Product details
Overview
R5F51138ADLJ#2A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D converter, and integrated capacitive touch sensing unit (CTSU) for 12 detection pins - deployed in smart home control panels requiring low-power, human-interface-rich embedded operation.
For engineers reviewing the R5F51138ADLJ#2A datasheet, R5F51138ADLJ#2A pinout, R5F51138ADLJ#2A application, or R5F51138ADLJ#2A equivalent, key selection criteria include TFLGA-100 package compatibility, −40°C to +85°C temperature grade, USB OTG + CTSU + LCD driver integration, and 32 MHz real-time deterministic execution with hardware-accelerated math and event-driven peripheral linking via ELC.
Technical Context
The R5F51138ADLJ#2A implements a CISC Harvard architecture with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes independent PLL, USB-dedicated PLL, IWDT-dedicated 15 kHz oscillator, and CAC for IEC 60730 compliance.
Peripheral coordination is managed by the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for low-latency motor control (via MTU2-triggered A/D conversion) and ultra-low-power wake-up (RTC/LPT-initiated exit from software standby in 4.8 µs).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51138ADFP#3A | Same core/peripherals, but LFQFP-100 (14×14 mm, 0.5 mm pitch); no CTSU support per Table 1.2 | Preferred where PCB rework tolerance exists and touch interface is not required; larger footprint eases hand-soldering | Select when CTSU is unnecessary and thermal/mechanical robustness of QFP is prioritized over miniaturization |
| R5F51138AGLJ#2A | Identical TFLGA-100 package and feature set, but rated for −40°C to +105°C industrial temperature range | Required for under-hood automotive or high-ambient industrial enclosures where extended thermal margin is mandatory | Choose for high-temperature environments; otherwise R5F51138ADLJ#2A suffices for commercial-grade applications |
Compared with R5F51138ADLJ#2A, R5F51138ADFP#3A trades CTSU and compact TFLGA for QFP manufacturability and thermal mass, while R5F51138AGLJ#2A retains identical functionality with extended temperature qualification - making the original optimal for space-constrained, touch-enabled commercial designs within 85°C ambient limits.
