Product details
Overview
R5F10EGEANA#20 from Renesas Electronics is a 48-pin HWQFN-packaged 16-bit RL78/G1A microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 12-bit 28-channel ADC, and ultra-low-power operation down to 0.57 µA in RTC+LVD halt mode. It targets battery-powered industrial sensors and smart metering systems requiring high analog integration and deterministic real-time control.
For engineers reviewing the R5F10EGEANA#20 datasheet, R5F10EGEANA#20 pinout, R5F10EGEANA#20 application, or R5F10EGEANA#20 equivalent, key selection criteria include its 48-pin HWQFN (7×7 mm, 0.5 mm pitch) package, 32 MHz max CPU frequency delivering 41 DMIPS, integrated RTC with 1 Hz output (RTC1HZ), and support for up to 6 UART/I²C/SPI interfaces with peripheral I/O redirection.
Technical Context
The R5F10EGEANA#20 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its on-chip debug uses 1-wire TOOL0/TOOLRxD/TOOLTxD interface, and memory protection includes flash shield window, data flash background operation, and SFR write lock.
Power management integrates POR, 12-level LVD with interrupt/reset options, and multiple low-power modes: Stop (0.23 µA), Halt (0.57 µA), Snooze (0.6–0.7 mA), and active operation at 66 µA/MHz. The high-speed on-chip oscillator delivers ±1% accuracy from 1.8–3.6 V and −20°C to +85°C.

FAQ
What is the operating voltage range of the R5F10EGEANA#20?
The R5F10EGEANA#20 operates from 1.6 V to 3.6 V across its full industrial temperature range (−40°C to +105°C). This wide supply range enables direct compatibility with single-cell Li-ion, LiFePO₄, and alkaline battery sources without external regulation, and supports brown-out resilience during transient voltage dips.
Does the R5F10EGEANA#20 support hardware-based functional safety features?
Yes, the R5F10EGEANA#20 includes multiple hardware safety mechanisms compliant with IEC/UL 60730 Class B requirements: flash memory CRC calculation engine, RAM parity error detection, SFR write protection, illegal memory access detection, clock stop/frequency monitoring, and ADC self-test capability-all implemented in dedicated hardware blocks without software overhead.
How many serial communication interfaces does the R5F10EGEANA#20 provide?
The R5F10EGEANA#20 supports up to six serial interfaces: three UARTs (7-/8-/9-bit), six I²C masters (including one multi-master), and six Simplified SPI (CSI) channels. These are distributed across multiple serial array units and support peripheral I/O redirection, allowing flexible pin assignment for mixed-protocol system designs.
What is the significance of the "G" suffix in the R5F10EGEANA#20 part number?
The "G" in R5F10EGEANA#20 denotes industrial-grade qualification, specifying an extended operating ambient temperature range of −40°C to +105°C. This distinguishes it from consumer-grade "A" variants (−40°C to +85°C) and ensures reliability in harsh environments such as factory automation, outdoor metering, and motor control enclosures.
Can the R5F10EGEANA#20 operate without an external crystal oscillator?
Yes, the R5F10EGEANA#20 can operate entirely from its high-speed on-chip oscillator (32 MHz, ±1% accuracy), eliminating the need for external crystals in most applications. External oscillators (X1/X2 or XT1/XT2) are optional and used only when higher precision timing-such as for USB or synchronous serial protocols-is required.
