Detailed Description
The MAXQ7670A incorporates a 16-bit RISC arithmetic
logic unit (ALU) with a Harvard memory architecture
that addresses 64KB (32K x 16) of flash and 2048
bytes (1024 x 16) of RAM memory. This core combined
with digital and analog peripherals provide versatile
data-acquisition functions. The peripherals include up to
seven digital I/Os, a 4-wire SPI interface, a CAN 2.0B
bus, a JTAG interface, a timer, an integrated RC oscilla-
tor, two linear regulators, a watchdog timer, three
power-supply supervisors, a 12-bit 125ksps SAR ADC
with programmable-gain amplifier (PGA) and eight sin-
gle-ended or four differential multiplexed inputs. The
power-efficient MAXQ20 C core consumes less than
1mA/MIPS. Refer to the
MAXQ7670 User’s Guide for
more detailed information on configuring and program-
ming the MAXQ7670A.
Analog Input Peripheral
The integrated 12-bit ADC employs an ultra-low-power
SAR-based conversion method and operates up to
125ksps with PGA = 1V/V (75.5ksps with PGA = 16V/V).
The integrated 8-channel multiplexer (mux) and PGA
allow the ADC to measure eight single-ended (relative
to AGND) or four fully differential analog inputs with
software-selectable input ranges through the PGA. See
Figures 3 and 4.
