Product details
Overview
R5F100CEALA#W0 from Renesas is a 36-pin, 64 KB flash, 4 KB data flash, 4 KB RAM RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V operation, and integrated 10-bit ADC (26-channel), RTC, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100CEALA#W0 datasheet, R5F100CEALA#W0 pinout, R5F100CEALA#W0 application, or R5F100CEALA#W0 equivalent, key selection criteria include its WFLGA-36 package, -40°C to +85°C industrial temperature grade (A-grade), on-chip debug support, background data flash rewriting capability, and 32 MHz max CPU clock with high-accuracy ±1.0% on-chip oscillator.
Technical Context
The R5F100CEALA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features an address space of 1 MB. It integrates dual-power domain I/O capable of interfacing with 1.8/2.5/3.0 V peripherals without level shifters.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar RTC with alarm and correction, one watchdog timer, and three serial interface types (CSI, UART/LIN, I²C) - all configurable via dedicated SFRs and supported by DMA channels for zero-CPU-overhead transfers between SFRs and RAM.

FAQ
What is the operating temperature range for the R5F100CEALA#W0?
The R5F100CEALA#W0 is rated for industrial operation from –40°C to +85°C. This A-grade specification ensures reliable performance in factory automation, outdoor metering, and HVAC environments where ambient thermal stress exceeds consumer-grade limits. The device maintains full functionality across this range, including ADC accuracy and oscillator stability.
Does the R5F100CEALA#W0 support in-circuit debugging?
Yes, the R5F100CEALA#W0 includes full on-chip debug functionality accessible via the TOOLRxD/TOOLRST pins. It supports breakpoints, watchpoints, and real-time variable inspection using Renesas E2 studio and CS+ IDEs. Debug communication operates at standard UART baud rates without requiring additional debug hardware beyond a USB-to-UART bridge.
Can the R5F100CEALA#W0 operate from a single 1.8 V supply?
No - the R5F100CEALA#W0 requires a minimum VDD of 1.6 V but is not specified to operate reliably at 1.8 V alone due to its 32 MHz maximum clock requirement. At 1.8 V, the maximum allowed frequency is 16 MHz per the datasheet's voltage-frequency curve. For full-speed operation, ≥2.7 V is recommended; 1.8 V is viable only for low-frequency, ultra-low-power STOP/HALT use cases.
How many serial communication interfaces does the R5F100CEALA#W0 provide?
The R5F100CEALA#W0 provides up to three serial interface types: two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels. On the 36-pin WFLGA package, it supports at least two UARTs, three I²C ports, and two CSI modules - enabling concurrent communication with displays, sensors, and wireless transceivers.
Is the R5F100CEALA#W0 pin-compatible with other RL78/G13 variants in the same package?
Yes - all RL78/G13 devices in the 36-pin WFLGA package (e.g., R5F100CAALA#W0, R5F100CEALA#W0, R5F100CGALA#W0) share identical pinouts and electrical characteristics. Firmware and PCB layouts designed for one variant can be reused across others in the same memory/feature subset, provided peripheral initialization matches the target part's resource allocation.
