Detailed Description
The 16-bit RISC core (MAXQ20) of the MAXQ7666 con-
trols the analog and digital peripheral functions. The
16-bit RISC ALU addresses 16KB (8K x 16) program
flash, up to 512 bytes (256 x 16) data flash and 512
bytes (256 x 16) of RAM memory with Harvard memory
architecture. The MAXQ7666 peripheral components
include a precision 12-bit 500ksps ADC with an 8-chan-
nel differential mux and PGA, a 12-bit precision DAC,
an internal temperature sensor, an external tempera-
ture-sensor driver, a hardware multiplier, eight digital
I/Os, a controller area network (CAN 2.0B) bus, a JTAG
interface, and three type-2 timers. An internal 7.6MHz
RC oscillator or a crystal oscillator driving an external
crystal of 8MHz provide the system clock. The device
also includes a +3.3V linear regulator, watchdog timer,
and two power-supply supervisors.
The MAXQ20 offers a low < 3mA/MIPS ratio. The inte-
grated 16-bit x 16-bit hardware multiplier with accumu-
lator performs single-cycle computations. Refer to the
MAXQ7665/MAXQ7666 User’s Guide for more detailed
information on configuring and programming the
MAXQ7666.
Analog Input Peripheral
The integrated 12-bit ADC employs an ultra-low-power,
high-precision, SAR-based conversion method and
operates up to 500ksps (142ksps with PGA
≥ 2). The
ADC measures eight fully differential multiplexed ana-
log inputs with software-selectable input ranges
through a PGA. See Figure 1.
