Product details
Overview
R5F101PLDFB#V0 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash memory, 12 KB RAM, and no data flash. 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 mode), targeting battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101PLDFB#V0 datasheet, R5F101PLDFB#V0 pinout, R5F101PLDFB#V0 application, or R5F101PLDFB#V0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D suffix), and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI interfaces.
Technical Context
The R5F101PLDFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with flash organized in 1 KB blocks and security features including block erase prohibition.
Peripherals include up to 16 channels of 16-bit timer, one real-time clock with calendar and alarm, watchdog timer with dedicated low-speed oscillator, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and serial interfaces: CSI (SPI-compatible), UART/LIN (up to 4 channels), and I²C/Simplified I²C (up to 10 channels).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101PLAFB#V0 | Same 100-pin LFQFP package and 128 KB flash, but uses LQFP-0.65mm pitch (FA suffix) instead of LFQFP-0.5mm (FB suffix) | Requires PCB layout change due to different pitch and footprint; otherwise identical peripheral set and memory configuration | Select when legacy board designs use 0.65-mm pitch LQFP or when assembly process favors larger pitch tolerance |
| R5F100PLDFB#V0 | Same 100-pin LFQFP-0.5mm package and pinout, but includes 8 KB data flash memory and supports background data flash rewriting | Enables field-upgradable parameter storage and wear-leveling; adds ~1 KB RAM overhead for flash library usage | Select when non-volatile parameter storage, OTA updates, or data logging are required - otherwise R5F101PLDFB#V0 offers lower cost and simpler firmware |
Compared with R5F101PLDFB#V0, R5F101PLAFB#V0 requires PCB redesign for pitch compatibility, while R5F100PLDFB#V0 adds data flash functionality at higher cost and firmware complexity - making R5F101PLDFB#V0 optimal for fixed-parameter, cost-sensitive industrial control where flash reprogramming occurs only during manufacturing.

The R5F101PLDFB#V0 is rated for industrial operation from -40°C to +85°C (D-grade), validated across its full voltage range (1.6 V to 5.5 V) and functional specifications - making it suitable for factory automation, outdoor equipment, and uncontrolled-environment deployments where thermal stability is critical.
Does R5F101PLDFB#V0 include on-chip data flash memory?
No, R5F101PLDFB#V0 does not include data flash memory. The "101" in the part number explicitly denotes absence of data flash, distinguishing it from "100" variants like R5F100PLDFB#V0 which integrate 8 KB data flash with background operation and 1 million rewrite cycles.
What debug interface does R5F101PLDFB#V0 support?
R5F101PLDFB#V0 supports on-chip debug via the single-wire debug interface (SWD) using the dedicated TOOLx pins (e.g., TOOLRxD/TOOLTxD), enabling full JTAG-equivalent functionality including breakpoints, watchpoints, and real-time memory inspection without requiring additional debug headers or trace ports.
Can R5F101PLDFB#V0 operate without an external crystal?
Yes, R5F101PLDFB#V0 integrates a high-accuracy on-chip oscillator (±1.0% from -20°C to +85°C) with selectable frequencies from 1 MHz to 32 MHz, eliminating the need for external crystals in most applications - though optional external resonators can be used for higher precision timing requirements.
How many serial communication interfaces are available on R5F101PLDFB#V0?
R5F101PLDFB#V0 provides up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - with physical pin allocation depending on port configuration, enabling concurrent sensor buses, diagnostics links, and display interfaces in compact industrial designs.
