7. 7 Why choose Cypress Compatibility: Cypress I/O expanders employ industry standard I2C interface. Migrating from your existing design to PSoC will be straightforward. Integration: Cypress I/O expanders have the widest range of I/Os from 20(9520) to 60(9560). All the I/Os are bi-directional and number of I/Os can be expanded to thousands via soft addressing. Non-Volatile Configuration: No more worries if the power goes out. Cypress I/O expanders will get right back to work fully configured once the power is restored.

8. 8 Why choose Cypress Maximum Available Slave device Address (I2C): For your complex design, imagine being able to have the option of adding up to 7000 I/Os and up to 3MB of EEPROM in your application. PWMs: Cypress I/O expanders have the widest range of PWMs available on the market 4(9520), 8(9540), and 16(9560). All pins can be connected. One PSoC will be able to replace up to 16 competitor’s parts. EEPROM: Cypress I/O expanders have more user accessible serial EEPROM than any competitors.

9. 9 Why choose Cypress Competitive Price: PSoC has the lowest price per bit (9560) on the market.
