Product details
Overview
R5F101GJAFB#10 from Renesas is a 48-pin LFQFP-0.5mm-pitch, 256 KB flash, no data flash, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU with 16 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), deployed in smart metering and industrial sensor nodes.
For engineers reviewing the R5F101GJAFB#10 datasheet, R5F101GJAFB#10 pinout, R5F101GJAFB#10 application, or R5F101GJAFB#10 equivalent, key selection criteria include its 48-pin LFQFP package, absence of on-chip data flash, G-grade temperature rating, integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, and support for UART/LIN, I²C, and CSI serial interfaces.
Technical Context
The R5F101GJAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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, 16-bit timers (12 channels), watchdog timer, and DMA controller with 4 channels.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, HALT/STOP/SNOOZE low-power modes, and a high-accuracy ±1.0% on-chip oscillator (32 MHz to 1 MHz). Its memory subsystem comprises 256 KB code flash (1 KB block size), 16 KB RAM, and no data flash - distinguishing it from R5F100x variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC CPU with 3-stage pipeline and 1 MB address space |
| Max Operating Frequency | 32 MHz - delivers 41 DMIPS performance for deterministic real-time control |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GJAFB#10 | Includes 8 KB data flash and same 256 KB code flash; otherwise identical pinout, peripherals, and G-grade temp range | Enables EEPROM-like parameter storage and background firmware updates without external memory | Select when nonvolatile parameter retention or field firmware patching is required |
| R5F101GHAFB#10 | Same package and G-grade rating, but 192 KB code flash and 16 KB RAM - reduced memory capacity | Suitable for simpler control tasks with smaller firmware footprint and lower RAM demand | Select when application code size stays below 192 KB and cost optimization is prioritized |
Compared with R5F100GJAFB#10 and R5F101GHAFB#10, the R5F101GJAFB#10 offers optimal balance of memory headroom (256 KB flash) and cost efficiency for mid-tier industrial controllers, while omitting data flash avoids complexity where external EEPROM or FRAM suffices.

FAQ
What is the flash memory configuration of the R5F101GJAFB#10?
The R5F101GJAFB#10 contains 256 KB of code flash memory organized in 1 KB erasable blocks, with no on-chip data flash. This configuration supports robust firmware storage and secure self-programming via boot swap and flash shield window functions, but requires external nonvolatile memory for parameter logging or field updates that depend on background operation.
Does the R5F101GJAFB#10 support real-time clock functionality with calendar and alarm features?
Yes, the R5F101GJAFB#10 integrates a dedicated real-time clock (RTC) peripheral with full calendar support (99-year range), programmable alarm interrupt, and hardware clock correction. It operates independently in STOP mode using a 32.768 kHz crystal, enabling precise time-stamping and scheduled wake-up events essential for metering and telemetry applications.
What are the low-power operating modes supported by the R5F101GJAFB#10?
The R5F101GJAFB#10 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, typical current consumption is 0.57 μA - ideal for battery-backed applications. HALT mode reduces current to 66 μA/MHz during active operation, and SNOOZE mode allows selected peripherals (e.g., UART, ADC) to run while CPU sleeps, optimizing responsiveness versus power trade-offs.
Which serial communication interfaces are available on the R5F101GJAFB#10?
The R5F101GJAFB#10 provides up to 3 I²C/Simplified I²C channels, 2–4 UART/LIN channels (with LIN bus support), and 2–8 CSI (Simplified SPI) channels. All interfaces are multiplexed on GPIO pins and configurable via register settings, enabling concurrent use in multi-sensor systems - for example, I²C for environmental sensors, UART for modem communication, and CSI for display or memory expansion.
Is the R5F101GJAFB#10 pin-compatible with other RL78/G13 devices in the 48-pin LFQFP package?
Yes, the R5F101GJAFB#10 shares identical pinout and package (48-pin LFQFP, 0.5 mm pitch) with all other RL78/G13 variants in the same form factor, including R5F100GJAFB#10 and R5F101GHAFB#10. This enables drop-in replacement within the same footprint, provided firmware accounts for differences in memory size, data flash presence, and peripheral enablement.
