Product details
Overview
R5F100LHAFB#V0 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers (12 channels), 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in smart metering, industrial sensor nodes, and battery-powered HMI controllers.
For engineers reviewing the R5F100LHAFB#V0 datasheet, R5F100LHAFB#V0 pinout, R5F100LHAFB#V0 application, or R5F100LHAFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature grade (G-suffix), integrated data flash with 1M-cycle endurance, and RL78 CPU core delivering 41 DMIPS at 32 MHz.
Technical Context
The R5F100LHAFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports multiple low-power modes - HALT, STOP, and SNOOZE - enabling sub-μA retention with RTC and LVD active.
On-chip peripherals include dual DMA channels (2 clocks for 8/16-bit SFR ↔ RAM transfers), hardware multiplier/divider/MAC, background data flash rewriting (BGO), and 12-bit interval timer plus calendar-mode RTC with alarm and clock correction - all operating across the full 1.6–5.5 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LJAFB#V0 | Same 64-pin LFQFP package, identical 128 KB flash/8 KB data flash/12 KB RAM, but rated for -40°C to +85°C (D grade) | Targeted at commercial/industrial ambient environments without extended temperature requirements | Select when full -40°C to +105°C operation is not required - lower cost and broader distributor availability |
| R5F101LHAFB#V0 | Pin-compatible 64-pin LFQFP variant with no data flash (0 KB), same 128 KB code flash and 12 KB RAM | Suitable where EEPROM-like nonvolatile parameter storage is handled externally or unnecessary | Choose when data logging or field-updatable configuration is not needed - reduces BOM cost and simplifies qualification |
Compared with R5F100LHAFB#V0, R5F100LJAFB#V0 trades extended temperature range for cost efficiency, while R5F101LHAFB#V0 removes data flash to reduce complexity and price - both retain identical core performance, peripheral count, and footprint for drop-in layout reuse.

FAQ
What is the operating temperature range for R5F100LHAFB#V0?
R5F100LHAFB#V0 is rated for industrial operation from -40°C to +105°C, confirmed by its 'G' suffix in the part number and specification in the RL78/G13 datasheet Rev.3.80. This makes it suitable for deployment in harsh environments such as factory floors, outdoor utility meters, and under-hood automotive subsystems where extended thermal stability is required.
Does R5F100LHAFB#V0 include an integrated data flash memory?
Yes, R5F100LHAFB#V0 includes 8 KB of dedicated data flash memory with 1,000,000 write/erase cycles (typical), supporting background operation (BGO) so code execution continues uninterrupted during rewrites. This enables reliable parameter storage, event logging, and firmware update staging without external EEPROM.
What package type and pin count does R5F100LHAFB#V0 use?
R5F100LHAFB#V0 uses a 64-pin LFQFP package with 0.5-mm pitch and 10 × 10 mm body size, as indicated by the 'FB' suffix and verified in Table 1-1 of the RL78/G13 datasheet. The #V0 packaging code specifies tray delivery - compatible with standard SMT pick-and-place equipment.
Can R5F100LHAFB#V0 operate from a single 1.8 V supply?
Yes, R5F100LHAFB#V0 supports 1.6 V to 5.5 V single-supply operation, including stable functionality at 1.8 V. Its I/O structure supports different-potential interfacing, allowing direct connection to 1.8 V logic devices without level shifters - validated across all operating modes including HALT and STOP.
How many ADC input channels does R5F100LHAFB#V0 support?
R5F100LHAFB#V0 supports up to 26 analog input channels for its 10-bit successive-approximation ADC, with selectable reference sources (internal 1.45 V or external AVREFP/AVREFM). This is confirmed in the "A/D converter" feature list and applies specifically to 64-pin variants like R5F100LHAFB#V0 per the RL78/G13 datasheet section 1.1.
