Product details
Overview
R5F101LLDFB#30 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and industrial-grade -40°C to +85°C operation. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, real-time clock with calendar, and ultra-low-power HALT/STOP/SNOOZE modes for battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F101LLDFB#30 datasheet, R5F101LLDFB#30 pinout, R5F101LLDFB#30 application, or R5F101LLDFB#30 equivalent, key selection criteria include its 64-pin LFQFP package, absence of data flash memory, 128 KB code flash capacity, 12 KB RAM allocation, and support for LIN-bus UART, CSI, and I²C serial interfaces in resource-constrained embedded designs.
Technical Context
The R5F101LLDFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It supports background operation during data flash rewriting - though this part lacks data flash - and includes hardware multiplier/divider and MAC units for signal processing tasks.
Its peripheral set includes up to 16 channels of 16-bit timer, 1 channel of 12-bit interval timer, 1 RTC with alarm/calendar, 1 watchdog timer, and DMA controller with 4 channels. The device operates across 1.6–5.5 V supply and features on-chip LVD with 14 selectable voltage detection levels for robust system monitoring.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LLAFB#30 | Same 64-pin LFQFP package and 128 KB flash, but consumer-grade (-40 to +85°C) A-grade qualification | Lacks industrial temperature certification; unsuitable for factory-floor deployments requiring extended thermal margin | Select when cost sensitivity outweighs ambient temperature requirements and no industrial qualification is mandated |
| R5F100LLDFB#30 | Identical package and temperature grade, but includes 8 KB data flash memory and boot swap capability | Enables field-upgradable firmware with dual-bank safe update; required for OTA-capable devices | Choose when non-volatile parameter storage or secure firmware updates are mandatory design requirements |
Compared with R5F101LLDFB#30, R5F101LLAFB#30 trades industrial qualification for lower cost, while R5F100LLDFB#30 adds data flash at the expense of higher BOM cost and slightly larger die size - making R5F101LLDFB#30 optimal for fixed-function, cost-sensitive industrial controllers where field updates are unnecessary.

FAQ
What is the flash memory configuration of the R5F101LLDFB#30?
The R5F101LLDFB#30 contains 128 KB of code flash memory and no data flash memory. This aligns with the "101" series designation in Renesas' RL78/G13 naming convention, which explicitly indicates absence of integrated data flash. The device supports self-programming of code flash with boot swap and flash shield window functions for secure firmware updates.
Does the R5F101LLDFB#30 support LIN bus communication?
Yes, the R5F101LLDFB#30 supports LIN bus communication via its UART peripherals. According to the RL78/G13 datasheet, UART channels can be configured for LIN-bus protocol operation, including automatic sync-break detection and checksum generation. This capability is confirmed for all R5F101x variants, including R5F101LLDFB#30, and requires no external transceiver for basic node functionality.
What is the operating temperature range for the R5F101LLDFB#30?
The R5F101LLDFB#30 is rated for industrial operation from -40°C to +85°C, indicated by the "D" suffix in its product family classification. This temperature grade is validated per Renesas' industrial qualification standards and ensures reliable operation in factory automation, building control, and outdoor instrumentation environments without derating.
Which package type does the R5F101LLDFB#30 use?
The R5F101LLDFB#30 uses a 64-pin LFQFP package with 0.50-mm pitch and 10 × 10 mm body size, identified by the "FB" suffix in the part number. This fine-pitch quad flat package offers high I/O density and compatibility with standard surface-mount assembly processes, and is distinct from the LQFP (0.65-mm pitch) and HWQFN variants in the same family.
Can the R5F101LLDFB#30 operate without an external crystal?
Yes, the R5F101LLDFB#30 can operate fully without an external crystal. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 32 MHz with ±1.0% tolerance across 1.8–5.5 V and -20 to +85°C - sufficient for UART, LIN, and I²C timing. External crystals are optional and used only when tighter frequency stability (e.g., <±100 ppm) is required for specific protocols.
