Baseline Cost Analysis
Parts: Processor: ~$20 FPGA: ~$50 SRAM: ~$15 FLASH: ~$15 LCD and KEYPAD: ~$15 MP3 DECODER: ~$20TOTAL: ~$135
Globex Proprietary Competition Sensitive
Production Cost Analysis
Construction: 4-Layer Board: ~$200 Populate Board: ~$60 Production Labor Costs: NONE!TOTAL: ~$260
Final Total: $395
Globex Proprietary Competition Sensitive
Market Analysis
Large scale production cost per unit $75
Expected selling price of unit $150
Projected market share 15-20%
PROFIT $75 x 1million units = $75,000,000/year Tech support = $1,000,000 of revenue and
virtually no cost
Globex Proprietary Competition Sensitive
Societal Implications No significant environmental impact Increases standard MP3 player functionality Eliminates the need to buy multiple
electronic devices
Less battery disposal Possible illegal FM broadcast
