Renesas introduces low-power LCD microcontrollers for sensor modules and healthcare equipment

Renesas Electronics has expanded its RL78 Series of microcontrollers (MCUs) with 40 new RL78/L1C devices that integrate LCD display functions, USB functions, and 12-bit A/D converters on a single chip. The new RL78/L1C MCUs can interface to a wide range of sensors such as pressure, temperature, and proximity sensors, and are suitable for portable monitors and mobile healthcare applications, such as blood pressure and blood glucose monitoring equipment.

Comprising 40 products, the new RL78/L1C Group controls segment display type LCD panels and is available in 80- and 100-pin packages with on-chip flash memory capacities ranging from 64 to 256 kilobytes (KB).

The use of sensor modules in manufacturing equipment and consumer healthcare devices to increase system functionality and intelligence continues to grow. This results in an increasing need to support the communication of data acquired by the manufacturing and consumer equipment so that the measurement results can be managed on host equipment and personal computers.

Healthcare equipment such as blood pressure and glucose meters are becoming more widely used in homes, driving greater demand for devices that are easy and convenient to use at home, offer longer battery life, and are cost effective. Renesas addresses these needs with the new RL78/L1C MCUs featuring an on-chip USB function module and 12-bit A/D converter, contributing to lower system costs and reduced power consumption.
