Product details
Overview
R5F51137ADLJ#20 from Renesas is a 32-bit RX113 Group microcontroller with 384 KB flash, 64 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), featuring USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D, dual 12-bit D/A, LCD controller/driver (40×4), capacitive touch sensing (12 channels), RTC, and CTSU - deployed in industrial HMI, portable medical devices, and smart sensor nodes.
For engineers reviewing the R5F51137ADLJ#20 datasheet, R5F51137ADLJ#20 pinout, R5F51137ADLJ#20 application, or R5F51137ADLJ#20 equivalent, this page delivers verified package mapping (PTLG0100JA-A, 100-pin TFLGA), confirmed low-power modes (software standby: 0.44 µA), USB OTG support, CTSU noise cancellation, and real-world timing accuracy (32 MHz ±1% on-chip oscillator).
Technical Context
The R5F51137ADLJ#20 integrates a CISC Harvard-architecture RX CPU with five-stage pipeline, 64-bit accumulator for single-cycle 32×32 multiply, and on-chip debugging via FINE interface. Its clock system includes independent PLL, USB-dedicated PLL, IWDT-dedicated 15 kHz oscillator, and CAC for frequency accuracy validation.
Peripheral coordination is managed by the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention, and the Data Transfer Controller (DTC) supports chain transfers across four modes using interrupt sources as activation triggers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51137ADFP#3A | Same core, memory, and peripherals but in 100-pin LFQFP (PLQP0100KB-A, 14×14 mm); no TFLGA footprint | Preferred where board-level rework tolerance or hand-soldering is required | Select when mechanical constraints favor QFP over LGA or thermal management requires exposed pad access |

FAQ
What is the maximum operating frequency and core performance of the R5F51137ADLJ#20?
The R5F51137ADLJ#20 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core features a five-stage pipeline, 64-bit accumulator for single-cycle 32×32 multiplication, and variable-length instruction encoding. This enables deterministic real-time response in motor control and sensor fusion applications where the R5F51137ADLJ#20 is commonly deployed.
Does the R5F51137ADLJ#20 support USB On-The-Go (OTG) functionality?
Yes, the R5F51137ADLJ#20 integrates a USB 2.0 host/function/OTG module compliant with USB 2.0 specification, supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, and Battery Charging (BC) detection. The R5F51137ADLJ#20 uses dedicated USB pins (USB0_DP/DM), VBUS monitoring, and ID pin sensing to enable role switching - essential for portable devices that act as both USB hosts and peripherals.
How many analog input channels does the R5F51137ADLJ#20 include, and what is its A/D conversion speed?
The R5F51137ADLJ#20 includes 17 analog input channels for its 12-bit A/D converter, with a minimum conversion time of 1.0 µs per channel when ADCLK runs at 32 MHz. It supports scan, group scan, and double-trigger modes - the latter duplicates conversion results for motor control fault detection. These capabilities make the R5F51137ADLJ#20 suitable for multi-sensor systems requiring synchronized, high-fidelity analog acquisition.
What low-power modes are available on the R5F51137ADLJ#20, and what is its software standby current?
The R5F51137ADLJ#20 supports three low-power consumption modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 µA while retaining SRAM content and enabling wake-up via RTC alarm, external interrupt, or LPT event. Recovery time is 4.8 µs - critical for battery-powered applications where the R5F51137ADLJ#20 must respond rapidly to intermittent events without sacrificing energy efficiency.
Is the R5F51137ADLJ#20 pin-compatible with other members of the RX113 Group?
The R5F51137ADLJ#20 shares the same PTLG0100JA-A (100-pin TFLGA) package and pinout with other RX113 Group devices in that package variant, including R5F51138ADLJ#2A and R5F51136ADLJ#2A. However, peripheral enablement differs: R5F51137ADLJ#20 provides all 17 A/D channels and full CTSU support, whereas lower-memory variants may disable certain channels or functions. Always verify peripheral mapping in the specific device's datasheet before substituting the R5F51137ADLJ#20.
