Precision Data Converters Mate With ARM7 Core May 2004 Issue Published Date: May 03, 2004
Focussing on industrial, optical networking, and automotive applications, the ADuC702x analog microcontroller family pairs a 12-bit analog front end with an ARM7TDMI core that features a flash-based 16-/32-bit RISC MCU. The devices provide up to 16 channels of 12-bit a/d conversion, up to four 12-bit d/a converters, and a precision bandgap reference with a drift performance of better than 10 ppm/°C. Other peripherals include a comparator, PLA, and a three-phase PWM generator. The devices operate on 3V and, depending on the option, in temperatures from –40°C to +85°C, +105°C, and +125°C. Packaging options range from a 40-lead CSP to an 80-pin LQFP. Prices span $4.55 to $12.80 each/1,000. A support package, the QuickStart Development System, is available for $249.
