Product details
Overview
R5F101LHAFB#30 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 128 KB flash, 12 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 16-bit timers (12 channels), 10-bit ADC (26 channels), RTC, UART, I²C, CSI, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F101LHAFB#30 datasheet, R5F101LHAFB#30 pinout, R5F101LHAFB#30 application, or R5F101LHAFB#30 equivalent, key selection criteria include its 64-pin LFQFP package, absence of on-chip data flash, industrial-grade temperature support, and suitability for battery-powered sensor nodes, motor control interfaces, and embedded HMI subsystems requiring deterministic real-time response and low active/idle current.
Technical Context
The R5F101LHAFB#30 implements the RL78 CPU core with 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 and banked general-purpose registers (8×8-bit × 4 banks).
Power management includes hardware HALT/STOP/SNOOZE modes, on-chip POR and 14-level LVD, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. The peripheral set features background operation for flash self-programming and BGO-capable data flash access - though R5F101LHAFB#30 omits data flash entirely per part numbering convention.

FAQ
What is the flash memory configuration of the R5F101LHAFB#30?
The R5F101LHAFB#30 contains 128 KB of on-chip code flash memory organized in 1 KB blocks, with no data flash memory - consistent with the "101" part number prefix indicating data flash omission. It supports boot swap functionality and flash shield window protection to prevent unauthorized access or modification of firmware.
Does the R5F101LHAFB#30 support hardware debugging?
Yes, the R5F101LHAFB#30 includes an on-chip debug function accessible via single-wire debug (SWD) interface.

What are the low-power consumption specifications for the R5F101LHAFB#30?
The R5F101LHAFB#30 achieves 66 μA/MHz active current and 0.57 μA in STOP mode with only RTC and LVD enabled. HALT and SNOOZE modes provide intermediate power states, allowing peripherals like UART or timers to remain active while the CPU sleeps - essential for extending battery life in intermittent-sensing applications.
Which communication interfaces are integrated into the R5F101LHAFB#30?
The R5F101LHAFB#30 integrates up to 10 I²C/Simplified I²C channels, 4 UART/LIN channels, and 8 CSI (SPI-compatible) channels. All interfaces support independent operation during SNOOZE mode, enabling continuous sensor data streaming or host communication while the CPU remains in low-power state - reducing system-level power budget.
Is the R5F101LHAFB#30 qualified for industrial temperature operation?
Yes, the R5F101LHAFB#30 is rated for operation from -40°C to +85°C (industrial grade "D" suffix), with full electrical specifications guaranteed across this range.
