The document provides information about the features and characteristics of the ADuC7124/ADuC7126 Precision Analog Microcontroller. The product offers 12-bit analog input/output, large memory, ARM7TDMI MCU, and an enhanced IRQ handler.
The ADuC7124 and ADuC7126 are fully integrated 12‑bit analog microcontrollers that combine high‑performance multichannel ADCs, a 16‑bit/32‑bit ARM7TDMI core, Flash/EE memory, and a range of on‑chip peripherals. They target industrial control, smart sensors, precision instrumentation, base‑station systems, and patient monitoring applications.
The handbook details the devices' functional blocks, pin configurations, timing specifications, and electrical characteristics, including ADC/DAC performance, power‑supply requirements, and programmable logic array features. It also covers programming, in‑circuit download, and development tools.
