Product details
Overview
R5F2136CCDFA#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 128 KB program ROM, 10 KB data flash (4 × 1 KB blocks), and 10 KB RAM in a 64-pin LQFP (PLQP0064GA-A) package. It operates at up to 20 MHz (VCC = 2.7–5.5 V), integrates 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and six timer units including complementary PWM-capable Timer RD for motor control in consumer appliance power stages.
For engineers reviewing the R5F2136CCDFA#V0 datasheet, R5F2136CCDFA#V0 pinout, R5F2136CCDFA#V0 application, or R5F2136CCDFA#V0 equivalent, key selection criteria include its −40°C to +85°C industrial temperature grade, background operation (BGO) support for data flash reprogramming during runtime, integrated voltage detection with selectable reset thresholds, and hardware LIN 2.1 compliance via UART0 + Timer RA.
Technical Context
The R5F2136CCDFA#V0 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte, with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash mapped to 03000h–03FFFh.
Clock generation includes four independent circuits: XIN (up to 20 MHz crystal), XCIN (32 kHz crystal), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all supporting selectable frequency dividers (1/2/4/8/16) and low-power wait/stop modes with typical current as low as 2.0 µA in stop mode (VCC = 3.0 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2136CCNFA#V0 | N-version (−20°C to +85°C); identical ROM/RAM/peripherals but lower temperature rating | Suitable only for commercial indoor environments without thermal stress | Select when cost sensitivity outweighs extended temperature requirement and ambient stays above −20°C |
| R5F2136ACDFA#V0 | 96 KB program ROM, 8 KB data flash, same package and peripheral set | Reduced firmware capacity limits complex protocol stacks (e.g., full BLE + OTA) | Choose for simpler control tasks where 128 KB ROM is unnecessary and BOM cost reduction is prioritized |
Compared with R5F2136CCDFA#V0, the N-version alternative trades industrial temperature resilience for lower cost, while the 96 KB variant sacrifices firmware headroom to reduce memory silicon area - both retain identical peripheral functionality and pin compatibility for drop-in layout reuse.

FAQ
What is the maximum operating frequency of the R5F2136CCDFA#V0 and under what voltage conditions?
The R5F2136CCDFA#V0 achieves a maximum operating frequency of 20 MHz when supplied at VCC = 2.7–5.5 V. At reduced supply voltages (1.8–5.5 V), the maximum frequency drops to 5 MHz to maintain timing margins and stability. This dual-frequency capability allows flexible power/performance trade-offs in battery-powered or low-voltage subsystems.
Does the R5F2136CCDFA#V0 support in-system programming of its data flash during normal operation?
Yes, the R5F2136CCDFA#V0 supports background operation (BGO) for data flash, enabling erase and write operations to proceed concurrently with application code execution. This feature is essential for implementing over-the-air firmware updates or dynamic parameter storage without system interruption - confirmed in Section 1.1 and Table 1.2 of the R01DS0018EJ0110 datasheet.
How many independent PWM output channels does the R5F2136CCDFA#V0 provide, and which timer units deliver them?
The R5F2136CCDFA#V0 provides up to six independent PWM output channels via Timer RD (16-bit ×2 with 4 capture/compare registers), plus additional PWM from Timer RB (1 channel) and Timer RC (3 channels). Timer RD's complementary PWM mode drives high-side/low-side pairs with configurable dead time - critical for motor inverter gate control.
What peripheral resources does the R5F2136CCDFA#V0 allocate for hardware LIN communication?
The R5F2136CCDFA#V0 implements hardware LIN 2.1 using UART0 for serial framing and Timer RA for precise baud rate timing and sync field generation. This dedicated hardware offloads LIN protocol timing from the CPU, ensuring deterministic frame transmission and reducing software overhead by ~35% compared to bit-banged implementations.
Is the R5F2136CCDFA#V0 pin-compatible with other members of the R8C/36C Group, such as the R5F2136ACDFA#V0?
Yes, the R5F2136CCDFA#V0 is pin-compatible with all R8C/36C Group variants in the PLQP0064GA-A (64-pin LQFP) package, including R5F2136ACDFA#V0 and R5F21365CDFA#V0. Pin assignments, peripheral multiplexing, and electrical characteristics are identical - enabling direct substitution in existing PCB layouts when upgrading firmware capacity or adjusting memory configuration.
