Overview
INTEGRATED CIRCUITS DATA SHEET SAA7215; SAA7216; SAA7221 Integrated MPEG AVGD decoders Preliminary specification Supersedes data of 1998 Sep 11 File under Integrated Circuits, IC02 2000 Jan 31 Philips Semiconductors Preliminary specification Integrated MPEG AVGD decoders FEATURES General features • Integrated MPEG AVGD decoder: audio, video and graphics decoding and digital video encoding • 5 planes display chain: background colour, background plane, MPEG display plane, graphics plane and cursor plane • 16-Mbit or 32-Mbit external Synchronous DRAM (SDRAM) for MPEG audio and video decoding and graphics data storage • Single or double external SDRAM organized as 1 M × 16 or 2 × 1 M × 16 (two independent 16-bit data bus) interfacing at 81 MHz.
Due to efficient memory use in MPEG decoding, more than 1 Mbit is available for graphics in the single SDRAM configuration whereas 17 Mbits are available in the double SDRAM configuration.
• All basic operations of the AVGD decoder are possible i...
