Product details
Overview
R5F101GAANA#40 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active current, and supports ultra-low-power STOP mode (0.57 μA) with RTC and LVD - ideal for battery-powered industrial sensors and motor control modules.
For engineers reviewing the R5F101GAANA#40 datasheet, R5F101GAANA#40 pinout, R5F101GAANA#40 application, or R5F101GAANA#40 equivalent, key selection criteria include its 40-pin HWQFN (6 × 6 mm, 0.5-mm pitch) package, absence of on-chip data flash, -40°C to +105°C temperature rating (G-grade), and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI interfaces.
Technical Context
The R5F101GAANA#40 implements the RL78 CPU core with a 3-stage CISC 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). Its memory map spans 1 MB address space, with 128 KB code flash organized in 1-KB blocks and 12 KB on-chip RAM.
Power management includes on-chip POR, 14-level LVD with interrupt/reset options, HALT/STOP/SNOOZE low-power modes, and a dedicated low-speed on-chip oscillator for watchdog timer operation. Peripheral integration covers DMA (4 channels), multiplier/divider/MAC units, real-time clock with calendar/alarm, and 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GAANA#20 | Identical core, flash, RAM, and peripherals; differs only in packaging - 20-pin HWQFN instead of 40-pin | Targeted for space-constrained designs with fewer I/O and analog channel requirements | Select #20 when ≤20 pins suffice and board area is critical; not pin-compatible with #40 |
| R5F100GAANA#40 | Same package and pinout, but includes 8 KB data flash and lacks G-grade (-40°C to +105°C) qualification (A/D-grade only) | Suitable for consumer or commercial applications requiring background data flash writes | Choose #40 if data flash persistence is essential and ambient temperature stays ≤+85°C |
Compared with R5F101GAANA#20 and R5F100GAANA#40, the R5F101GAANA#40 uniquely combines industrial temperature range, 40-pin I/O flexibility, and absence of data flash - optimizing cost and reliability for fixed-function control where field data logging is unnecessary.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101GAANA#40?
The R5F101GAANA#40 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. The RL78 CPU core's 3-stage pipeline ensures deterministic execution timing critical for real-time control loops in the R5F101GAANA#40.
Does the R5F101GAANA#40 include on-chip data flash memory?
No, the R5F101GAANA#40 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas documentation, this variant provides 128 KB of code flash only. In contrast, "100"-series parts (e.g., R5F100GAANA#40) integrate 8 KB of data flash. The R5F101GAANA#40 relies on external non-volatile storage or SRAM backup for configuration retention.
What package type and pin count does the R5F101GAANA#40 use?
The R5F101GAANA#40 uses a 40-pin HWQFN package measuring 6 × 6 mm with 0.5-mm pitch and an exposed thermal pad. This is confirmed by Table 1-1 in the RL78/G13 datasheet (R01DS0131EJ0380), where "E" denotes 40-pin count and "NA" denotes HWQFN package type - matching the suffix "ANA" in the part number. The #40 tape-and-reel packaging specification further confirms this physical form factor.
What is the operating temperature range specified for the R5F101GAANA#40?
The R5F101GAANA#40 is rated for industrial operation from -40°C to +105°C, denoted by the "G" grade in its part number. This distinguishes it from "A"-grade (-40°C to +85°C) and "D"-grade (-40°C to +85°C, industrial) variants. The extended high-temperature capability makes the R5F101GAANA#40 suitable for under-hood automotive subsystems, industrial motor drives, and enclosed power electronics where ambient heat buildup occurs.
Which communication interfaces are integrated into the R5F101GAANA#40?
The R5F101GAANA#40 integrates multiple serial interfaces: CSI (SPI-compatible) with 2–8 channels, UART/LIN with 2–4 channels, and I²C/Simplified I²C with 3–10 channels. These are physically mapped to multi-function pins like P10 (SCK00/SCL00), P11 (SI00/RxD0/SDA00), and P12 (SO00/TxD0), enabling concurrent use of UART for debugging, I²C for sensor reads, and CSI for display or memory interfacing - all within the R5F101GAANA#40's single-chip solution.
