Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GFGFB#V0 | Same package and pinout; 96 KB flash, 8 KB data flash, 8 KB RAM - reduced code capacity | Suitable where firmware footprint < 96 KB; identical peripheral set and low-power behavior | Select when application code size fits within 96 KB and cost optimization is prioritized |
| R5F101GGGFB#V0 | Same package and pinout; no data flash (0 KB), 128 KB flash, 8 KB RAM - lacks BGO and flash shield window | Applicable where runtime parameter storage is handled externally or not required | Choose when data logging or field firmware updates are unnecessary and lowest bill-of-materials cost is critical |
Compared with R5F100GGGFB#V0, R5F100GFGFB#V0 trades flash capacity for lower unit cost without altering power or peripheral capabilities, while R5F101GGGFB#V0 removes data flash entirely - simplifying security but eliminating embedded nonvolatile parameter storage.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100GGGFB#V0?
The R5F100GGGFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level is sustained across its full 1.6–5.5 V supply range and –40°C to +105°C temperature envelope, making R5F100GGGFB#V0 suitable for deterministic real-time control tasks in demanding environments.
Does the R5F100GGGFB#V0 include an integrated temperature sensor, and how is it accessed?
Yes, the R5F100GGGFB#V0 includes an on-chip temperature sensor accessible via the 10-bit ADC channel ANI25. It requires enabling the sensor in the ADC control register and selecting the internal temperature reference; calibration data is stored in ROM and must be applied in firmware. The sensor is functional only in HS (high-speed main) mode, and R5F100GGGFB#V0's datasheet specifies ±3°C accuracy over the full industrial temperature range.
How does the data flash memory in the R5F100GGGFB#V0 support firmware updates without interrupting system operation?
The R5F100GGGFB#V0's 8 KB data flash supports Background Operation (BGO), allowing the CPU to execute instructions from program flash while simultaneously erasing or programming data flash sectors. This enables safe over-the-air or local firmware updates and parameter logging without halting real-time tasks - a capability confirmed in the R5F100GGGFB#V0's flash self-programming library documentation and verified in application note R20UT2944.
What packaging and lead pitch does the R5F100GGGFB#V0 use, and is it compatible with standard reflow profiles?
The R5F100GGGFB#V0 uses a 48-pin LFQFP package with 7 mm × 7 mm body and 0.5 mm lead pitch. It complies with JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for standard Pb-free reflow soldering per IPC/JEDEC J-STD-020. The #V0 suffix indicates tray packaging, and R5F100GGGFB#V0's thermal pad (if present) is not electrically connected - consistent with Renesas' PLQP0048KF-A package specification.
Can the R5F100GGGFB#V0 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F100GGGFB#V0 supports operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, the RL78 core, 128 KB flash, 8 KB data flash, 8 KB RAM, 10-bit ADC (with internal 1.45 V reference), RTC, 16-bit timers, and all serial interfaces (UART, I²C, CSI) remain fully functional. However, the high-speed on-chip oscillator is limited to ≤8 MHz below 2.7 V - so R5F100GGGFB#V0's maximum frequency at 1.8 V is 8 MHz unless an external clock is supplied.
