16bit MCUs for auto body control systems

A range of low power 16bit MCUs from Renesas is targeted at vehicle control systems. Called the RL78/F15 group and featuring 36 variants, the high functionality devices are said to combine low power consumption with high processing performance and CAN communications.

Fully compatible with the RL78/F13 and RL78/F14 groups, the RL78/F15 products include a device supplied in a 144pin package. According to the company, devices with 48pins and more come with up to 512kbyte of flash. When combined with the RL78/F13 and RL78/F14 groups, there will be 127 product variants, with pin counts ranging from 20 to 144pins.

Designed around Renesas’s RL78 core running at up to 32MHz, the parts have two CAN channels, allowing independent control and diagnostics links. There are up to three hardware LIN channels and support for the Inter Equipment Bus (IEbus), which is said to make it possible to accommodate car audio applications in the vehicle information field.

Although designed for use in temperatures ranging from -40 to 105°C, Renesas says the upper limit can be extended to 125°C by reducing the maximum clock frequency to 24MHz.
