To further extend battery life, the MAXQ622 consumes an ultra-low 300nA (typ) in stop-mode operation. These unique power-saving capabilities make the MAXQ622 ideal for remote controls, security systems, thermostats, blood pressure monitors, and a wide variety of other consumer and medical applications.
The MAXQ622 includes 128KB of flash memory, 6KB of data RAM, dual USART ports, dual SPI(TM) master/slave communication ports, an I2C port, an infrared (IR) module with carrier-frequency generation, and up to 56 general-purpose I/O pins. Additionally, it provides a secure memory-management unit (MMU) to prevent device cloning and unauthorized access to sensitive application code.
The MAXQ622 is available in a 64-pin LQFP package and as bare die (contact the factory for detailed information). Prices start at $2.09 (1000-up, FOB USA). The MAXQ612 is also available for those applications not needing USB capabilities.
