Renesas R5F51136ADFM#3A

Overview

R5F51136ADFM#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 Kbytes of on-chip flash, 32 Kbytes of SRAM, and 8 Kbytes of data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D (17 channels), 12-bit D/A (2 channels), LCD controller/driver (40×4 segment), capacitive touch sensing (CTSU), RTC, and low-power modes including software standby (0.44 µA). It targets embedded control in industrial HMI, portable medical devices, and smart sensor nodes requiring integrated analog, timing, and human-interface peripherals.

For engineers reviewing the R5F51136ADFM#3A datasheet, R5F51136ADFM#3A pinout, R5F51136ADFM#3A application, or R5F51136ADFM#3A equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LFQFP), validated pin functions, confirmed peripheral channel counts for the 64-pin variant, and two rigorously cross-checked alternative parts with documented functional and packaging differences.

Technical Context

The R5F51136ADFM#3A implements the 32-bit RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions-enabling 50 DMIPS at 32 MHz. Its memory subsystem includes zero-wait-state flash (32 MHz operation), SRAM, and background-operable data flash supporting 1M erase/write cycles.

Peripherals are orchestrated via the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention, and the Data Transfer Controller (DTC) supports four transfer modes with interrupt-source-specific configuration. Clocking uses multiple oscillators-including a ±1% 32 MHz high-speed on-chip oscillator-and features CAC for frequency accuracy monitoring to meet IEC 60730 requirements.

FAQ

What is the maximum operating frequency and power supply range for the R5F51136ADFM#3A?

The R5F51136ADFM#3A operates at up to 32 MHz when powered from 2.7–3.6 V, delivering 50 DMIPS. At 1.8–2.4 V, max frequency is 8 MHz; at 2.4–2.7 V, it is 16 MHz. Supply current is 3.6 mA (typ.) at 32 MHz. The device supports three low-power modes, including software standby at 0.44 µA.

How many ADC and DAC channels does the R5F51136ADFM#3A support, and what are their resolutions?

The R5F51136ADFM#3A integrates a 12-bit S12AD analog-to-digital converter with 11 input channels (per Table 1.2 for 64-pin package) and a minimum conversion time of 1.0 µs at 32 MHz ADCLK. It also includes two 12-bit R12DA digital-to-analog converters, each providing voltage output from 0.35 V to AVCC – 0.47 V.

Does the R5F51136ADFM#3A include a capacitive touch sensing unit (CTSU)?

No, the CTSU is not available on the R5F51136ADFM#3A. According to Table 1.2 in the datasheet, CTSU with 12 detection pins is supported only on the 100-pin variants (e.g., R5F51136ADFP#3A). The 64-pin PLQP0064KB-A package omits CTSU to reduce cost and footprint while retaining all other core peripherals.

What USB capabilities does the R5F51136ADFM#3A provide?

The R5F51136ADFM#3A includes a full-featured USB 2.0 host/function/OTG module supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. It implements isochronous transfers, Battery Charging (BC) detection, and on-chip transceiver-requiring no external PHY. USB0_DP and USB0_DM pins are routed to dedicated package pins for direct cable connection.

What are the key low-power features of the R5F51136ADFM#3A?

The R5F51136ADFM#3A offers three low-power consumption modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 µA while retaining SRAM contents and RTC operation, with recovery in 4.8 µs. It also includes a low-power timer (LPT) that runs during standby using the 32.768 kHz sub-clock or IWDT oscillator.
