Product details
Overview
R5F101LGAFB#V0 from Renesas is a 64-pin LFQFP (0.5-mm pitch), 96 KB flash, 8 KB RAM, no data flash RL78/G13 16-bit microcontroller operating from 1.6–5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), used in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101LGAFB#V0 datasheet, R5F101LGAFB#V0 pinout, R5F101LGAFB#V0 application, or R5F101LGAFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated 10-bit ADC with 26-channel analog input support.
Technical Context
The R5F101LGAFB#V0 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, real-time clock with calendar/alarm functions, and watchdog timer with dedicated low-speed oscillator.
Peripheral integration includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 channel DMA controller, and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C (3–10 channels), all configurable for mixed-voltage I/O (1.8/2.5/3.0 V interface capability).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFB#V0 | Includes 4 KB data flash memory; identical code flash (96 KB), RAM (8 KB), and package (64-pin LFQFP). | Preferred where firmware requires nonvolatile parameter storage (e.g., calibration data, device ID) without external EEPROM. | Select R5F100LGAFB#V0 when data flash persistence is required; otherwise R5F101LGAFB#V0 reduces cost and simplifies flash management. |
| R5F101LHAFB#V0 | Same package and temperature grade, but with 128 KB code flash, 12 KB RAM, and no data flash-higher memory headroom. | Better suited for applications needing larger firmware (e.g., BLE stack + sensor fusion) or deeper RTOS task stacks. | Choose R5F101LHAFB#V0 if future firmware expansion or additional middleware is anticipated; pin-compatible with same PCB layout. |
Compared with R5F100LGAFB#V0, the R5F101LGAFB#V0 removes data flash to reduce cost and die size while retaining identical code flash, RAM, and peripheral set-ideal for fixed-function firmware. Versus R5F101LHAFB#V0, it trades memory capacity for lower unit cost and power in resource-constrained deployments.

FAQ
Does R5F101LGAFB#V0 include on-chip data flash memory?
No, R5F101LGAFB#V0 does not include on-chip data flash memory. This variant is specifically designated by the "101" prefix in the part number, indicating data flash omission. Code flash remains at 96 KB, and RAM is 8 KB. Applications requiring nonvolatile parameter storage must use external EEPROM or select the R5F100LGAFB#V0 variant, which includes 4 KB data flash.
What is the operating temperature range for R5F101LGAFB#V0?
R5F101LGAFB#V0 is rated for industrial operation from –40°C to +85°C, indicated by the "D" suffix in its full family designation (RL78/G13-D). It is not qualified for the extended –40°C to +105°C range (G-grade) or consumer-grade –40°C to +85°C with A-marking. This makes it suitable for factory automation, building controls, and outdoor metering equipment.
Which package type and footprint does R5F101LGAFB#V0 use?
R5F101LGAFB#V0 uses a 64-pin LFQFP package with 10 × 10 mm body size and 0.5-mm lead pitch (Renesas code PLQP0064KF-A). It features an exposed thermal pad and is compatible with standard QFP reflow profiles. The #V0 suffix confirms tray packaging-no tape-and-reel option is assigned to this specific variant.
How many analog input channels does R5F101LGAFB#V0 support?
R5F101LGAFB#V0 supports up to 26 analog input channels (ANI0–ANI25) via its 10-bit A/D converter. Pins P20, P21, P22, and P147 are dedicated analog inputs, while additional channels are multiplexed onto general-purpose I/O ports. Internal 1.45 V reference and temperature sensor are available, but only in HS (high-speed main) mode per datasheet Note 2.
Is R5F101LGAFB#V0 pin-compatible with other RL78/G13 64-pin variants?
Yes, R5F101LGAFB#V0 shares identical pinout and electrical characteristics with all other RL78/G13 64-pin LFQFP variants-including R5F100LGAFB#V0 and R5F101LHAFB#V0-ensuring full PCB layout compatibility. Differences are limited to memory configuration (code flash, RAM, data flash) and temperature grade, not pin function or drive strength.
