Product details
Overview
R5F101GCANA#U0 from Renesas is a 32-bit RL78/G13 microcontroller with 128 KB flash memory, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 16-bit A/D converter (10-bit resolution, 26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GCANA#U0 datasheet, R5F101GCANA#U0 pinout, R5F101GCANA#U0 application, or R5F101GCANA#U0 equivalent, key selection criteria include its 24-pin HWQFN package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated low-power timing and analog-peripheral subsystems for energy-constrained embedded control.
Technical Context
The R5F101GCANA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction functions, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 2–4 UART/LIN-capable serial interfaces, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register-based control without external clock dependencies.

FAQ
What is the flash memory configuration of the R5F101GCANA#U0?
The R5F101GCANA#U0 contains 128 KB of on-chip code flash memory with 1 KB erasable blocks and no integrated data flash - consistent with the R5F101x series designation indicating data flash omission. This configuration prioritizes code density and cost efficiency over in-field parameter storage, making it ideal for fixed-function firmware deployments where self-programming is limited to application code updates only.
Does the R5F101GCANA#U0 support real-time clock functionality?
Yes, the R5F101GCANA#U0 integrates a full-featured real-time clock (RTC) with calendar support (year/month/day/hour/min/sec), alarm interrupt generation, and clock correction capability. It operates independently in STOP mode using the 32.768 kHz subsystem clock, drawing only 0.57 μA - enabling time-stamped data logging and scheduled wake-up events without external RTC ICs.
What package type and pin count does the R5F101GCANA#U0 use?
The R5F101GCANA#U0 uses a 24-pin HWQFN package (4 × 4 mm, 0.5 mm pitch) with wettable flanks, designated by the "NA" suffix in Renesas' part numbering scheme. This compact, thermally efficient package supports automated optical inspection and is optimized for space-constrained PCB layouts in portable and industrial equipment.
How does the R5F101GCANA#U0 achieve ultra-low power consumption?
The R5F101GCANA#U0 achieves ultra-low power via multiple hardware-optimized states: 66 μA/MHz active current, 0.57 μA STOP mode (RTC + LVD active), and configurable HALT/SNOOZE modes. Its RL78 core dynamically scales instruction speed from 32 MHz down to 32.768 kHz, and on-chip power-on-reset (POR) and voltage detector (LVD) eliminate external supervision circuitry - collectively reducing system-level power design complexity.
Which serial communication protocols are supported by the R5F101GCANA#U0?
The R5F101GCANA#U0 supports UART (with LIN-bus compliance), I²C/Simplified I²C, and CSI (Renesas' SPI-compatible interface) across shared multi-function pins. These protocols operate concurrently with independent clock sources and buffer controls, enabling simultaneous communication with displays (I²C), sensors (UART), and memory (CSI) without software arbitration overhead.
