Product details
Overview
R5F101LJABG#U0 from Renesas is a 64-pin VFBGA-packaged RL78/G13 16-bit microcontroller with 192 KB flash, 8 KB data flash, 16 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F101LJABG#U0 datasheet, R5F101LJABG#U0 pinout, R5F101LJABG#U0 application, or R5F101LJABG#U0 equivalent, key selection criteria include its VFBGA-64 package, absence of on-chip data flash (R5F101x series), -40°C to +105°C temperature grade (G suffix), and support for low-power SNOOZE/STOP/HALT modes in resource-constrained embedded systems.
Technical Context
The R5F101LJABG#U0 implements the RL78 CPU core with a 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 features 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 2–4 DMA channels, 16-bit timer array (up to 16 channels), 12-bit interval timer, calendar-based RTC with alarm/correction, 8/10-bit ADC with internal 1.45 V reference and temperature sensor, and multi-channel serial interfaces (CSI, UART/LIN, I²C) - all optimized for deterministic real-time control in cost-sensitive industrial applications.
Key Specifications

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101LJABG#U0?
The R5F101LJABG#U0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction timing - from 0.03125 μs at full speed to 30.5 μs in ultra-low-power 32.768 kHz mode - enabling dynamic trade-offs between throughput and energy consumption in the R5F101LJABG#U0.
Does the R5F101LJABG#U0 include on-chip data flash memory?
No, the R5F101LJABG#U0 does not include dedicated data flash memory. As indicated by the "101" in its part number (per Renesas RL78/G13 documentation), it belongs to the data-flash-less variant series. Non-volatile parameter storage must be implemented using code flash with self-programming and flash shield window protection - a confirmed feature of the R5F101LJABG#U0.
What package type and footprint does the R5F101LJABG#U0 use?
The R5F101LJABG#U0 uses a VFBGA-64 package (4 mm × 4 mm, 0.4 mm pitch), identified by the "BG" suffix and "#U0" tray packaging code. Its JEDEC MO-220-compliant footprint (PVBG0064LA-A) supports high-density PCB layouts and automated assembly, with verified ball mapping matching the RL78/G13 64-pin VFBGA pinout specification for the R5F101LJABG#U0.
What is the operating temperature range for the R5F101LJABG#U0?
The R5F101LJABG#U0 is rated for industrial operation from -40°C to +105°C, denoted by the "G" suffix in its part number. This extended temperature grade ensures reliable functionality in demanding environments such as factory automation controls, outdoor utility infrastructure, and motor-drive interfaces - a confirmed specification for the R5F101LJABG#U0.
Which low-power modes are supported by the R5F101LJABG#U0, and what are their typical current draws?
The R5F101LJABG#U0 supports HALT (0.73 μA), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. These modes enable aggressive power gating while retaining critical functions - for example, STOP mode maintains real-time clock operation and low-voltage detection without waking the CPU, a documented capability of the R5F101LJABG#U0 used in multi-year battery applications.
