Overview
R5F2135CCNFP#V0 from Renesas is a 16-bit R8C CPU core microcontroller with 128 KB flash program ROM, 10 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). 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. It targets embedded control in consumer audio and office equipment.
For engineers reviewing the R5F2135CCNFP#V0 datasheet, R5F2135CCNFP#V0 pinout, R5F2135CCNFP#V0 application, or R5F2135CCNFP#V0 equivalent, key selection criteria include its 52-pin LQFP package, -20°C to +85°C operating range (N version), integrated LIN transceiver support via UART0 and Timer RA, BGO-enabled data flash for firmware updates without halting execution, and low-power stop mode consuming only 2.0 µA.
Technical Context
The R5F2135CCNFP#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 (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
It features four clock sources: XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator. Peripheral integration includes UART0/1/2 (with I²C mode on UART2), SSU, LIN module, DTC (1 channel, 33 activation sources), and voltage detection with three selectable levels.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F2135CCNFP#V0?
The R5F2135CCNFP#V0 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8 V. This dual-voltage/frequency capability enables flexible power management-high-speed execution during active tasks and lower-frequency, lower-voltage operation in standby states-while maintaining full peripheral functionality across the entire 1.8–5.5 V range.
Does the R5F2135CCNFP#V0 support in-circuit debugging and flash programming?
Yes, the R5F2135CCNFP#V0 includes on-chip debug capability and on-board flash rewrite functionality. It supports standard Renesas E8/E8a debug interfaces, enabling full breakpoint, step-through, and register inspection during development. The background operation (BGO) feature allows flash reprogramming-including data flash updates-without halting CPU execution, critical for field firmware updates in deployed R5F2135CCNFP#V0 systems.
How many analog-to-digital converter channels does the R5F2135CCNFP#V0 provide, and what is their resolution?
The R5F2135CCNFP#V0 integrates a single 10-bit successive-approximation ADC with 12 input channels (AN0–AN11). It supports sweep mode for automatic sequential conversion and includes a sample-and-hold circuit to ensure accurate sampling of fast-changing analog signals-essential for precise sensor interfacing in R5F2135CCNFP#V0-based appliance and audio control applications.
What timer peripherals are available on the R5F2135CCNFP#V0, and which support PWM generation?
The R5F2135CCNFP#V0 includes Timer RA (8-bit, pulse output), Timer RB (8-bit, programmable waveform/PWM), Timer RC (16-bit, 3-PWM), and Timer RD (16-bit ×2, 6-PWM with complementary and synchronous reset modes). Timer RD's complementary PWM capability-supporting three-phase motor drive with dead-time control-is a key differentiator for R5F2135CCNFP#V0 in motion control applications.
Is the R5F2135CCNFP#V0 pin-compatible with other members of the R8C/35C Group?
Yes, all R8C/35C Group MCUs-including R5F2135CCNFP#V0-share the identical 52-pin LQFP (PLQP0052JA-A) package and pin assignment. This enables direct hardware reuse across memory variants (e.g., R5F21358CNFP, R5F2135ACNFP) and temperature grades (e.g., R5F2135CCDFP), simplifying design scalability and inventory management for R5F2135CCNFP#V0-based platforms.
