Product details
Overview
R5F524UEADFP#50 from Renesas Electronics is a 30-pin LSSOP-packaged RL78/G12 16-bit microcontroller designed for ultra-low-power industrial embedded control. It integrates 16 KB code flash, 2 KB data flash, 2 KB RAM, 10-bit 8-channel ADC, dual UART (UART0/UART1), and 8-channel 16-bit TAU timer - operating across –40°C to +85°C with 1.8–5.5 V supply for smart sensors and battery-powered HMI.
For engineers reviewing the R5F524UEADFP#50 datasheet, R5F524UEADFP#50 pinout, R5F524UEADFP#50 application, or R5F524UEADFP#50 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +85°C), on-chip 2 KB data flash with background operation (BGO), DMA support, CRC hardware accelerator, and 30-pin LSSOP package with 26 I/Os including 9 N-ch open-drain pins.
Technical Context
The R5F524UEADFP#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports dual-clock domains: high-speed on-chip oscillator (1–24 MHz, ±1.0% accuracy at –20°C to +85°C) and low-speed 15 kHz on-chip oscillator, enabling HALT/STOP/SNOOZE power modes down to 63 μA/MHz.
Its peripheral set includes SAU0 (4-channel serial array unit supporting UART/CSI/I²C), TAU0 (8-channel 16-bit timer with PWM capability), window watchdog timer, 12-bit interval timer, and on-chip voltage detector with 12-level selectable reset/interrupt thresholds - all configured via dedicated SFRs and PIOR register for flexible I/O remapping.

FAQ
What is the maximum operating frequency and accuracy of the high-speed on-chip oscillator in R5F524UEADFP#50?
The R5F524UEADFP#50 supports a high-speed on-chip oscillator up to 24 MHz with ±1.0% accuracy over –20°C to +85°C ambient temperature. This specification applies specifically to R5F102-series devices like the R5F524UEADFP#50 and is confirmed in Section 1.3.2(1) of the datasheet. The oscillator is factory-trimmed and requires no external components, simplifying BOM and layout.
Does R5F524UEADFP#50 support background operation (BGO) for data flash writes?
Yes, R5F524UEADFP#50 supports background operation (BGO) for its 2 KB data flash memory, allowing CPU code execution from main flash while simultaneously rewriting data flash sectors. This capability is explicitly documented in Section 1.1 Features and enables seamless firmware parameter updates without halting real-time tasks - a critical feature for industrial controllers requiring zero-downtime configuration changes.
How many UART interfaces does R5F524UEADFP#50 provide, and are they fully independent?
R5F524UEADFP#50 provides two fully independent UART interfaces: UART0 and UART1. As shown in the 30-pin block diagram (Page 13) and confirmed in Section 1.7, both UARTs have dedicated registers, baud rate generators, and FIFOs. UART0 uses P11/P12 pins; UART1 uses P00/P01 - enabling concurrent RS-232 diagnostics and Modbus RTU communication without software arbitration.
What is the purpose of the REGC pin on R5F524UEADFP#50, and how must it be connected?
The REGC pin on R5F524UEADFP#50 connects to the internal voltage regulator's stabilization capacitor. Per Section 1.4.3 and Page 17 Absolute Maximum Ratings, it must be connected to VSS via a 0.47–1 µF ceramic capacitor. Failure to do so risks unstable ADC performance, erratic reset behavior, and potential failure to meet specified –40°C to +85°C operation - this is a mandatory hardware requirement, not optional design guidance.
Is R5F524UEADFP#50 pin-compatible with other RL78/G12 30-pin variants such as R5F524TEADFP#50?
Yes, R5F524UEADFP#50 is fully pin-compatible with R5F524TEADFP#50 and all other RL78/G12 30-pin LSSOP variants (e.g., R5F524AEADFP#50). They share identical pin count, pitch, mechanical outline (PLSP0030JB-B), and I/O function mapping per Figure 1-1 and Table 1-1. Firmware and PCB layouts are interchangeable - only code flash size (16 KB vs. 8 KB) and RAM capacity differ between these variants.
