MN86062

For Communications Equipment MN86062 CODEC LSI for Facsimile Images Overview The MN86062 is a high-speed LSI codec for compressing and decompressing images using the MH, MR, and MMR standard compression methods specified in the ITU-T T.4 and T.6 recommendation. Registers and other settings provide flexible support for a variety of processing. Features Compression methods MH, MR, and MMR Operating mode: Page mode Bus configuration: Choice of dual- or single-bus operation Decoding error processing: Choice of replacing with the previous line or a white line Image bus configuration: 8 bits, maximum 16 megabytes address space of image bus, 2-channel master DMA System bus configuration: X80 interface compatible, 8 bits, 2-channel slave DMA Pixels per line: maximum 64K, in byte increments Concurrent DMA transfers over image bus and command processing Support for pointer management for image buffer Wide selection of independent parameters for coding, decoding, transfers between buses, and DMA transfersr Support for time-shared processing by line for both coding and decoding Applications Facsimile equipment MN86062 Pin Assignment For Communications Equipment VSS2 VDD2 TACK VSS3 VDD3 N.C.3 ID7 ID6 ID5 ID4 ID3 ID2 ID1 ID0 VDD4 VSS4 TEST2 TEST1 TEST0 NACKD NACKC 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 N.C.1 N.C.2 IA18 IA17 IA16 IA15 IA14 IA13 IA12 IA11 IA10 IA9 IA8 IA7 IA6 IA5 IA4 IA3 IA2 IA1 IA0 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 63 62...
