Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101PFGFB#X0 | No data flash (0 KB); same pinout, package, and peripherals | Not suitable for field-upgradable firmware or parameter storage requiring nonvolatile retention | Select when code-only storage suffices and cost reduction is prioritized over data logging capability |
| RA2A1-RK100FBC0 | 32-bit Arm Cortex-M23, 256 KB flash, 32 KB SRAM, 12-bit ADC (24 ch), 40 MHz max | Higher performance, security features (TrustZone), but higher power (110 μA/MHz) and larger footprint | Choose for next-gen designs needing cryptographic acceleration, richer connectivity, or future scalability beyond RL78 limits |
Compared with R5F100PFGFB#X0, R5F101PFGFB#X0 removes data flash while retaining identical footprint and real-time peripherals-ideal for static firmware deployments; RA2A1-RK100FBC0 offers 32-bit performance and security at higher power and cost, better suited for complex HMI or secure edge node upgrades.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F100PFGFB#X0?
The R5F100PFGFB#X0 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0 %). At this frequency, typical active current is 66 μA per MHz - meaning ~2.1 mA total at 32 MHz with all peripherals enabled. In HALT mode, current drops to 0.32 μA; in STOP mode with RTC + LVD active, it reaches 0.57 μA, enabling decade-scale battery operation in R5F100PFGFB#X0-based sensor nodes.
Does the R5F100PFGFB#X0 support in-application programming (IAP) of its code flash memory?
Yes, the R5F100PFGFB#X0 supports full in-application programming via its on-chip flash self-programming library. It enables erasing and rewriting of code flash blocks (1 KB minimum) while executing from other memory regions, with boot swap functionality for safe firmware updates. The R5F100PFGFB#X0 also includes flash shield window protection to prevent unauthorized access to critical code sections during field deployment.
How many analog input channels does the R5F100PFGFB#X0 ADC support, and what reference options are available?
The R5F100PFGFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external VDD or AVCC as reference, as well as an internal 1.45 V reference voltage - selectable via register configuration. The internal reference enables stable measurements independent of supply variation, and the on-chip temperature sensor (accessible via ANI25) provides calibrated thermal monitoring without external components in R5F100PFGFB#X0 designs.
What low-power modes are available on the R5F100PFGFB#X0, and how do they differ in wake-up capability?
The R5F100PFGFB#X0 offers HALT, STOP, and SNOOZE low-power modes. HALT stops the CPU but keeps peripherals running; wake-up occurs via any interrupt. STOP halts all clocks except RTC and LVD; wake-up sources include RTC alarm, LVD detection, or external pins. SNOOZE allows selected peripherals (e.g., UART, ADC) to operate while CPU sleeps - ideal for periodic sensor polling. All three modes are accessible and configurable in R5F100PFGFB#X0 firmware without external circuitry.
Is the R5F100PFGFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100PFGFB#X0 is fully pin-compatible with all other 100-pin LFQFP RL78/G13 variants (e.g., R5F100PLAFB, R5F101PFGFB#X0), sharing identical pin functions, electrical characteristics, and mechanical footprint. This enables direct substitution within the same package family for memory or feature scaling - for example, upgrading to 256 KB flash (R5F100PKAFB) or downgrading to no data flash (R5F101PFGFB#X0) - without PCB redesign, provided firmware accounts for memory map differences in R5F100PFGFB#X0-based platforms.
