Product details
Overview
R5F12047MSP#70 from Renesas Electronics is a 16-pin, industrial-grade RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB RAM, and 1 KB data flash. It operates from 2.4 V to 5.5 V, supports −40°C to +125°C ambient temperature (M-grade), and integrates an 8-channel 16-bit timer array, 7-channel 8/10-bit ADC, and dual simplified I²C/SPI interfaces - deployed in motor control modules for HVAC actuators.
For engineers reviewing the R5F12047MSP#70 datasheet, R5F12047MSP#70 pinout, R5F12047MSP#70 application, or R5F12047MSP#70 equivalent, key selection criteria include its M-grade thermal rating, SSOP-16 package compatibility, 7-channel analog input capability, and absence of background data flash rewrite support - critical for deterministic firmware updates in safety-critical embedded systems.
Technical Context
The R5F12047MSP#70 implements the RL78 CPU core with a 3-stage CISC pipeline, enabling minimum instruction execution at 0.0625 μs (16 MHz high-speed on-chip oscillator). Its clock system combines selectable high-speed (1–16 MHz) and low-speed (15 kHz) on-chip oscillators, plus external crystal (X1/X2) or EXCLK input up to 12 MHz.
Peripheral integration includes TAU0 timer array (8 channels), SAU0 serial array unit (2 channels supporting CSI/I²C/UART), and dual comparators with internal/external reference selection. All I/O pins support N-ch open-drain output with VDD-tolerant capability and configurable pull-up resistors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F12048MSP#70 | 8 KB code flash (vs. 4 KB), same package, identical peripherals and pinout | Required when firmware exceeds 4 KB or future-proofing for feature expansion is needed | Select R5F12048MSP#70 only if additional flash capacity is confirmed necessary - no runtime or thermal difference |
| RL78/G14 R5F11AGJFP#30 | 16-pin LQFP, 8 KB flash, 1.25 KB RAM, but lacks data flash and simplified I²C support | Suitable for cost-sensitive designs where data logging is handled externally or not required | Choose only if external EEPROM is already present and 125°C operation is not mandatory - G14 lacks M-grade qualification |
Compared with R5F12047MSP#70, R5F12048MSP#70 offers headroom for firmware growth without changing PCB layout, while RL78/G14 R5F11AGJFP#30 trades data flash and enhanced I²C for lower cost and higher RAM - but sacrifices guaranteed 125°C operation and integrated nonvolatile parameter storage.

FAQ
What is the maximum operating frequency of the R5F12047MSP#70?
The R5F12047MSP#70 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. External crystal or EXCLK input up to 12 MHz is also supported. The actual sustained frequency depends on VDD (2.4–5.5 V) and ambient temperature (−40°C to +125°C).
Does the R5F12047MSP#70 support background data flash rewriting?
No, the R5F12047MSP#70 does not support background operation (BGO) for data flash. During data flash rewrite, code execution from code flash memory is halted. This requires careful state management in firmware - the R5F12047MSP#70 must enter a safe idle state before initiating writes.
How many analog input channels does the R5F12047MSP#70 provide?
The R5F12047MSP#70 provides 7 analog input channels (ANI0–ANI6), compatible with 8/10-bit resolution A/D conversion across the full VDD range (2.4–5.5 V). Internal reference voltage (0.815 V TYP.) is available for comparator use but not for ADC reference - ADC uses VDD as default reference.
What package type and pin count does the R5F12047MSP#70 use?
The R5F12047MSP#70 uses a 16-pin plastic SSOP package (4.4 × 5.0 mm, 0.65-mm pitch), designated by "SP" in the part number. It is distinct from the HWQFN variant (NA suffix) and shares pin compatibility with other RL78/G15 16-pin SSOP variants like R5F12048MSP#70.
Is the R5F12047MSP#70 qualified for automotive applications?
The R5F12047MSP#70 is rated for industrial applications (M-grade, −40°C to +125°C) but is not AEC-Q100 qualified. It is suitable for under-hood industrial equipment and consumer appliances operating within its thermal and reliability envelope - however, automotive safety-critical systems require AEC-Q100-certified alternatives.
