Product details
Overview
R5F100SHDFB#10 from Renesas is a 128-pin LFQFP (0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and operation from −40°C to +85°C. It integrates a real-time clock, 10-bit 26-channel ADC, 16-bit timers (16 channels), UART/LIN, I²C, CSI, DMA, and ultra-low-power modes (0.57 μA in RTC+LVD mode). It targets battery-powered industrial control panels requiring deterministic timing and secure firmware updates.
For engineers reviewing the R5F100SHDFB#10 datasheet, R5F100SHDFB#10 pinout, R5F100SHDFB#10 application, or R5F100SHDFB#10 equivalent, key selection criteria include its 128-pin LFQFP-0.5mm package, integrated data flash with 1M rewrite cycles, 32 MHz max CPU speed at 1.6–5.5 V supply, and support for background data flash programming during code execution.
Technical Context
The R5F100SHDFB#10 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB on-chip code flash (1 KB block size, security-protected erase/write), 8 KB data flash with background operation (BGO), and 12 KB RAM - enabling simultaneous program execution and nonvolatile parameter storage.
Peripherals are tightly coupled to low-power operation: the 16-bit timer array supports input capture/compare/PWM across 16 channels; the 10-bit ADC provides up to 26 analog inputs with internal 1.45 V reference and temperature sensor; and serial interfaces include 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN ports, and 2–8 CSI (SPI-compatible) channels - all configurable under HALT, STOP, and SNOOZE power modes.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100SHDFB#10?
The R5F100SHDFB#10 operates at up to 32 MHz with a typical current draw of 66 μA per MHz in active mode. At full speed, this equates to approximately 2.1 mA (32 MHz × 66 μA/MHz) under typical conditions. Its ultra-low-power STOP mode draws only 0.57 μA when retaining RTC and LVD functionality - making it ideal for intermittent-sensing applications.
Does the R5F100SHDFB#10 support in-system programming and secure firmware updates?
Yes, the R5F100SHDFB#10 supports full in-system programming via its on-chip debug interface and includes hardware-enforced security features: flash block erase/write prohibition, boot swap functionality for fail-safe updates, and a flash shield window that restricts access to designated memory regions - ensuring authenticated and atomic firmware upgrades.
How many analog input channels does the R5F100SHDFB#10 ADC support, and what references are available?
The R5F100SHDFB#10 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external VDD as reference, an internal 1.45 V precision reference, and includes a calibrated on-chip temperature sensor - enabling accurate thermal compensation and sensor calibration without external components.
Can the R5F100SHDFB#10 execute code while rewriting data flash memory?
Yes, the R5F100SHDFB#10 supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from code flash while simultaneously erasing or programming data flash - allowing uninterrupted real-time processing during parameter logging, configuration updates, or firmware patching.
What package type and pin count does the R5F100SHDFB#10 use, and is it RoHS compliant?
The R5F100SHDFB#10 uses a 128-pin LFQFP package with 0.5-mm pitch and 14 × 20 mm body size (Renesas code PLQP0128KD-A). It is lead-free and RoHS compliant, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for standard surface-mount assembly processes.
