Overview
R5F12067ASP#50 from Renesas Electronics is a 20-pin RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB data flash, and 1 KB RAM, operating at 2.4–5.5 V. It integrates an 8/10-bit 11-channel ADC, dual comparators, 8-channel 16-bit timer array, UART, two simplified I²C interfaces, and two CSI (SPI-compatible) channels - deployed in industrial sensor nodes and low-power motor control.
For engineers reviewing the R5F12067ASP#50 datasheet, R5F12067ASP#50 pinout, R5F12067ASP#50 application, or R5F12067ASP#50 equivalent, key selection criteria include its 20-pin LSSOP package, −40°C to +105°C industrial temperature grade (G), 4 KB flash capacity, dual comparator support, and on-chip debug capability with BGO-disabled data flash rewriting.
Technical Context
The R5F12067ASP#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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 erase), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 1 KB SRAM - all accessible under single-supply operation.
Peripherals are organized around a unified interrupt controller supporting 19 vectored sources (8 external), a TAU0 timer array with 8 channels and PWM output capability, dual independent comparators (IVCMP0/IVCMP1 with selectable internal/external reference), and serial interfaces including UART0, IICA0, CSI00, and CSI01 - all mapped to dedicated pins in the 20-pin LSSOP footprint with full peripheral I/O redirection via PIOR registers.

FAQ
What is the maximum operating frequency of the R5F12067ASP#50?
The R5F12067ASP#50 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. External crystal oscillation up to 12 MHz is also supported via X1/X2 pins. The actual achievable frequency depends on VDD (2.4–5.5 V) and ambient temperature (−40°C to +105°C).
Does the R5F12067ASP#50 support background data flash rewriting?
No, the R5F12067ASP#50 does not support background operation (BGO) for data flash rewriting. During data flash write/erase operations, instruction execution from code flash memory is halted. This requires careful firmware sequencing to avoid system lockup - typically handled via interrupt-driven state machines that pause main loop execution.
How many analog input channels does the R5F12067ASP#50 provide?
The R5F12067ASP#50 provides 11 analog input channels (ANI0 through ANI10), supporting 8/10-bit resolution ADC conversion with internal 0.815 V reference voltage. All channels are accessible on the 20-pin LSSOP package, with ANI0–ANI3 on Port 0 and ANI7–ANI10 on Port 2.
What is the purpose of the PCLBUZ0 pin on the R5F12067ASP#50?
The PCLBUZ0 pin on the R5F12067ASP#50 serves as a programmable clock/buzzer output capable of generating frequencies up to 10 MHz. It can drive piezoelectric buzzers directly or provide precise clock signals to external peripherals - eliminating the need for discrete oscillators in timing-critical or audio-feedback applications.
Is the R5F12067ASP#50 pin-compatible with other RL78/G15 variants in the 20-pin LSSOP package?
Yes, the R5F12067ASP#50 is fully pin-compatible with all RL78/G15 20-pin LSSOP variants including R5F12068ASP#50, R5F12067GSP#50, and R5F12068GSP#50. They share identical pin configuration, electrical characteristics, and peripheral mapping - enabling seamless migration based on flash size or temperature grade requirements.
