Product details
Overview
R5F100JLDFA#V0 from Renesas is a 52-pin LQFP-0.65mm ultra-low-power 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, 10-bit ADC (26 channels), UART, I²C, CSI, and 16-bit timers - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100JLDFA#V0 datasheet, R5F100JLDFA#V0 pinout, R5F100JLDFA#V0 application, or R5F100JLDFA#V0 equivalent, key selection criteria include its 1.6–5.5 V operation, 66 μA/MHz active current, STOP mode at 0.57 μA, and support for LIN-bus communication via UART.
Technical Context
The R5F100JLDFA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and supports SNOOZE mode for low-latency peripheral wake-up without CPU intervention.
Its memory subsystem includes 256 KB code flash (1 KB block size, security lock), 8 KB background-operable data flash (1M rewrite cycles), and 20 KB SRAM - with dedicated RAM regions (e.g., FAF00H) reserved for flash library self-programming operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101JLDFA#V0 | No data flash (0 KB); same core, package, and peripheral set | Not suitable for field firmware updates or parameter storage requiring nonvolatile retention | Select when boot code is immutable and configuration is stored externally or in EEPROM |
| R5F100JLGFA#V0 | Same flash/RAM but rated for −40°C to +105°C (G-grade industrial) | Required for under-hood automotive or high-temp industrial enclosures | Choose for extended ambient temperature environments where thermal derating is critical |
Compared with R5F100JLDFA#V0, R5F101JLDFA#V0 removes data flash to reduce cost and die size but sacrifices in-field reconfiguration capability, while R5F100JLGFA#V0 maintains identical functionality with enhanced thermal robustness - making it ideal for harsher deployments without architectural change.

FAQ
What is the operating voltage range of the R5F100JLDFA#V0?
The R5F100JLDFA#V0 operates from 1.6 V to 5.5 V, enabling direct compatibility with single-cell Li-ion, 3.3 V, and 5 V system rails. This wide range supports brown-out resilience and simplifies power design in mixed-voltage applications such as smart meters with backup coin cells and main AC-DC supplies.
Does the R5F100JLDFA#V0 support LIN bus communication?
Yes, the R5F100JLDFA#V0 supports LIN bus communication through its UART peripherals, which include LIN-break detection and sync-byte handling per LIN 2.x specifications. This capability is confirmed in the RL78/G13 datasheet section "Serial Interface" and enables use in automotive body electronics and industrial sub-networks.
How much SRAM is available on the R5F100JLDFA#V0, and is any reserved for firmware functions?
The R5F100JLDFA#V0 includes 20 KB of on-chip SRAM. A fixed 256-byte region starting at address FAF00H is reserved for the flash self-programming library during data flash writes - this allocation is documented in the RL78/G13 datasheet's "Flash Library RAM Usage" table and must be excluded from application use.
What is the maximum ADC resolution and channel count supported by the R5F100JLDFA#V0?
The R5F100JLDFA#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It also provides an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated ANI pins - enabling precision sensor measurement without external components.
Is the R5F100JLDFA#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 52-pin LQFP-0.65mm package (e.g., R5F100JCAFA#V0, R5F100JLAFA#V0) share identical pinouts and electrical characteristics. This allows hardware reuse across memory variants - for example, upgrading from 128 KB to 256 KB flash requires only firmware and BOM changes, not PCB redesign.
