The document describes the features of the ADuC816 MicroConverter® product. The product is a dual-channel 16-bit ADC with embedded Flash MCU functionality. It features high-resolution Sigma-Delta ADCs, programmable gain front end, and various built-in peripherals. Additionally, the product has on-chip memory, including 8 Kbytes of Flash/EE program memory and 640 bytes of Flash/EE data memory.
The ADuC816 is a complete smart transducer front-end integrating two high-resolution sigma-delta ADCs, an 8-bit 8051-based MCU, and nonvolatile Flash/EE memory on a single chip. It is designed for intelligent sensors, weigh scales, and portable instrumentation applications.
The device operates from a single 3 V or 5 V supply and features 8 Kbytes of on-chip Flash/EE program memory, 640 bytes of Flash/EE data memory, and 256 bytes of RAM. It includes an 8051-compatible instruction set running at up to 12.58 MHz, driven by a 32 kHz external crystal and an on-chip PLL.
