Product details
Overview
R5F12068MSP#30 from Renesas Electronics is an 8 KB flash, 1 KB RAM RL78/G15 20-pin LSSOP microcontroller with industrial-grade −40°C to +125°C operation, 8/10-bit 11-channel ADC, dual comparators, and integrated UART, CSI, and I²C interfaces. It targets embedded control in motor drives, sensor nodes, and industrial HMI where low-power operation (54 µA/MHz) and high-temperature reliability are critical.
For engineers reviewing the R5F12068MSP#30 datasheet, R5F12068MSP#30 pinout, R5F12068MSP#30 application, or R5F12068MSP#30 equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in Renesas' official R01DS0420EJ0140 Rev.1.40 documentation.
Technical Context
The R5F12068MSP#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.0625 µs (16 MHz) to 1.0 µs (1 MHz). Its clock system integrates a high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C), low-speed 15 kHz oscillator, and external crystal support (X1/X2, 1–12 MHz).
It features an 8-channel 16-bit timer array (TAU0), 12-bit interval timer, watchdog timer, and programmable clock/buzzer output (PCLBUZ0). Memory includes 8 KB code flash (1 KB block size), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 1 KB SRAM - all operating across VDD = 2.4–5.5 V.

The R5F12068MSP#30 is qualified for industrial applications with a maximum operating ambient temperature of +125°C (M-grade), as specified in the R01DS0420EJ0140 datasheet. This rating applies across the full VDD range of 2.4 V to 5.5 V and enables deployment in sealed enclosures, motor drives, and under-hood industrial systems where thermal margins are constrained.
Does the R5F12068MSP#30 support in-system programming of its flash memory?
Yes, the R5F12068MSP#30 supports self-programming of both code flash and data flash memory without requiring a boot swap function. The device includes an on-chip debug interface (TOOL0/TOOLRxD/TOOLTxD) and flash shield window function, enabling secure field firmware updates and parameter reconfiguration during normal operation - confirmed in Section 1.1 of R01DS0420EJ0140.
How many analog-to-digital converter channels does the R5F12068MSP#30 have?
The R5F12068MSP#30 integrates an 8/10-bit resolution A/D converter with 11 analog input channels (ANI0 through ANI10), as documented in Table 1-5 and Section 1.6 of R01DS0420EJ0140. These channels support internal reference voltage (0.815 V TYP.) and can be sampled simultaneously or sequentially depending on configuration.
What communication interfaces are available on the R5F12068MSP#30?
The R5F12068MSP#30 provides UART (1 channel), simplified SPI (CSI, 2 channels), simplified I²C (2 channels), and full I²C (1 channel), as detailed in Section 1.1 and Table 1-5 of R01DS0420EJ0140. Pin multiplexing allows flexible allocation - for example, P06/P07 support SDA01/SCL01 for secondary I²C, while P02/P03/P04 enable CSI00 with SCK00/SI00/SO00.
Is the R5F12068MSP#30 pin-compatible with other RL78/G15 variants in the same package?
Yes, the R5F12068MSP#30 is fully pin-compatible with other 20-pin LSSOP RL78/G15 devices including R5F12067MSP#30, R5F12068GSP#30, and R5F12068ASP#30. All share identical pin functions, electrical characteristics, and mechanical footprint per Figure 1-1 and Table 1-1 in R01DS0420EJ0140 - enabling direct substitution where flash size or temperature grade permits.
