The MAXQ612/MAXQ622 provide integrated, low-cost
solutions that simplify the design of IR communications
equipment such as universal remote controls. Standard
features include the highly optimized, single-cycle,
MAXQ, 16-bit RISC core; 128KB of flash memory; 6KB
data RAM; soft stack; 16 general-purpose registers; and
three data pointers. The MAXQ core has the industry’s
best MIPS/mA rating, allowing developers to achieve
the same performance as competing microcontrollers at
substantially lower clock rates. Lower active-mode cur-
rent combined with the even lower MAXQ612/MAXQ622
stop-mode current results in increased battery life. IR
application-specific peripherals include flexible timers

General-Purpose, Digital, I/O, Type C Port. These port pins function as
bidirectional I/O pins. All port pins default to three-state mode after a
reset. All alternate functions must be enabled from software. Enabling
the pin’s special function disables the general-purpose I/O on the pin.
No Connection. Reserved for future use. Leave these pins unconnected.

for generating IR carrier frequencies and modulation. A
high-current, 25mA, IR drive pin and output pins capable
of sinking up to 5mA support IR applications. It also
includes a USB slave interface compatible with existing
host HID device drivers, I
to 56 general-purpose I/O pins ideal for keypad matrix
input, and a power-fail-detection circuit to notify.
Operating from DC to 12MHz, almost all instructions execute
in a single clock cycle (83.3ns at 12MHz), enabling nearly
12MIPS true-code operation. When active device opera-
tion is not required, an ultra-low-power stop mode can be
invoked from software, resulting in quiescent current con-
sumption of less than 300nA typical and 3FA maximum. The
combination of high-performance instructions and ultra-low
