Analog Devices introduces precision data converter portfolio for integrated control of optical transmitters
March 29, 2004 San Francisco--By embedding precision analog functionality with digital programming on a single chip, Analog Devices aims to simplify control and monitoring in applications such as optical network transmitters, factory automation sensors, and automotive body control electronics. The new ADuC702x precision analog microcontroller family featuring ARM7-based programmability joins Analog Devices' portfolio of 8052-based solutions, known as the MicroConverter series. The new portfolio was announced at electronicaUSA and the Embedded Systems Conference held here this week.
Analog Devices' precision analog microcontroller solution integrates a powerful 32-bit RISC (reduced instruction set computer) core with precision data conversion technology that supports up to 16 channels of fast, 12-bit accurate analog-to-digital conversion and up to four 12-bit digital-to-analog converters. The ADuC702x precision analog microcontroller family featuring ARM7-based programmability joins Analog Devices' portfolio of 8052-based solutions, known as the MicroConverter series. Like the ARM7 core family-based range of products, MicroConverter products are designed for high-precision measurement and control, and data acquisition systems with basic digital programming needs.
"We are seeing strong customer demand for high performance data converters with embedded processing power," said Mike Britchfield, product line director for precision converters, Analog Devices. "As performance, size, and power requirements are becoming more stringent, customers are moving toward integrated products including precision converters and powerful MCUs such as the ARM7 family core."
The ADuC702x solutions integrate an ARM7TDMI core that features a flash-based 16-/32-bit RISC MCU with processing capability up to 45 MIPS peak performance. Analog peripherals include up to 16 channels of fast, 12-bit accurate analog-to-digital conversion, up to four individual 12-bit monotonic DACs (digital-to-analog converters) and a precision bandgap reference with a drift performance of better than 10 ppm/ºC. Other peripherals include a comparator, programmable logic array, and 3-phase PWM generator. The devices also support flexible power-down and wake-up modes and are specified for 3-V operation with a temperature range of -40º to +85ºC, +105ºC, and +125ºC. Packaging options range from a tiny 6 mm x 6 mm 40-lead chip-scale package (CSP) to an 80-pin LQFP.
Factory automation equipment, utilizing ultrasonic, magnetic or optical proximity sensors, benefits from the integration of precision analog with a powerful processing core in a small package. The ADuC702x family offers an integrated monitoring and control solution for SFP and XFP optical transceivers. By including support for LIN, the ADuC702x family offers solutions for body-control electronics in automobiles. To further support the automotive market, future derivatives will integrate CAN and additional memory.
Analog Devices' low-cost QuickStart Development System includes a suite of comprehensive software development tools by KEIL Software and IAR Systems. These are shipped along with supporting hardware, such as evaluation board, JTAG emulator, power supply and cables.
Pricing and availability
Pricing for 1,000-piece quantities starts at $4.55 for one of the 40-Lead CSP options and ranges up to $12.80 for the full-featured ADuC7026 in an 80-pin LQFP. QuickStart Development Systems and sample parts are currently available and will be released to production in October 2004. The QuickStart Development System is priced at $249 and is available directly from Analog Devices. For more information, please visit:
