Product details
Overview
R5F10E8CALA#U0 from Renesas Electronics is a 16-bit RL78/G1A microcontroller featuring 16 KB flash, 4 KB data flash, 2 KB RAM, 12-bit ADC with 24 channels, and ultra-low-power operation down to 0.57 µA in RTC+LVD mode. It operates from 1.6 V to 3.6 V, delivers 41 DMIPS at 32 MHz, and integrates UART, I²C, SPI, RTC, and programmable buzzer outputs - ideal for battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F10E8CALA#U0 datasheet, R5F10E8CALA#U0 pinout, R5F10E8CALA#U0 application, or R5F10E8CALA#U0 equivalent, key selection criteria include its WFLGA-25 package, 24-channel analog input capability, 0.57 µA RTC+LVD current draw, and support for 32 MHz on-chip oscillator with ±1% accuracy across voltage and temperature.
Technical Context
The R5F10E8CALA#U0 implements the RL78 16-bit CISC core with 3-stage Harvard pipeline, enabling 86% of instructions in 1–2 clock cycles and 16×16→32-bit multiply in one cycle. Its peripheral set includes two serial array units (supporting UART/I²C/CSI), an 8-channel timer array with PWM capability, and hardware CRC for flash integrity.
It features dual power domains (VDD/EVDD0) and separate analog/IO grounds (AVSS/EVSS0), supporting noise-sensitive mixed-signal applications. The device supports background data flash operation and secure boot swap, with LVD offering 12 configurable threshold levels for system-level supply monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10EBCANA#U0 | Same RL78/G1A family, 32-pin HWQFN package, 32 KB flash, 3 KB RAM, 18-channel ADC | Higher pin count and memory support more complex peripherals and larger firmware; lacks WFLGA footprint | Select when needing >24 ADC channels or additional UART/I²C instances beyond R5F10E8CALA#U0's 24-channel limit |
| R5F10EGCAFB#V0 | 48-pin LFQFP, 32 KB flash, 3 KB RAM, 24-channel ADC, same 0.57 µA RTC+LVD spec | Larger package enables full 48-pin pinout including EVDD0/EVSS0 separation and extra timers; supports 64-pin migration path | Choose for designs requiring enhanced noise isolation via separate analog/digital power domains and future scalability |
Compared with R5F10E8CALA#U0, the R5F10EBCANA#U0 offers higher memory and pin count in HWQFN but sacrifices the ultra-compact WFLGA form factor, while R5F10EGCAFB#V0 provides identical analog capability with superior power domain partitioning - making it preferable for EMI-critical medical or industrial applications.

FAQ
What is the operating voltage range of the R5F10E8CALA#U0?
The R5F10E8CALA#U0 operates from 1.6 V to 3.6 V over its full temperature range (−40°C to +85°C). This wide supply range enables direct interfacing with primary lithium batteries and compatibility with legacy 3.3 V and emerging 1.8 V subsystems without level translation. The on-chip voltage regulator maintains stable internal operation across this range, and the ADC supports analog inputs down to 1.6 V supply.
Does the R5F10E8CALA#U0 support hardware debugging?
Yes, the R5F10E8CALA#U0 includes a 1-wire on-chip debug function accessible via the P40/TOOL0 pin. This eliminates the need for dedicated SWD or JTAG headers, reducing PCB footprint and BOM cost. Debug capabilities include full breakpoint control, real-time variable watch, and flash programming - all supported by Renesas' CS+ and e2 studio IDEs without external debug probes.
How many analog input channels does the R5F10E8CALA#U0 provide?
The R5F10E8CALA#U0 provides 24 configurable analog input channels (ANI0–ANI24) mapped across ports P20–P27, P10–P15, P120, P02, P03, P30, P31, P50, P51, and P70. All channels support 12-bit resolution with 3.375 µs conversion time and operate down to 1.6 V supply, with internal 1.45 V reference and on-chip temperature sensor included.
What low-power modes are available on the R5F10E8CALA#U0?
The R5F10E8CALA#U0 offers multiple low-power states: Halt (0.57 µA with RTC + LVD active), Stop (0.23 µA with RAM retained), Snooze (0.6–0.7 mA for UART/ADC background operation), and Active (66 µA/MHz). These modes are controlled via system registers and support fast wake-up (< 4 µs from Stop), enabling precise energy budgeting in duty-cycled applications like wireless sensors.
Is the R5F10E8CALA#U0 pin-compatible with other RL78/G1A variants?
No, the R5F10E8CALA#U0 uses a 25-pin WFLGA package and is not pin-compatible with 32-pin HWQFN, 48-pin QFN/LFQFP, or 64-pin variants. Pin mapping differs significantly across packages due to port allocation and peripheral routing constraints. Migration requires PCB redesign, though software compatibility is maintained within the RL78/G1A family via common toolchain and peripheral register layout.
