Product details
Overview
R5F101LDAFA#30 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade (–40°C to +85°C) RL78/G13 16-bit MCU with 64 KB flash, 4 KB data flash, 4 KB RAM, 32 MHz max CPU speed, and integrated 10-bit ADC (26 channels), RTC, UART, I²C, and SPI interfaces - deployed in smart metering firmware and industrial sensor node control.
For engineers reviewing the R5F101LDAFA#30 datasheet, R5F101LDAFA#30 pinout, R5F101LDAFA#30 application, or R5F101LDAFA#30 equivalent, key selection criteria include its no-data-flash configuration, industrial temperature rating, LQFP-64 package with 0.65-mm pitch, ultra-low-power STOP/HALT modes (0.57 μA RTC+LVD), and RL78 core's 41 DMIPS @ 32 MHz performance.
Technical Context
The R5F101LDAFA#30 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 on-chip power-on-reset (POR), 14-level voltage detector (LVD), and background operation (BGO) for data flash rewriting while executing code from program memory.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar RTC with alarm/correction, one watchdog timer, two DMA channels, and serial interfaces: up to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels - all configurable without external clock sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and low-energy interrupt latency. |
| Max Operating Frequency | 32 MHz; delivers 41 DMIPS for efficient sensor fusion and protocol stack execution in resource-constrained nodes. |
| Flash Memory | 64 KB code flash; supports self-programming with boot swap and flash shield window for secure firmware updates. |
| Data Flash | None (R5F101x series); eliminates data retention overhead but requires external EEPROM or FRAM for nonvolatile parameter storage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LDGFA#30 | Same package and memory (64 KB flash, 4 KB RAM), but adds 4 KB data flash and industrial temp grade (–40°C to +105°C). | Required where field-updatable calibration data or extended temperature operation beyond +85°C is needed. | Select when nonvolatile parameter storage or higher ambient tolerance is mandatory; otherwise R5F101LDAFA#30 offers lower cost and same core functionality. |
| R5F100LDAFA#30 | Identical pinout and package, but includes 8 KB data flash and same 64 KB code flash; otherwise identical peripherals and power specs. | Suitable for designs requiring embedded data logging or firmware parameter persistence without external memory. | Choose if data flash is essential; R5F101LDAFA#30 avoids data flash overhead and simplifies qualification for safety-critical firmware-only use cases. |
Compared with R5F101LDGFA#30 and R5F100LDAFA#30, the R5F101LDAFA#30 provides optimal cost/performance for firmware-centric industrial control where external nonvolatile storage is acceptable and +105°C operation is unnecessary.

FAQ
What is the operating temperature range for the R5F101LDAFA#30?
The R5F101LDAFA#30 is rated for industrial applications with an operating ambient temperature range of –40°C to +85°C. This specification is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80, Section 1.1), and the "D" suffix in the part number explicitly denotes this industrial-grade temperature capability.
Does the R5F101LDAFA#30 include data flash memory?
No, the R5F101LDAFA#30 does not include data flash memory. The "101" prefix in the part number identifies it as a member of the R5F101x series, which omits data flash - unlike the "100" series (e.g., R5F100LDAFA#30) that includes 8 KB. This is documented in the RL78/G13 datasheet Section 1.2 and memory configuration tables.
What package type and pin count does the R5F101LDAFA#30 use?
The R5F101LDAFA#30 uses a 64-pin LQFP package with 0.65-mm pitch, as indicated by the "FA" suffix (LQFP, 0.65-mm pitch) and "L" position (64-pin) in the part numbering scheme. Its mechanical outline matches JEDEC MS-026, and the package code is PLQP0064JA-A per Renesas' ordering guide.
Can the R5F101LDAFA#30 operate from a 1.8 V supply?
Yes, the R5F101LDAFA#30 supports a wide VDD range of 1.6 V to 5.5 V, fully including 1.8 V operation. This allows direct interfacing with 1.8 V logic families and compatibility with single-cell LiFePO₄ or dual-cell alkaline power sources without regulation - verified in the Absolute Maximum Ratings and Electrical Characteristics sections of the datasheet.
Which debug interface does the R5F101LDAFA#30 support?
The R5F101LDAFA#30 supports Renesas' single-wire debug (SWD) interface via the dedicated TOOLRxD/TOOLTxD pins (P11/P12), enabling full on-chip debugging, flash programming, and real-time trace without requiring a JTAG header. This is specified in the "On-chip debug function" feature list and pin configuration diagrams of the RL78/G13 datasheet.
