Product details
Overview
R5F101GAANA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz. It integrates a real-time clock, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered industrial sensing nodes.
For engineers reviewing the R5F101GAANA#W0 datasheet, R5F101GAANA#W0 pinout, R5F101GAANA#W0 application, or R5F101GAANA#W0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm pitch package, absence of on-chip data flash (confirmed by "101" suffix), -40°C to +85°C industrial temperature grade ('A' suffix), and support for SNOOZE/STOP/HALT low-power states in resource-constrained embedded control designs.
Technical Context
The R5F101GAANA#W0 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). Its memory map spans 1 MB address space, with dedicated 128 KB code flash organized in 1 KB blocks and hardware security features including block erase prohibition.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, and a 10-bit A/D converter with internal 1.45 V reference and temperature sensor. Serial connectivity comprises up to 8 CSI (SPI-compatible), 4 UART/LIN, and 10 I²C channels - all configurable per pin function mapping in the 48-pin HWQFN layout.

The R5F101GAANA#W0 features an RL78 16-bit CISC core with a maximum operating frequency of 32 MHz. It achieves 41 DMIPS performance at this speed using a 3-stage pipeline architecture, and supports variable instruction execution times from 0.03125 μs (high-speed mode) to 30.5 μs (subsystem clock mode), enabling flexible trade-offs between performance and power consumption in the R5F101GAANA#W0.
Does the R5F101GAANA#W0 include on-chip data flash memory?
No, the R5F101GAANA#W0 does not include on-chip data flash memory. The "101" in the part number explicitly denotes absence of data flash, distinguishing it from "100"-series variants like R5F100GAANA#W0 which integrate 8 KB data flash. Applications requiring nonvolatile parameter storage must use external EEPROM, FRAM, or utilize code flash sectors with wear-leveling software in the R5F101GAANA#W0.
What package type and pin count does the R5F101GAANA#W0 use?
The R5F101GAANA#W0 uses a 48-pin HWQFN (Heat Sink Quad Flat No-lead) package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package is supplied in embossed tape (#W0 suffix) and is RoHS-compliant, offering high I/O density, excellent thermal performance, and suitability for automated SMT assembly in space-constrained industrial and consumer products using the R5F101GAANA#W0.
What are the supported low-power modes and their typical current consumption for the R5F101GAANA#W0?
The R5F101GAANA#W0 supports HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode (intermediate power state enabling peripheral operation during CPU sleep). These modes are hardware-controlled and retain RAM content, allowing rapid wake-up for event-driven applications such as sensor polling or button interrupts in battery-powered systems built around the R5F101GAANA#W0.
Which serial communication interfaces are available on the R5F101GAANA#W0?
The R5F101GAANA#W0 provides up to 8 CSI (SPI-compatible) channels, 4 UART/LIN channels (with hardware LIN bus support), and up to 10 I²C channels. All interfaces are multiplexed across GPIO pins and configurable via register settings, enabling concurrent use of SPI for sensor acquisition, UART for debugging or host communication, and I²C for EEPROM or PMIC control in designs based on the R5F101GAANA#W0.
