MAXQ618
16-Bit Microcontroller with Infrared Module
General Description
Features
®
The MAXQ618 is a low-power, 16-bit MAXQ microcon-
S High-Performance, Low-Power, 16-Bit RISC Core
S DC to 12MHz Operation Across Entire Operating Range
S 1.70V to 3.6V Operating Voltage
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 two
universal synchronous/asynchronous receiver-transmit-
ters (USARTs) 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.
S 33 Total Instructions for Simplified Programming
S Three Independent Data Pointers Accelerate Data
Movement with Automatic Increment/Decrement
S Dedicated Pointer for Direct Read from Code Space
S 16-Bit Instruction Word, 16-Bit Data Bus
S 16 x 16-Bit General-Purpose Working Registers
The device includes 80KB of flash memory and 2KB of data
SRAM. The MAXQ61C is a ROM version of this device.
S Memory Features
ꢀ80KB Flash Memory
ꢀ2KB Data SRAM
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 micro-
controller runs from a wide 1.70V to 3.6V operating voltage.
