Product details
Overview
R5F51306BDFP#30 from Renesas is a 32-bit RX CPU-based microcontroller with 256 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), supporting IEC60730-compliant safety functions and capacitive touch sensing for industrial control panels and appliance HMI interfaces.
For engineers reviewing the R5F51306BDFP#30 datasheet, R5F51306BDFP#30 pinout, R5F51306BDFP#30 application, or R5F51306BDFP#30 equivalent, key selection criteria include its 100-pin LFQFP package, 12-bit A/D converter with 17 channels and 1.4 µs conversion time, dual 8-bit D/A outputs, RTC with calendar mode, and ELC-driven low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51306BDFP#30 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for real-time frequency accuracy monitoring.
Peripheral coordination is managed via Event Link Controller (ELC), allowing direct event-triggered operation of MTU2 timers, A/D conversion, and REMC units while the CPU remains in deep sleep or software standby mode - with recovery time as low as 4.8 µs and standby current of 0.37 µA.

FAQ
What is the maximum operating frequency and associated performance of the R5F51306BDFP#30?
The R5F51306BDFP#30 operates at a maximum frequency of 32 MHz, delivering 50 DMIPS of processing performance. This speed is achievable when supplied with ≥2.7 V; at lower voltages (e.g., 1.8–2.4 V), the max frequency is reduced to 8 MHz. The RXv1 core's single-cycle multiply and 5-stage pipeline ensure deterministic real-time response for control loops and communication stacks in the R5F51306BDFP#30.
Does the R5F51306BDFP#30 support hardware-accelerated capacitive touch sensing?
Yes, the R5F51306BDFP#30 integrates a dedicated Capacitive Touch Sensing Unit (CTSUa) supporting up to 36 self-capacitance channels or matrix configurations with up to 324 keys. It includes built-in noise cancellation, automatic drift compensation, and hardware correlation processing - eliminating the need for external touch controller ICs and reducing BOM cost in the R5F51306BDFP#30-based designs.
What low-power modes are available on the R5F51306BDFP#30, and what is the lowest current consumption?
The R5F51306BDFP#30 offers three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, it consumes just 0.37 µA while maintaining RTC and LPT operation. Wake-up occurs in 4.8 µs via external interrupt or LPT match, making the R5F51306BDFP#30 suitable for battery-powered applications requiring infrequent sensor sampling and long operational life.
How many A/D converter channels does the R5F51306BDFP#30 have, and what is the minimum conversion time?
The R5F51306BDFP#30 includes a 12-bit A/D converter (S12ADE) with 17 input channels. At 32 MHz ADCLK, the minimum conversion time is 1.4 µs per channel. Sampling time is configurable per channel, and the module supports self-diagnostic, analog input disconnection detection, and double-trigger mode for motor control - all implemented in hardware within the R5F51306BDFP#30.
Is the R5F51306BDFP#30 pin-compatible with other members of the RX130 Group?
Yes, the R5F51306BDFP#30 in the 100-pin LFQFP package (PLQP0100KB-B) shares identical pinout with all other RX130 Group devices in that package variant - including R5F51308ADFP#30, R5F51307ADFP#30, and R5F51305BDFP#30. This enables hardware scalability: firmware can be reused across memory variants, and PCB layouts remain unchanged when upgrading flash/SRAM capacity in the R5F51306BDFP#30 family.
