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 cost-
performance characteristics can be created easily by
providing ROM and RAM.
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 black line retention,
and fine white line retention)
• 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
