APPLICATIONS
The low-power, high-performance RISC architecture of the DS2790 makes it an excellent fit for many portable or
battery-powered applications that require cost-effective computing and analog measurement capability. The high-
throughput core is programmable in-circuit over the 2-wire and JTAG interfaces, allowing for firmware upgrades,
and ease of code development. Applications benefit from a wide range of peripheral interfaces, allowing the
microcontroller to communicate with many external devices. With an integrated charge pump, high side N-FET
drivers, and ADC’s capable of measuring cell voltage, and monitoring current. The DS2790’s high level of
integration reduces component count and board space, critical factors in the design of portable systems.
The DS2790 is ideally suited for applications such as fuel gauging, sensor conditioning, and data collection.
