Product details
Overview
R5F101PLAFA#30 from Renesas is a 100-pin LQFP-0.65mm, 32-bit RL78/G13 microcontroller with 64 KB flash, 4 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, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and SPI interfaces for embedded control in metering and sensor nodes.
For engineers reviewing the R5F101PLAFA#30 datasheet, R5F101PLAFA#30 pinout, R5F101PLAFA#30 application, or R5F101PLAFA#30 equivalent, key selection criteria include its 100-pin LQFP package, absence of on-chip data flash, industrial-grade temperature support, and compatibility with Renesas' RL78 toolchain and E2 studio IDE for rapid firmware development and low-power system validation.
Technical Context
The R5F101PLAFA#30 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). It includes dedicated peripherals for real-time control: one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, and a watchdog timer driven by a dedicated low-speed on-chip oscillator.
Its memory subsystem comprises 64 KB code flash (1 KB block size, self-programmable with boot swap), 4 KB SRAM, and no data flash - distinguishing it from R5F100x variants. Power management includes HALT, STOP, and SNOOZE modes, POR, and an LVD with 14 selectable voltage thresholds for robust brown-out handling in battery-powered applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFA#30 | Includes 4 KB data flash memory; identical pinout and package; same 64 KB code flash and 4 KB RAM | Enables EEPROM-like parameter storage without external memory; suitable where field-updatable calibration or logging is required | Select when non-volatile parameter retention between power cycles is mandatory |
| R5F101PLAFA#50 | Identical electrical and functional specs; differs only in packaging - embossed tape instead of tray | No impact on circuit design or firmware; intended for automated SMT assembly rather than manual or small-batch use | Select for high-volume production requiring tape-and-reel feeding |
Compared with R5F100PLAFA#30, the R5F101PLAFA#30 trades data flash for marginally lower cost and simpler flash management, while R5F101PLAFA#50 offers identical functionality in tape format - both preserve full pin, code, and timing compatibility for drop-in reuse in existing PCB layouts.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101PLAFA#30?
The R5F101PLAFA#30 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs at this frequency, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - all within the same device without external components.
Does the R5F101PLAFA#30 include data flash memory?
No, the R5F101PLAFA#30 does not include data flash memory. The "101" in the part number explicitly indicates no data flash, unlike "100" variants (e.g., R5F100PLAFA#30) which integrate 4 KB of data flash. Code flash remains fully programmable with self-programming and boot swap functions.
What package type and pin count does the R5F101PLAFA#30 use?
The R5F101PLAFA#30 uses a 100-pin LQFP package with 0.65-mm pitch (14 × 20 mm body), identified by the "FA" suffix and "#30" tray packaging code. This matches PLQP0100JC-A mechanical specifications and is compatible with standard LQFP reflow profiles and pick-and-place equipment.
Which temperature grade applies to the R5F101PLAFA#30?
The R5F101PLAFA#30 is rated for industrial temperature operation from -40°C to +85°C, indicated by the "D" in its family designation (RL78/G13-D). It is not rated for extended industrial (-40°C to +105°C) or consumer-grade operation - verify ambient conditions match this range during system thermal design.
Can the R5F101PLAFA#30 operate from a single 1.8 V supply?
Yes, the R5F101PLAFA#30 supports operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, maximum operating frequency is reduced per datasheet limits (typically ≤ 8 MHz), but all peripherals - including ADC, timers, and serial interfaces - remain functional, enabling ultra-low-voltage battery applications.
