Product details
Overview
R5F101GEDFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz. It integrates a real-time clock, 10-bit ADC (26 channels), UART/LIN, I²C, SPI, 16-bit timers, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for embedded control in industrial sensor nodes and battery-powered HMI.
For engineers reviewing the R5F101GEDFB#V0 datasheet, R5F101GEDFB#V0 pinout, R5F101GEDFB#V0 application, or R5F101GEDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash rewriting via BGO.
Technical Context
The R5F101GEDFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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 64 KB code flash (1 KB block size), 4 KB RAM, and no on-chip data flash - distinguishing it from R5F100x variants.
Peripheral integration includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART/LIN interfaces, three I²C channels, two CSI (SPI-compatible) interfaces, eight 16-bit timers, and DMA controller with 2 channels - all managed under a unified low-power architecture supporting HALT, STOP, and SNOOZE modes.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GEDFB#V0 | Same package and pinout; includes 4 KB data flash and supports background operation (BGO) | Required where field-upgradable parameter storage (e.g., calibration data) must persist across resets without halting CPU | Select when non-volatile parameter retention with concurrent program execution is mandatory |
| R5F101GEAFB#V0 | 48-pin LQFP-0.65 mm pitch (PLQP0048KB-B); identical memory and peripheral set but different footprint | Preferred for legacy PCBs designed for standard LQFP pitch or where thermal pad access is not required | Choose for compatibility with existing LQFP-0.65 mm layout or simplified reflow profile |
Compared with R5F100GEDFB#V0, the R5F101GEDFB#V0 trades data flash capability for lower cost and reduced firmware complexity, while versus R5F101GEAFB#V0 it offers improved thermal dissipation and higher I/O drive strength via the 0.5 mm pitch LFQFP package.

FAQ
What is the operating temperature range for the R5F101GEDFB#V0?
The R5F101GEDFB#V0 is rated for industrial operation from –40°C to +85°C (D-grade), validated across the full voltage range (1.6–5.5 V) and all low-power modes. This specification is confirmed in the RL78/G13 datasheet Rev.3.80 Section 1.1 and applies specifically to the #V0 tray-packaged LFQFP variant.
Does the R5F101GEDFB#V0 include on-chip data flash memory?
No, the R5F101GEDFB#V0 does not integrate data flash memory. The "101" in the part number explicitly denotes absence of on-chip data flash per Figure 1-1 of the RL78/G13 datasheet. Code flash (64 KB) supports self-programming, but persistent parameter storage requires external EEPROM or FRAM.
What debug interface does the R5F101GEDFB#V0 support?
The R5F101GEDFB#V0 supports Renesas E20 emulator-based on-chip debugging via the dedicated TOOLRxD/TOOLTxD pins (P11/P12) and SWD-compatible serial wire debug protocol. No JTAG TAP is implemented; debug access requires the E20 or compatible toolchain with RL78-specific firmware loader.
Can the R5F101GEDFB#V0 drive a 32.768 kHz crystal for RTC operation?
Yes, the R5F101GEDFB#V0 includes a dedicated low-speed on-chip oscillator circuit connected to pins P30 (XT1) and P31 (XT2) for driving standard 32.768 kHz tuning-fork crystals. This enables full RTC functionality including calendar, alarm, and automatic clock correction - confirmed in Section 1.1 "Real-time clock" of the datasheet.
What is the maximum ADC sampling rate achievable with the R5F101GEDFB#V0?
The R5F101GEDFB#V0's 10-bit ADC achieves a maximum conversion time of 1.2 μs per sample (833 kSPS theoretical), based on the 32 MHz system clock and minimum 38-clock-cycle conversion cycle specified in the RL78/G13 hardware manual. Actual sustained rate depends on trigger source and result register readout overhead.
