The MAXQ7665A–MAXQ7665D smart systems-on-a-chip

(SoC) are data-acquisition systems based on a micro-

controller (µC). As members of the MAXQ

bit, reduced instruction set computing (RISC) µCs, 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 µCs 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 µC 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.
