Product details
Overview
R5F11PLGABG#U0 from Renesas is a 64-pin TFBGA-packaged RL78/H1D microcontroller featuring a 24-bit ΔΣ A/D converter with programmable gain instrumentation amplifier (PGA0), dual D/A converters (8-bit DAC0 and 12-bit DAC1), integrated LCD controller/driver (up to 36 segments × 8 commons), and true low-power operation (0.68 μA in Halt mode with RTC2 + LVD). It targets precision analog-sensing applications including medical glucose meters and industrial flow sensors.
For engineers reviewing the R5F11PLGABG#U0 datasheet, R5F11PLGABG#U0 pinout, R5F11PLGABG#U0 application, or R5F11PLGABG#U0 equivalent, this device delivers confirmed 128 KB flash, 5.5 KB RAM, 24 MHz RL78 CPU core (33 DMIPS), 10-bit SAR A/D (3 channels), and full peripheral integration-including UART, I²C, SPI, timers, and event link controller-optimized for battery-powered healthcare and metering systems.
Technical Context
The R5F11PLGABG#U0 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.04167 µs (@24 MHz) to 30.5 µs (@32.768 kHz), and includes multiply/divide and MAC instructions. Its analog front-end integrates a 24-bit ΔΣ A/D converter (SNDR: 85 dB TYP., output data rate 488 sps–15.625 ksps) with PGA0 (gain x1–x64) and rail-to-rail operational amplifiers (AMP0, AMP1, AMP2).

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11NLGAFB#30 | Same RL78/H1D core, 64-pin LFQFP (10×10 mm), identical 128 KB flash/5.5 KB RAM/analog IP | Requires larger PCB footprint; better thermal dissipation but incompatible with ultra-compact TFBGA layouts | Select when board space allows larger package or rework-friendly QFP is preferred over TFBGA. |
| R5F11NGGAFB#30 | 48-pin LFQFP variant; same analog subsystem but reduced I/O count (29 pins vs. 48) and no AMP2 or DAC1 | Suitable only for simpler sensor nodes without dual DAC or triple op-amp requirements | Choose for cost-sensitive, lower-complexity designs where 12-bit DAC and third op-amp are unnecessary. |
Compared with R5F11NLGAFB#30, the R5F11PLGABG#U0 saves 60% board area via TFBGA packaging while maintaining full analog feature parity; versus R5F11NGGAFB#30, it adds critical 12-bit DAC and third op-amp needed for closed-loop sensor calibration and multi-channel signal conditioning.

FAQ
What is the maximum operating frequency and performance of the R5F11PLGABG#U0?
The R5F11PLGABG#U0 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 33 DMIPS of processing performance. Its RL78 CPU core supports minimum instruction execution time of 0.04167 µs at 24 MHz, and includes hardware multiply/divide and multiply-accumulate instructions for efficient signal processing tasks in the R5F11PLGABG#U0.
Does the R5F11PLGABG#U0 support both 24-bit and 10-bit analog-to-digital conversion?
Yes, the R5F11PLGABG#U0 integrates two independent A/D subsystems: a 24-bit second-order ΔΣ A/D converter (with SNDR 85 dB TYP.) optimized for high-resolution sensor signals, and a separate 10-bit SAR A/D converter (3 channels) for faster control-loop sampling. Both operate across the full 1.8 V–5.5 V supply range, and the R5F11PLGABG#U0 datasheet confirms their concurrent usability.
What LCD configurations does the R5F11PLGABG#U0 support, and how many segments/commmons can it drive?
The R5F11PLGABG#U0 supports static and multiplexed LCDs via its integrated controller/driver, offering three voltage-generation methods: internal charge-pump boosting, capacitor-split, or external resistor division. It drives up to 36 segment outputs and 8 common outputs (configurable as 4 or 8 commons), enabling displays such as 36×4 or 32×8 segments - fully validated for the R5F11PLGABG#U0 in its datasheet.
How does the R5F11PLGABG#U0 achieve ultra-low power consumption in battery-operated devices?
The R5F11PLGABG#U0 achieves 0.68 μA in Halt mode (with RTC2 and LVD active) and 0.95 μA in STOP mode through dedicated low-leakage circuit design, multiple clock domain gating, and optimized analog block power control. Its 1.8 V minimum operating voltage allows direct use of single-cell Li-ion batteries, and the R5F11PLGABG#U0's SNOOZE mode enables peripheral-triggered wake-up without CPU intervention - critical for long-life portable medical devices.
What are the key analog peripherals integrated into the R5F11PLGABG#U0 beyond the A/D and D/A converters?
Beyond its 24-bit ΔΣ A/D and dual D/A converters, the R5F11PLGABG#U0 integrates three rail-to-rail operational amplifiers (AMP0, AMP1, AMP2), two programmable gain instrumentation amplifiers (PGA0 and PGA1), an analog bias reference (SBIAS: 0.5–2.2 V), and dedicated analog regulators (REGA, AVDD/AVSS). These are all confirmed in the R5F11PLGABG#U0 datasheet and enable complete front-end signal conditioning for precision sensor interfaces without external components.
