Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GJGFB#10 | No data flash (0 KB); same core, peripherals, and package. | Not suitable for field-upgradable firmware or data logging; limited to static configuration storage. | Select when firmware is immutable and no runtime parameter storage is required-reduces cost and flash wear. |
| RL78/G14 R5F104GJGFB#10 | Enhanced RL78/G14 core; adds USB 2.0 FS, larger RAM (16 KB), and higher max frequency (48 MHz). | Required for USB-connected devices (e.g., PC-interfaced test equipment); over-spec for pure sensor/motor roles. | Choose only if USB host/device functionality or >12 KB RAM is mandatory-adds complexity and cost without benefit otherwise. |
Compared with R5F100GJGFB#10, R5F101GJGFB#10 removes data flash to lower cost and simplify programming, while RL78/G14 R5F104GJGFB#10 adds USB and performance headroom at the expense of power efficiency and bill-of-materials simplicity.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GJGFB#10?
The R5F100GJGFB#10 operates at up to 32 MHz with an RL78 CPU core delivering 41 DMIPS. This performance level supports real-time execution of control algorithms, communication stack processing (UART/LIN/I²C), and sensor data fusion without external co-processors. The high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C) eliminates need for external crystals in many applications.
Does the R5F100GJGFB#10 support in-system programming and secure firmware updates?
Yes, the R5F100GJGFB#10 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for firmware security. Self-programming with boot swap function enables safe dual-bank firmware updates, ensuring system availability during field upgrades without risk of corruption.
How does the data flash memory in the R5F100GJGFB#10 differ from standard code flash?
The R5F100GJGFB#10 includes dedicated 8 KB data flash memory rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V, with background operation (BGO) allowing concurrent CPU execution. Unlike code flash, it is optimized for frequent parameter storage, calibration data, and event logging-without disrupting real-time application flow.
What low-power modes are available on the R5F100GJGFB#10, and what is the lowest current consumption?
The R5F100GJGFB#10 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA-enabling multi-year battery operation in sensor nodes. HALT mode draws 66 μA/MHz, providing rapid wake-up (< 4 μs) for responsive event-driven systems.
Can the R5F100GJGFB#10 directly interface with 1.8 V or 2.5 V peripherals?
Yes, the R5F100GJGFB#10 supports different-potential interface operation: its I/O ports can be configured to connect directly to 1.8 V, 2.5 V, or 3 V devices without level shifters. This is enabled by configurable input thresholds and N-ch open-drain outputs with selectable pull-up resistors-simplifying mixed-voltage system design.
