Product details
Overview
R5F100LEDFA#30 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz), real-time clock, 10-bit ADC (26 channels), and integrated UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LEDFA#30 datasheet, R5F100LEDFA#30 pinout, R5F100LEDFA#30 application, or R5F100LEDFA#30 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade, on-chip LVD with 14-level interrupt/reset, background data flash rewriting (1M rewrite cycles), and HALT/STOP/SNOOZE low-power modes for energy-constrained embedded designs.
Technical Context
The R5F100LEDFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-mode RTC with alarm/correction, and watchdog timer powered by dedicated low-speed oscillator.
Its memory subsystem includes 128 KB code flash (1 KB block size, security-protected erase/write), 8 KB data flash with background operation (BGO), and 12 KB SRAM - with flash library RAM usage starting at address FEF00H. Power management features POR, LVD (14 selectable voltage thresholds), and multi-level low-power modes tightly coupled to peripheral clock gating.

FAQ
What is the maximum operating frequency and performance of the R5F100LEDFA#30?
The R5F100LEDFA#30 operates up to 32 MHz with the high-speed on-chip oscillator, delivering 41 DMIPS. Its RL78 CPU core supports variable instruction execution time - from 0.03125 μs at full speed to 30.5 μs at 32.768 kHz - enabling dynamic trade-offs between performance and power. This flexibility makes the R5F100LEDFA#30 ideal for applications like sensor polling and real-time actuation where burst processing and deep sleep coexist.
Does the R5F100LEDFA#30 include an integrated real-time clock (RTC)?
Yes, the R5F100LEDFA#30 integrates a full-featured RTC with calendar function supporting 99 years, alarm interrupt, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock, drawing only 0.57 μA - critical for timestamping events in battery-powered devices without external RTC components. The RTC is accessible via dedicated registers and requires no external crystal if driven by an external 32.768 kHz clock source.
How much data flash memory does the R5F100LEDFA#30 provide, and what are its key characteristics?
The R5F100LEDFA#30 includes 8 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing CPU code execution from program memory while rewriting data flash - essential for seamless firmware updates and nonvolatile parameter storage. The R5F100LEDFA#30 uses flash library RAM starting at address FEF00H, which must be reserved in the linker configuration.
What low-power modes are supported by the R5F100LEDFA#30, and how do they differ?
The R5F100LEDFA#30 supports HALT (CPU halted, peripherals active), STOP (all clocks stopped except RTC/LVD), and SNOOZE (selective peripheral wake-up with CPU in HALT). Each mode targets distinct use cases: HALT for rapid wake-up response, STOP for minimal current draw (0.57 μA), and SNOOZE for autonomous peripheral-triggered wake-up (e.g., ADC conversion complete or UART receive). All modes retain RAM and register contents, ensuring deterministic restart behavior in the R5F100LEDFA#30.
Is the R5F100LEDFA#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LEDFA#30 is pin-compatible with all 64-pin LQFP RL78/G13 variants sharing the PLQP0064JA-A package, including R5F100LCDFA#30 (64 KB flash) and R5F100LLDFA#30 (512 KB flash). Pin assignments for power, reset, clock, and primary I/O are consistent across the family. However, peripheral function mapping (e.g., UART vs. CSI channel assignment) may vary - always verify the specific pin function table in the R5F100LEDFA#30 datasheet before hardware design reuse.
