Product details
Overview
R5F101GEDFB#30 from Renesas is a 48-pin, 64 KB flash, data-flash-free RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated 10-bit ADC (26 channels), RTC, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GEDFB#30 datasheet, R5F101GEDFB#30 pinout, R5F101GEDFB#30 application, or R5F101GEDFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and support for background data flash programming via external library.
Technical Context
The R5F101GEDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz HS mode) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.
Peripherals include up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2–4× UART/LIN channels, 2–8× CSI (SPI-compatible) channels, and DMA controller with 2/4 channels enabling 2-clock transfers between SFR and RAM - all operating within the 1.6–5.5 V voltage range and -40°C to +85°C ambient specification.

FAQ
What is the maximum operating frequency of the R5F101GEDFB#30?
The R5F101GEDFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -40°C to +85°C. This enables 41 DMIPS performance while maintaining ultra-low active current (66 μA/MHz), making it ideal for real-time control in power-constrained environments where the R5F101GEDFB#30 balances speed and efficiency.
Does the R5F101GEDFB#30 include on-chip data flash memory?
No, the R5F101GEDFB#30 does not include on-chip data flash memory. The "101" in the part number explicitly indicates data flash is omitted, unlike "100" variants (e.g., R5F100GEDFB#30) which integrate 4 KB data flash. Firmware must use code flash sectors or external non-volatile memory for parameter storage - a confirmed design choice reflected in Renesas' official ordering matrix and datasheet memory tables for the R5F101GEDFB#30.
What package type and pin count does the R5F101GEDFB#30 use?
The R5F101GEDFB#30 uses a 48-pin LFQFP package with 7 mm × 7 mm body and 0.5 mm pin pitch (FB suffix per Renesas naming convention). This is confirmed in Table 1-1 of the R01DS0131EJ0380 datasheet under "48 pins / 48-pin plastic LFQFP", and matches the PLQP0048KF-A Renesas code. The #30 suffix denotes tray packaging for surface-mount assembly.
What is the operating temperature range for the R5F101GEDFB#30?
The R5F101GEDFB#30 is rated for industrial operation from -40°C to +85°C (D-grade), as indicated by the "D" in the fourth character position of the part number per Figure 1-1 of the datasheet. This is distinct from A-grade (-40°C to +85°C consumer) and G-grade (-40°C to +105°C industrial) variants - a confirmed specification validated against Renesas' official RL78/G13 ordering guide and device marking conventions for the R5F101GEDFB#30.
Which communication interfaces are supported by the R5F101GEDFB#30?
The R5F101GEDFB#30 supports UART (up to 4 channels, LIN-capable), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible, up to 8 channels), plus a dedicated simplified SPI (CSI) interface. These are fully documented in Section 1.1 Features and verified in the peripheral summary table of the R01DS0131EJ0380 datasheet - enabling robust sensor interfacing, display control, and wired/wireless modem communication in the R5F101GEDFB#30.
