Renesas R5F101GCANA#60

Overview

R5F101GCANA#60 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) and integrated peripherals including 10-bit ADC (26 channels), RTC, UART, I²C, SPI, and 16-bit timers - used in battery-powered industrial sensors and smart metering endpoints.

For engineers reviewing the R5F101GCANA#60 datasheet, R5F101GCANA#60 pinout, R5F101GCANA#60 application, or R5F101GCANA#60 equivalent, key selection criteria include its HWQFN-32 package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode for low-power sensor wake-up.

Technical Context

The R5F101GCANA#60 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), 14-level LVD, and background operation for data flash rewriting.

Its peripheral set includes up to 16 × 16-bit timers, 1 × real-time clock with calendar/alarm, 2–4 DMA channels, and serial interfaces (CSI, UART/LIN, I²C) configurable across multiple pins - enabling deterministic timing control and mixed-signal interfacing without external clock sources or flash controllers.

FAQ

What is the flash memory configuration of the R5F101GCANA#60?

The R5F101GCANA#60 contains 128 KB of on-chip code flash memory and no dedicated data flash memory (R5F101x series designation confirms data flash omission). It does include 12 KB of RAM for runtime variables and stack. Code flash supports block erase (1 KB), self-programming, and boot swap functionality - enabling field firmware updates without external tools. The absence of data flash reduces cost and die area while maintaining full code execution capability.

Does the R5F101GCANA#60 support real-time clock (RTC) functionality?

Yes, the R5F101GCANA#60 integrates a full-featured RTC with calendar support (99-year range), alarm interrupt, and clock correction function. It operates independently in STOP mode using the 32.768 kHz subsystem clock, drawing only 0.57 μA when active with LVD enabled. The RTC can be driven by an external crystal on CLKP/CLKM pins or the internal low-speed oscillator, ensuring accurate timekeeping for metering, scheduling, and timestamping in battery-powered applications.

What package type and pin count does the R5F101GCANA#60 use?

The R5F101GCANA#60 uses a 32-pin HWQFN package (5 × 5 mm, 0.5-mm pitch) with an exposed thermal pad. This package is designated by the "NA" suffix in Renesas' part numbering scheme and is compatible with standard QFN reflow profiles. Pin compatibility is maintained across all R5F101x series 32-pin variants (e.g., R5F101BCANA#60, R5F101CCANA#60), allowing drop-in replacement within the same memory configuration group.

How does the R5F101GCANA#60 achieve ultra-low power operation?

The R5F101GCANA#60 achieves ultra-low power through multiple hardware features: HALT mode (core stopped, peripherals active), STOP mode (all clocks halted except RTC/LVD), and SNOOZE mode (selected peripherals remain active during STOP for event-triggered wake-up). Its 66 μA/MHz active current and 0.57 μA STOP current are enabled by Renesas' proprietary low-leakage process and dynamic voltage scaling. These modes are controlled via dedicated system registers and require no external components - reducing BOM cost and PCB area.

Can the R5F101GCANA#60 interface directly with 1.8 V or 3.3 V peripherals?

Yes, the R5F101GCANA#60 supports different-potential I/O: its N-ch open-drain ports tolerate up to 6 V, and input thresholds are compatible with 1.8 V, 2.5 V, and 3.0 V logic families. When powered from 3.3 V, its I/O pins operate at 3.3 V levels with TTL-compatible inputs - enabling direct connection to common sensors, displays, and transceivers without level-shifting circuitry. This simplifies design and improves signal integrity in mixed-voltage systems.
