Analog Devices ADuC706x Precision Analog Microcontrollers

The ADuC706x microcontroller family, from Analog Devices, Inc. (NYSE: ADI), offers best-in-class data conversion performance for hardware, firmware, and industrial systems engineers designing smart sensing, factory automation, and instrumentation equipment. The ADuC706x family of precision analog microcontrollers feature two 24-bit sigma-delta analog-to-digital converters (ADCs) and a host of analog peripherals with a 32-bit ARM7 core for precision sensing applications. The ADuC706x family is available in sample quantities and will be in full factory production in November 2008. The ADuC7060, ADuC7061 and ADuC7062 precision analog microcontrollers are priced at $4.90, $3.95 and $3.40 respectively, in 1,000-unit quantities.

Analog Devices (ADI) ADuC706x MicrocontrollersDesigned for 4-20 mA loop-powered applications in factory automation and for precision instruments, the ADuC706x family includes the ADuC7060, ADuC7061 and ADuC7062. The devices feature an industry-best ADC noise performance of just 60 nV — 20% better than the nearest competing part — and offer five times more processing power for a given clock rate.

In addition to the 24-bit sigma-delta ADCs and ARM7 core with eight interrupt priority levels, the new precision analog microcontrollers incorporate 32 Kbytes of flash memory and 4 Kbytes of SRAM, a programmable gain amplifier, multiplexers, buffers, an auxiliary 24-bit ADC for cold junction compensation and interfacing to thermocouple applications, and SPI (serial peripheral interface), UART (universal asynchronous receivers-transmitters) and I²C ports. The devices consume just 2.6 mA with all peripherals activated.

The ADuC7060, available in a 7 mm × 7 mm 48-pin chip-scale (QFN) package, offers more analog-input channels and general-purpose I/Os than other devices in the family. The ADuC7061 and ADuC7062 come in 5 mm × 5 mm 32-pin chip-scale (QFN) packages, ideal for space-constrained applications. The ADuC7062 does not include the auxiliary ADC channel.
