Product details
Overview
R5F11EAAASP#10 from Renesas is a 30-pin, 16 KB flash, 1.5 KB RAM RL78/G1G 16-bit microcontroller with ultra-low power consumption (HALT/STOP/SNOOZE modes), 8-channel 10-bit ADC, dual comparators, programmable gain amplifier, and integrated UART0/UART1, simplified SPI (CSI), and simplified I²C interfaces - deployed in battery-powered consumer appliances and industrial sensor nodes.
For engineers reviewing the R5F11EAAASP#10 datasheet, R5F11EAAASP#10 pinout, R5F11EAAASP#10 application, or R5F11EAAASP#10 equivalent, key selection criteria include its 30-pin LSSOP package, 2.7–5.5 V single-supply operation, -40°C to +85°C industrial temperature range, on-chip debug support, and flash self-programming capability for field firmware updates.
Technical Context
The R5F11EAAASP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 µs at 24 MHz high-speed on-chip oscillator). It integrates a voltage regulator with REGC capacitor support, POR/LVD reset circuitry, and event link controller (ELC) enabling 18 event inputs to trigger peripheral functions without CPU intervention.
Its analog subsystem includes AVREFP/AVREFM reference pins, internal 1.45 V reference, and temperature sensor (HS mode only); digital I/O supports N-ch open-drain, TTL input buffers, and on-chip pull-up resistors (10–100 kΩ), enabling direct interfacing with 2.5 V/3 V logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11EBAAFP#10 | 32-pin LQFP package, 28 I/O, same 16 KB flash/1.5 KB RAM, adds PORT7 (P70–P73) and extra analog channels | Requires PCB redesign due to larger footprint and different pinout; suited for designs needing >26 I/O or additional key return lines | Select when board layout allows LQFP and higher I/O count is required - no software changes needed |
| R5F11EA8ASP#10 | Same 30-pin LSSOP package and pinout, but 8 KB flash (vs. 16 KB), identical peripherals and timing specs | Drop-in replacement for cost-sensitive applications where firmware fits in 8 KB; retains full compatibility for pinout and driver code | Choose for lower-cost BOM when application firmware size ≤ 8 KB - zero hardware or software adaptation |
Compared with R5F11EBAAFP#10, the R5F11EAAASP#10 saves board space and reduces routing complexity in compact designs; versus R5F11EA8ASP#10, it doubles flash capacity for feature-rich firmware while maintaining identical footprint and I/O mapping.

FAQ
What is the maximum operating frequency of the R5F11EAAASP#10 using its internal oscillator?
The R5F11EAAASP#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 is fully functional across the rated 2.7–5.5 V supply and -40°C to +85°C temperature range.
Does the R5F11EAAASP#10 support hardware debugging during development?
Yes, the R5F11EAAASP#10 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug access uses the TOOL0, TOOLRxD, and TOOLTxD pins (P40, P50, P51), and supports breakpoints, watchpoints, and flash programming - though Renesas advises against using debug features in mass-produced units to preserve flash endurance.
How many analog input channels does the R5F11EAAASP#10 support, and what are their design constraints?
The R5F11EAAASP#10 supports 8 analog input channels: ANI0–ANI3 (P20–P23) and ANI16–ANI19 (P00, P01, P147, P120). These operate at 10-bit resolution with VDD = 2.7–5.5 V. The internal 1.45 V reference and AVREFP/AVREFM pins allow flexible single-ended or pseudo-differential configurations, but temperature sensor use is restricted to HS mode per the datasheet.
Can the R5F11EAAASP#10 drive standard 5 V logic directly from its GPIO pins?
No - the R5F11EAAASP#10 GPIOs are not 5 V tolerant in output mode. Its absolute maximum output voltage is VDD + 0.3 V, and VOH/VOL specs assume VDD = 2.7–5.5 V. To interface with 5 V systems, level-shifting circuitry or N-ch open-drain outputs with external pull-ups to 5 V (not exceeding 6 V per absolute max rating) must be used.
What packaging and ordering options are available for the R5F11EAAASP#10?
The R5F11EAAASP#10 is supplied in 30-pin plastic LSSOP (0.65 mm pitch) packaged in trays (#10 and #30 suffixes). The "SP" in the part number explicitly denotes the LSSOP package type, and the "#10" suffix indicates tray packaging - consistent with Renesas' standard ordering nomenclature for this device family.
