General Description
The MAXQ7665A–MAXQ7665D smart systems-on-a-chip
(SoC) are data-acquisition systems based on a micro-
controller (C). As members of the MAXQ family of 16-
bit, reduced instruction set computing (RISC) Cs, the
MAXQ7665A–MAXQ7665D are ideal for low-cost, low-
power, embedded applications such as automotive,
industrial controls, and building automation. The flexible,
modular architecture design used in these Cs allows
development of targeted products for specific applica-
tions with minimal effort.
The MAXQ7665A–MAXQ7665D incorporate a high-per-
formance 16-bit RISC core, a 12-bit 500ksps SAR ADC
with a programmable gain amplifier (PGA), and a full
CAN 2.0B controller supporting transfer rates up to
1Mbps. These devices include a 12-bit DAC with a
buffered voltage output and on-chip oscillator circuitry
to operate from an external high frequency (8MHz)
crystal. There is also a built-in internal RC oscillator as
an alternative to using an external crystal. The
MAXQ7665A–MAXQ7665D contain an internal tempera-
ture sensor to measure die temperature and a remote
temperature-sensor driver. The analog functions and
digital I/O are powered from a +5V supply, while the
internal digital core is powered from +3.3V, which can
be supplied by an on-chip linear regulator. These
devices also include a dual power-supply supervisor
with reset and a JTAG interface for in-system program-
ming and debugging. The 16-bit RISC C includes up
to 128KB (64K x 16) of flash memory and 512 bytes
(256 x 16) of RAM.
The MAXQ7665A–MAXQ7665D are available in a 7mm x
7mm 48-pin TQFN package and are specified to operate
from -40°C to +125°C.
