Product details
Overview
R5F51136ADFP#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, and integrated USB 2.0 full-speed host/function/OTG. It supports capacitive touch sensing (12 channels), LCD controller (40×4 segment), 12-bit A/D (17 ch), 12-bit D/A (2 ch), RTC, and operates from 1.8–3.6 V in –40 to +85°C industrial environments - used in smart human-interface embedded systems with integrated display and touch.
For engineers reviewing the R5F51136ADFP#3A datasheet, R5F51136ADFP#3A pinout, R5F51136ADFP#3A application, or R5F51136ADFP#3A equivalent, this page delivers verified technical context, package mapping to PLQP0100KB-A (100-pin LFQFP), validated peripheral integration (USB, CTSU, LCDC), real-world use-value metrics (1.0 µs A/D conversion, 4.8 µs wake-up from software standby), and confirmed alternative options for migration or sourcing continuity.
Technical Context
The R5F51136ADFP#3A implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), with independent ICLK/PCLK/FCLK domains enabling precise power-performance trade-offs.
Peripheral coordination is managed via Event Link Controller (ELC), allowing direct module-to-module triggering without CPU intervention - e.g., MTU2 timer events can initiate A/D conversions or LCD refresh cycles while the CPU remains in deep sleep. The Data Transfer Controller (DTC) supports chain transfers across four modes, activated by any of 120 interrupt sources, reducing firmware overhead in sensor-data acquisition and audio streaming applications.

FAQ
What is the maximum operating frequency and core architecture of the R5F51136ADFP#3A?
The R5F51136ADFP#3A features a 32-bit RX CPU core with CISC Harvard architecture and five-stage pipeline, operating at up to 32 MHz (50 DMIPS). It supports variable-length instructions, 64-bit accumulator for single-cycle 32×32 multiply-accumulate, and ultra-compact code density - all confirmed in Renesas datasheet R01DS0216EJ0120. This performance enables real-time HMI and sensor processing without external co-processors.
Does the R5F51136ADFP#3A support USB device, host, and OTG functionality?
Yes, the R5F51136ADFP#3A integrates a USB 2.0 full-speed host/function/OTG module compliant with USB 2.0 specification, supporting 12 Mbps (full-speed) and 1.5 Mbps (low-speed) transfer rates. It includes isochronous transfer, Battery Charger (BC) detection per USB BC 1.2, and on-chip transceiver - eliminating need for external PHY. All USB functionality is fully implemented in the R5F51136ADFP#3A silicon per datasheet Section 1.1.
How many capacitive touch channels does the R5F51136ADFP#3A support, and what package is required?
The R5F51136ADFP#3A supports 12 capacitive touch sensing (CTSU) channels, but only when packaged in the 100-pin variant - specifically PLQP0100KB-A (LFQFP) or PTLG0100JA-A (TFLGA). The 64-pin version omits CTSU entirely. Pin TS0–TS11 are dedicated CTSU inputs; TSCAP provides secondary drive voltage. This capability is documented in Table 1.2 and Section 1.4 of the R5F51136ADFP#3A datasheet.
What are the key low-power features of the R5F51136ADFP#3A, and what is its standby current?
The R5F51136ADFP#3A offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 µA while retaining SRAM and register contents, with 4.8 µs wake-up time via RTC or external interrupt. Its high-speed operating mode consumes 0.11 mA/MHz. These values are measured and specified in the Electrical Characteristics section of the official R5F51136ADFP#3A datasheet (R01DS0216EJ0120).
Is the R5F51136ADFP#3A pin-compatible with other RX113 Group MCUs in the same package?
Yes, all RX113 Group MCUs in the PLQP0100KB-A (100-pin LFQFP) package - including R5F51135ADFP#3A, R5F51136ADFP#3A, R5F51137ADFP#3A, and R5F51138ADFP#3A - share identical pinouts and electrical characteristics. Differences lie only in flash/RAM capacity and enabled peripherals (e.g., CTSU present in R5F51136ADFP#3A and above). This allows scalable design reuse across product tiers using the same R5F51136ADFP#3A PCB layout.
