R96FE

The R96FE FAXENGINET"' provides a complete set of facsimile machine control functions integrated into a 2-package VLSI device set. This integration reduces the manufacturer's hardware and development costs by elimihating external components. The device set consists of an Integrated Facsimile Controller [IFC) and a 9600 bps MONOFAX@ modem. The IFC performs the primary facsimile machine control and monitoring functions interfacing with the major fax machine components. Scanner, printer, and keyboard interfaces are included as are motor control drivers and the modem interface. These functions and interfaces are programmable to support a wide range of hardware peripherals. CCITT T.4 data compressionidecompression functions (MH and MR) are implemented by the IFC. Fax machine video processing functions are provided utilizing an on-board flash ND converter for up to 64 levels of gray scale. The IFC is supplied in an industry-standard 160-pin plastic quad fiat package. The MONOFAX modem is a synchronous 9600 bps half-duplex modem (R96DF or R96VF) which offers connectivity and compatibility with fax machines world-wide. An R96FE Development System can be purchased to reduce the manufacturer's design costs and time-to-market. The R96FE Development System includes: 1. The FAXENGINE Evaluation System a stand-alone development board that acts as the fax machine motherboard. The FEES includes an IFC socket; ROM and RAM; LCD and keyboard/LED modules; speaker; phone jack; printer and scanner interfaces; and data access arrangement (DAA) circuitry. Video processing, modem, and DAA daughterboards are also included. 2. A FAXENGINE ROM Emulator a personal computer-based code development aid with breakpoint and trace capability for debugging customer-created firmware that will operate in the R96FE external ROM. 3. A royalty free license to use the development software consisting of RockweIl`s core macros (high-levei routines common to fax machines) and core primitives (low-level routines for accessing FAXENGINE hardware) supplied in object code. An example application program for a typical complete fax machine is supplied in assembly source code. This example code, although not intended for producticn, can be used as a basis for developing a customer's specific fax machine application.

The features of R96FE can be summarized as (1)integrates facsimile control circuitry: reduces device count; saves board space; simpifies design; reduces production cost; reduces development time and cost; reduces power dissipation; (2)facsimile processing firmware provided: Reduces development time and cost; macros and primitives in object code; exampie application in assembly source code; (3)T.4 MH/MR compression/decompression in hardware; (4)programmable thermal printer interface: up to 9 strobes; onchip thermal head temperature A/D converter; (5)programmable scanner interface: no extemal sample and hold required; scan widths to 2048 pixels (B4); 5 ms minimum scan time; (6)programmable control for two stepper motors; (7)programmable operator panel interface:32 keys, 8 LEDs, one LCD module; (8)programmable tone output for operator alert; (9)video processing: 6-bit flash A/D converter with voltage reference in; (10)puts supports external background correction; scanner shading correction (8 bits/pixel)1 correction per 8 pixels with internal RAM/1 correction per pixel with external RAM; configurabIe dither table (up to an 8 x 8 pattern); (11)internal MC19 CPU:7 MHz clock speed; programmable wait states for external devices; (12)26 to 34 general purpose input/output (GPIO) pins.
