ADuC7128/ADuC7129 is a precision analog microcontroller based on ARM7TDMI core with 12-bit ADC and DDS DAC
The ADuC7128 and ADuC7129 are fully integrated 12‑bit, 1 MSPS analog‑to‑digital converters with a built‑in 10‑bit DAC, ARM7TDMI core, and on‑chip Flash/EE memory. They operate from a 3.0 V to 3.6 V supply and are specified for an industrial temperature range of –40 °C to +125 °C.
The devices include multiple peripherals such as UART, I²C, SPI, PWM, quadrature encoder, comparator, and a programmable logic array. Detailed timing, pin‑out, and package information is provided for both 64‑lead LFCSP and 80‑lead LQFP options.
