Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101JLDFA#50 | Same silicon, embossed tape packaging instead of tray; identical electrical specs and pinout | No functional difference; selected for automated SMT line compatibility | Choose #50 for high-volume pick-and-place; #30 preferred for prototyping and small-batch assembly |
| R5F100JLDFA#30 | Same package and pinout, but includes 8 KB data flash (R5F101JLDFA#30 has none) | Required where field firmware updates or parameter storage exceed RAM capacity | Select R5F100JLDFA#30 only if data flash usage is mandatory; R5F101JLDFA#30 reduces cost where BGO logging is unnecessary |

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101JLDFA#30?
The R5F101JLDFA#30 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This is achieved with the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling real-time control tasks such as motor commutation or sensor fusion without external acceleration.
Does the R5F101JLDFA#30 include data flash memory, and what are its endurance specifications?
No, the R5F101JLDFA#30 does not include data flash memory - it belongs to the "101" series where data flash is omitted. In contrast, the "100" series (e.g., R5F100JLDFA#30) provides 8 KB data flash rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V. The R5F101JLDFA#30 relies on its 20 KB SRAM and code flash for runtime data storage.
What low-power modes are supported by the R5F101JLDFA#30, and what is the lowest achievable current consumption?
The R5F101JLDFA#30 supports HALT, STOP, and SNOOZE modes. Its lowest current draw is 0.57 μA in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active - verified at VDD = 3.0 V and TA = 25°C. This enables decade-long operation on coin-cell batteries in maintenance-free sensor deployments.
Can the R5F101JLDFA#30 execute code while rewriting its flash memory?
The R5F101JLDFA#30 cannot execute code from flash during code flash erase/write operations. However, it supports background operation (BGO) for data flash - but since R5F101JLDFA#30 lacks data flash, BGO is not applicable. Code updates require halting execution or using boot-swap firmware architecture with dual banks.
What is the pin count, package type, and RoHS compliance status of the R5F101JLDFA#30?
The R5F101JLDFA#30 uses a 52-pin LQFP package (10 mm × 10 mm, 0.65 mm pitch) with PLQP0052JA-A footprint. It is RoHS-compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. The package includes an exposed thermal pad for enhanced heat dissipation in industrial environments.
