Description

The RL78/I1E microcontroller is an intelligent, flexible analog MCU suitable for countless industrial and medical sensing applications such as flow measurement, strain gauges, pressure or temperature sensing. With enhanced analog features such as configurable op-amps with programmable gain, supporting inverting, non-inverting topologies, or instrumentation amplifiers, the RL78/I1E can be a platform for different types of sensors. The RL78/I1E features a 24-bit delta-sigma A/D, and a separate 10-bit A/D block, with a 12-bit D/A. The package lineup for RL78/I1E MCU goes down to 4 mm x 4 mm or 5 mm x 5 mm reducing PCB footprint. Operating temperature up to 125°C makes it an ideal solution for the harshest of environments.
