16-Bit Mixed-Signal Microcontroller
with LCD Interface

Detailed Description
The following sections are an introduction to the prima-
ry features of the microcontroller. More detailed
descriptions of the device features can be found in the
errata sheets and user’s guides described later in the
Additional Documentation section.
MAXQ Core Architecture
The MAXQ2010 is a low-cost, high-performance,
CMOS, fully static, 16-bit RISC microcontroller with
flash memory and an integrated LCD controller. The
MAXQ2010 supports up to a 160-segment LCD and
supports 8 channels of high-performance measurement
using a 12-bit successive approximation register (SAR)
ADC with internal reference. The MAXQ2010 is struc-
tured on a highly advanced, accumulator-based, 16-bit
RISC architecture. 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 microcontroller performing at up
to one million instructions-per-second (MIPS) for each
MHz of the system operating frequency.
A 16-level hardware stack, enabling fast subroutine
calling and task switching, supports the highly efficient
core. 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, eliminating the need
for software intervention. As a result, application speed
is greatly increased.
Instruction Set
The instruction set is composed of fixed-length, 16-bit
instructions that operate on registers and memory loca-
tions. The instruction set is highly orthogonal, allowing
arithmetic and logical operations to use any register
along with the accumulator. Special-function registers
control the peripherals and are subdivided into register
modules. The family architecture is modular so that new
devices and modules can reuse code developed for
existing products.
The architecture is transport-triggered, which means
that writes or reads from certain register locations can
also cause side effects to occur. These side effects
form the basis for the higher level op codes defined by
the assembler, such as ADDC, OR, JUMP, etc. The op
codes are actually implemented as MOVE instructions
between certain register locations, while the assembler
handles the encoding, which need not be a concern to
the programmer.
The 16-bit instruction word is designed for efficient exe-
cution. Bit 15 indicates the format for the source field of
the instruction. Bits 0 to 7 of the instruction represent
the source for the transfer. Depending on the value of
the format field, this can either be an immediate value
or a source register. If this field represents a register,
the lower four bits contain the module specifier and the
upper four bits contain the register index in that mod-
ule. Bits 8 to 14 represent the destination for the trans-
fer. This value always represents a destination register,
with the lower four bits containing the module specifier
and the upper three bits containing the register
subindex within that module. Any time that it is neces-
sary to directly select one of the upper 24 registers as a
destination, the prefix register (PFX) is needed to sup-
ply the extra destination bits. This prefix register write is
inserted automatically by the assembler and requires
only one additional execution cycle.
Memory Organization
The device incorporates several memory areas, includ-
ing:
4KB utility ROM
64KB of flash memory for program storage
2KB of SRAM for storage of temporary variables
16-level stack memory for storage of program return
addresses and general-purpose use
The incorporation of flash memory allows the devices to
be reprogrammed multiple times, allowing modifica-
tions to user applications post production. Additionally,
the flash can be used to store application information
including configuration data and log files.
The default memory organization is organized as a
Harvard architecture, with separate address spaces for
program and data memory. Pseudo-Von Neumann
memory organization is supported through the utility
ROM for applications that require dynamic program
modification and execution from RAM. The pseudo-Von
Neumann memory organization places the code, data,
and utility ROM memories into a single contiguous
memory map. See Figure 5 for the memory map.
Stack Memory
A 16-bit-wide hardware stack provides storage for pro-
gram return addresses and can also be used as gener-
al-purpose data storage. The stack is used
automatically by the processor when the CALL, RET,
and RETI instructions are executed and when an inter-
rupt is serviced. An application can also store values in
the stack explicitly by using the PUSH, POP, and POPI
instructions.
