4 Does your LS1046A design offer plug-in modules like SD Card
or eMMC memory? — Analog switches enable multiple interface ports while utilizing minimum I/O pins Does your design use USB interface – Type A, Micro B or Type-C? — Load switches offer the extra protection with OVP , OCP , OTP , very critical with Type-C
4 Does your design need voltage level translators: I2C or
general purpose ? — Peripheral devices use different voltages than the processor voltage 4 Does your design need temperature sensor with alerts capability? 4 Does your system need a real time clock for time-keeping? — PCF85063A or PCF85263A for low power and PCF2129AT/2 for higher accuracy LS1046A – INTERFACE QUICK REFERENCE BROAD PORTFOLIO BEST-IN-CLASS SUPPORT TECHNOLOGY LEADERSHIP SOLUTIONS AROUND THE CORE SECURE INTERFACES AND POWER LS1046A Reference Design Interface Products Device Description Key Features/ Differentiators NX3L4684TK,115 Dual low-ohmic single-pole double-throw analog switch
