Key Features

  • 16-bit RL78 core running at up to 32 MHz delivers efficient signal processing and control performance in a low-power microcontroller architecture
  • 64 kB on-chip flash memory with integrated data flash enables firmware storage and non-volatile parameter retention without external memory
  • 64-pin QFN package with a small footprint suits compact PCB designs in space-constrained embedded control and IoT sensor node applications

Applications

The R5F10FLEANA is suited for low-power embedded control applications including home appliances, industrial sensor nodes, and building automation controllers where a 16-bit RL78 core at 32 MHz provides sufficient computing performance with minimal power consumption. Its 64 kB flash and 64-pin QFN package make it a practical choice for compact control boards in HVAC systems, smart meters, and motor control units. Renesas RL78 peripherals such as multiple UART, SPI, and I2C interfaces enable versatile connectivity for sensor fusion and communication tasks in battery-operated or always-on embedded designs.

Frequently Asked Questions

What CPU speed and flash capacity does the R5F10FLEANA offer for embedded firmware development?

The R5F10FLEANA operates the RL78 16-bit core at up to 32 MHz and provides 64 kB of on-chip flash memory for program storage. This combination allows developers to run moderately complex control algorithms, communication stacks, and state machines within the device, making it appropriate for applications such as smart appliance controllers, industrial sensor nodes, and motor drive systems that require more than a basic 8-bit microcontroller but do not need a full 32-bit core.

How does the 64-pin QFN package of the R5F10FLEANA affect PCB layout and I/O availability?

The 64-pin QFN package provides up to 64 pins in a compact no-lead format with a smaller PCB footprint than equivalent LQFP packages of the same pin count. The thermal pad on the bottom of the QFN also aids heat dissipation compared to leaded packages. With 64 pins available, the R5F10FLEANA offers a rich set of GPIO, analog inputs, and serial communication interfaces, supporting designs that need multiple 12-bit ADC channels, UART ports, and timer outputs simultaneously.

In which low-power scenarios does the RL78 architecture of the R5F10FLEANA provide a design advantage over 32-bit alternatives?

The RL78 architecture is optimized for low-power operation with multiple sleep modes and a supply voltage range that typically extends down to 1.8 V, making the R5F10FLEANA well suited for battery-powered applications such as wireless sensor nodes, portable meters, and remote controls where the MCU must operate for months or years on a small battery. In these scenarios, the RL78's efficient 16-bit instruction set and hardware low-power modes can achieve active current consumption in the low mA range and standby current in the low µA range, which a general-purpose 32-bit Cortex-M core often cannot match at the same cost point.
