Product details
Overview
R5F101LDAFB#30 from Renesas is a 64-pin, LFQFP-0.5mm-pitch, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 12 KB RAM, and no data flash memory. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD-only STOP mode), targeting battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101LDAFB#30 datasheet, R5F101LDAFB#30 pinout, R5F101LDAFB#30 application, or R5F101LDAFB#30 equivalent, key selection criteria include its 64-pin LFQFP package, absence of on-chip data flash, industrial temperature range (−40°C to +85°C), and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI serial interfaces.
Technical Context
The R5F101LDAFB#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space, with dedicated SFR regions for peripheral control and register banks enabling efficient context switching.
Power management includes hardware HALT/STOP/SNOOZE modes, on-chip POR and 14-level LVD with interrupt/reset options, and a high-accuracy ±1.0% on-chip oscillator (32 MHz max). Peripheral integration features DMA (4 channels), 16×16/32÷32 multiplier/divider, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.

FAQ
What is the maximum operating frequency and performance rating of the R5F101LDAFB#30?
The R5F101LDAFB#30 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The measured 41 DMIPS value reflects real-world integer processing throughput under typical compiler optimization and memory access conditions, making it suitable for real-time control tasks in industrial and metering applications.
Does the R5F101LDAFB#30 include on-chip data flash memory?
No, the R5F101LDAFB#30 does not include on-chip data flash memory. Per Renesas part numbering convention, the "1" in the second digit (R5F101LDAFB#30) explicitly indicates data flash is omitted. This distinguishes it from R5F100LDAFB#30 (which includes 8 KB data flash) and reduces flash management complexity for applications that store configuration only in external EEPROM or serial flash.
What package type and pin count does the R5F101LDAFB#30 use?
The R5F101LDAFB#30 uses a 64-pin LFQFP package with 0.5 mm pitch and dimensions of 10 mm × 10 mm (PLQP0064KF-A). The "FB" suffix in the part number confirms the LFQFP-0.5mm variant, and the "L" in position 6 (R5F101LDAFB#30) denotes the 64-pin configuration per Renesas RL78/G13 ordering guide.
What is the operating temperature range certified for the R5F101LDAFB#30?
The R5F101LDAFB#30 is rated for industrial operation from −40°C to +85°C (D grade). This is confirmed by the "D" in the 7th character of the part number (R5F101LDAFB#30), which designates the industrial temperature grade per Renesas RL78/G13 documentation, distinguishing it from consumer-grade "A" (−40°C to +85°C) and extended industrial "G" (−40°C to +105°C) variants.
Which serial communication interfaces are supported by the R5F101LDAFB#30?
The R5F101LDAFB#30 supports CSI (SPI-compatible), UART/LIN, and I²C interfaces - with up to 8 CSI channels, 4 UART/LIN channels, and 10 I²C channels. These interfaces share pins (e.g., P10/P11 for SCK00/SCL00 and SI00/RxD0), allowing flexible allocation based on system requirements without additional external logic.
