Product details
Overview
R5F101GAANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, 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), 10-bit ADC (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101GAANA#U0 datasheet, R5F101GAANA#U0 pinout, R5F101GAANA#U0 application, or R5F101GAANA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (A-grade), and support for LIN-bus UART, CSI, and I²C peripherals in space-constrained embedded control designs.
Technical Context
The R5F101GAANA#U0 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), and 1 MB address space. It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, 2–8-channel CSI, 2–4-channel DMA, and 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all configurable under single-supply operation from 1.6 V.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GAANA#U0?
The R5F101GAANA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard test conditions per Renesas R01DS0131EJ0380. The R5F101GAANA#U0 achieves this without external clock sources thanks to its integrated high-accuracy oscillator.
Does the R5F101GAANA#U0 include on-chip data flash memory?
No, the R5F101GAANA#U0 does not include on-chip data flash memory. Its part number encoding ('101' prefix) explicitly indicates data flash omission, distinguishing it from '100'-series variants like R5F100GAANA#U0 which integrate 4 KB data flash. The R5F101GAANA#U0 relies on code flash for firmware and external non-volatile memory for parameter storage.
What package type and thermal characteristics apply to the R5F101GAANA#U0?
The R5F101GAANA#U0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad (Renesas code PWQN0048KB-A). This package supports efficient heat dissipation in compact enclosures; the thermal pad must be soldered to a PCB copper pour tied to VSS for optimal junction temperature control per datasheet layout guidelines.
Which serial communication interfaces are supported by the R5F101GAANA#U0?
The R5F101GAANA#U0 supports three primary serial interfaces: CSI (Simplified SPI) with 2–8 channels, UART/LIN with 2–4 channels (including LIN 2.1/2.2 compliance), and I²C/Simplified I²C with 3–10 channels. All are independently configurable and share no fixed pin conflicts - enabling concurrent use in multi-peripheral systems such as sensor hubs or motor drives.
What is the operating temperature range specified for the R5F101GAANA#U0?
The R5F101GAANA#U0 is rated for an operating ambient temperature range of –40°C to +85°C, conforming to the 'A' grade designation in its part number. This qualifies it for industrial and consumer applications but excludes extended-temperature industrial ('G' grade, –40°C to +105°C) use cases - verify thermal derating in high-ambient environments per R01DS0131EJ0380 Section 18.3.
