MCUs with integrated LCD controllers

5 September 2012 DSP, Micros & Memory

Renesas Electronics has premiered the RL78/L12 group of low-power microcontrollers (MCUs) with on-chip liquid crystal display (LCD) controller that reduce current consumption by approximately 30% compared to earlier Renesas products.

The new 16-bit MCUs are designed for products equipped with small LCD panels, including portable household appliances, healthcare devices, building management systems and industrial applications that require improved user interfaces and low power.

The product family consists of 18 product versions with pin count ranging from 32 to 64 pins, and on-chip Flash memory capacities ranging from 8 KB to 32 KB. They consume as little as 66 μA/MHz and can achieve a mere 0,57 μA while operating the real-time clock with full calendar function, low-voltage detection circuit and maintaining 100% of RAM contents.

In addition, the MCUs feature a mode that halts the internal LCD-related operations of the MCU when the multi-segment LCD display is not in use, further reducing current consumption and boosting power efficiency.

The devices support up to 280 LCD segments (64-pin models) in 35 x 8 configuration and can operate from 1,6 V to 5,5 V power supply. The LCD controller provides three methods of generating LCD drive voltage – internal voltage boost, capacitor split and external resistance division.
