DUAL MODE CAMERA PROCESSOR
1.General description: SN9C2028AF is designed for low cost dual mode CMOS camera solution. It highly integrated single chip solution that included CMOS sensor interface, SDRAM interface, USB interface, compression engine, LCD driver, embedded 16bit DSP and low battery detection function. This dual mode camera solution is not only for DSC function but also with the live video mode when attached to PC. SN9C2028AF provide a solution that can makes balance both in performance and price and most flexible in function for customers design their own style. 2. Feature: Dual mode camera- PC camera mode and DSC mode. Support - Hynix- HV7131D, HV7131E (VGA) and HV7121B (CIF),
Pixart-PAS202B (VGA) and PAS106B (CIF), ICMEDIA -ICM105A, ICM105B (VGA) and ICM102A (CIF), TASC- TAS5130B (VGA) and TAS5110B (CIF) CMOS image sensors.
9-bit CMOS image sensor raw data. Provide scaling and panning function. Built in proprietary compression engine. Up to 30fps @ CIF, 12fps @VGA in PC video mode. Support SDRAM 4Mb, 16Mb, 64Mb, 128Mb Embedded 16bit-DSP for camera control and USB transceiver. USB 1.1 compliance and support suspend mode. 6 USB endpoints: Control pipe, Iso chronous pipe, Bulk pipe, Interrupt pipe and Audio pipe. Build in 8 segment x 4 common, 1/3 bias status LCD driver. Embedded low battery detection function. Support flashlight function. 12MHz crystal and 3.3Volt only. 128 pin LQFP package.
