RL78/G1A Smart Industrial Sensor Reference Microcontroller IO-Link - 1

RL78/G1A Smart Industrial Sensor Reference Microcontroller The Renesas Electronics’ RL78 is the microcontroller of choice for industrial sensor applications. It offers ultimate low power consumption ranked among the best in the industry. In addition to reduced current consumption down to 66 µA/MHz, the RL78/G1A offers multiple new features for IEC61131-9 IO-Link application support. These include ultra-small scale packages, up to 64 KB programmable flash memory with 1.8 V operating voltage, high accuracy 12-bit A/D converters, up to 32 MHz high speed on-chip oscillator with +/- 1% accuracy over temperature and voltage ranges. The RL78/G1A also features 4 KB on-chip Data Flash with background operation for IO-Link sensor data storage, numerous advanced safety features IEC or UL60730 compliant, an on-chip temperature sensor, 16-bit multi-function timers, and multiple high-speed serial communication channels for interfacing with sensor components. Two fully programmable DMA channels ensure high speed data transfer between peripherals without affecting the CPU load. Fully tested RL78 smart IO-Link Device stack with independent board support package for various IO-Link transceiver ICs, is available from Renesas alliance partner. The stack is designed according to IO-Link specification V1.1, including data storage, and more.
