Product details
Overview
R5F101PLDFA#30 from Renesas is a 32-bit RL78/G13 microcontroller with 128 KB flash memory, 12 KB RAM, and no data flash, housed in a 100-pin LQFP (14 × 20 mm, 0.65-mm pitch) package. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA RTC+LVD), and integrates 26-channel 10-bit ADC, real-time clock, UART/I²C/CSI interfaces, and 16-bit timers - deployed in industrial motor control and sensor-based embedded systems.
For engineers reviewing the R5F101PLDFA#30 datasheet, R5F101PLDFA#30 pinout, R5F101PLDFA#30 application, or R5F101PLDFA#30 equivalent, key selection criteria include its 100-pin LQFP-0.65mm footprint, absence of on-chip data flash, industrial-grade -40°C to +85°C operation (D-grade), and support for background data flash programming via external library.
Technical Context
The R5F101PLDFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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 supporting security-based erase prohibition.
Power management includes on-chip POR and 14-level LVD with selectable interrupt/reset behavior; peripheral integration features 2–4 channel DMA, 16×16→32-bit multiplier, 32÷32-bit divider, and BGO-capable serial interfaces - all optimized for deterministic real-time response in resource-constrained industrial nodes.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101PLDFA#30?
The R5F101PLDFA#30 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This frequency is achievable across the full industrial temperature range (-40°C to +85°C) and 1.6 V to 5.5 V supply, with ±1.0% oscillator accuracy. The RL78 core's 3-stage pipeline ensures deterministic timing for real-time control loops in the R5F101PLDFA#30.
Does the R5F101PLDFA#30 include on-chip data flash memory?
No, the R5F101PLDFA#30 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates data flash omission, distinguishing it from "100"-series variants like R5F100PLDFA#30 which integrate 8 KB data flash. The R5F101PLDFA#30 relies on external nonvolatile storage or code flash emulation for parameter retention.
What industrial temperature grade does the R5F101PLDFA#30 support?
Based on its ordering code suffix "D", the R5F101PLDFA#30 is rated for industrial operation from -40°C to +85°C. This grade meets extended environmental requirements for factory automation, energy infrastructure, and building control systems - verified per Renesas' qualification standards and reflected in the device's guaranteed electrical specifications across that range.
Which communication interfaces are available on the R5F101PLDFA#30?
The R5F101PLDFA#30 integrates multiple serial interfaces: up to 10 channels of I²C/Simplified I²C, 2–4 channels of UART (with LIN-bus support), and 2–8 channels of CSI (Renesas' SPI-compatible interface). All are accessible via dedicated pins in its 100-pin LQFP package, enabling concurrent connection to sensors, displays, wireless modules, and host processors without multiplexing conflicts in the R5F101PLDFA#30.
Can the R5F101PLDFA#30 operate from a single 1.8 V supply?
Yes, the R5F101PLDFA#30 supports operation from 1.6 V to 5.5 V, making 1.8 V fully compliant. At this voltage, the maximum operating frequency is reduced per the datasheet's voltage-frequency curve (typically ≤16 MHz), but all peripherals - including 10-bit ADC, RTC, and serial interfaces - remain functional. This enables direct integration with 1.8 V logic domains in the R5F101PLDFA#30 without level-shifting circuitry.
