Product details
Overview
R5F101LHABG#U0 from Renesas is a 64-pin VFBGA-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 12 KB RAM, and no data flash memory, operating from 1.6–5.5 V at -40°C to +105°C (industrial grade G). It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial motor control and sensor-based embedded systems.
For engineers reviewing the R5F101LHABG#U0 datasheet, R5F101LHABG#U0 pinout, R5F101LHABG#U0 application, or R5F101LHABG#U0 equivalent, key selection criteria include its VFBGA-64 (0.4 mm pitch) package, absence of on-chip data flash, industrial temperature rating, and compatibility with Renesas' RL78 toolchain and E2 studio for low-power firmware development.
Technical Context
The R5F101LHABG#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map includes 1 MB address space, 128 KB code flash organized in 1 KB blocks, and 12 KB on-chip RAM.
Power management includes HALT, STOP, and SNOOZE modes; reset functions integrate POR and 14-level LVD; peripherals include 16-bit timer (16 channels), 12-bit interval timer, RTC with calendar/alarm, watchdog timer, and 10-bit A/D converter with internal reference voltage (1.45 V) and temperature sensor - all validated for operation across -40°C to +105°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
VFBGA-64 package (PVBG0064LA-A), 4 mm × 4 mm, 0.4 mm pitch, top-side marking per Renesas standard. Pinout conforms to RL78/G13 64-pin mapping with dedicated power/ground pairs, dual VDD/VSS domains (core and I/O), and peripheral multiplexing on port pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS (x4) | Core power supply and ground | Dedicated pairs reduce noise coupling; decoupling required within 2 mm of each VDD pin |
| AVDD, AVSS | Analog power domain | Isolated analog supply improves ADC SNR; must be filtered separately from digital VDD |
| P00–P07, P10–P17, etc. | General-purpose I/O ports | Configurable as N-ch open-drain (6 V tolerant), TTL input, or pull-up; support 1.8/2.5/3.0 V interface levels |

| Self-programmable flash | Boot swap and flash shield window support secure field firmware updates without external programmer |
| Background data flash operation | Not applicable - R5F101LHABG#U0 has no data flash memory; code flash self-programming only |
| Hardware DMA controller | 4-channel DMA with 2-clock transfer between SFR and RAM - offloads CPU during ADC burst reads or UART streaming |
| Integrated RTC with calendar | 99-year calendar, alarm, and clock correction - eliminates need for external RTC IC in time-stamped logging applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LHABG#V0 | LQFP-64 package (0.65 mm pitch), same memory and peripherals | Easier prototyping and rework due to gull-wing leads; larger PCB footprint | Select #V0 for hand-soldered prototypes or low-volume production where VFBGA assembly is unavailable |
| R5F100LHABG#U0 | Includes 8 KB data flash; otherwise identical pinout, package, and core specs | Enables EEPROM-like parameter storage and firmware logging without external memory | Select #U0 variant if nonvolatile data retention is required; verify flash library RAM usage (FF300H start address) |
Compared with R5F101LHABG#U0, the #V0 alternative trades miniaturization for assembly simplicity, while the R5F100LHABG#U0 adds data flash at the cost of slightly higher active current - both retain identical timing, I/O, and industrial temperature qualification.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101LHABG#U0?
The R5F101LHABG#U0 operates at up to 32 MHz and delivers 41 DMIPS. This performance level is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The metric reflects integer instruction throughput under benchmark conditions and supports deterministic real-time tasks such as motor control loops and sensor fusion in the R5F101LHABG#U0.
Does the R5F101LHABG#U0 include on-chip data flash memory?
No, the R5F101LHABG#U0 does not include data flash memory. As indicated by the "101" prefix in the part number (per Renesas documentation), this variant provides only code flash (128 KB) and RAM (12 KB). Applications requiring nonvolatile parameter storage must use external EEPROM or utilize code flash sectors with wear-leveling firmware - unlike the R5F100LHABG#U0 which includes 8 KB of dedicated data flash.
What package type and dimensions does the R5F101LHABG#U0 use?
The R5F101LHABG#U0 uses a VFBGA-64 package (PVBG0064LA-A) with 0.4 mm pitch, measuring 4 mm × 4 mm. This fine-pitch ball grid array enables compact PCB designs ideal for space-constrained industrial modules. The #U0 suffix confirms tray packaging for automated SMT assembly, and the BG designation explicitly identifies the VFBGA form factor per Renesas' part numbering system.
What is the operating temperature range certified for the R5F101LHABG#U0?
The R5F101LHABG#U0 is rated for industrial operation from -40°C to +105°C, denoted by the "G" suffix in the part number. This qualification covers full functionality of all peripherals - including the 10-bit ADC, RTC, and communication interfaces - across the entire range. It meets JEDEC JESD22-A104 reliability standards and is suitable for under-hood automotive auxiliary systems and factory-floor controllers.
Which development tools and debug interfaces are supported for the R5F101LHABG#U0?
The R5F101LHABG#U0 supports Renesas E2 emulator Lite and E2 studio IDE via on-chip debug interface (OCDS). It is compatible with the RL78/G13 Target Board and RAJ-01E2LITE debugger. Firmware programming uses SWD (Serial Wire Debug) over the TOOLx pins, and the device supports flash self-programming with boot swap and flash shield window features - all fully documented in the R01DS0131EJ0380 datasheet for the R5F101LHABG#U0.
