FAQ

What is the maximum operating frequency and core performance of the R5F51113ADFM#1A?

The R5F51113ADFM#1A 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 for single-cycle 32×32 multiply-accumulate, and ultra-compact variable-length instruction encoding - enabling efficient code execution in resource-constrained embedded applications.

Does the R5F51113ADFM#1A support USB On-The-Go (OTG) functionality?

Yes, the R5F5113ADFM#1A includes a fully integrated USB 2.0 host/function/OTG module compliant with USB 2.0 specification. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, and Battery Charging (BC) detection. OTG operation requires external USB ID detection and VBUS sensing circuitry, which is supported via USB0_ID and USB0_VBUS pins.

What are the memory resources available on the R5F51113ADFM#1A?

The R5F51113ADFM#1A integrates 64 KB of on-chip flash memory (executed at full 32 MHz with zero wait states), 10 KB of SRAM (also zero-wait-state), and 8 KB of data flash memory rated for 1,000,000 erase/write cycles. The data flash supports Background Operation (BGO), allowing concurrent program execution and nonvolatile parameter storage updates.

How does the R5F51113ADFM#1A achieve low-power operation in battery-powered systems?

The R5F51113ADFM#1A achieves ultra-low-power operation through three dedicated low-power modes: sleep, deep sleep, and software standby. In software standby mode, it consumes just 0.44 µA while retaining SRAM and register contents, and recovers in 4.8 µs - enabling rapid wake-on-event response. Its 1.8–3.6 V supply range and dynamic operating mode control further optimize energy use across varying workloads.

Is the R5F51113ADFM#1A qualified for industrial temperature range and safety standards?

Yes, the R5F51113ADFM#1A is rated for −40°C to +85°C (D-grade) operation and includes on-chip functions to aid IEC 60730 Class B compliance - including Clock Accuracy Measurement (CAC), Independent Watchdog Timer (IWDT) with dedicated oscillator, RAM test assist, and voltage monitoring circuits. These features reduce development effort for safety-certified industrial and white-goods applications.
