Description

The CXD9788AR is a member of the Single-Chip FaxEngine product family by Conexant™, a provider of semiconductor solutions for broadband communications. This product is categorized under IC Chips. The CXD9788AR is a complete facsimile machine that consists of an embedded modem Digital Signal Processor (DSP) and a separate Integrated Analog (IA) device (20415). The CXD9788AR together with the supporting firmware and evaluation system provides with a complete fax system.

Specifications and features

• Microprocessor and Bus Interface
• MC24 Central Processing Unit with up to 10 MHz CPU clock speed
• External Bus that supports connection to external ROM, SRAM, DRAM, and operator panel
• DRAM Controller with support for up to 8 MB in two blocks and organizations supported: 4 or 8-bit
• Flash memory support that includes NAND and NOR-type support, and serial NAND support, and NOR-type memory up to 2 MB
• Six dedicated internal DMA channels for scanner, thermal printer, and T.4/T.6 access of internal and/or external Memory

Application Scenarios

The CXD9788AR can be used as a key component in the fax machine manufacturing industry. It is a complete fax system that only requires power supply, scanner, and printer mechanism components to complete the machine. The CXD9788AR is suitable for use in office environments that require an efficient fax system solution.

Comparison

• Complete fax machine solution with embedded modem DSP, separate Integrated Analog device (20415), and supporting firmware and evaluation system
• Support for up to 8 MB memory in two blocks
• Six dedicated internal DMA channels for scanner, thermal printer, and T.4/T.6 access of internal and/or external Memory

• May not be suitable for environments that require more advanced fax system capabilities beyond basic transmission and reception
• May not be cost-effective for applications that require only single functionality
