VS6590 0.5 Megapixel Camera Module DATA BRIEF FEATURES 1 ■ SMIA 1.0 profile 0 compliant image sensor ■ ■ ■ ■ ■ 0.5 Megapixel resolution (800H x 600V) CCP 1.0 serial video interface Two-wire control port (CCI) On-chip PLL with 6.5 to 27 MHz system clock Up to 30 frame per second (fps) progressive scan with smooth frame rate control Horizontal downscale at x1, x1.5, x2.0, x2.5 and x3.0 Operation from 2.4 V analog power supply Low EMI 1.8 V digital and I/O power supply 15 µW power down consumption 10-bit on-chip ADC Small size 1/4-inch lens fixed focus module Integral EMC shielding The VS6590 features allow straightforward integration into mobile phone designs: low EMI video interface and package/socket shielding, low wire count (8 total), embedded power management with ultra low power-down current and embedded PLL. A minimal list of external components is required: supply decoupling capacitors, CCI pull-ups and a charge-pump capacitor. The VS6590 2-element lens design ensures high quality image capture while maintaining low module height. The overall optical stack, including lens system, IR filter and sensor optical structures is developed within ST. The VS6590 package uses the second generation of SmOP (Small Optical Package) packaging technology; sensor and lens are assembled in a fully automated test and focus process for high volume and low cost production. This 0.5 Megapixel sensor fits within a space efficient form factor (9.5 x 8.5 x 6.1 mm3). APPLICATIONS ■ Mobile phone ■ ■ ■ ■ ■ ■ ■ ■ ■ DESCRIPTION The VS6590 is a 0.5 Megapixel camera module for use across a range of mobile phone platforms. The electrical and logical interfaces to the camera module are SMIA 1.0 profile 0 compliant and are capable of generating 0.5 Megapixel images at up to 30 fps. Based on the SMIA architectural concepts, the VS6590 can be used with or without image processor (e.g. STV0976). This camera module is suitable for performance-driven camera phones and cost-driven high volume designs. The embedded horizontal scaler typically enables the realization of power efficient viewfinder using host software processing. For performance driven applications, or when a different video interface is required, the STV0976 mobile imaging processor ensures state-of-the-art image reconstruction and compression of SVGA images at up to 30 fps.
