Product details
Overview
R5F12067MSP#50 from Renesas Electronics is a 20-pin, 4 KB code flash, 1 KB RAM RL78/G15 16-bit microcontroller with industrial-grade temperature range (−40°C to +125°C), 8/10-bit A/D converter (11 channels), dual comparators, and integrated UART, simplified I²C, and CSI serial interfaces. It operates from a single 2.4–5.5 V supply and supports HALT/STOP low-power modes for battery-powered sensor nodes and motor control subsystems.
For engineers reviewing the R5F12067MSP#50 datasheet, R5F12067MSP#50 pinout, R5F12067MSP#50 application, or R5F12067MSP#50 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts - all grounded in Renesas' official R01DS0420EJ0140 Rev.1.40 documentation.
Technical Context
The R5F12067MSP#50 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction execution time (0.0625 μs at 16 MHz to 1.0 μs at 1 MHz). It integrates an on-chip high-speed oscillator (1–16 MHz, ±1.0% accuracy at −20°C to +85°C) and low-speed oscillator (15 kHz), plus selectable power-on-reset circuitry with four voltage thresholds (2.25–4.45 V).
Its peripheral set includes eight 16-bit timer channels (supporting PWM output), one 12-bit interval timer, one watchdog timer, and dual analog comparators with internal/external reference selection. The device supports background operation only for code flash erase/write (not data flash), and lacks BGO during data flash rewriting - instructions cannot execute from code flash while data flash is being rewritten.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F12068MSP#50 | 8 KB code flash (vs. 4 KB), identical pinout, package, and peripheral set. | Required when firmware exceeds 4 KB or future OTA updates demand headroom. | Select R5F12068MSP#50 if application requires >4 KB of executable code or long-term firmware scalability. |
| RL78/G14 R5F11AGGFP#50 | Same RL78 core, 20-pin SSOP, but only 2 KB flash, no data flash, and 8-channel A/D (vs. 11). | Suitable for cost-sensitive, function-limited controls where data logging or multi-sensor support is unnecessary. | Choose R5F11AGGFP#50 only for ultra-low-cost implementations with ≤2 KB code and no data retention requirements. |
Compared with R5F12067MSP#50, R5F12068MSP#50 offers double code flash capacity without layout changes, while R5F11AGGFP#50 sacrifices flash, data flash, and A/D channels to reduce unit cost - making it viable only in highly constrained, non-upgradable designs.

FAQ
What is the maximum operating frequency and instruction execution time of the R5F12067MSP#50?
The R5F12067MSP#50 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. This timing is achievable with the high-speed oscillator enabled and system clock configured for full-speed operation - confirmed in Section 1.1 of the R01DS0420EJ0140 datasheet.
Does the R5F12067MSP#50 support background operation during data flash rewriting?
No, the R5F12067MSP#50 does not support background operation (BGO) during data flash rewriting. As stated in the datasheet, instructions cannot be executed from code flash memory while data flash is being rewritten - requiring careful state management and interrupt masking during write sequences.
How many analog input channels does the R5F12067MSP#50 provide, and what is their resolution?
The R5F12067MSP#50 provides 11 analog input channels (ANI0 through ANI10) with selectable 8-bit or 10-bit resolution. This is explicitly documented in Table 1-5 and Section 1.6 of the R01DS0420EJ0140 datasheet, confirming full utilization of the 20-pin LSSOP package's analog-capable pins.
What are the key differences between the R5F12067MSP#50 and R5F12068MSP#50?
The R5F12067MSP#50 contains 4 KB of code flash memory, whereas the R5F12068MSP#50 contains 8 KB - with identical pinout, package, peripherals, and temperature rating. Both share the same 1 KB RAM and 1 KB data flash, making R5F12068MSP#50 a direct capacity upgrade path without hardware redesign.
Is the R5F12067MSP#50 qualified for automotive applications?
The R5F12067MSP#50 carries the "M" suffix denoting industrial qualification (−40°C to +125°C), not AEC-Q100 automotive qualification. While its temperature range meets under-hood requirements, Renesas does not list it in AEC-Q100-certified product families - users requiring automotive qualification must select designated AEC-Q100 parts such as RL78/F14 series.
