Product details
Overview
R5F51136AGFP#3A from Renesas is a 32-bit RX113 Group microcontroller with 256 KB flash, 32 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS) across –40 to +105°C. It integrates USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D, dual 12-bit D/A, LCD controller (40×4), capacitive touch sensing (12 channels), RTC, and low-power modes including 0.44 µA software standby.
For engineers reviewing the R5F51136AGFP#3A datasheet, R5F51136AGFP#3A pinout, R5F51136AGFP#3A application, or R5F51136AGFP#3A equivalent, this page delivers verified functional scope, package-specific peripheral availability, power-performance tradeoffs, and direct alternative options for industrial HMI, portable medical devices, and USB-connected sensor nodes.
Technical Context
The R5F51136AGFP#3A implements the 32-bit RX CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions-enabling 50 DMIPS at 32 MHz. Its on-chip clock system includes high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, USB-dedicated PLL, and CAC for IEC 60730 compliance.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables inter-module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports four transfer modes with interrupt-source mapping. The MCU supports full USB 2.0 OTG with BC (Battery Charger) detection and isochronous transfer capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51136ADFP#3A | Same core, flash, RAM, and peripherals-but rated for –40 to +85°C (D-grade) instead of +105°C | Suitable for commercial/industrial ambient environments without extended thermal stress | Select when operating temperature stays below +85°C and cost optimization is prioritized over extended grade qualification |
| R5F51137AGFP#3A | 384 KB flash, 64 KB SRAM, identical package and temperature rating; same peripheral set | Required where larger firmware image size or additional RAM for complex USB stacks or GUI buffers is needed | Choose when firmware growth exceeds 256 KB or real-time data buffering demands >32 KB SRAM |
Compared with R5F51136AGFP#3A, the D-grade variant trades extended temperature support for lower cost, while the 384 KB variant adds memory headroom without altering thermal or peripheral capabilities-making both viable alternatives depending on thermal envelope and firmware scale requirements.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51136AGFP#3A?
The R5F51136AGFP#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. This is achieved through its 32-bit RX CPU core with five-stage pipeline, variable-length instruction set, and on-chip 32-bit multiplier/divider. Performance is sustained across the full –40 to +105°C operating range, with no derating required at high temperature.
Does the R5F51136AGFP#3A support USB On-The-Go (OTG) and Battery Charging (BC) detection?
Yes, the R5F51136AGFP#3A integrates a full-featured USB 2.0 host/function/OTG module supporting full-speed (12 Mbps), low-speed (1.5 Mbps), isochronous transfer, and BC (Battery Charger) detection per USB BC 1.2 specification. Hardware-level BC detection identifies SDP, CDP, and DCP sources without firmware polling-enabling reliable charging in portable R5F51136AGFP#3A-based designs.
How many analog input channels does the R5F51136AGFP#3A include, and what is its A/D conversion speed?
The R5F51136AGFP#3A includes 17 analog input channels for its 12-bit successive approximation register (SAR) A/D converter. Minimum conversion time is 1.0 µs per channel when ADCLK runs at 32 MHz. It supports scan modes (single, continuous, group), double-trigger mode for motor control synchronization, and multiple start sources including software, MTU timers, external pins, and ELC events.
What low-power modes are available on the R5F51136AGFP#3A, and what is the lowest supply current?
The R5F51136AGFP#3A offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, supply current drops to 0.44 µA (typical) while retaining SRAM content and enabling wake-up via LPT, RTC, or external interrupts. Recovery time from software standby is 4.8 µs, and the Low Power Timer (LPT) continues operating using the sub-clock or IWDT oscillator.
Is the R5F51136AGFP#3A pin-compatible with other RX113 Group MCUs in the same package?
Yes, the R5F51136AGFP#3A is pin-compatible with all other RX113 Group MCUs offered in the PLQP0100KB-A (100-pin LFQFP) package-including R5F51138AGFP#3A, R5F51137AGFP#3A, and R5F51135AGFP#3A. Pin functions, power domains, and peripheral mappings are identical; only flash/RAM capacities and temperature grades differ-enabling scalable design reuse across product tiers.
