Product details
Overview
R5F51115ADFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and hardware event linking - deployed in industrial HMI, sensor node controllers, and USB-connected embedded gateways.
For engineers reviewing the R5F51115ADFM#30 datasheet, R5F51115ADFM#30 pinout, R5F51115ADFM#30 application, or R5F51115ADFM#30 equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and two validated alternative parts for design flexibility and supply continuity.
Technical Context
The R5F51115ADFM#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its 64-bit accumulator supports 32×32-bit multiply-accumulate operations in one cycle, while the DTC and ELC enable zero-CPU-overhead peripheral coordination - critical for deterministic motor control and low-latency sensor fusion.
It integrates a dedicated 32 MHz ±1% on-chip oscillator (−20 to +85°C), independent IWDT with 15 kHz clock, and CAC circuit for IEC 60730 compliance. Clock domains are fully decoupled: ICLK (system), PCLK (peripherals), and FCLK (flash) each support independent scaling up to 32 MHz, ensuring timing integrity across mixed-speed subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RX 32-bit CISC Harvard, 32 MHz max, 50 DMIPS - enables real-time deterministic execution without external cache. |
| Memory | 128 KB flash (no wait states @32 MHz), 16 KB SRAM, 8 KB data flash (1M erase/write cycles) - supports field firmware updates and parameter storage. |
| ADC/DAC | 14-channel 12-bit ADC (1.0 µs min conversion), 2-channel 8-bit DAC (0–VCC output) - suitable for closed-loop analog control with simultaneous sampling. |
| USB Interface | USB 2.0 full-speed (12 Mbps) host/function/OTG with BC (Battery Charger) and isochronous transfer - enables direct USB peripheral attachment and power negotiation. |
| Timers & Control | 6-channel MTU2 (PWM, input capture, phase counting), 2-channel CMT, ELC, and DTC - allows synchronized PWM generation, encoder interfacing, and background DMA transfers. |
| Operating Range | 1.8–3.6 V supply, −40 to +85°C (D-grade), software standby current 0.44 µA with 4.8 µs wake-up - optimized for battery-backed and wide-temperature industrial use. |
Pinout & Package
Package: PLQP0064KB-A - 64-pin LFQFP, 10 × 10 mm body, 0.5 mm pitch, exposed pad (thermal enhancement), RoHS-compliant Sn finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Core power / ground | Dual 3.3 V supply domains: VCC powers digital logic; VSS provides reference return - requires local 100 nF + 4.7 µF decoupling per VCC/VSS pair. |
| USB0_DP / USB0_DM | USB differential data lines | On-chip transceiver with full-speed PHY; requires 27 Ω series resistors and 1.5 kΩ pull-up on DP for device mode - no external PHY needed. |
| AN000–AN015 | Analog input channels | 14 dedicated ADC inputs (AN000–AN004, AN006, AN008–AN015); AVCC0/AVSS0 must be separately filtered for <1 LSB noise performance. |
| DA0 / DA1 | Analog voltage outputs | Two rail-to-rail 8-bit DAC outputs (0–VCC); usable for biasing sensors, programmable references, or simple waveform generation without external DAC IC. |
| MTIOC0A–MTIOC5W | PWM & capture I/O | 16 dedicated timer I/O pins across six MTU2 channels - support complementary PWM with dead-time insertion and quadrature encoder input via phase counting mode. |
| RES# / MD | Reset / mode configuration | Active-low RES# initiates hardware reset; MD pin sets boot mode (fixed at power-on) - must be held stable during operation per Renesas design guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Event Link Controller (ELC) | Direct hardware triggering between 35 event sources and peripherals - eliminates interrupt latency and CPU load for time-critical signal chains (e.g., ADC→DTC→RAM). |
