Product details
Overview
R5F51103ADLM#U0 from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 Kbytes of on-chip flash, 10 Kbytes of SRAM, a 12-bit A/D converter with 7 input channels, RTC, and I²C/SCI/RSPI interfaces - deployed in compact embedded control for industrial sensors and low-power IoT endpoints.
For engineers reviewing the R5F51103ADLM#U0 datasheet, R5F51103ADLM#U0 pinout, R5F51103ADLM#U0 application, or R5F51103ADLM#U0 equivalent, key selection criteria include its 36-pin WFLGA (PWLG0036KA-A) package, −40 to +85°C temperature grade, software standby current of 0.35 μA, 4.8 μs wake-up time, and support for IEC 60730-compliant safety functions.
Technical Context
The R5F51103ADLM#U0 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its RX CPU includes a 64-bit accumulator for 32×32-bit operations and integrated multiplication/division hardware.
It integrates dedicated clock domains (ICLK/PCLK/FCLK), on-chip oscillators (32 MHz ±1%, 4 MHz, 15 kHz, 32.768 kHz), and a Clock Accuracy Measurement Circuit (CAC) for functional safety compliance. The MCU supports three low-power modes - sleep, deep sleep, and software standby - with recovery in 4.8 μs from the deepest mode.

FAQ
What is the maximum operating frequency and associated performance of the R5F51103ADLM#U0?
The R5F51103ADLM#U0 operates at a maximum frequency of 32 MHz, delivering 50 DMIPS of processing performance. This speed is achievable only when the supply voltage is ≥2.7 V; at lower voltages (1.8–2.4 V), the max frequency reduces to 8 MHz. The RX CPU's five-stage pipeline and single-cycle instruction execution enable deterministic real-time response critical for control loops and sensor fusion tasks in the R5F51103ADLM#U0.
Which package type and dimensions does the R5F51103ADLM#U0 use?
The R5F51103ADLM#U0 uses the PWLG0036KA-A package: a 36-pin Wafer-Level Glass Array measuring 4 × 4 mm with 0.5 mm pitch and an exposed die pad. This ultra-compact WFLGA package minimizes PCB area while maintaining thermal performance - the die pad must be soldered to VSS for optimal electrical stability and heat dissipation in the R5F51103ADLM#U0 design.
How many A/D input channels does the R5F51103ADLM#U0 support, and what are their key timing characteristics?
The R5F51103ADLM#U0 supports 7 A/D input channels (AN000–AN004, AN006, AN008–AN010). Its 12-bit S12AD unit achieves a minimum conversion time of 1.0 μs when the ADCLK runs at 32 MHz. Conversion can be triggered by software, MTU timer output, or the external ADTRG0# pin - enabling precise synchronization with motor commutation or power-line zero-crossing events in R5F51103ADLM#U0-based systems.
Does the R5F51103ADLM#U0 include built-in safety features for IEC 60730 compliance?
Yes, the R5F51103ADLM#U0 integrates multiple hardware features supporting IEC 60730 Class B compliance: a Clock Accuracy Measurement Circuit (CAC), Independent Watchdog Timer (IWDT) with dedicated 15 kHz oscillator, RAM test assist functions, and dual voltage detection circuits (LVDAa). These eliminate the need for external safety monitors and simplify certification efforts for the R5F51103ADLM#U0 in white goods and industrial controls.
What communication interfaces are available on the R5F51103ADLM#U0, and how many channels does each support?
The R5F51103ADLM#U0 provides SCI (2 channels: SCI1 and SCI5), RIIC (1 channel), and RSPI (1 channel). SCI supports asynchronous, clock-synchronous, and simple I²C/SPI modes; RIIC operates up to 400 kbps in master/slave; RSPI supports up to 16 Mbps with 8–32 bit frame lengths. All interfaces are accessible via multi-function pins routed through the MPC - no dedicated pins are hardwired, maximizing flexibility in the R5F51103ADLM#U0 layout.
