The MAXQ610 16-bit MAXQ® microcontroller features a high performance, single cycle MAXQ RISC core with the industry’s best MIPS/mA rating, offering same performance as competing products at significantly lower clock rates. The microcontroller includes 64KB of flash memory, 2KB data RAM, a soft stack, 16 general-purpose registers, and three data pointers. The device can switch to an ultra low power stop mode when active device operation is not required to reduce quiescent power consumption to less than 0.2µA typical and 2.0µA maximum, thereby increasing battery life, making it ideal for low power applications such as universal remote controls, consumer electronics and white goods. The device can operate in a flexible 1.7oV to 3.6V voltage range.
The MAXQ610 provides memory protection features such as separating code memory into system, user loader and user application areas and optional prevention from reading and writing to these areas, using privilege levels for code, and password protected access to in-system programming, in-application programming and in-circuit debugging functions. An internal watch dog timer protects the system from electrical noise or ESD upsets that can cause uncontrolled processor operation. Integrated peripherals include two USART communication ports and an integrated Serial Peripheral Interface for synchronous communication with peripheral devices in a multiple master or multiple slave system. Other notable features include 2 16 bit programmable Timers/counters with Prescaler and Capture/Compare, Power Fail warning, Power-on Reset/Brownout reset and Automatic IR Carrier Frequency Generation and Modulation.
