Product details
Overview
R5F100GCANA#20 from Renesas is a 24-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GCANA#20 datasheet, R5F100GCANA#20 pinout, R5F100GCANA#20 application, or R5F100GCANA#20 equivalent, key selection criteria include its 24-pin HWQFN-0.5mm-pitch package, -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, and BGO-capable data flash for firmware updates without halting execution.
Technical Context
The R5F100GCANA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm functions, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes up to 16 × 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and DMA controller with 2/4 channels enabling zero-wait-state transfers between SFR and RAM in just two clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GCANA#00 | Identical silicon; differs only in packaging - supplied in embossed tape instead of tray | Same functional use; optimized for automated SMT placement with tape-and-reel feeders | Select #00 for high-volume production lines requiring tape-fed pick-and-place; #20 preferred for prototyping or low-volume assembly |
| R5F101GCANA#20 | Omits data flash (0 KB); retains same 128 KB code flash, 12 KB RAM, and peripheral set | Suitable where firmware updates occur only via external host or field programming - no runtime self-write requirement | Choose when BGO and data flash endurance are unnecessary; reduces cost and simplifies flash management firmware |
Compared with R5F100GCANA#20, the #00 variant offers identical electrical and thermal performance but improves manufacturing throughput via tape-and-reel delivery, while the R5F101GCANA#20 removes data flash to lower unit cost and simplify certification for fixed-function deployments.

How much data flash memory does the R5F100GCANA#20 provide, and what is its endurance?
The R5F100GCANA#20 provides 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. It supports background operation (BGO), allowing CPU code execution from program memory during data flash rewrites - essential for reliable over-the-air firmware updates.
What package type and pin count does the R5F100GCANA#20 use?
The R5F100GCANA#20 uses a 24-pin HWQFN package (4 mm × 4 mm, 0.5 mm pitch), identified by the 'NA' in the part number and confirmed in Table 1-1 of the RL78/G13 datasheet. This compact, thermally efficient package supports reflow soldering and is MSL Level 3 compliant.
Can the R5F100GCANA#20 operate from a single 1.8 V supply?
Yes, the R5F100GCANA#20 supports single-supply operation from 1.6 V to 5.5 V - including 1.8 V - across its full industrial temperature range.
