Product details
Overview
R5F101GLDNA#20 from Renesas is a 48-pin, 128 KB flash, data-flash-free RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 32 MHz max CPU speed, and integrated 10-bit ADC (26 channels), UART, I²C, and SPI interfaces - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F101GLDNA#20 datasheet, R5F101GLDNA#20 pinout, R5F101GLDNA#20 application, or R5F101GLDNA#20 equivalent, key selection criteria include its HWQFN-48 package, industrial-grade −40°C to +105°C operation (G-grade), absence of on-chip data flash, and support for SNOOZE mode for low-latency wake-up from ultra-low-power states.
Technical Context
The R5F101GLDNA#20 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features a unified 1 MB address space with four register banks. Its power architecture includes HALT, STOP, and SNOOZE modes, plus an on-chip LVD with 14 selectable voltage thresholds and POR circuitry.
Peripheral integration includes up to 16× 16-bit timers, one real-time clock with calendar/alarm/correction, 2–4-channel DMA, hardware multiplier/divider/MAC, and serial interfaces: 2–8 CSI (SPI-compatible), 2–4 UART/LIN, and 3–10 I²C channels - all configurable without external components.

FAQ
What is the maximum operating frequency of the R5F101GLDNA#20?
The R5F101GLDNA#20 supports a maximum CPU clock frequency of 32 MHz using its high-accuracy on-chip oscillator. This oscillator maintains ±1.0% accuracy across VDD = 1.8–5.5 V and TA = −20°C to +85°C, eliminating the need for external crystals in most timing-tolerant applications. The R5F101GLDNA#20 does not require external clock sources to achieve full performance.
Does the R5F101GLDNA#20 include on-chip data flash memory?
No, the R5F101GLDNA#20 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash (versus "100" which includes 4–8 KB). All 128 KB of on-chip non-volatile memory is allocated to code flash. Applications requiring parameter storage must use external EEPROM or utilize code flash sectors with wear-leveling firmware.
What package type and pin count does the R5F101GLDNA#20 use?
The R5F101GLDNA#20 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch), identified by the "NA" suffix in the part number. It is RoHS-compliant, lead-free, and rated MSL-3. This compact, thermally efficient package supports high-density PCB layouts and automated reflow assembly, distinguishing it from LQFP-48 variants like R5F101GLDFA#V0.
What is the operating temperature range for the R5F101GLDNA#20?
The R5F101GLDNA#20 is qualified for industrial operation from −40°C to +105°C, indicated by the "G" grade in its part number. This extended range supports deployment in harsh environments such as factory automation equipment, outdoor utility meters, and under-hood automotive subsystems - unlike "A" (−40°C to +85°C) or "D" (−40°C to +85°C) grade variants.
Which communication interfaces are supported by the R5F101GLDNA#20?
The R5F101GLDNA#20 integrates multiple serial interfaces: up to 8 CSI channels (SPI-compatible), up to 4 UART/LIN channels, and up to 10 I²C channels. Pin multiplexing allows concurrent use - for example, P10/P11/P12/P13 can configure one SPI + one I²C bus simultaneously. No external transceivers are required for basic UART or I²C operation, though RS-485 or CAN require companion ICs.
