General Description
The MAXQ7670A is a highly integrated solution for mea-
suring multiple analog signals and outputting the results
on a control area network (CAN) bus. The device oper-
ates from a single 5V supply and incorporates a high-
performance, 16-bit reduced instruction set computing
(RISC) core, a SAR ADC, and a CAN 2.0B controller,
supporting transfer rates up to 1Mbps. The 12-bit SAR
ADC includes an amplifier with programmable gains of
1V/V or 16V/V, 8 input channels, and conversion rates up
to 125ksps. The eight single-ended ADC inputs can be
configured as four unipolar or bipolar, fully differential
inputs. For single-supply operation, the external 5V sup-
ply powers the digital I/Os and two separate integrated
linear regulators that supply the 2.5V digital core and the
3.3V analog circuitry. Each supply rail has a dedicated
power-supply supervisor that provides brownout detec-
tion and power-on reset (POR) functions. The 16-bit RISC
microcontroller (C) includes 64KB (32K x 16) of non-
volatile program/data flash and 2KB (1K x 16) of data
RAM. Other features of the MAXQ7670A include a 4-wire
SPI interface, a JTAG interface for in-system program-
ming and debugging, an integrated 15MHz RC oscilla-
tor, external crystal oscillator support, a timer/counter
with pulse-width modulation (PWM) capability, and seven
GPIO pins with interrupt and wake-up capability.
The system-on-a-chip (SoC) MAXQ7670A is a C-
based, smart data acquisition system. As a member of
the MAXQ family of 16-bit, RISC Cs, the MAXQ7670A
is ideal for low-cost, low-power, embedded-applica-
tions such as automotive, industrial controls, and build-
ing automation. The flexible, modular architecture used
in the MAXQ Cs allows development of targeted prod-
ucts for specific applications with minimal effort.
The MAXQ7670A is available in a 40-pin, 5mm x 5mm
TQFN package, and is specified to operate over the -40°C
to +125°C automotive temperature range.
