Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101JLAFA#V0 | No data flash memory (0 KB); identical core, peripherals, and package | Not suitable where field firmware updates or parameter storage are required | Select when boot code and configuration are stored externally or fixed at production |
| R5F100GLAFA#V0 | 48-pin LQFP, 128 KB flash, 8 KB data flash, 12 KB RAM - smaller footprint, lower memory | Better fit for cost-sensitive, space-constrained designs with reduced code/data requirements | Choose when application fits within 128 KB flash and 12 KB RAM, and PCB layout allows 48-pin LQFP |
Compared with R5F100JLAFA#V0, R5F101JLAFA#V0 removes data flash to reduce cost and test complexity but sacrifices in-field reconfiguration capability, while R5F100GLAFA#V0 trades pin count and memory for compactness - making it viable only when full 52-pin I/O and 256 KB code space are not required.

FAQ
What is the maximum operating frequency and corresponding current consumption for R5F100JLAFA#V0?
R5F100JLAFA#V0 operates up to 32 MHz using the high-speed on-chip oscillator with ±1.0% accuracy (1.8–5.5 V, –20 to +85°C). At this frequency, typical active current is 66 μA/MHz, equating to ~2.1 mA total. In STOP mode with RTC and LVD active, current drops to 0.57 μA - verified per R01DS0131EJ0380 Rev.3.80, Page 1.
Does R5F100JLAFA#V0 support in-system programming and secure firmware updates?
Yes, R5F100JLAFA#V0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for firmware security. Self-programming with boot swap functionality enables safe dual-image updates - confirmed in Section 1.1 Features and Flash Library RAM mapping (Page 3).
How many serial communication interfaces does R5F100JLAFA#V0 integrate, and which protocols are supported?
R5F100JLAFA#V0 integrates up to 2 CSI/SPI channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - though actual channel count depends on pin multiplexing. UART channels support LIN 2.2 compliance, and I²C includes clock stretching and multi-master arbitration - detailed in Section 1.1 Serial Interface (Page 1).
What ADC resolution, input count, and reference options are available on R5F100JLAFA#V0?
R5F100JLAFA#V0 features a 10-bit successive-approximation ADC with 26 analog input channels. It supports external reference or internal 1.45 V reference (selectable only in HS mode), and includes an integrated temperature sensor - specified in Section 1.1 A/D Converter (Page 1) and validated in memory configuration tables (Page 2).
Is R5F100JLAFA#V0 qualified for industrial temperature range, and what packaging options accompany the #V0 suffix?
Yes, R5F100JLAFA#V0 is rated for –40°C to +85°C (A-grade industrial specification) and ships in 52-pin LQFP (10 × 10 mm, 0.65-mm pitch) in tray packaging - as defined by the "#V0" suffix per Figure 1-1 and Table 1-1 (Pages 3–4). The "A" in the part number confirms consumer/industrial grade (not extended G-grade).
