FAQ
What is the maximum operating frequency and supply voltage range for the R5F2136CMNFP#30?
The R5F2136CMNFP#30 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation (5 MHz) down to 1.8 V. This dual-voltage capability allows deployment in both 3.3 V and 5 V systems while maintaining real-time responsiveness in motor control and audio processing tasks. The high-speed on-chip oscillator provides clock source flexibility without external components.
Does the R5F2136CMNFP#30 support hardware LIN communication, and how is it implemented?
Yes, the R5F2136CMNFP#30 includes a dedicated hardware LIN module compliant with LIN 2.1, implemented using UART0 and Timer RA. This combination handles LIN frame generation, checksum calculation, and synchronization without CPU intervention. The R5F2136CMNFP#30 thus serves as a LIN slave node in automotive body electronics or smart appliance networks, reducing firmware complexity and improving protocol reliability.
How does the data flash architecture of the R5F2136CMNFP#30 support firmware updates in the field?
The R5F2136CMNFP#30 features 10 KB of data flash organized in four 1 KB blocks with Background Operation (BGO) support. During BGO, the CPU executes application code from program ROM while simultaneously erasing or programming data flash - enabling seamless over-the-air or USB-based firmware updates without system interruption. This capability is critical for maintaining uptime in deployed audio or appliance systems.
What timer resources does the R5F2136CMNFP#30 provide for motor control applications?
The R5F2136CMNFP#30 integrates Timer RD (16-bit ×2) with six PWM output pins and complementary PWM mode for three-phase waveform generation, plus Timer RG with phase counting mode for 2-phase encoder inputs. These timers deliver precise timing for BLDC commutation, current sensing synchronization, and rotor position tracking - all within a single R5F2136CMNFP#30 device without external timing ICs.
Is the R5F2136CMNFP#30 pin-compatible with other members of the R8C/36M Group?
Yes, the R5F2136CMNFP#30 shares identical pinout and package (PLQP0064KB-A) with all other R8C/36M Group MCUs in the MNFP/MNFA/MDFP/MDFA families. Firmware and hardware designs targeting R5F21364MNFP through R5F2136CMNFP can be reused across memory variants, simplifying platform development and enabling scalable product tiers based on code size requirements.
