Product details
Overview
R5F100CEGLA#U0 from Renesas is a 32-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM in a 36-pin WFLGA (4 × 4 mm, 0.5-mm pitch) package, operating from 1.6 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates RTC, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100CEGLA#U0 datasheet, R5F100CEGLA#U0 pinout, R5F100CEGLA#U0 application, or R5F100CEGLA#U0 equivalent, key selection criteria include industrial-grade temperature support, on-chip data flash endurance (1M rewrite cycles), background operation during self-programming, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F100CEGLA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer, and DMA controller with 2/4 channels enabling 2-cycle transfers between SFR and RAM. The device supports BGO (background operation) for concurrent code execution during data flash rewriting.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100CEGLA#U0?
The R5F100CEGLA#U0 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs at this frequency, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling adaptive performance/power trade-offs in real-time applications.
Does the R5F100CEGLA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100CEGLA#U0 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for firmware security. Its self-programming capability - with boot swap function - allows safe dual-bank firmware updates without external programmers, ensuring field-upgrade integrity for R5F100CEGLA#U0 deployments.
How many analog input channels does the R5F100CEGLA#U0 support, and what is its ADC resolution?
The R5F100CEGLA#U0 integrates a 10-bit successive approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and temperature sensor, both selectable only in high-speed main mode. This enables precise ratiometric measurements and on-chip thermal monitoring without external components in R5F100CEGLA#U0-based designs.
What packaging and environmental specifications apply to the R5F100CEGLA#U0?
The R5F100CEGLA#U0 is supplied in a 36-pin WFLGA package (4 × 4 mm, 0.5-mm pitch) rated for industrial operation from –40°C to +105°C. It complies with RoHS and JEDEC J-STD-020 moisture sensitivity level (MSL) 3, making it suitable for automated SMT assembly and deployment in thermally demanding environments such as motor drives and outdoor utility equipment using R5F100CEGLA#U0.
Can the R5F100CEGLA#U0 operate from a single 1.8 V supply, and what are the implications?
Yes, the R5F100CEGLA#U0 supports operation from 1.6 V to 5.5 V, so it functions correctly at 1.8 V. At this voltage, maximum clock frequency is reduced per datasheet limits (typically ≤ 16 MHz), and some peripherals like high-speed UART may require adjustment. However, the 10-bit ADC, RTC, and STOP mode (0.57 μA) remain fully operational - enabling ultra-low-voltage battery-powered R5F100CEGLA#U0 applications.
