Renesas R5F101FHAFP#30

Overview

R5F101FHAFP#30 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 12-bit ADC (26 channels), real-time clock, UART/LIN, I²C, SPI, 16-bit timers, and operates from 1.6–5.5 V for battery-powered industrial sensors and smart meters.

For engineers reviewing the R5F101FHAFP#30 datasheet, R5F101FHAFP#30 pinout, R5F101FHAFP#30 application, or R5F101FHAFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode for low-latency wake-up in energy-constrained edge nodes.

Technical Context

The R5F101FHAFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.

Power management includes HALT, STOP, and SNOOZE modes; on-chip POR and 14-level LVD; and background data flash rewriting (BGO). Peripheral integration covers up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, plus dual UART/LIN interfaces with automatic LIN header detection.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F101FHAFP#30?

The R5F101FHAFP#30 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This is measured under standard conditions (VDD = 2.7–5.5 V, TA = -40°C to +85°C) and reflects the RL78 CPU core's 3-stage pipeline efficiency. The R5F101FHAFP#30 maintains this performance across its full industrial temperature range without derating.

Does the R5F101FHAFP#30 include on-chip data flash memory?

No, the R5F101FHAFP#30 does not include on-chip data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, this variant provides 96 KB of code flash only. In contrast, R5F100x parts (e.g., R5F100FHAFP#30) include 4 KB of data flash. The R5F101FHAFP#30 relies on external non-volatile storage or RAM-backed parameter retention for configuration data.

What package type and pin pitch does the R5F101FHAFP#30 use?

The R5F101FHAFP#30 uses a 44-pin plastic LQFP package (10 × 10 mm body) with 0.8-mm pin pitch, identified by the "FP" suffix in Renesas' packaging code. This package is RoHS-compliant, surface-mountable, and compatible with standard PCB assembly processes including reflow soldering. The #30 suffix denotes tray packaging for automated pick-and-place handling.

Which communication interfaces are supported by the R5F101FHAFP#30?

The R5F101FHAFP#30 supports UART/LIN (2 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible serial interface, up to 8 channels). All interfaces are implemented in hardware with dedicated registers and interrupt capability. LIN functionality includes automatic header detection and checksum generation, enabling direct connection to automotive or industrial LIN bus networks without external protocol assist chips.

What is the ADC resolution, channel count, and reference voltage option for the R5F101FHAFP#30?

The R5F101FHAFP#30 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports both external reference inputs and an internal 1.45 V reference voltage (AVREFP/AVREFM), selectable via register configuration. The ADC operates across the full 1.6–5.5 V supply range and includes a built-in temperature sensor usable for ambient monitoring or system calibration.
