• Manufacturer Part Number: MAXQ3100-EMN+
• Description: Mixed-Signal Microcontroller with Analog Comparators, LCD, and RTC
• Manufacturer: MAXIM [Maxim Integrated Products]

The following is an introduction to the primary features
of the microcontroller. More detailed descriptions of the
device features can be found in the data sheets, errata
sheets, and user’s guides described later in the
Additional Documentation section.
The MAXQ3100 is a high-performance, CMOS, 16-bit
RISC microcontroller with EEPROM and an integrated
160-segment LCD controller. It is structured on a highly
advanced, accumulator-based, 16-bit RISC architec-
ture. Fetch and execution operations are completed in
one cycle without pipelining, because the instruction

contains both the op code and data. The result is a
streamlined 4.194 million instructions-per-second
(MIPS) microcontroller.
The highly efficient core is supported by a 16-level
hardware stack, enabling fast subroutine calling and
task switching. Data can be quickly and efficiently
manipulated with three internal data pointers. Multiple
data pointers allow more than one function to access
data memory without having to save and restore data
pointers each time. The data pointers can automatically
increment or decrement following an operation, elimi-
nating the need for software intervention. As a result,
the application speed is greatly increased.
