Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F12048GSP#50 | 8 KB code flash (vs. 4 KB), identical pinout, package, peripherals, and temperature grade. | Required when firmware exceeds 4 KB or future-proofing for feature expansion is needed. | Select R5F12048GSP#50 if code size growth is anticipated; no PCB or firmware changes required beyond flash layout adjustment. |
| R5F12047MSP#50 | Same 4 KB flash, 1 KB RAM, and peripherals but rated for TA = −40°C to +125°C (M-grade). | Necessary for under-hood automotive or high-temperature industrial enclosures exceeding +105°C ambient. | Choose R5F12047MSP#50 only when operating above +105°C; otherwise, G-grade offers optimal cost/performance balance. |

FAQ
What is the maximum operating frequency of the R5F12047GSP#50?
The R5F12047GSP#50 supports a maximum system clock frequency of 16 MHz using its high-speed on-chip oscillator. This yields a minimum instruction execution time of 0.0625 μs. External crystal (X1/X2) or EXCLK input up to 12 MHz or 16 MHz respectively is also supported, but the on-chip oscillator eliminates external components for most industrial applications. The R5F12047GSP#50 maintains full functionality across its entire −40°C to +105°C industrial temperature range at this speed.
Does the R5F12047GSP#50 support in-application programming (IAP) of its code flash memory?
Yes, the R5F12047GSP#50 supports self-programming of code flash memory without requiring a boot swap function. Firmware updates can be performed in-system by executing code from RAM while erasing and rewriting flash blocks (1 KB each). The R5F12047GSP#50 includes flash shield window protection to prevent unauthorized access, and erase/write operations require proper command sequences and voltage supervision (VDD = 2.4–5.5 V).
How many analog input channels does the R5F12047GSP#50 provide, and what is their resolution?
The R5F12047GSP#50 provides 7 analog input channels (ANI0–ANI6) with configurable 8-bit or 10-bit resolution. It includes an internal reference voltage of 0.815 V (typical), enabling accurate measurements without external references. Input voltage range is 0 to VDD (2.4–5.5 V), and conversions can be triggered by software, timer, or external events-supporting background operation for continuous sensor monitoring.
What debug interface does the R5F12047GSP#50 use, and what pins are required?
The R5F12047GSP#50 uses Renesas' on-chip debug interface accessed via three dedicated pins: TOOL0 (debug data I/O), TOOLRxD (receive), and TOOLTxD (transmit). These share functions with P40, P01, and P00 respectively, allowing full debugging-including breakpoints, register inspection, and flash programming-without external emulators. The R5F12047GSP#50 does not require SWD or JTAG connectors, simplifying PCB layout and reducing system cost.
Is the R5F12047GSP#50 pin-compatible with other RL78/G15 variants in the same package?
Yes, the R5F12047GSP#50 is fully pin-compatible with all other 16-pin SSOP RL78/G15 devices, including R5F12048GSP#50 (8 KB flash), R5F12047MSP#50 (M-grade temp), and R5F12047ASP#50 (A-grade). All share identical pin functions, electrical characteristics, and footprint (PRSP0016JC-B). Firmware and hardware designs can be reused across these variants-only flash size and temperature grade differ, enabling scalable product families with minimal redesign effort.
