Product details
Overview
R5F101LDAFB#X0 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 12 KB RAM, and no data flash memory. It operates from 1.6–5.5 V, achieves 41 DMIPS at 32 MHz, and delivers ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), targeting battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101LDAFB#X0 datasheet, R5F101LDAFB#X0 pinout, R5F101LDAFB#X0 application, or R5F101LDAFB#X0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature rating (D-grade), and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI interfaces.
Technical Context
The R5F101LDAFB#X0 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 128 KB code flash organized in 1-KB blocks and 12 KB on-chip RAM.
Power management includes HALT, STOP, and SNOOZE modes; a programmable on-chip voltage detector (LVD) with 14 selectable levels; and a dedicated low-speed on-chip oscillator for watchdog timer operation. Peripheral integration covers up to 26-channel 10-bit ADC, real-time clock with calendar/alarm, and 3–10 configurable I²C/Simplified I²C channels.

FAQ
What is the flash memory configuration of the R5F101LDAFB#X0?
The R5F101LDAFB#X0 integrates 128 KB of code flash memory organized in 1-KB blocks, with security features including block erase prohibition and flash shield window. It does not include on-chip data flash memory - unlike R5F101LDFAFB#X0, which adds 8 KB of data flash. This makes R5F101LDAFB#X0 ideal for applications storing configuration externally or using code flash for limited parameter storage.
Does the R5F101LDAFB#X0 support hardware debugging?
Yes, the R5F101LDAFB#X0 includes full on-chip debug functionality compatible with Renesas E2 emulator and CS+ IDE. Debug signals are accessible via dedicated pins (e.g., TOOLRxD on P11) and support breakpoints, watchpoints, and real-time variable monitoring without halting peripheral operation - essential for validating timing-critical industrial firmware.
What is the maximum ADC resolution and channel count supported by the R5F101LDAFB#X0?
The R5F101LDAFB#X0 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and temperature sensor (usable only in HS mode), enabling accurate ratiometric measurements and thermal compensation without external components - critical for sensor conditioning in industrial environments.
Can the R5F101LDAFB#X0 operate from a 1.8 V supply?
Yes, the R5F101LDAFB#X0 supports a wide operating voltage range of 1.6 V to 5.5 V, fully functional at 1.8 V. At this voltage, it maintains full peripheral operation including ADC, timers, and serial interfaces, and achieves ultra-low active current (66 μA/MHz typical), making it suitable for single-cell Li-ion or dual-cell alkaline battery systems.
Is the R5F101LDAFB#X0 pin-compatible with other RL78/G13 64-pin variants?
Yes, all RL78/G13 64-pin LFQFP variants - including R5F101LDAFB#X0, R5F101LDFAFB#X0, and R5F101LCAFB#X0 - share identical pinouts and package dimensions (PLQP0064KF-A). This allows direct substitution within the same footprint for memory-scaling or feature-adjusted designs without PCB revision.
