Analog Devices ADuC7128/ADuC7129 Microcontroller User Manual
The ADuC7128/ADuC7129 are fully integrated 12‑bit, 1 MSPS data‑acquisition microcontrollers that combine an ARM7TDMI core, multi‑channel ADC, DDS‑based DAC, and on‑chip Flash/EE memory. The document details the device architecture, pin functions, and electrical characteristics.
Key sections cover functional block diagrams, timing specifications, power‑supply monitoring, peripheral interfaces (UART, SPI, I²C, PWM, quadrature encoder), memory organization, and development tools. The handbook also includes design recommendations, ordering information, and mechanical dimensions.
