Microcontroller with Analog Comparator
and LED Driver
General Description
The MAXQ3212 microcontroller is a low-power, 16-bit
RISC device that incorporates an analog comparator
and a high-current I/O pin for directly driving an LED.
The device is uniquely suited for cost-conscious appli-
cations such as battery-powered devices, system moni-
tors, and white goods, but can be used in any
application that requires high performance and low-
power operation. The high-performance 16-bit
RISC MAXQ
®
core and 8-bit accumulators are comple-
mented by standard amenities such as timers and digi-
tal I/O. The power consumption per MIPS ratio is
among the best in the 16-bit microcontroller industry.

/P0.4
Voltage Reference Input/Output or General-Purpose, Digital I/O, Type D Port.
This pin functions as either
the output of the internal voltage reference or as a bidirectional I/O. This pin can also be driven with an external
voltage to provide an optional voltage reference. The pin defaults to a digital input with a weak pullup after a
reset.
Analog Voltage Comparator Output or General-Purpose, Digital I/O, Type D Port.
This pin functions as
either the output of the analog voltage comparator or as a bidirectional I/O. The pin defaults to a digital input
with a weak pullup after a reset.
Timer 2 Input/Output or General-Purpose, Digital I/O, Type D Port.
This pin functions as either the input or
output of Timer 2 or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup after a reset.
Secondary Timer 2 Input/Output or General-Purpose, Digital I/O, Type D Port.
This pin functions as either
the secondary output of Timer 2 or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup
after a reset.
General-Purpose, Digital I/O, Type D Port.
This pin functions as a bidirectional I/O, and defaults to a digital
input with a weak pullup after a reset.
General-Purpose, Digital I/O, Type D Port.
This pin functions as a bidirectional I/O, and defaults to a digital
input with a weak pullup after a reset.
General-Purpose, Digital I/O, Type D Port.
This pin functions as a bidirectional I/O, and defaults to a digital
input with a weak pullup after a reset.
Debug Port Signal TDO or General-Purpose, Digital I/O, Type D Port.
This pin functions as either the TDO
signal of the debug port or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup after a reset.
Debug Port Signal TCK or General-Purpose, Digital I/O, Type D Port.
This pin functions as either the TCK signal
of the debug port or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup after a reset.
Oscillator Input.
Connect an external crystal or resonator between HFXIN and HFXOUT for system clock
generation. When using a crystal, a load capacitor of approximately 22pF must be connected between this pin
and ground. Alternatively, HFXIN is the input for an external clock source when HFXOUT is floating.
