Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11EAAASP#30 | Same 30-pin LSSOP package and 8 KB flash, but includes 16 KB option variant; identical peripheral set and pinout | Identical use cases; selected when future firmware expansion headroom is required | Choose R5F11EAAASP#30 if bootloader or field-upgrade capability demands larger flash margin |
| R5F11EB8AFP#30 | 32-pin LQFP package, same 8 KB flash and 1.5 KB RAM, adds 4 additional I/O pins and KR0–KR3 key return inputs | Suitable for designs needing more GPIO or mechanical keypad interface without changing core firmware logic | Select R5F11EB8AFP#30 when board layout allows LQFP and additional I/O or key scan functionality is needed |
Compared with R5F11EA8ASP#30, R5F11EAAASP#30 offers identical footprint and peripherals with optional 16 KB flash for scalability, while R5F11EB8AFP#30 trades LSSOP compactness for LQFP I/O expansion and key scan support - both require no firmware changes but differ in mechanical integration.

FAQ
What is the maximum operating frequency of the R5F11EA8ASP#30 using its high-speed on-chip oscillator?
The R5F11EA8ASP#30 supports a high-speed on-chip oscillator frequency up to 24 MHz, enabling a minimum instruction execution time of 0.04167 µs. This frequency is selectable via option byte and HOCODIV register settings and maintains ±2.0% accuracy across –40°C to +85°C, making it suitable for timing-critical control loops without external crystals.
Does the R5F11EA8ASP#30 support self-programming of its flash memory?
Yes, the R5F11EA8ASP#30 supports self-programming of its 8 KB code flash memory using the flash shield window function. This capability requires use of Renesas' Flash Self-Programming Library Type01 and reserves 630 bytes of RAM during programming operations, as documented in the RL78/G1G User's Manual.
How many analog input channels does the R5F11EA8ASP#30 provide, and what is their resolution?
The R5F11EA8ASP#30 provides 8 analog input channels (ANI0–ANI3, ANI16–ANI19) with 10-bit resolution. It includes internal 1.45 V reference voltage and temperature sensor, and supports external reference inputs via AVREFP/AVREFM pins - all operating across the full 2.7–5.5 V supply range.
What are the power-saving modes supported by the R5F11EA8ASP#30, and how do they differ?
The R5F11EA8ASP#30 supports HALT, STOP, and SNOOZE modes. HALT stops the CPU clock while preserving RAM and register contents; STOP halts all clocks including peripherals for lowest current (<0.25 µA); SNOOZE allows selected peripherals (e.g., UART, A/D) to operate while CPU remains halted, enabling periodic wake-up without full restart overhead.
Is the R5F11EA8ASP#30 pin-compatible with other RL78/G1G family members in the same package?
Yes, the R5F11EA8ASP#30 shares identical 30-pin LSSOP pinout and peripheral mapping with R5F11EAAASP#30, including all analog inputs (ANI0–ANI3), timer I/O (TI01/TO01, TI03/TO03), UART (RxD0/TxD0), and debug interfaces (TOOLRxD/TOOLTxD). Firmware and PCB layouts are interchangeable between these variants.
