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. Processing Power, Peripherals and Tiny Packages The new ADuC702x solutions integrate an ARM7TDMI® core that features a flash-based 16-/32-bit RISC (reduced instruction set computer) 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/degrees C. Other peripherals include a comparator, PLA (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 –40 degrees C to +85 degrees C, +105 degrees C, and +125 degrees C. Packaging options range from a tiny 6 mm x 6 mm 40-lead CSP (chip-scale package) to an 80 pin LQFP. 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.
