Product details
Overview
R5F11NGFAFB#10 from Renesas is a 48-pin LFQFP 16-bit RL78/H1D microcontroller with integrated analog front-end (24-bit ΔΣ A/D, PGA, 12-bit D/A), LCD controller/driver, and real-time clock 2. It delivers 33 DMIPS at 24 MHz, operates from 1.8 V to 5.5 V, and achieves 70.8 μA/MHz active power consumption - optimized for portable healthcare and flow metering systems requiring high-precision sensor signal conditioning and low-power display control.
For engineers reviewing the R5F11NGFAFB#10 datasheet, R5F11NGFAFB#10 pinout, R5F11NGFAFB#10 application, or R5F11NGFAFB#10 equivalent, this page provides verified technical context, validated pin functions, confirmed analog subsystem capabilities (including PGA gain x1–x64 and SNDR 85 dB), and direct alternative options for medical-grade sensor interface designs.
Technical Context
The R5F11NGFAFB#10 implements the RL78 CISC CPU core with 3-stage pipeline, supporting multiply/divide and MAC instructions. Its analog front-end includes a 24-bit second-order ΔΣ A/D converter (488 sps–15.625 ksps) and programmable gain instrumentation amplifier (PGA0) with differential/single-ended input support across 1–5 channels.
It integrates dual D/A converters (8-bit DAC0 and 12-bit DAC1), three rail-to-rail op-amps (AMP0–AMP2), and an LCD controller supporting up to 36 segments and 8 commons via internal boosting or external resistor division - all powered by dedicated LDOs (REGA, SBIAS) for sensor bias stability.

FAQ
What is the maximum sampling rate of the 24-bit ΔΣ A/D converter in R5F11NGFAFB#10?
The R5F11NGFAFB#10's 24-bit ΔΣ A/D converter supports up to 15.625 ksps in normal mode and 1.953 ksps in low-power mode. This specification is confirmed in the datasheet (R01DS0318EJ0111, Page 2), and applies directly to the R5F11NGFAFB#10 variant within the RL78/H1D family.
Does R5F11NGFAFB#10 support hardware-accelerated CRC calculation?
Yes, R5F11NGFAFB#10 includes a dedicated CRC calculation module supporting both 16-bit and 32-bit polynomials. This peripheral operates independently of the CPU and is documented in Section 1.5.3 of the datasheet (R01DS0318EJ0111, Page 15), enabling robust data integrity checks for flash updates or sensor communication without software overhead.
Can the SBIAS output of R5F11NGFAFB#10 be used to power external sensors?
Yes, the SBIAS pin on R5F11NGFAFB#10 provides a programmable 0.5–2.2 V reference output specifically designed to bias external bridge sensors or transducers. As stated in the datasheet (R01DS0318EJ0111, Page 2), it is regulated by an on-chip LDO and requires a 0.22 µF capacitor to AVSS for stability - making it suitable for precision sensor excitation in R5F11NGFAFB#10-based designs.
What LCD drive methods are supported by R5F11NGFAFB#10?
R5F11NGFAFB#10 supports three LCD bias generation methods: internal voltage boosting, capacitor-split, and external resistance division. These options are selectable via register configuration and allow flexible drive for 3- or 4-layer LCDs without external components - a capability explicitly confirmed for the R5F11NG series in Section 1.1 (Page 2) of the R5F11NGFAFB#10 datasheet.
Is the 12-bit D/A converter (DAC1) in R5F11NGFAFB#10 monotonic across its full range?
Yes, the 12-bit R-2R ladder D/A converter (DAC1) in R5F11NGFAFB#10 guarantees monotonicity across its entire 0–VREF range. This is inherent to its resistor-ladder architecture and verified in the electrical characteristics table of the datasheet (R01DS0318EJ0111, Page 112), ensuring predictable analog output behavior for calibration and sensor excitation in R5F11NGFAFB#10 applications.
