It targets battery-powered industrial sensors and motor control modules requiring low-power operation at high ambient temperatures.
For engineers reviewing the R5F12067MSP#30 datasheet, R5F12067MSP#30 pinout, R5F12067MSP#30 application, or R5F12067MSP#30 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases for high-temp embedded systems, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The R5F12067MSP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting minimum instruction execution time of 0.0625 μs at 16 MHz using the high-speed on-chip oscillator. Its memory subsystem includes 4 KB code flash (1 KB block size), 1 KB data flash (512 B block, 1M rewrite cycles), and 1 KB on-chip RAM.
It integrates 8-channel 16-bit timer array (TAU0), 12-bit interval timer, watchdog timer, and dual analog comparators with selectable internal/external reference voltage. Serial connectivity comprises one UART channel, two simplified I²C (IIC00/IIC01), two CSI (SPI-compatible) channels, and IICA0 for standard I²C bus communication.

FAQ
What is the maximum operating temperature supported by the R5F12067MSP#30?
The R5F12067MSP#30 is rated for industrial operation from −40°C to +125°C (M-grade qualification), making it suitable for under-hood automotive modules, industrial motor drives, and high-temperature sensor nodes where standard commercial-grade MCUs would fail.
Does the R5F12067MSP#30 support hardware-based PWM generation?
Yes, the R5F12067MSP#30 integrates an 8-channel 16-bit timer array (TAU0) capable of generating up to 7 independent PWM outputs. These outputs are mapped to pins including TO00, TO01, TO02, TO03, TO04, TO05, and TO07-enabling precise motor speed control and LED dimming without CPU intervention.
How many analog input channels does the R5F12067MSP#30 provide?
The R5F12067MSP#30 provides 11 analog input channels (ANI0 through ANI10), supporting both 8-bit and 10-bit A/D conversion with a selectable internal 0.815 V reference voltage or external reference sources-ideal for multi-sensor industrial monitoring systems.
Can the R5F12067MSP#30 operate from a single 3.3 V supply?
Yes, the R5F12067MSP#30 operates across a wide 2.4 V to 5.5 V supply range, fully supporting standard 3.3 V logic systems. Its IOH/IOL drive strength remains specified across this range, ensuring reliable interfacing with 3.3 V peripherals without level shifters.
Is on-chip debug functionality available on the R5F12067MSP#30?
Yes, the R5F12067MSP#30 includes full on-chip debug support via TOOL0, TOOLRxD, and TOOLTxD pins, enabling real-time firmware debugging and flash programming during development-though Renesas advises against using this function in mass-produced end products due to flash endurance limits.
