Product details
Overview
R5F11EFAAFP#10 from Renesas Electronics is a 44-pin LQFP ultra-low-power 16-bit RL78/G1G microcontroller with 16 KB flash, 1.5 KB RAM, 12-channel 10-bit ADC, dual comparators, and integrated PGA-designed for battery-powered sensor nodes and industrial control interfaces operating from -40°C to +85°C.
For engineers reviewing the R5F11EFAAFP#10 datasheet, R5F11EFAAFP#10 pinout, R5F11EFAAFP#10 application, or R5F11EFAAFP#10 equivalent, this page delivers verified specifications, validated 44-pin LQFP package mapping, confirmed peripheral I/O allocation (including TRDIOA0–TRDIOD1 timer I/O, ANI0–ANI7 analog inputs, and P70–P73 key return), and two production-ready alternative parts with documented functional and packaging differences.
Technical Context
The R5F11EFAAFP#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.04167 µs (24 MHz on-chip oscillator) to 1.0 µs (1 MHz), and includes multiply/divide/accumulate instructions. Its memory map spans 1 MB address space with 16 KB code flash organized in 1 KB blocks.
It integrates a high-speed on-chip oscillator (selectable 1–24 MHz, ±2% accuracy), low-speed 15 kHz on-chip oscillator, event link controller (19 input events, 6 trigger outputs), and power management features including HALT, STOP, and SNOOZE modes-all compliant with VDD = 2.7–5.5 V operation.

Pinout & Package
44-pin plastic LQFP (10 × 10 mm, 0.80 mm pitch) with REGC capacitor pad (0.47–1 µF to VSS), exposed thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Smart Home Sensor Hub | Industrial Motor Control Interface |
|---|---|
Use Scenario: Compact battery-powered hub aggregating temperature, humidity, and motion data from multiple analog and digital sensors. IC Role / Device Role / Timing Role: Central MCU managing 12-channel ADC sampling, UART-based sensor polling, and low-power SNOOZE-mode scheduling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11EF8AFP#10 | Same 44-pin LQFP package and RL78/G1G architecture, but 8 KB flash and 12-channel ADC retained | Suitable for cost-sensitive designs where firmware size < 8 KB and full 16 KB is unnecessary | Select when BOM cost reduction is prioritized and application code footprint fits within 8 KB |
| R5F11EBAAFP#10 | 32-pin LQFP variant with identical 16 KB flash, 1.5 KB RAM, and core peripherals-but only 28 I/O and 8-channel ADC | Applicable where board space is constrained and analog channel count ≤ 8 suffices | Choose for compact PCB layouts where reduced pin count and smaller footprint (7 × 7 mm) outweigh I/O and ADC limitations |
Compared with R5F11EF8AFP#10, the R5F11EFAAFP#10 provides double flash capacity for complex firmware or field-upgradable features; versus R5F11EBAAFP#10, it delivers 12 additional I/O pins and 4 extra ADC channels-critical for multi-sensor fusion or expanded control logic.

FAQ
What is the maximum operating frequency of the R5F11EFAAFP#10 using its internal oscillator?
The R5F11EFAAFP#10 supports a high-speed on-chip oscillator up to 24 MHz (±2% accuracy) in HS mode, enabling a minimum instruction execution time of 0.04167 µs. This frequency is selectable via option byte and HOCODIV register settings and does not require external crystals for basic operation.
Does the R5F11EFAAFP#10 support hardware debugging without external tools?
Yes, the R5F11EFAAFP#10 includes an integrated on-chip debug function accessible through TOOL0, TOOLRxD, and TOOLTxD pins. This allows full breakpoint, step-through, and memory inspection capability during development without requiring external JTAG or SWD adapters.
How many analog input channels does the R5F11EFAAFP#10 provide, and what reference options are available?
The R5F11EFAAFP#10 provides 12 analog input channels (ANI0–ANI7 and ANI16–ANI19) with 10-bit resolution. It supports external differential references via AVREFP and AVREFM pins, and includes an internal 1.45 V reference voltage source usable across the full 2.7–5.5 V VDD range.
Can the R5F11EFAAFP#10 drive standard 5 V logic levels directly from its GPIO pins?
No-the R5F11EFAAFP#10 GPIOs operate at VDD level (2.7–5.5 V) and are not 5 V tolerant in input mode unless configured with TTL input buffers (available on select pins like P01, P10, P15–P17, P30, P31, P50). Output high voltage is VDD − 0.5 V typical at 1 mA load; direct 5 V logic interfacing requires level-shifting for reliable operation.
What power-saving modes are implemented in the R5F11EFAAFP#10, and what are their typical current draws?
The R5F11EFAAFP#10 implements HALT (0.52 µA), STOP (0.37 µA), and SNOOZE modes. STOP mode disables the CPU and most peripherals while retaining RAM and certain wake-up sources; SNOOZE allows selected peripherals (e.g., ADC, UART) to operate autonomously during low-power sleep-ideal for periodic sensing tasks.
