Product details
Overview
R5F2135AMNFP#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 96 KB flash program memory, 8 KB data flash (4 × 1 KB blocks), and 8 KB RAM, operating at up to 20 MHz (VCC = 2.7–5.5 V). It integrates UART0/1/2, I²C-bus, LIN hardware module, 10-bit × 12-channel ADC, dual 8-bit DACs, six timer units (RA–RE + RD dual-channel), and background operation (BGO) for in-application reprogramming - deployed in consumer audio equipment and office automation control systems.
For engineers reviewing the R5F2135AMNFP#V0 datasheet, R5F2135AMNFP#V0 pinout, R5F2135AMNFP#V0 application, or R5F2135AMNFP#V0 equivalent, key selection criteria include its 52-pin LQFP package, -20°C to +85°C temperature grade (N version), integrated LIN transceiver support via UART0 + Timer RA, BGO-enabled data flash for firmware updates, and low-power stop mode (2.0 µA).
Technical Context
The R5F2135AMNFP#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 independent clock sources: XIN (up to 20 MHz crystal/resonator), XCIN (32 kHz crystal), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - all selectable via CM0/CM1 registers and supporting wait/stop modes with oscillation stop detection.

Does the R5F2135AMNFP#V0 support in-application programming of its data flash memory?
Yes, the R5F2135AMNFP#V0 supports Background Operation (BGO) for data flash, allowing the CPU to execute code from program ROM while erasing or programming any of its four 1 KB data flash blocks. This enables safe firmware parameter updates or logging without system interruption.
How many analog-to-digital converter channels does the R5F2135AMNFP#V0 integrate, and what is their resolution?
The R5F2135AMNFP#V0 integrates a single 10-bit successive-approximation ADC with 12 input channels (AN0–AN11), featuring sample-and-hold circuitry and sweep mode for automatic channel sequencing - sufficient for monitoring multiple sensors in appliances or motor feedback systems.
What peripheral interfaces are available on the R5F2135AMNFP#V0 for industrial communication protocols?
The R5F2135AMNFP#V0 provides UART0/1/2 (with UART2 supporting I²C-bus mode), SSU, and a hardware LIN module (using UART0 + Timer RA). These enable direct implementation of LIN 2.0/2.1 networks, I²C sensor buses, and RS-232/485 gateways without external level translators or protocol accelerators.
Is the R5F2135AMNFP#V0 pin-compatible with other members of the R8C/35M Group?
Yes, all R8C/35M Group MCUs - including R5F21354MNFP through R5F2135CMNFP - share the identical 52-pin LQFP (PLQP0052JA-A) package and pin assignment. Firmware and PCB layouts are interchangeable across memory variants, simplifying design reuse and product family scaling.
