Product details
Overview
R5F101JJAFA#30 from Renesas is a 52-pin LQFP-0.65mm microcontroller in the RL78/G13 family, featuring 64 KB flash memory, 4 KB data flash, 4 KB RAM, and operation from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), UART/LIN, I²C, SPI, RTC, and 16-bit timers - deployed in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101JJAFA#30 datasheet, R5F101JJAFA#30 pinout, R5F101JJAFA#30 application, or R5F101JJAFA#30 equivalent, key selection criteria include its no-data-flash configuration, industrial-grade -40°C to +85°C temperature range (D-grade), LQFP-52 package with 0.65 mm pitch, and support for background data flash rewriting during program execution.
Technical Context
The R5F101JJAFA#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 includes 1 MB address space, on-chip debug, and self-programming with boot swap and flash shield window functions.
Power management includes on-chip POR and 14-level LVD with interrupt/reset selection; peripheral integration covers DMA (2 channels), 16×16/32÷32 multiplier/divider, and simplified SPI (CSI), UART/LIN (up to 4 channels), and I²C (up to 10 channels) - all operating within the same 1.6–5.5 V supply range as the core.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100JJAFA#30 | Same package and pinout, but includes 4 KB data flash and higher RAM (4 KB vs. 4 KB - identical RAM; data flash added) | Required where background data rewriting (BGO) or >1M write cycles to nonvolatile storage is needed | Select R5F100JJAFA#30 if firmware must store calibration data or logs internally without external EEPROM |
| R5F101JJAFA#50 | Identical silicon and functionality; differs only in packaging - embossed tape (#50) vs. tray (#30) | No functional difference; choice driven by SMT line feed requirements and reel vs. tray handling | Choose R5F101JJAFA#50 for automated pick-and-place with tape-and-reel feeders; #30 for manual or tray-based assembly |
Compared with R5F101JJAFA#30, R5F100JJAFA#30 adds data flash for embedded nonvolatile storage but increases cost and power in active modes, while R5F101JJAFA#50 offers identical electrical and thermal performance with logistics-optimized packaging - making the #30 variant optimal for low-volume or prototype builds requiring tray delivery.

FAQ
Does R5F101JJAFA#30 include on-chip data flash memory?
No, R5F101JJAFA#30 does not include data flash memory. The '1' in the second digit of the part number (R5F101JJAFA#30) explicitly denotes "data flash not provided", as confirmed in Section 1.2 of the RL78/G13 datasheet R01DS0131EJ0380. This distinguishes it from R5F100x variants which include 4–8 KB data flash.
What is the maximum operating temperature rating for R5F101JJAFA#30?
The R5F101JJAFA#30 is rated for operation from –40°C to +85°C, corresponding to the 'D' grade in Renesas' marking convention (see Figure 1-1). This industrial temperature range is verified in Table 1-1 and applies across all electrical specifications in the datasheet.
Which development tools support debugging of R5F101JJAFA#30?
R5F101JJAFA#30 is supported by Renesas E2 emulator and CS+ IDE for RL78. Debugging uses the TOOLRxD/TOOLTxD pins (P11/P12) in SWD-like serial wire debug mode, requiring no JTAG header - enabling compact PCB layouts while maintaining full flash programming and real-time trace capability.
Can R5F101JJAFA#30 operate from a 1.8 V supply?
Yes, R5F101JJAFA#30 supports 1.6 V to 5.5 V single-supply operation. At 1.8 V, it operates up to 8 MHz (per datasheet Section 2.3.1), enabling ultra-low-power sensor readout and sleep-wake cycles without external regulators - ideal for coin-cell or energy-harvesting systems.
Is R5F101JJAFA#30 pin-compatible with other RL78/G13 52-pin LQFP variants?
Yes, all RL78/G13 52-pin LQFP variants - including R5F100Jx and R5F101Jx families in FA package - share identical pinouts and footprint. This allows hardware reuse across flash-size and data-flash-enabled variants, reducing design iteration time when scaling firmware requirements.
