Ordering Information/Selector Guide
General Description
The MAXQ613 is a low-power, 16-bit MAXQ
®
microcon-
troller designed for low-power applications including uni-
versal remote controls, consumer electronics, and white
goods. The device combines a powerful 16-bit RISC
microcontroller and integrated peripherals including a
universal synchronous/asynchronous receiver-transmit-
ter (USART) and an SPI master/slave communications
port, along with an IR module with carrier frequency
generation and flexible port I/O capable of multiplexed
keypad control.
The device includes 48KB of flash program memory and
1.5KB of data SRAM. Intellectual property (IP) protec-
tion is provided by a secure MMU that supports multiple
application privilege levels and protects code against
copying and reverse engineering. Privilege levels enable
vendors to provide libraries and applications to execute
on the device, while limiting access to only data and
code allowed by their privilege level.
For the ultimate in low-power battery-operated perfor-
mance, the device includes an ultra-low-power stop
mode (0.2µA typ). In this mode, the minimum amount of
circuitry is powered. Wake-up sources include external
interrupts, the power-fail interrupt, and a timer interrupt.
The microcontroller runs from a wide 1.70V to 3.6V oper-
ating voltage.
