Product details
Overview
R5F101LHAFB#V0 from Renesas is a 64-pin LFQFP, 0.5-mm pitch, 128 KB flash, 12 KB RAM, RL78/G13 16-bit microcontroller operating at up to 32 MHz with 41 DMIPS, ultra-low power (66 μA/MHz active, 0.57 μA RTC+LVD), and integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F101LHAFB#V0 datasheet, R5F101LHAFB#V0 pinout, R5F101LHAFB#V0 application, or R5F101LHAFB#V0 equivalent, key selection criteria include its data flash omission (vs. R5F100x variants), -40°C to +85°C industrial-grade temperature range (D-grade), LFQFP-64 package compatibility, and support for SNOOZE mode operation with background data flash rewriting.
Technical Context
The R5F101LHAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 3× I²C/Simplified I²C channels, 2× UART/LIN, 2× CSI (SPI-compatible), 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

Applications
| Smart Energy Metering | Industrial Sensor Node |
|---|---|
|
Use Scenario: Bidirectional energy measurement with tamper detection, time-of-use billing, and secure firmware updates. IC Role / Device Role / Timing Role: Main system controller managing metrology IC interface (SPI), RTC timestamping, AES encryption co-processing, and LCD driver output.

Use Scenario: Wireless vibration/temperature monitoring in predictive maintenance systems with local edge analytics. IC Role / Device Role / Timing Role: Signal acquisition hub aggregating multi-channel analog (vibration, temp) and digital (I²C sensors), performing FFT preprocessing before BLE transmission. Use Value: 26-channel 10-bit ADC captures high-fidelity sensor waveforms; SNOOZE mode enables continuous sampling while retaining RTC timekeeping. |
| Home Appliance Control | Building Automation Panel |
|
Use Scenario: Motor control and user interface for HVAC fan units with touch sensing and fault diagnostics. IC Role / Device Role / Timing Role: Real-time motor commutation (via timer PWM outputs), capacitive touch scanning (CTSU), and buzzer feedback generation. Use Value: Integrated 16-bit timers deliver precise 3-phase PWM with dead-time insertion; on-chip key interrupt reduces GPIO count for touch buttons. |

IC Role / Device Role / Timing Role: DALI physical layer interface (UART + isolated transceiver), ambient light/temp sensing, and schedule-based relay actuation. Use Value: Dual UARTs support DALI master/slave roles and debug port simultaneously; 1.6–5.5 V operation tolerates wide-range 24 V DC supply fluctuations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LHAFB#V0 | Includes 8 KB data flash; identical code flash (128 KB), RAM (12 KB), package, and peripherals | Required where field firmware updates or parameter storage demand non-volatile data retention | Select when data flash is needed for configuration storage or logging - adds ~$0.15 BOM cost |
| R5F101LHAFP#V0 | LQFP-64 (0.65-mm pitch) instead of LFQFP-64 (0.5-mm pitch); same memory/peripherals/temperature grade | Preferred for legacy PCB layouts using standard 0.65-mm pitch footprints; requires board rework for 0.5-mm pitch | Choose for drop-in replacement on existing LQFP-64 designs - no firmware changes required |
Compared with R5F100LHAFB#V0, the R5F101LHAFB#V0 omits data flash to reduce cost and die size while maintaining identical code execution capability and low-power performance; versus R5F101LHAFP#V0, it enables higher-density PCB layouts via finer 0.5-mm pitch but requires updated stencil and placement tooling.

FAQ
Does R5F101LHAFB#V0 include data flash memory?
No, R5F101LHAFB#V0 does not include data flash memory. It provides 128 KB of code flash and 12 KB of RAM only. Data flash (4–8 KB) is present in the R5F100x series variants (e.g., R5F100LHAFB#V0), but omitted in the R5F101x family to reduce cost and die area while retaining full code execution capability. The R5F101LHAFB#V0 retains all other peripherals including ADC, RTC, and serial interfaces.
What is the operating temperature grade of R5F101LHAFB#V0?
R5F101LHAFB#V0 is rated for industrial operation from -40°C to +85°C (D-grade). This is confirmed by the 'D' suffix in the part number decoding per Renesas documentation (Figure 1-1), and aligns with JEDEC JESD22-A108 reliability testing. It is not rated for extended -40°C to +105°C (G-grade) operation.
Which package type does R5F101LHAFB#V0 use?
R5F101LHAFB#V0 uses a 64-pin LFQFP package with 0.5-mm pitch and 10 × 10 mm body size (RENESAS Code PLQP0064KF-A). The '#V0' suffix explicitly denotes tray packaging for LFQFP/LQFP/TSSOP/LSSOP packages per Table 1-1. This differs from LQFP-64 (0.65-mm pitch) variants such as R5F101LHAFP#V0.
Can R5F101LHAFB#V0 operate from a 1.8 V supply?
Yes, R5F101LHAFB#V0 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supplies. At 1.8 V, maximum operating frequency is reduced to 16 MHz (per electrical characteristics table in R01DS0131EJ0380), and certain peripherals like the high-speed oscillator require configuration adjustment. The 10-bit ADC remains fully functional with internal 1.45 V reference.
Does R5F101LHAFB#V0 support background data flash rewriting?
No - R5F101LHAFB#V0 lacks data flash memory entirely, so background data flash rewriting (BGO) is not applicable. However, it fully supports background operation for *code flash* self-programming (e.g., bootloader updates) using the flash shield window function and boot swap mechanism, as documented in Section 1.1 Features of R01DS0131EJ0380.
