Product details
Overview
R5F10EGAANA#20 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G1A microcontroller with 16 KB flash, 4 KB data flash, 2 KB RAM, 12-bit ADC (24 channels), and ultra-low-power operation down to 0.57 µA in RTC+LVD halt mode. It integrates UART, I²C, SPI, RTC, programmable buzzer outputs, and operates from 1.6 V to 3.6 V - ideal for battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F10EGAANA#20 datasheet, R5F10EGAANA#20 pinout, R5F10EGAANA#20 application, or R5F10EGAANA#20 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm) package, industrial-grade −40 °C to +105 °C temperature rating, 32 MHz max CPU frequency delivering 41 DMIPS, and support for on-chip debug via TOOL0/TOOLRxD/TOOLTxD pins.
Technical Context
The R5F10EGAANA#20 implements the RL78 16-bit CISC core with 3-stage Harvard pipeline, enabling 86% of instructions in 1–2 clock cycles. Its peripheral set includes dual serial array units supporting up to six total I²C/SPI/UART interfaces, eight 16-bit timer channels, and hardware CRC for IEC 60730 compliance.
It features dual power domains (VDD/EVDD0, VSS/EVSS0) for noise-sensitive analog operation, a high-speed on-chip oscillator (±1% accuracy at 32 MHz over voltage/temperature), and flexible pin remapping via the Peripheral I/O Redirection Register (PIOR) - allowing dynamic assignment of functions like KR0–KR5, SDA/SCL, or TI/TO across multiple ports.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10EGCGNA#20 | Same package and pinout; 32 KB flash, 3 KB RAM (vs. 16 KB/2 KB) | Better suited for applications requiring larger firmware image or more runtime variables (e.g., BLE stack integration) | Select when firmware size exceeds 16 KB or additional RAM buffers are needed for communication protocols |
| R5F10EBDANA#20 | 32-pin HWQFN (5 × 5 mm); 48 KB flash, 2 KB RAM, same peripherals but fewer I/O (26 vs. 42) | Preferred for space-constrained designs where I/O count and ADC channels can be reduced | Choose for compact PCB layouts where 48-pin footprint is prohibitive and 24 ADC channels are not required |
Compared with R5F10EGCGNA#20 and R5F10EBDANA#20, the R5F10EGAANA#20 offers optimal balance of industrial temperature range, 48-pin I/O scalability, and cost-efficient 16 KB flash - making it ideal for mid-tier embedded control where memory headroom and package size must both be tightly managed.

FAQ
What is the operating temperature range of the R5F10EGAANA#20?
The R5F10EGAANA#20 is rated for industrial operation from −40 °C to +105 °C, as indicated by the 'G' suffix in its part number. This specification is validated per Renesas' electrical characteristics testing under TA = −40 to +105 °C conditions and applies to all core, analog, and I/O functionality - including the 12-bit ADC, RTC, and on-chip oscillators.
Does the R5F10EGAANA#20 support in-system programming via its serial interfaces?
Yes, the R5F10EGAANA#20 supports in-system programming using the on-chip debug interface (TOOL0/TOOLRxD/TOOLTxD) and also enables bootloader-based firmware updates via UART or CSI. Its self-programmable flash includes secure boot swap and flash shield window functions - allowing safe field updates while protecting critical boot code from corruption.
How many I²C interfaces does the R5F10EGAANA#20 support, and are they all independent?
The R5F10EGAANA#20 supports up to four I²C interfaces: two dedicated (SCLA0/SDAA0 and SCL00/SDA00), one shared with CSI11 (SCL11/SDA11), and one with CSI01 (SCL01/SDA01). All operate independently - the R5F10EGAANA#20 can act as multiple masters or slaves simultaneously, with separate address registers and interrupt vectors for each channel.
Can the R5F10EGAANA#20's ADC measure signals below 1.6 V?
No - the R5F10EGAANA#20's 12-bit ADC requires a minimum AVDD supply of 1.6 V and supports analog input ranges referenced to AVREFP/AVREFM. With the internal 1.45 V reference enabled, the effective measurable range is 0–1.45 V. Input signals below 0 V or exceeding AVDD are not supported and may damage the device if applied directly.
Is the exposed die pad on the R5F10EGAANA#20's HWQFN package electrically connected?
Yes, the exposed die pad on the R5F10EGAANA#20's 48-pin HWQFN package is internally connected to VSS. Renesas datasheet Rev.2.30 explicitly recommends connecting it to the system ground plane to improve thermal dissipation and reduce EMI - failure to do so may degrade analog performance and increase junction temperature under sustained operation.
