Detailed Description
The C arithmetic core of the MAXQ7665A–
MAXQ7665D is a 16-bit RISC machine with digital and
analog peripheral functions. They incorporate a 16-bit
RISC ALU with a Harvard memory architecture that can
address up to 128KB (64K x 16) of flash and 512 bytes
(256 x 16) of RAM memory. They also contain a hard-
ware multiplier, up to eight digital I/Os, a controller area
network (CAN 2.0B) bus, a JTAG interface, three
timers, an on-chip RC oscillator, a precision 12-bit
500ksps ADC with an 8-channel differential MUX and
PGA, a 12-bit precision DAC, an internal temperature
sensor and temperature-sensor driver, a linear regulator,
watchdog timer, and a dual power-supply supervisor.
The MAXQ offers a low < 3mA/MIPS ratio. The on-chip
16-bit x 16-bit hardware multiplier with accumulator,
performs single-cycle computations. Refer to the
MAXQ7665/MAXQ7666 User’s Guide for more detailed
information on configuring and programming the
MAXQ7665A–MAXQ7665D.
Analog Input Peripheral
The integrated 12-bit ADC employs an ultra-low-power,
high-precision, SAR-based conversion method and can
operate up to 500ksps (142ksps with PGA ≥ 2). The on-
chip 8-channel differential MUX and PGA allow the
ADC to measure eight fully differential analog inputs
with software-selectable input ranges through the PGA.
