CENGLH7A400-10-402HI

Overview

The Beacon EmbeddedWorks CENGLH7A400-10-402HI is a System on Module based on the Sharp LH7A400 ARM922TDMI RISC microprocessor. It operates at up to 166 MHz with an 83 MHz bus speed within an industrial temperature range of -40°C to +85°C. The module integrates 32 MBytes of SDRAM and 8 MBytes of NOR Flash. Key peripherals include a 10/100 BASE-T Ethernet controller, Wolfson WM9708 audio codec, ADS7843 touch screen controller, USB 2.0 Full Speed device interface, three UARTs, and CompactFlash support. It utilizes a 144-pin SODIMM connector for integration.

Feature Summary

• Sharp LH7A400 processor running at 166 MHz (-40 to 85°C)
• 32 MB SDRAM and 8 MB NOR Flash memory
• Integrated 10/100 Ethernet, Audio Codec, and Touch Controller
• Industrial temperature rating (-40 to 85°C)

Applications

• Embedded product development requiring extended temperature ranges
• Custom baseboard designs utilizing standard expansion connectors
• Industrial automation and control systems

Procurement Notes

Verify component availability directly with the manufacturer or authorized distributors. Confirm that the specific ordering suffix matches the required industrial temperature range (-40 to 85°C) and memory configuration (32MB SDRAM, 8MB NOR). Ensure compatibility with intended operating system BSPs such as Windows CE, Linux, or VxWorks before procurement.

Selection Notes

Select this model when an industrial temperature rating is mandatory. Compare against the commercial variant (CENGLH7A400-10-402HC), which supports 0 to 70°C. Verify if the 32MB SDRAM and 8MB NOR Flash capacities meet application requirements; higher capacity options like the 50-series are available if more memory is needed.

Part Context

This module belongs to the LH7A400 Card Engine family developed by Logic Product Development, now part of Beacon EmbeddedWorks. The series provides a compact hardware and software solution for OEMs, featuring a common reference pin-out to facilitate migration to next-generation microprocessors while maintaining form factor compatibility.

Replacement Considerations

The CENGLH7A400-10-402HC serves as a functional substitute with identical specifications except for a commercial temperature range (0 to 70°C). For increased memory, the CENGLH7A400-10-504HI offers 64MB SDRAM and 32MB NOR Flash within the same industrial temperature envelope.
