It operates at up to 20 MHz (VCC = 2.7–5.5 V), features an integrated 10-bit 12-channel A/D converter, dual 8-bit D/A outputs, hardware LIN module, and background operation (BGO) for data flash programming - deployed in consumer audio equipment and office automation control systems.
For engineers reviewing the R5F2136CMNFA#V0 datasheet, R5F2136CMNFA#V0 pinout, R5F2136CMNFA#V0 application, or R5F2136CMNFA#V0 equivalent, key selection criteria include its 64-pin PLQP0064GA-A package, −40°C to +85°C industrial temperature grade (D version), real-time clock (Timer RE), and hardware LIN support via UART0 and Timer RA.
Technical Context
The R5F2136CMNFA#V0 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and a dedicated 16×16→32-bit multiplier with MAC capability. Its memory architecture separates 128 KB program ROM (04000h–23FFFh), 10 KB data flash (03000h–03FFFh), and 6 KB RAM (00400h–01BFFh), all accessible without external bus logic.
Peripheral integration includes six independent timers (RA–RG), three UART/serial interfaces (UART0–2 with I²C mode), SSU, LIN hardware, two comparators, and voltage detection circuits with programmable thresholds - all managed via dedicated SFRs mapped to fixed addresses (0000h–002FFh and 02C00h–02FFFh).

FAQ
What is the maximum operating frequency and supply voltage range for the R5F2136CMNFA#V0?
The R5F2136CMNFA#V0 supports a maximum operating frequency of 20 MHz at VCC = 2.7–5.5 V, and a minimum of 5 MHz at VCC = 1.8–5.5 V. Its wide voltage range enables direct integration with single-cell Li-ion (3.0–4.2 V) or 5 V rail systems without external regulators - critical for compact audio and appliance designs where board space is constrained.
Does the R5F2136CMNFA#V0 support hardware LIN communication, and how is it implemented?
Yes, the R5F2136CMNFA#V0 integrates a hardware LIN module using UART0 and Timer RA to generate accurate baud rates and handle LIN frame formatting. This offloads protocol processing from the CPU, ensuring deterministic timing for automotive body electronics and industrial sensor networks - unlike software-based LIN stacks that consume CPU cycles and introduce jitter.
How does the background operation (BGO) function work in the R5F2136CMNFA#V0 data flash?
The R5F2136CMNFA#V0 supports background operation (BGO) on its 10 KB data flash (4 × 1 KB blocks), allowing erase/write operations to proceed concurrently with CPU code execution. This enables seamless firmware updates or parameter logging without interrupting real-time control loops - a key advantage over MCUs requiring full CPU stall during flash writes.
What are the key low-power modes available on the R5F2136CMNFA#V0, and their typical current consumption?
The R5F2136CMNFA#V0 offers wait mode (3.5 µA @ 3.0 V, 32 kHz XCIN active) and stop mode (2.0 µA @ 3.0 V). Both retain RAM content and allow wake-up via external interrupt or RTC alarm. These ultra-low quiescent currents make the R5F2136CMNFA#V0 suitable for battery-powered remote controls and sensor nodes requiring multi-year operation.
Is the R5F2136CMNFA#V0 pin-compatible with other members of the R8C/36M Group, such as the R5F21368MNFA#V0?
Yes, all R8C/36M Group MCUs in the PLQP0064GA-A package - including R5F2136CMNFA#V0 and R5F21368MNFA#V0 - share identical 64-pin LQFP pinouts and electrical characteristics. Firmware and PCB layouts are interchangeable across the family; only program ROM size (128 KB vs. 64 KB) and data flash capacity differ - simplifying design scalability and inventory management.
