Product details
Overview
R5F100EEANA#20 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 48 KB flash, 4 KB data flash, and 3 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (CSI, UART/LIN, I²C) for embedded control in battery-powered industrial sensors and smart home devices.
For engineers reviewing the R5F100EEANA#20 datasheet, R5F100EEANA#20 pinout, R5F100EEANA#20 application, or R5F100EEANA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm-pitch package, integrated data flash with 1M rewrite cycles, SNOOZE mode for low-latency wake-up, and support for LIN bus communication in automotive body electronics and appliance motor control.
Technical Context
The R5F100EEANA#20 implements the RL78 CPU core with a 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 integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction functions, and a watchdog timer powered by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 DMA channels enabling 2-clock transfers between SFR and RAM, and hardware multiplier/divider/MAC units for signed/unsigned 16×16→32-bit and 32÷32→32-bit operations - all optimized for deterministic real-time control in resource-constrained applications.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100EEANA#20?
The R5F100EEANA#20 operates at 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 under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time - enabling adaptive performance/power trade-offs in the R5F100EEANA#20.
Does the R5F100EEANA#20 support in-system programming and secure firmware updates?
Yes, the R5F100EEANA#20 supports self-programming with boot swap functionality and flash shield window protection. This allows safe field firmware updates by maintaining two independent flash banks - one active, one for new code - with atomic bank switching. The R5F100EEANA#20 also provides block-level erase prohibition to prevent unauthorized modification of protected code sections.
What analog features are integrated into the R5F100EEANA#20 for sensor interfacing?
The R5F100EEANA#20 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. These features enable direct connection of resistive, capacitive, or thermistor-based sensors without external references or signal conditioning - a key capability for compact, low-BOM designs using the R5F100EEANA#20.
How does the R5F100EEANA#20 manage power in battery-operated applications?
The R5F100EEANA#20 achieves industry-leading low-power operation: 66 μA/MHz in HALT mode, 0.57 μA in STOP mode with RTC and LVD active, and configurable SNOOZE mode for peripheral-triggered wake-up. Its wide 1.6–5.5 V supply range allows direct use with primary lithium or alkaline batteries, and the on-chip LVD provides programmable voltage monitoring across 14 levels - all essential for reliable long-life deployment of the R5F100EEANA#20.
Is the R5F100EEANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package (e.g., R5F100EAANA#20 through R5F100EHANA#20) share identical pinouts and electrical characteristics. This allows seamless migration between memory/configurations - for example, upgrading from R5F100EEANA#20 to R5F100FEANA#20 requires no PCB change, only firmware and BOM updates - preserving design investment across the R5F100EEANA#20 family.
