Renesas R5F52107BDFB#10

Overview

R5F52107BDFB#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 384 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels, 1 μs conversion), and real-time clock with deep software standby wake-up capability - deployed in industrial control panels requiring deterministic timing and IEC60730-compliant self-diagnostic functions.

For engineers reviewing the R5F52107BDFB#10 datasheet, R5F52107BDFB#10 pinout, R5F52107BDFB#10 application, or R5F52107BDFB#10 equivalent, this MCU delivers verified low-power operation across −40°C to +85°C, ELC-driven event-triggered peripheral activation without CPU intervention, and hardware-assisted CRC calculation for firmware integrity verification in safety-critical embedded systems.

Technical Context

The R5F52107BDFB#10 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, enabling ultra-compact code density and single-cycle 32×32-bit multiplication. Its on-chip debugging circuit supports FINE interface via E1 emulator, and the CPU core executes instructions at one per system clock cycle at 50 MHz.

It integrates dual timer subsystems: six-channel MTU2 supporting complementary PWM and phase counting, and six-channel TPU (in 144-pin packages) for input capture and synchronized A/D triggers. The ELC directly routes 59 event signals to peripherals, enabling autonomous operation during CPU sleep modes including deep software standby with RTC active.

FAQ

What is the maximum operating frequency and associated performance metric for the R5F52107BDFB#10?

The R5F52107BDFB#10 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS (Dhrystone MIPS) performance. This is achieved through its 32-bit RX CPU core with 5-stage pipeline, variable-length instruction set, and single-cycle 32×32-bit multiplication unit. The R5F52107BDFB#10 sustains this performance with zero wait-state access to both flash and SRAM at full speed.

Does the R5F52107BDFB#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F52107BDFB#10 includes hardware-assisted features required for IEC60730 Class B compliance, including clock accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, A/D converter self-diagnostic and analog input disconnection detection, and RAM test support functions. These are documented in the R01DS0041EJ0150 datasheet and do not require external components to implement.

What package type and pin count does the R5F52107BDFB#10 use?

The R5F52107BDFB#10 uses a 144-pin LQFP package designated PLQP0144KA-A, measuring 20 × 20 mm with 0.5-mm pitch and lead-free (RoHS-compliant) finish. It provides 122 general-purpose I/O pins, four 5-V-tolerant inputs, and full access to all peripherals including external bus interface, RTC, and dual timer units.

Can the R5F52107BDFB#10 operate from a 1.62-V supply, and what are the frequency limitations?

Yes, the R5F52107BDFB#10 supports operation down to 1.62 V, but only at frequencies up to 20 MHz per the datasheet's power supply vs. frequency derating table. At 1.8–2.7 V, it operates up to 32 MHz; at 2.7–5.5 V, it achieves full 50 MHz performance. All voltage ranges support full peripheral functionality including flash programming and A/D conversion.

How many communication interfaces does the R5F52107BDFB#10 integrate, and which are available in the 144-pin package?

The R5F52107BDFB#10 integrates up to 15 communication channels: 13 SCI (SCI0–SCI11 + SCI12), 1 I²C (RIIC), and 1 RSPI. In the 144-pin LQFP package, all 13 SCI channels, the full I²C interface, and RSPI are fully implemented and electrically accessible - confirmed in Table 1.2 of the R01DS0041EJ0150 datasheet.
