Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11PLGABG#U0 | Same RL78/H1D core, identical analog peripherals and memory (96 KB flash/5.5 KB RAM), but in 64-pin TFBGA (4 × 4 mm, 0.4 mm pitch) | Targeted for ultra-compact PCB layouts where footprint area is constrained; no change in thermal or electrical performance | Select when board space is critical and rework capability supports BGA assembly. |
| R5F11NGGAFB#30 | Same analog features and core, but 48-pin LFQFP package with reduced I/O count (29 pins vs. 63) and 128 KB flash/5.5 KB RAM | Used in cost-sensitive, lower-I/O designs such as basic flow indicators without advanced diagnostics or multi-sensor support | Select when fewer GPIOs and smaller package suffice, and higher flash capacity is beneficial for firmware updates. |
Compared with R5F11NLGAFB#30, R5F11PLGABG#U0 offers identical functionality in a smaller footprint but requires BGA handling, while R5F11NGGAFB#30 trades I/O count and package size for increased flash-making it suitable for simpler, space-constrained implementations where full 64-pin I/O is unnecessary.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F11NLGAFB#30?
The R5F11NLGAFB#30 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 33 DMIPS performance. This is confirmed in the datasheet's "Outline" section and aligns with the RL78 core's 3-stage pipeline execution efficiency. The R5F11NLGAFB#30 maintains this performance across its full 1.8 V to 5.5 V supply range.
Does the R5F11NLGAFB#30 include both 24-bit ΔΣ and 10-bit SAR A/D converters, and how are they used together?
Yes, the R5F11NLGAFB#30 integrates both a 24-bit ΔΣ A/D converter (for high-precision, low-frequency sensor signals like load cells or thermopiles) and a separate 10-bit SAR A/D converter (for faster measurements such as temperature or supply monitoring). They share analog input channels (ANI8/ANI10/ANI11), with selection controlled by register configuration. The R5F11NLGAFB#30 datasheet specifies distinct SNDR (85 dB) and conversion rates for the ΔΣ unit, and 1.45 V internal reference for the SAR unit.
What LCD drive configurations does the R5F11NLGAFB#30 support, and what is the maximum segment count?
The R5F11NLGAFB#30 supports three LCD voltage generation methods: internal voltage boosting, capacitor split, and external resistance division. It provides up to 36 segment outputs (SEG0–SEG35) and 8 common outputs (COM0–COM7), enabling direct drive of alphanumeric or custom segment displays without external bias circuitry. These capabilities are explicitly documented in the "LCD controller/driver" feature list and block diagram for 64-pin LFQFP variants.
What are the key power-saving modes supported by the R5F11NLGAFB#30, and what is the lowest achievable current draw?
The R5F11NLGAFB#30 supports HALT, STOP, and SNOOZE modes. In HALT mode with RTC2 and LVD enabled, it achieves 0.68 μA typical current draw-verified in the "True Low Power Platform" section of the datasheet. This ultra-low quiescent current enables multi-year operation on coin-cell batteries in portable medical and metering applications. The R5F11NLGAFB#30 also achieves 70.8 μA/MHz in active mode, confirming its energy efficiency per compute cycle.
How many operational amplifiers and programmable gain amplifiers are integrated into the R5F11NLGAFB#30, and what are their roles?
The R5F11NLGAFB#30 integrates one rail-to-rail operational amplifier (AMP0) and three general-purpose op-amps (AMP1, AMP2), plus two programmable gain instrumentation amplifiers: PGA0 (gain x1–x64) and PGA1 (gain x12/x16/x20/x24). PGA0 is optimized for front-end sensor signal conditioning, while AMP0 serves as a buffer or filter stage. These analog resources are exclusive to R5F11N/R5F11P variants and fully implemented in the R5F11NLGAFB#30.
