Product details
Overview
R5F101FLAFP#X0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (24 channels), and integrated real-time clock - deployed in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101FLAFP#X0 datasheet, R5F101FLAFP#X0 pinout, R5F101FLAFP#X0 application, or R5F101FLAFP#X0 equivalent, key selection criteria include its data flash absence (vs. R5F100x variants), 44-pin LQFP-0.8mm pitch package, -40°C to +85°C industrial temperature grade (D), and support for LIN-bus UART, CSI, and I²C peripherals in space-constrained embedded control designs.
Technical Context
The R5F101FLAFP#X0 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 subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8 CSI channels, 16× 16-bit timers, and an 8/10-bit ADC with internal 1.45 V reference and temperature sensor - all configurable via register-level control without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FLAFP#X0 | Same package and pinout, but includes 8 KB data flash (R5F101FLAFP#X0 has none) | Required where field-upgradable parameter storage (e.g., calibration tables) is needed | Select R5F100FLAFP#X0 if data flash persistence is mandatory; otherwise R5F101FLAFP#X0 reduces cost and simplifies flash management |
| RL78/G14 R5F117FLAFP#X0 | Successor family with 128 KB flash, enhanced ADC (12-bit), and additional DMA channels | Suitable for next-gen designs needing higher code density or precision analog acquisition | Choose R5F117FLAFP#X0 only when new design requires >96 KB flash or 12-bit ADC resolution; not drop-in compatible due to register map differences |
Compared with R5F100FLAFP#X0, the R5F101FLAFP#X0 trades data flash for lower unit cost and simplified firmware update logic, while the RL78/G14 alternative offers architectural enhancements at the expense of migration effort - making R5F101FLAFP#X0 optimal for cost-sensitive, flash-static industrial controls.

FAQ
Does R5F101FLAFP#X0 include data flash memory?
No, R5F101FLAFP#X0 does not include data flash memory. Unlike the R5F100x series (e.g., R5F100FLAFP#X0), the "101" prefix explicitly denotes zero data flash capacity. This simplifies flash programming workflows and reduces cost where non-volatile parameter storage is handled externally or omitted entirely. The R5F101FLAFP#X0 retains full code flash functionality (96 KB) and supports self-programming via boot swap.
What is the operating temperature grade of R5F101FLAFP#X0?
R5F101FLAFP#X0 is rated for industrial operation from -40°C to +85°C (D-grade). This is confirmed by its part number suffix "D" in the RL78/G13 naming convention and aligns with Renesas' specification for reliability in factory automation, metering, and outdoor equipment. It does not support the extended -40°C to +105°C (G-grade) range.
Which package type and pin count does R5F101FLAFP#X0 use?
R5F101FLAFP#X0 uses a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch), indicated by the "FP" in the part number and verified in Table 1-1 of the R01DS0131EJ0380 datasheet. The "#X0" suffix confirms embossed tape packaging - standard for automated SMT assembly. Pin compatibility is maintained across all RL78/G13 44-pin LQFP variants.
Can R5F101FLAFP#X0 operate from a 1.8 V supply?
Yes, R5F101FLAFP#X0 supports operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, maximum clock frequency is reduced per the datasheet's voltage-frequency curve (typically ≤ 16 MHz), but all peripherals - including ADC, RTC, and UART - remain fully functional. This enables direct interfacing with 1.8 V logic and low-voltage battery systems.
Does R5F101FLAFP#X0 support LIN bus communication?
Yes, R5F101FLAFP#X0 supports LIN bus communication via its UART peripheral, which includes LIN-break detection, sync-field generation, and checksum handling per LIN 2.2A specification. No external transceiver is required for basic LIN node implementation, though a physical-layer transceiver (e.g., TJA1020) is needed for bus termination and ESD protection in production systems.
How many ADC channels does R5F101FLAFP#X0 provide?
R5F101FLAFP#X0 provides 24 analog input channels for its 8/10-bit successive-approximation ADC. Channel mapping includes dedicated pins (e.g., ANI0–ANI23) and multiplexed port functions. The ADC supports internal 1.45 V reference and integrated temperature sensor - both accessible without external components - enabling compact analog front-end designs.
