need to supply configuration registers via I²C or microprocessor interface - no external code storage or frame buffer is needed.
