Product details
Overview
R5F51135ADLJ#2A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 32 KB SRAM, 8 KB data flash, USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D converter, and capacitive touch sensing unit (CTSU) with 12 detection channels - deployed in industrial HMI and portable medical devices requiring integrated analog, timing, and human interface functions.
For engineers reviewing the R5F51135ADLJ#2A datasheet, R5F51135ADLJ#2A pinout, R5F51135ADLJ#2A application, or R5F51135ADLJ#2A equivalent, key selection criteria include its TFLGA-100 package (7 × 7 mm, 0.65 mm pitch), −40 to +85°C temperature grade, 1.8–3.6 V supply range, software standby current of 0.44 µA, and CTSU support - all critical for space-constrained, low-power, touch-enabled embedded systems.
Technical Context
The R5F51135ADLJ#2A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, USB-dedicated PLL, and IWDT-dedicated 15 kHz oscillator - all managed via independent ICLK/PCLK/FCLK domains.
Peripheral coordination is handled by the Event Link Controller (ELC), which routes 44 event signals directly between modules (e.g., MTU → A/D start trigger) without CPU intervention, while the Data Transfer Controller (DTC) supports normal, repeat, and block transfers activated by 120 interrupt vectors - enabling deterministic real-time response during sleep modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51135ADFP#3A | Same core, memory, peripherals; differs only in package (LFQFP-100, 14×14 mm, 0.5 mm pitch) and packing (#3A = Sn-only tray) | Requires larger PCB footprint and different reflow profile; no thermal pad; suitable for through-hole prototyping or legacy board reuse | Select when LFQFP mechanical compatibility or existing socket/tooling is required - not pin-compatible with TFLGA due to pitch and pad layout |
| R5F51136ADLJ#2A | Same TFLGA-100 package and temperature grade, but upgraded to 256 KB flash and 32 KB SRAM (vs. 128 KB/32 KB) | Enables larger firmware images (e.g., BLE stack + GUI), deeper data logging buffers, or dual-bank OTA updates | Choose for future-proofing or when additional flash headroom is needed - identical pinout and software compatibility |
