전체 데이터 시트 (PDF, 604kB) English 다운로드 The MAXQ7665A–MAXQ7665D smart systems-on-a-chip (SoC) are data-acquisition systems based on a microcontroller (µC). As members of the MAXQ® family of 16-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 applications with minimal effort. The MAXQ7665A–MAXQ7665D incorporate a high-performance 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 temperature 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 programming 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.
