Product details
Overview
R5F51111ADFK#5A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 KB on-chip flash, 10 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, RTC, and ELC for event-driven low-power operation - deployed in industrial HMI, sensor nodes, and USB-connected embedded control systems.
For engineers reviewing the R5F51111ADFK#5A datasheet, R5F51111ADFK#5A pinout, R5F51111ADFK#5A application, or R5F51111ADFK#5A equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and validated alternative options aligned with IEC 60730-compliant design requirements.
Technical Context
The R5F51111ADFK#5A 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, while the integrated DTC and ELC enable interrupt-free peripheral coordination during CPU sleep.
It integrates a high-accuracy 32 MHz ±1% on-chip oscillator (−20 to +85°C), programmable LVD with 10 voltage levels, and independent watchdog timer driven by a dedicated 15 kHz oscillator - all supporting functional safety compliance per IEC 60730 Class B requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RX 32-bit CISC Harvard, 32 MHz max, 50 DMIPS - enables deterministic real-time control with minimal code footprint. |
| Memory | 32 KB flash (no wait states @32 MHz), 10 KB SRAM, 8 KB data flash (1M erase/write cycles) - supports field firmware updates and parameter storage without external EEPROM. |
| 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 sensing and actuation in motor or power control. |
| USB Interface | USB 2.0 full-speed host/function/OTG (12 Mbps), BC 1.2 battery charging support - enables direct USB connectivity for configuration, data logging, or peripheral attachment. |
| Low-Power Modes | Software standby mode (0.44 µA), 4.8 µs wake-up time - ideal for battery-powered endpoints requiring rapid responsiveness after extended sleep. |
| Operating Range | −40°C to +85°C, 1.8–3.6 V supply - qualified for industrial ambient and wide-input power rail applications. |
| Package | PLQP0064GA-A, 64-pin LQFP, 14 × 14 mm, 0.8 mm pitch - compatible with standard surface-mount assembly and thermal management in compact PCB layouts. |
Pinout & Package
Package: PLQP0064GA-A - 64-pin LQFP, 14 × 14 mm body, 0.8 mm pitch, exposed pad (non-electrical), RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual 3.3 V supply domains (core/analog/USB); decoupling required per datasheet layout guidelines. |
