Overview
R5F11NGGAFB#30 from Renesas is a 48-pin LFQFP 16-bit RL78/H1D microcontroller with integrated analog front-end (24-bit ΔΣ A/D converter, programmable gain instrumentation amplifier PGA0/PGA1, rail-to-rail op-amps AMP0–AMP2, and dual D/A converters), LCD controller/driver (36 segments × 4 commons), and real-time clock 2. It operates from 1.8 V to 5.5 V, delivers 33 DMIPS at 24 MHz, and targets ultra-low-power healthcare and flow meter applications.
For engineers reviewing the R5F11NGGAFB#30 datasheet, R5F11NGGAFB#30 pinout, R5F11NGGAFB#30 application, or R5F11NGGAFB#30 equivalent, this page provides verified technical context, exact pin functions for PCB layout, confirmed analog performance specs (SNDR = 85 dB, PGA gain x1–x64), and validated alternatives for medical sensor signal conditioning and battery-powered metering designs.
Technical Context
The R5F11NGGAFB#30 implements the RL78 CISC CPU core with 3-stage pipeline, supporting multiply/divide and MAC instructions. Its analog subsystem includes two independent PGA stages (PGA0 with x1–x64 gain, PGA1 with x12/x16/x20/x24), three rail-to-rail op-amps, and dual D/A converters (8-bit DAC0 and 12-bit DAC1) - all powered by dedicated LDOs (REGA, SBIAS).
It integrates a 24-bit second-order ΔΣ A/D converter (488 sps–15.625 ksps output rate, SNDR 85 dB TYP.) and a 10-bit SAR A/D converter (3-channel, internal 1.45 V reference). The device supports event-driven peripheral control via ELC (18–26 event sources) and background data flash rewriting (1M cycles, BGO enabled).

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F11NGGAFB#30?
The R5F11NGGAFB#30 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 33 DMIPS of processing performance. This speed is achievable across the full 1.8 V to 5.5 V supply range and supports minimum instruction execution times as fast as 0.04167 µs. The R5F11NGGAFB#30 maintains consistent performance without requiring external crystals for core timing.
Does the R5F11NGGAFB#30 support both 24-bit delta-sigma and 10-bit SAR analog-to-digital conversion simultaneously?
Yes, the R5F11NGGAFB#30 integrates two independent ADC subsystems: a 24-bit ΔΣ converter (with PGA0/PGA1 and SNDR 85 dB) and a separate 10-bit SAR converter (3-channel, internal 1.45 V reference). Both can operate concurrently-enabling simultaneous high-resolution sensor measurement and fast auxiliary signal sampling without resource conflict. The R5F11NGGAFB#30 assigns ANI8–ANI10 to both converters via configurable input muxes.
What LCD configuration options does the R5F11NGGAFB#30 support, and how many segments/commoms are available?
The R5F11NGGAFB#30's integrated LCD controller supports static and multiplexed displays with up to 36 segment outputs (SEG0–SEG35) and 4 common outputs (COM0–COM3). It offers three bias methods-internal voltage boosting, capacitor-split, and external resistance division-allowing direct drive of LCDs from 2.4 V to 5.5 V. The R5F11NGGAFB#30 requires no external bias ICs or charge pumps for standard 3V/5V LCD modules.
How does the analog front-end power architecture of the R5F11NGGAFB#30 isolate sensitive measurement circuits?
The R5F11NGGAFB#30 employs three dedicated analog power domains: AVDD/AVSS for the ΔΣ ADC and PGAs, REGA for internal analog circuitry (requiring 0.22 µF decoupling to AVSS), and SBIAS for external sensor bias (0.5–2.2 V, decoupled with 0.22 µF). This separation prevents digital switching noise from degrading 24-bit measurement integrity. The R5F11NGGAFB#30 mandates physical separation of AVSS and VSS traces on PCBs per datasheet layout guidelines.
What are the key low-power modes supported by the R5F11NGGAFB#30, and what is the lowest achievable current draw?
The R5F11NGGAFB#30 supports HALT, STOP, and SNOOZE modes. In HALT mode with RTC2 and LVD active, it draws just 0.68 μA-enabling decade-scale battery life in metering applications. Active-mode current is 70.8 μA/MHz, and the device retains full SRAM content and register states across all low-power states. The R5F11NGGAFB#30 achieves this via dedicated low-leakage analog regulators and clock gating at the peripheral level.
