For engineers reviewing the R5F51135AGFM#3A datasheet, R5F51135AGFM#3A pinout, R5F51135AGFM#3A application, or R5F51135AGFM#3A equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LFQFP), validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional and application-level differences.

Technical Context

The R5F51135AGFM#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 operations. It integrates an Event Link Controller (ELC) enabling direct inter-module triggering without CPU intervention and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 44 event sources.

Its clock system includes a high-speed on-chip oscillator (32 MHz ±1% over –20 to +85°C), sub-clock (32.768 kHz), PLL input range (4–8 MHz), and dedicated oscillators for USB (6/8 MHz), IWDT (15 kHz), and RTC - all managed via independent ICLK/PCLK/FCLK domains synchronized to 32 MHz maximum.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51135AGFM#3A?

The R5F51135AGFM#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS (Dhrystone MIPS) performance. Its RX CPU core features a five-stage pipeline, 64-bit accumulator, and single-cycle 32×32 multiplication. Performance is sustained across the full 1.8–3.6 V supply range, with frequency scaling tied to VCC voltage (e.g., 32 MHz only above 2.7 V).

Does the R5F51135AGFM#3A include capacitive touch sensing capability?

No, the R5F51135AGFM#3A does not include the Capacitive Touch Sensing Unit (CTSU). Per Table 1.2 in the official datasheet, CTSU is supported only in the 100-pin package variants (e.g., R5F51135AGFP#3A). The 64-pin PLQP0064KB-A package used by R5F51135AGFM#3A omits this peripheral entirely.

What USB capabilities does the R5F51135AGFM#3A support?

The R5F51135AGFM#3A integrates a USB 2.0 full-speed host/function/OTG module compliant with USB BC 1.2. It supports 12 Mbps full-speed and 1.5 Mbps low-speed transfers, isochronous mode for time-critical data, and battery charging detection. The on-chip transceiver eliminates need for external PHY components.

What are the memory resources available on the R5F51135AGFM#3A?

The R5F51135AGFM#3A includes 128 KB of on-chip flash memory (zero-wait-state at 32 MHz), 32 KB of SRAM (also zero-wait-state), and 8 KB of data flash rated for 1,000,000 erase/write cycles with background operation (BGO) support. All memory is accessible via the MCU's 4-Gbyte linear address space.

How many analog-to-digital converter channels does the R5F51135AGFM#3A have, and what is its speed?

The R5F51135AGFM#3A features a 12-bit A/D converter with 11 input channels in the 64-pin package (per Table 1.2). Its minimum conversion time is 1.0 µs per channel when the ADCLK runs at 32 MHz. It supports scan modes, double-trigger function for motor control synchronization, and multiple trigger sources including MTU timers and external signals.
