Overview
CMOS LSI No.
*5601 LC82151 Single-Chip Facsimile Controller Preliminary Overview The LC82151 is a facsimile controller that integrates the main functions required by facsimile systems on a single chip.
The LC82151 includes a FAX modem with ADPCM and HDLC functions, image processing functions that can create high-quality binary image data without external memory, a CODEC accelerator, a CPU and CPU peripheral circuits, general-purpose I/O ports, and other functions.
A facsimile system with excellent costperformance characteristics can be created easily by providing ROM and RAM.
• Modem – Group 3 FAX modem ITU-T V.
29 (9600, 7200, and 4800 bps) ITU-T V.
27ter (4800 and 2400 bps) ITU-T V.
21ch2 (300 bps) – Simultaneous high/low-speed wait function – Short training function (ITU-T V.
27ter only) – HDLC function (for all transmission speeds) – Synthesizer function – Caller ID function Bell 202 (1200 bps) ITU-T V.
23 (1200 bps) – ADPCM function Encoding: 2, 3, or 4 bits Sampling frequencies: 9.
6, 7.
2, 4.
8, and 3.
6 kHz – RTC low-voltage backup – 5-V single-voltage power supply Functions • CPU and peripheral circuits – High-speed 16-bit CPU (65C816) operating at 7.
4 MHz – 16-MB program address space – CODEC accelerator – Two-channel DMA controller – Four 16-bit timers – 16-bit watchdog timer – TPH interface – Serial I/O interface – Parallel I/O: 10 to 43 pins • Image processing – Processes 2048 pixels per line – Processing speed: 540 ns per pixel (maximum) – Built-in 8-bit A/D converter (Includes a sensor signal delay function.
) – Sensor drive circuit (Supports CCDs and all major CIS devices.
) – Distortion correction (White distortion: 8-pixel averaging correction, black correction: Allows the black correction subtraction data to be set.
) – γ-correction (Supports user-defined correction curves.
) – Simple binary conversion processing (fixed threshold and density-adaptive threshold) – Halftone processing error diffusion method (64 levels) – Image reduction (decimation, fine blac...
