16-Bit Microcontroller with Infrared Module
MAXQ610
♦ Dedicated Pointer for Direct Read from Code
General Description
Space
®
The MAXQ610 is a low-power, 16-bit MAXQ micro-
controller designed for low-power applications includ-
ing universal remote controls, consumer electronics,
and white goods. The MAXQ610 combines a powerful
16-bit RISC microcontroller and integrated peripherals
including two USARTs and an SPI™ master/slave com-
munications port, along with an IR module with carrier
frequency generation and flexible port I/O capable of
multiplexed keypad control.
♦ 16-Bit Instruction Word, 16-Bit Data Bus
♦ 16 x 16-Bit General-Purpose Working Registers
♦ Secure MMU for Application Partitioning and IP
Protection
♦ Memory Features
64KB Flash:
512 Byte Sectors
The MAXQ610 includes 64KB of flash memory and 2KB
of data SRAM. Intellectual property (IP) protection 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 MAXQ610, while limiting access to only
data and code allowed by their privilege level.
20,000 Erase/Write Cycles per Sector
Masked ROM Available
2KB Data SRAM
♦ Additional Peripherals
Power-Fail Warning
Power-On Reset/Brownout Reset
Automatic IR Carrier Frequency Generation and
Modulation
Two 16-Bit, Programmable Timers/Counters with
Prescaler and Capture/Compare
SPI and Two USART Communication Ports
Programmable Watchdog Timer
8kHz Nanopower Ring Oscillator Wake-Up Timer
Up to 24 (MAXQ610A) or 32 (MAXQ610B)
General-Purpose I/Os
For the ultimate in low-power battery-operated perfor-
mance, the MAXQ610 includes an ultra-low-power stop
mode (0.2µA, typ). In this mode, the minimum amount
of circuitry is powered. Wake-up sources include exter-
nal interrupts, the power-fail interrupt, and a timer inter-
rupt. The microcontroller runs from a wide 1.70V to 3.6V
operating voltage.
