The R8C/LA3A and LA5A groups are available in low-profile quad flat packages (LQFP) with in 32 pins (7mm x 7mm) and 52 pins ( 10mm x 10mm) which offer minimum for the Liquid Crystal Display (LCD) capability up to 24 segments x 4 common. Segments or IO ports are software selectable by every single port and provide flexible port usability with the smallest pin counts of Renesas Electronics’ family of MCUs with an LCD controller.
In addition to the combination of different pin counts and an LCD controller, the R8C/LAxA groups offer energy efficient features contributing to reduced overall system power consumption for longer battery life. Renesas Electronics’ first 1.8V E/W Flash memory, including the data flash area and code area, enables users to program the systems in the fields even at the end of the system’s life. The A/D conversion, which is also available from 5.5V down to 1.8V, broadens the operating range, especially for sensor applications. Along with the lower operating voltage range, the R8C/LAxA groups offer special power down modes to minimize power consumption while the system is idle.
The key differences between the two groups are listed in the table below. A variety of specifications is available with different pin counts and supported LCD sizes, allowing customers to choose the version that best matches their requirements.
