Product details
Overview
R5F2L36CCDFA#31 from Renesas is a 16-bit R8C/L36C Group single-chip microcontroller featuring an R8C CPU core, 128 KB flash program memory, 1 KB × 4 data flash with background operation (BGO), and 10 KB RAM. It delivers 50 ns minimum instruction execution at 20 MHz, integrates a 16×16-bit multiplier, and supports LCD drive (up to 8 COM / 32 SEG pins) for appliance control panels.
For engineers reviewing the R5F2L36CCDFA#31 datasheet, R5F2L36CCDFA#31 pinout, R5F2L36CCDFA#31 application, or R5F2L36CCDFA#31 equivalent, key selection criteria include its 64-pin LQFP package (0.80 mm pitch), -40°C to +85°C industrial temperature grade, integrated LIN module (using Timer RA and UART0), and 10-bit × 10-channel ADC with sample-and-hold.
Technical Context
The R5F2L36CCDFA#31 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit hardware multiplier supporting multiply-accumulate operations. Its system clock generation includes four independent circuits: XIN oscillator (up to 20 MHz), XCIN 32 kHz crystal input, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software-controlled clock switching.
Peripheral integration centers on mixed-signal timing and interface functions: Timer RD provides three-phase PWM with complementary outputs (6 pins), Timer RC offers 3-pin PWM output, and UART2 supports I²C-bus mode alongside standard UART. The DTC (Data Transfer Controller) enables autonomous transfers triggered by 38 sources including ADC completion and serial receive events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L36CCNFA | Same package and peripherals, but rated for -20°C to +85°C (N version) instead of -40°C to +85°C (D version). | Suitable for commercial indoor applications; not qualified for extended industrial or automotive under-hood environments. | Select R5F2L36CCNFA only if ambient operating temperature remains above -20°C and cost sensitivity outweighs thermal margin requirements. |
| R5F2L38CCDFA | Higher I/O count (68 pins vs. 52), 16-channel ADC, 48-segment LCD drive, and 80-pin LQFP package - no pin compatibility. | Required when expanding sensor count, display complexity, or peripheral concurrency beyond R5F2L36CCDFA#31 capabilities. | Choose R5F2L38CCDFA for next-generation designs needing higher integration density; requires PCB redesign due to larger footprint and pinout change. |
Compared with R5F2L36CCDFA#31, the R5F2L36CCNFA trades industrial temperature range for lower cost in benign environments, while the R5F2L38CCDFA provides scalable I/O and analog resources at the expense of board layout compatibility - making R5F2L36CCDFA#31 optimal for cost-sensitive, thermally demanding appliance HMI designs.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F2L36CCDFA#31?
The R5F2L36CCDFA#31 operates at up to 20 MHz when supplied at 2.7–5.5 V, and supports reduced-frequency operation (5 MHz) down to 1.8 V for ultra-low-power scenarios. Its minimum instruction execution time is 50 ns at 20 MHz, enabling responsive real-time control in appliance interfaces and sensor systems.
Does the R5F2L36CCDFA#31 support in-system programming and data retention during rewrites?
Yes, the R5F2L36CCDFA#31 supports in-system programming of both program ROM and data flash. Its data flash endurance is rated for 10,000 erase/write cycles, and the Background Operation (BGO) function allows flash rewriting while application code continues executing - essential for field-upgradable firmware without system interruption.
How many I/O pins does the R5F2L36CCDFA#31 provide, and what types are supported?
The R5F2L36CCDFA#31 provides 52 programmable CMOS I/O pins, including 8 high-current drive ports capable of sourcing/sinking higher loads for direct LED or relay driving. All I/O pins support selectable pull-up resistors and share functions with peripherals such as timers, UART, I²C, and ADC channels - enabling flexible pin multiplexing in space-constrained designs.
What LCD display configurations does the R5F2L36CCDFA#31 support?
The R5F2L36CCDFA#31 supports LCD bias voltages of 1/2, 1/3, or 1/4 and duty cycles of static, 1/2, 1/3, 1/4, or 1/8. It drives up to 8 common and 32 segment outputs, enabling alphanumeric or custom segment displays commonly used in appliance control panels and industrial HMIs without external driver ICs.
Is the R5F2L36CCDFA#31 pin-compatible with other R8C/L3x Group MCUs like the R5F2L35 or R5F2L38 series?
No, the R5F2L36CCDFA#31 is not pin-compatible with R8C/L35C or R8C/L38C Group MCUs. It uses a 64-pin LQFP package (PLQP0064GA-A), whereas the L35C Group uses 52-pin LQFP and the L38C Group uses 80-pin LQFP. Pin assignments, I/O counts, and peripheral mappings differ significantly across groups - requiring unique PCB layouts for each family member.
