Product details
Overview
R5F100EAGNA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100EAGNA#20 datasheet, R5F100EAGNA#20 pinout, R5F100EAGNA#20 application, or R5F100EAGNA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, industrial-grade -40°C to +105°C operation (G-grade), on-chip debug support, self-programmable flash with boot swap, and background data flash rewriting capability.
Technical Context
The R5F100EAGNA#20 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 integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, while peripheral control leverages DMA (2-channel), multiplier/divider/MAC units, and flexible I/O port configuration including N-ch open-drain outputs (6 V tolerant), TTL input buffers, and internal pull-up resistors - enabling direct interfacing with 1.8 V/2.5 V/3 V logic systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100EAGNA#20?
The R5F100EAGNA#20 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard test conditions with cache disabled. The R5F100EAGNA#20 achieves this throughput while maintaining ultra-low power consumption, making it suitable for real-time control tasks in resource-constrained environments.
Does the R5F100EAGNA#20 support in-system programming and secure flash protection?
Yes, the R5F100EAGNA#20 supports full in-system programming via on-chip debug interface and includes flash security features such as block erase/write prohibition and flash shield window functionality. These mechanisms prevent unauthorized access to firmware and enable secure bootloader implementations. The R5F100EAGNA#20 also supports boot swap for robust over-the-air updates without risk of bricking.
What are the supported low-power modes and their typical current consumption for the R5F100EAGNA#20?
The R5F100EAGNA#20 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, typical current is 0.57 μA at 25°C. HALT mode draws 66 μA/MHz during active operation. These values are specified in the official Renesas datasheet R01DS0131EJ0380 and confirmed for the G-grade industrial temperature range.
Can the R5F100EAGNA#20 interface directly with 1.8 V or 2.5 V peripherals?
Yes, the R5F100EAGNA#20 supports different-potential interface operation: its I/O ports can be configured for TTL input buffer compatibility and tolerate mixed-voltage signaling. When powered at 3.3 V or 5 V, it safely interfaces with 1.8 V/2.5 V devices without level shifters - verified in the "I/O Port" section of the R5F100EAGNA#20 datasheet and enabled by configurable input thresholds and drive strength settings.
Is the R5F100EAGNA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package - including R5F100EAGNA#20, R5F100EGGNA#20, and R5F101EAGNA#20 - share identical pinouts and mechanical footprints. This allows hardware reuse across memory/configurations, simplifying design scalability and migration paths within the same product family.
