For engineers reviewing the R5F51306BGFL#10 datasheet, R5F51306BGFL#10 pinout, R5F51306BGFL#10 application, or R5F51306BGFL#10 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7×7 mm, 0.5 mm pitch), functional pin roles, real-world use cases, and two validated alternative parts with documented technical and application differences.
Technical Context
The R5F51306BGFL#10 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. It integrates an Event Link Controller (ELC) that enables interrupt-free inter-module triggering and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 47 event sources.
Its clock system includes a high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and dedicated IWDT oscillator (15 kHz), with independent clock domains for ICLK (CPU/system), PCLKB (peripherals), and FCLK (FlashIF). The MCU supports three low-power modes, including software standby with 0.37 µA supply current and 4.8 µs wake-up time.

The R5F51306BGFL#10 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS (Dhrystone MIPS) performance using the 32-bit RXv1 core. Its 5-stage pipeline, single-cycle 32×32-bit multiply, and ultra-compact instruction encoding enable high code density and deterministic real-time execution-critical for responsive industrial control loops within the R5F51306BGFL#10's thermal envelope.
Does the R5F51306BGFL#10 support capacitive touch sensing, and how many keys are available in its package?
Yes, the R5F51306BGFL#10 integrates a Capacitive Touch Sensing Unit (CTSUa) supporting up to 24 keys in mutual capacitance mode. This capability is confirmed for the PLQP0048KB-B 48-pin LFQFP package per Table 1.2 of the datasheet. The R5F51306BGFL#10 uses TS0–TS23 pins for touch electrode connections and includes built-in noise immunity features essential for reliable operation in noisy industrial environments.
What are the memory resources included in the R5F51306BGFL#10?
The R5F51306BGFL#10 includes 256 KB of on-chip flash memory (with no wait states at 32 MHz), 32 KB of SRAM (also zero-wait-state), and 8 KB of data flash rated for 1,000,000 program/erase cycles. The data flash supports Background Operation (BGO), allowing firmware updates or parameter storage without halting CPU execution-enabling seamless field upgrades in deployed R5F51306BGFL#10-based systems.
What low-power modes does the R5F51306BGFL#10 support, and what is its lowest supply current?
The R5F51306BGFL#10 supports three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode-with the low-power timer (LPT) active-the device draws just 0.37 µA typical supply current. Wake-up occurs in 4.8 µs, enabling rapid response to external events while maintaining ultra-low energy consumption-ideal for battery-operated R5F51306BGFL#10 applications such as wireless sensor nodes.
Is the R5F51306BGFL#10 qualified for industrial temperature operation, and what is its rated range?
Yes, the R5F51306BGFL#10 is rated for industrial temperature operation from –40°C to +105°C (G-grade). This specification is explicitly stated in Table 1.3 of the datasheet and applies to all variants ending in "G", including R5F51306BGFL#10. The extended range ensures reliable operation in demanding environments such as factory-floor controllers, outdoor equipment, and enclosed industrial drives where ambient heat buildup occurs.
