Product details
Overview
R5F101PJDFA#V0 from Renesas is a 100-pin LQFP-0.65mm, 16 KB flash, no data flash, industrial-grade RL78/G13 16-bit MCU operating from 1.6–5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), used in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101PJDFA#V0 datasheet, R5F101PJDFA#V0 pinout, R5F101PJDFA#V0 application, or R5F101PJDFA#V0 equivalent, key selection criteria include its 100-pin LQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature rating, and support for UART/LIN, I²C, and 10-bit ADC across 26 channels.
Technical Context
The R5F101PJDFA#V0 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 subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 2–4 UART/LIN interfaces, 3–10 I²C channels, and 2–8 CSI (SPI-compatible) interfaces - all configurable without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PJDFA#V0 | Same 100-pin LQFP package and peripherals, but includes 4 KB data flash - enables parameter storage without external EEPROM | Better suited for applications requiring field-updatable calibration tables or event logs | Select when non-volatile parameter storage is required; adds 0.25 KB flash overhead per write cycle |
| R5F101PJDFB#V0 | Identical flash/RAM/peripherals, but in 100-pin LFQFP (0.5 mm pitch) - smaller footprint, tighter layout constraints | Preferred for space-constrained PCBs where 0.65 mm pitch LQFP is not feasible | Choose only if assembly process supports 0.5 mm pitch; requires PCB redesign and stencil adjustment |
Compared with R5F101PJDFA#V0, the R5F100PJDFA#V0 adds data flash for robust configuration storage, while R5F101PJDFB#V0 trades pitch compatibility for board area reduction - neither offers pin-to-pin replacement without hardware revision.

FAQ
What is the maximum operating frequency of the R5F101PJDFA#V0?
The R5F101PJDFA#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock switching down to 32.768 kHz for ultra-low-power RTC operation - all verified in the R01DS0131EJ0380 datasheet.
Does the R5F101PJDFA#V0 include on-chip data flash memory?
No, the R5F101PJDFA#V0 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates data flash is omitted - unlike "100" variants (e.g., R5F100PJDFA#V0) which integrate 4 KB. This affects firmware update strategies and requires external non-volatile storage for configuration data.
What package type and pin count does the R5F101PJDFA#V0 use?
The R5F101PJDFA#V0 uses a 100-pin LQFP package with 0.65 mm pitch (RENESAS code PLQP0100JC-A), as confirmed in Table 1-1 of the R01DS0131EJ0380 datasheet. The "#V0" suffix denotes tray packaging, and "FA" in the part number specifies the LQFP-0.65mm variant - distinct from LFQFP ("FB") or QFN packages.
What is the operating temperature range for the R5F101PJDFA#V0?
The R5F101PJDFA#V0 is rated for industrial operation from -40°C to +85°C, indicated by the "D" grade in its part number structure. This is validated across all electrical specifications in the datasheet and qualifies it for deployment in factory automation, building controls, and outdoor metering where ambient extremes are expected.
Which serial communication interfaces are supported by the R5F101PJDFA#V0?
The R5F101PJDFA#V0 supports up to 4 UART/LIN channels, 10 I²C channels, and 8 CSI (SPI-compatible) channels - all implemented in hardware without external transceivers. These interfaces share pins flexibly (e.g., P10/P11 multiplex SCK/SI/RxD/SDA), enabling compact multi-protocol designs per the RL78/G13 peripheral mapping table.
