Product details
Overview
R5F101GLDFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and operation up to 32 MHz (41 DMIPS). It features ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and operates across –40°C to +105°C for industrial control, sensor nodes, and battery-powered HMI.
For engineers reviewing the R5F101GLDFB#X0 datasheet, R5F101GLDFB#X0 pinout, R5F101GLDFB#X0 application, or R5F101GLDFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of data flash, industrial temperature rating (G-grade), and support for low-power modes including STOP, HALT, and SNOOZE - critical for energy-constrained embedded designs.
Technical Context
The R5F101GLDFB#X0 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 map includes 1 MB address space, on-chip RAM banked across four register banks, and flash memory organized in 1 KB blocks with security lock and self-programming capability.
Peripheral integration includes dual DMA channels (2 clocks per 8/16-bit transfer), hardware multiplier/divider/MAC, 16-bit timers (up to 16 channels), 12-bit interval timer, calendar-based RTC with alarm and correction, watchdog timer with dedicated low-speed oscillator, and configurable I/O ports supporting 1.8/2.5/3.0 V level shifting - all optimized for deterministic real-time response and mixed-signal interfacing in resource-constrained systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GLAFB#X0 | Same 48-pin LFQFP package, identical 128 KB flash/12 KB RAM, but with data flash (8 KB) enabled | Required where firmware-over-the-air (FOTA) or parameter storage in nonvolatile memory is needed | Select R5F101GLAFB#X0 if data logging, calibration storage, or bootloader update persistence is required |
| R5F101GJAFB#X0 | 48-pin LQFP (10 × 10 mm, 0.65-mm pitch), same flash/RAM, no data flash, consumer-grade (A: –40°C to +85°C) | Lower-cost alternative for non-industrial environments with relaxed thermal requirements | Choose R5F101GJAFB#X0 only when operating ambient stays ≤+85°C and PCB layout allows larger footprint |
Compared with R5F101GLDFB#X0, R5F101GLAFB#X0 adds 8 KB data flash at no performance or package penalty - ideal for field-upgradable systems - while R5F101GJAFB#X0 trades industrial temperature range and compact LFQFP for lower cost and standard LQFP compatibility, requiring thermal derating and board re-layout.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101GLDFB#X0?
The R5F101GLDFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in this mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - all verified in the R01DS0131EJ0380 datasheet.
Does the R5F101GLDFB#X0 include data flash memory?
No, the R5F101GLDFB#X0 does not include data flash memory. As indicated by the "101" prefix in its part number (per Figure 1-1 of R01DS0131EJ0380), this variant provides 128 KB of code flash and 12 KB of RAM but omits the 4–8 KB data flash found in "100" series variants like R5F101GLAFB#X0.
What package type and pin count does the R5F101GLDFB#X0 use?
The R5F101GLDFB#X0 uses a 48-pin LFQFP package with 7 × 7 mm body size and 0.5-mm lead pitch (Renesas code PLQP0048KF-A). The "FB" suffix in the part number explicitly denotes LFQFP-0.5mm, and "#X0" indicates embossed tape packaging - confirmed in Table 1-1, page 8 of R01DS0131EJ0380.
What is the operating temperature range certified for the R5F101GLDFB#X0?
The R5F101GLDFB#X0 is rated for industrial operation from –40°C to +105°C, designated by the "G" suffix in its part number per Figure 1-1 of R01DS0131EJ0380. This qualifies it for deployment in harsh environments such as factory automation, power infrastructure, and outdoor metering without derating.
Which communication interfaces are supported by the R5F101GLDFB#X0?
The R5F101GLDFB#X0 supports up to 8 CSI (SPI-compatible) channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - all configurable via shared pins (e.g., P10–P13). These interfaces operate independently with separate clock sources, enabling concurrent multi-protocol communication without software arbitration.
