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.)
