Product details
Overview
R5F101FLAFP#30 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates a 10-bit ADC (26 channels), RTC, UART/SPI/I²C interfaces, and ultra-low-power HALT/STOP/SNOOZE modes - ideal for battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101FLAFP#30 datasheet, R5F101FLAFP#30 pinout, R5F101FLAFP#30 application, or R5F101FLAFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, absence of on-chip data flash, industrial-grade temperature support, and compatibility with Renesas' RL78 toolchain and E2 studio IDE for rapid firmware development.
Technical Context
The R5F101FLAFP#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 dedicated SFRs enabling efficient peripheral control via bit-manipulation instructions.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, DMA controller (4 channels), and real-time clock with calendar function (99-year range), alarm, and clock correction - all configurable without external components. The high-accuracy ±1.0% on-chip oscillator eliminates need for external crystal in cost-sensitive applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101FLAFP#50 | Identical silicon; differs only in packaging - embossed tape instead of tray. | No functional difference; suited for automated SMT lines requiring tape-and-reel feed. | Select #50 for high-volume production with pick-and-place machines; #30 preferred for prototyping and small-batch assembly. |
| R5F100FLAFP#30 | Same package and pinout but includes 8 KB data flash memory. | Required where non-volatile parameter storage (e.g., calibration data, device ID) must survive power cycles without external EEPROM. | Choose R5F100FLAFP#30 if data logging or field-updatable configuration is needed; R5F101FLAFP#30 reduces BOM cost when data flash is unnecessary. |
Compared with R5F101FLAFP#30, the #50 variant offers identical electrical and functional behavior with optimized logistics handling, while R5F100FLAFP#30 adds data flash at marginally higher unit cost - making the R5F101FLAFP#30 optimal for cost-sensitive, flash-only firmware deployments.

FAQ
What is the maximum operating frequency of the R5F101FLAFP#30?
The R5F101FLAFP#30 operates at up to 32 MHz using its high-accuracy on-chip oscillator, delivering 41 DMIPS performance. This frequency is fully supported across the entire industrial temperature range (-40°C to +85°C) and 1.6 V to 5.5 V supply voltage, with no derating required under datasheet-specified conditions.
Does the R5F101FLAFP#30 include on-chip data flash memory?
No, the R5F101FLAFP#30 does not include on-chip data flash memory. As indicated by the '1' in the part number suffix (per Renesas RL78/G13 naming convention), this variant provides 96 KB of code flash and 8 KB of RAM only. For applications requiring non-volatile parameter storage, R5F100FLAFP#30 - which includes 8 KB data flash - is the functional counterpart.
What package type and pin count does the R5F101FLAFP#30 use?
The R5F101FLAFP#30 uses a 44-pin LQFP package with 10 mm × 10 mm body size and 0.8 mm lead pitch. The '#30' suffix denotes tray packaging, making it suitable for manual prototyping and low-volume assembly. Pin compatibility is maintained across all RL78/G13 44-pin LQFP variants, including R5F100xxAFP and R5F101xxAFP families.
Can the R5F101FLAFP#30 operate from a single 3.3 V supply?
Yes, the R5F101FLAFP#30 supports operation from a single 3.3 V supply within its specified 1.6 V to 5.5 V range. At 3.3 V, it maintains full functionality including 32 MHz operation, 10-bit ADC accuracy, and all peripheral interfaces - enabling direct integration with standard 3.3 V logic and sensor ecosystems without level translation.
What debug interface does the R5F101FLAFP#30 support?
The R5F101FLAFP#30 integrates a full-featured on-chip debug interface compatible with Renesas E2 emulator and E2 studio IDE. It supports breakpoints, watchpoints, real-time variable monitoring, flash programming, and SWD-style serial wire debug over dedicated TOOLRxD/TOOLTxD pins - eliminating need for external debug probes in development and production testing.
