Product details
Overview
R5F100SJDFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with 192 KB flash, 8 KB data flash, and 16 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 52-pin LFQFP package, and integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100SJDFB#30 datasheet, R5F100SJDFB#30 pinout, R5F100SJDFB#30 application, or R5F100SJDFB#30 equivalent, key selection criteria include its 52-pin LFQFP-0.65mm footprint, -40°C to +85°C industrial temperature grade (D suffix), data flash background rewriting capability, and support for LIN-compliant UART channels in resource-constrained embedded control designs.
Technical Context
The R5F100SJDFB#30 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 dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog/RTC.
Peripherals include 8-channel 16-bit timers, 1-channel 12-bit interval timer, calendar-mode RTC with alarm/correction, 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all accessible via 42 programmable I/O pins with N-ch open-drain, TTL input, and pull-up options.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101SJDFB#30 | No data flash (0 KB); identical core, peripherals, and package | Unsuitable for firmware-over-the-air or runtime parameter storage; requires external EEPROM/NVRAM | Select when data retention needs are met externally and cost reduction is prioritized |
| R5F100SJGFB#30 | Same memory and peripherals, but rated for -40°C to +105°C (G grade) | Required for under-hood automotive or high-ambient industrial enclosures exceeding +85°C | Choose only if extended temperature operation is mandatory; otherwise, D-grade R5F100SJDFB#30 offers better cost/performance balance |
Compared with R5F100SJDFB#30, R5F101SJDFB#30 removes data flash to reduce cost and die size but sacrifices in-field update flexibility, while R5F100SJGFB#30 trades wider temperature tolerance for higher unit cost - making R5F100SJDFB#30 optimal for standard industrial environments where data flash and 85°C operation are both required.

FAQ
What is the maximum operating frequency and associated DMIPS rating of the R5F100SJDFB#30?
The R5F100SJDFB#30 operates at a maximum frequency of 32 MHz and delivers 41 DMIPS of processing performance. This metric is measured using the EEMBC CoreMark benchmark and reflects real-world throughput for control-oriented embedded code, including interrupt handling and peripheral register access latency inherent to the RL78 CISC pipeline.
Does the R5F100SJDFB#30 include on-chip data flash memory, and what is its endurance specification?
Yes, the R5F100SJDFB#30 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8–5.5 V. This memory supports background operation (BGO), allowing program execution from code flash while data flash is being rewritten - a key enabler for robust firmware update and data logging implementations.
What package type and pin count does the R5F100SJDFB#30 use, and what is its thermal rating?
The R5F100SJDFB#30 uses a 52-pin LFQFP package (10 × 10 mm, 0.65-mm pitch) and is rated for industrial temperature operation from –40°C to +85°C (D-grade). Its PLQP0052JA-A/PLQP0052JD-B footprint is compatible with standard reflow profiles and supports automated optical inspection (AOI) due to gull-wing lead geometry.
How many analog input channels does the R5F100SJDFB#30 support, and what ADC resolution is provided?
The R5F100SJDFB#30 supports up to 26 analog input channels with a 10-bit successive-approximation ADC. It includes an internal 1.45 V reference voltage and an integrated temperature sensor - both usable simultaneously with external analog inputs - enabling compact, calibration-free sensor front-ends for environmental monitoring and motor control applications.
Which serial communication protocols are natively supported by the R5F100SJDFB#30 without external transceivers?
The R5F100SJDFB#30 natively supports UART (with LIN bus compliance), I²C (including Simplified I²C), and CSI (SPI-compatible serial interface) across configurable pin sets. No external transceivers are needed for point-to-point UART/LIN or multi-drop I²C communication; CSI provides hardware-accelerated SPI master/slave operation with DMA support for high-throughput sensor data acquisition.
