‘electronicaUSA with ESC’: Analog Devices introduces precision MCU

San Francisco, CA— Aiming to simplify control and monitoring for industrial, optical networking and automotive applications, Analog Devices Inc. (ADI) introduced its ADuC702x pre-cision analog microcontroller family at “ electronicaUSA with Embedded Systems Conference ” (ESC) on March 29 at the Moscone Center. The new microcontroller (MCU) solution embeds precision analog functionality along with digital programming on one chip.

ADuC702x integrates an ARM7 core, featuring a flash-based, 16-/32-bit RISC (reduced instruction set computer) MCU, with processing capability up to 45 MIPS peak. Analog peripherals include up to 16 channels of fast, 12-bit accurate A/D conversion; up to four individual 12-bit monotonic D/A converters; and a precision bandgap reference (drift performance better than 10 ppm/°C. A comparator, programmable-logic array (PLA), and three-phase pulse-width modulation (PWM) generator make up the devices’ other peripherals.

These devices also support flexible power-down and wake-up modes and are specified for 3-V operation with a temperature range of -40 to 85 °C, or up to 105 °C and 125 °C, depending on the model. Packaging options range from a tiny 6 x 6 mm 40-lead CSP (chip-scale package) to an 80-pin LQFP (low-profile, quad flat package).

Example applications for the new MCU family include ultrasonic, magnetic or optical proximity sensors used in factory automation equipment; integrated monitoring and control of SFP and XFP optical transceivers; and “solutions for body-control electronics in automobiles,” says ADI. “To further support the automotive market, future derivatives [of ADuC702x] will integrate CAN and additional memory.”

Tools, availability Development tools complement the ADuC702x family. ADI’s QuickStart Development System includes a comprehensive suite of software development tools by KEIL Software and IAR Systems. The tools come with supporting hardware, such as evaluation board, JTAG emulator, power supply, and cables. Pricing for 1,000-piece quantities of the CSP option starts at $4.55 each; and the full-featured ADuC7026 in LQFP version costs $12.80 each. QuickStart Develop-ment System (priced at $249) and sample parts are available now. Release to production is slated for October 2004.
