Product details
Overview
R5F100JEAFA#V0 from Renesas is a 52-pin LQFP-0.65mm, 256 KB flash, 8 KB data flash, 20 KB RAM RL78/G13 16-bit MCU with ultra-low-power operation (66 μA/MHz), real-time clock, 10-bit ADC (24 channels), and integrated UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100JEAFA#V0 datasheet, R5F100JEAFA#V0 pinout, R5F100JEAFA#V0 application, or R5F100JEAFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, -40°C to +85°C industrial temperature grade, 256 KB code flash with self-programming, RTC calendar function, and support for SNOOZE mode wake-up via external interrupt or peripheral event.
Technical Context
The R5F100JEAFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and a calendar-capable real-time clock with alarm and clock correction.
Power management includes HALT, STOP, and SNOOZE modes; voltage detector (LVD) with 14 selectable levels; and on-chip POR. The DMA controller supports 4 channels with 2-clock transfers between SFR and RAM, enabling efficient peripheral-to-memory data movement without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101JEAFA#V0 | No data flash (0 KB); identical pinout, peripherals, and code flash size (256 KB) | Not suitable where persistent parameter storage or firmware update logging is required | Select when data retention needs are met by external EEPROM or when cost reduction outweighs embedded data flash benefit |
| R5F100JGAFA#V0 | 128 KB code flash, same 8 KB data flash, 12 KB RAM, identical package and peripheral set | Lower memory margin for complex protocol stacks or GUI frameworks | Choose for cost-sensitive designs with verified memory headroom below 256 KB; retains full compatibility for migration path |
Compared with R5F100JEAFA#V0, R5F101JEAFA#V0 removes data flash to reduce cost and die size but sacrifices in-field configuration storage, while R5F100JGAFA#V0 offers proven functionality at lower memory capacity - both retain identical 52-pin LQFP packaging and industrial temperature rating for drop-in evaluation.

FAQ
What is the maximum operating frequency and performance of the R5F100JEAFA#V0?
The R5F100JEAFA#V0 operates at up to 32 MHz with an RL78 CPU core delivering 41 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across 1.8–5.5 V and -40°C to +85°C, eliminating need for external crystals in many timing-critical applications. The R5F100JEAFA#V0 achieves this performance while consuming only 66 μA per MHz in active mode.
Does the R5F100JEAFA#V0 include integrated data flash memory, and what is its endurance?
Yes, the R5F100JEAFA#V0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing full CPU execution from program memory during rewrites - essential for reliable firmware updates and runtime parameter logging without system interruption. This capability is fully implemented in the R5F100JEAFA#V0.
What package type and pin count does the R5F100JEAFA#V0 use?
The R5F100JEAFA#V0 uses a 52-pin LQFP package with 0.65-mm pitch (10 × 10 mm body), designated by the "FA" suffix and "#V0" tray packaging code. This package is RoHS-compliant, moisture sensitivity level 3, and compatible with standard surface-mount assembly processes. Pin compatibility is maintained across all RL78/G13 52-pin LQFP variants, including R5F100JEAFA#V0 and R5F100JGAFA#V0.
Can the R5F100JEAFA#V0 operate in extended temperature ranges such as -40°C to +105°C?
No, the R5F100JEAFA#V0 is specified for industrial operation from -40°C to +85°C (suffix "D" grade). It does not support the -40°C to +105°C range (suffix "G" grade), which requires variants like R5F100JEGFA#V0. The "E" in R5F100JEAFA#V0 explicitly denotes the 256 KB flash variant within the +85°C industrial temperature grade - confirmed in Renesas' official part numbering guide and datasheet Table 1-1.
What development tools and debug interfaces are supported by the R5F100JEAFA#V0?
The R5F100JEAFA#V0 supports Renesas E2 studio IDE with CS+ compiler, and hardware debugging via single-wire debug (SWD) using the E2 Lite or E2 emulator. On-chip debug functionality is fully integrated - no external debug header or JTAG adapter is required. Flash programming, real-time trace, and breakpoint debugging are all enabled directly through the SWD interface on dedicated pins (e.g., RES#, P00, P01), as documented in the R5F100JEAFA#V0 hardware manual.
