Product details
Overview
R5F12018MSP#70 from Renesas Electronics is an RL78/G15 10-pin LSSOP microcontroller with 8 KB code flash, 1 KB RAM, and 1 KB data flash, operating from 2.4 V to 5.5 V across −40°C to +125°C. It integrates an 8/10-bit ADC (4 channels), two simplified I²C interfaces, one UART, two CSI (SPI-compatible) channels, eight 16-bit timer channels, and a high-speed on-chip oscillator selectable from 1–16 MHz ±1.0% (−20°C to +85°C). It targets industrial motor control and sensor interface modules requiring robust thermal operation and low-power HALT/STOP modes.
For engineers reviewing the R5F12018MSP#70 datasheet, R5F12018MSP#70 pinout, R5F12018MSP#70 application, or R5F12018MSP#70 equivalent, key selection criteria include its M-grade temperature rating (+125°C), 10-pin LSSOP package with 0.65-mm pitch, dual simplified I²C support, integrated programmable clock/buzzer output (PCLBUZ0), and absence of background data flash rewriting capability.
Technical Context
The R5F12018MSP#70 implements the RL78-S2 CPU core-a CISC architecture with 3-stage pipeline and 1 MB address space-enabling minimum instruction execution time of 0.0625 μs at 16 MHz. Its memory subsystem includes 8 KB code flash (1 KB block size, erase-before-write only) and 1 KB data flash (512 B blocks, 1,000,000 TYP. rewrites at VDD = 2.4–5.5 V).
Power management includes selectable power-on-reset (SPOR) with four voltage thresholds, HALT and STOP low-power modes, and dual on-chip oscillators: high-speed (1–16 MHz) and low-speed (15 kHz). Peripheral integration centers on timer array unit (TAU0) with eight 16-bit channels, SAU0 serial array unit supporting UART, CSI, and simplified I²C, and analog functions including comparator (1 channel) and 8/10-bit ADC with internal 0.815 V reference.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F12018MSP#70?
The R5F12018MSP#70 features a high-speed on-chip oscillator selectable from 1 MHz to 16 MHz. Its frequency accuracy is ±1.0% over −20°C to +85°C ambient, ±1.5% over −40°C to −20°C and +85°C to +125°C, and ±2.0% over the full −40°C to +85°C range for consumer-grade variants. This specification applies directly to the R5F12018MSP#70 under M-grade industrial qualification.
Does R5F12018MSP#70 support background data flash rewriting while executing code from main flash?
No, the R5F12018MSP#70 does not support background operation (BGO) for data flash rewriting. During data flash write or erase operations, instruction execution from code flash memory is halted. This behavior is explicitly documented in the datasheet: "Background operation (BGO) is not supported (instructions cannot be executed from the code flash memory while rewriting the data flash memory)" - a critical constraint for real-time firmware updates in the R5F12018MSP#70.
How many analog input channels does R5F12018MSP#70 provide, and what is the reference voltage option?
The R5F12018MSP#70 provides four analog input channels (ANI0–ANI3) with 8/10-bit resolution. It supports VDD as the ADC reference and includes an internal reference voltage of 0.815 V (TYP.), accessible via IVREF0 on P04. This internal reference enables stable ADC measurements independent of supply rail fluctuations - a key capability confirmed for the R5F12018MSP#70 in the RL78/G15 datasheet Section 1.1.
What serial communication interfaces are integrated into R5F12018MSP#70?
The R5F12018MSP#70 integrates one UART channel (RxD0/TxD0), two simplified I²C interfaces (IIC00 and IIC01), and two CSI channels (CSI00 and CSI01), where CSI is Renesas' term for SPI-compatible serial interface. These are implemented via shared pins including P00–P04 and P02–P03, with multiplexing controlled by the peripheral I/O redirection register (PIOR) - fully documented for the R5F12018MSP#70 in the RL78/G15 User's Manual.
Is R5F12018MSP#70 pin-compatible with other RL78/G15 10-pin variants such as R5F12017MSP#70?
Yes, the R5F12018MSP#70 is pin-compatible with R5F12017MSP#70: both use the identical 10-pin LSSOP package, share identical pin configuration (Table 1-3), and support the same peripheral multiplexing scheme. The sole functional difference is code flash capacity (8 KB vs. 4 KB); all I/O, timer, ADC, and communication resources map identically - enabling drop-in replacement where firmware size permits, as verified in the RL78/G15 datasheet Section 1.3.2 and Table 1-1.
