Product details
Overview
R5F2136CSNFP#50 from Renesas is a 16-bit R8C CPU core microcontroller with 128 KB flash program ROM, 10 KB RAM, and integrated touch sensor control unit (TSCU) supporting 28 electrostatic capacitive touch channels. It operates at up to 20 MHz (VCC = 2.7–5.5 V), features 10-bit × 12-channel A/D converter, hardware LIN module, and on-chip data flash (4 × 1 KB blocks) with background operation (BGO). Used in consumer appliance human-interface subsystems requiring low EMI and robust capacitive touch sensing.
For engineers reviewing the R5F2136CSNFP#50 datasheet, R5F2136CSNFP#50 pinout, R5F2136CSNFP#50 application, or R5F2136CSNFP#50 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases for touch-enabled appliances, and two confirmed alternative MCU options with documented functional and packaging differences.
Technical Context
The R5F2136CSNFP#50 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 program ROM allocated across low and high address ranges (e.g., 128 KB at 08000h–27FFFh) and data flash at 07000h–07FFFh.
It integrates four independent clock sources - XIN/XOUT crystal oscillator, XCIN/XCOUT low-power oscillator, high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - with selectable frequency division (1/2/4/8/16) and dedicated watchdog timer oscillator. Peripheral coordination is enabled via Event Link Controller (30 sources × 10 operation types), decoupling event handling from interrupt latency.

FAQ
What is the maximum CPU clock frequency supported by the R5F2136CSNFP#50 and under what voltage conditions?
The R5F2136CSNFP#50 supports a maximum CPU clock frequency of 20 MHz when powered at VCC = 2.7 V to 5.5 V. At lower voltages down to 1.8 V, the maximum guaranteed frequency is reduced to 5 MHz. This dual-voltage/frequency specification allows flexible power-performance trade-offs in battery-powered or wide-input-range applications.
Does the R5F2136CSNFP#50 include hardware support for LIN communication, and how is it implemented?
Yes, the R5F2136CSNFP#50 includes a dedicated hardware LIN module (HW-LIN_0). It operates using UART0_0, UART0_1, or UART2 as its physical layer, offloading protocol framing, checksum generation, and schedule table management from the CPU. This enables deterministic LIN 2.1/2.2 compliance without software bit-banging overhead.
How many capacitive touch channels does the R5F2136CSNFP#50 support, and what peripheral enables this functionality?
The R5F2136CSNFP#50 supports 28 electrostatic capacitive touch channels via its integrated Touch Sensor Control Unit (TSCU). The TSCU handles electrode scanning, noise filtering, and baseline tracking autonomously, reducing CPU load and enabling reliable touch detection even in electrically noisy appliance environments.
What are the data flash capabilities of the R5F2136CSNFP#50, and is background operation supported?
The R5F2136CSNFP#50 includes 4 × 1 KB blocks (total 4 KB) of on-chip data flash with background operation (BGO) support. BGO allows the CPU to execute code from program ROM while simultaneously erasing or programming data flash, enabling seamless firmware updates and parameter storage without system interruption.
What is the operating temperature range for the R5F2136CSNFP#50, and how is this indicated in the part number?
The R5F2136CSNFP#50 is an N-version device rated for −20°C to +85°C operating ambient temperature. This is encoded in the part number suffix "N" - as opposed to "D" for −40°C to +85°C - and corresponds to the PLQP0064KB-A package variant used in consumer-grade applications.
