Renesas Electronics RX111 32-bit Microcontrollers
Renesas Electronics RX111 32-bit Microcontrollers are offered in pin counts of 36 to 64 pins, with a flash memory capacity of 16KB to 512KB and RAM capacity of 8KB to 64KB. With USB 2.0 for Battery Charging (BC 2.0), low consumption current, and fast wakeup from standby, these microcontrollers are suitable for use in computer peripherals and healthcare and wearable devices. With their three-phase motor control timers, the RX111 MCUs are also suitable for motor control applications in home appliances and industrial equipment.
The RX111 MCUs are ideal for any wireless implementation. With enhanced digital signal processing (DSP) capabilities and performance up to 50 DMIPs, these devices have the performance needed for Cloud-based Wi-Fi® applications. And, with efficient, True Low-Power (100µA/MHz) operation and ultra-low-power standby modes (as low as 350nA), the RX111 MCUs can also maximize battery life in battery-powered BLUETOOTH® Low Energy (BLE) and Low-Power Wide-Area (LPWA) wireless applications.
