Product details
Overview
R5F101BAANA#40 from Renesas is a 32-bit RL78/G13 microcontroller with 16 KB flash memory, 2 KB RAM, and no data flash, housed in a 40-pin HWQFN (6 × 6 mm, 0.5-mm pitch) package. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT for battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F101BAANA#40 datasheet, R5F101BAANA#40 pinout, R5F101BAANA#40 application, or R5F101BAANA#40 equivalent, key selection criteria include its 40-pin HWQFN footprint, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (A-suffix), and integrated 10-bit ADC with up to 26 channels - critical for analog-sensing edge devices requiring compact, low-power MCU solutions.
Technical Context
The R5F101BAANA#40 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz RTC mode). Its memory map spans 1 MB address space, with dedicated SFR regions supporting peripheral control via bit-manipulation instructions.
Power management includes an on-chip POR circuit, 14-level LVD with interrupt/reset capability, and multiple low-power states (HALT, STOP, SNOOZE) coordinated with the subsystem clock and high-speed on-chip oscillator (selectable from 1–32 MHz ±1.0%). DMA controller supports 2-channel transfers with 2-clock latency between SFR and internal RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BAANA#40 | Includes 4 KB data flash and background operation (BGO); same pinout, package, and peripherals | Required where firmware must log sensor data or perform field updates without halting execution | Select when nonvolatile parameter storage or safe firmware updates are mandatory |
| R5F101BAANA#20 | Identical core and memory specs but in 20-pin LSSOP package; fewer GPIOs and analog channels | Suitable for space-constrained, lower-peripheral-count designs like simple timers or basic remotes | Choose only if PCB layout requires smaller footprint and I/O count reduction is acceptable |
Compared with R5F101BAANA#40, R5F100BAANA#40 adds data flash for runtime logging but increases cost and code complexity; R5F101BAANA#20 reduces I/O count by >50% and removes analog channel flexibility - both trade-offs require explicit validation against system signal routing and data persistence requirements.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101BAANA#40?
The R5F101BAANA#40 operates at up to 32 MHz and achieves 41 DMIPS performance per the RL78/G13 datasheet. This metric reflects integer computational throughput under standard benchmark conditions and supports real-time tasks such as sensor fusion, motor commutation, and protocol stack processing without external acceleration.
Does the R5F101BAANA#40 include on-chip data flash memory?
No, the R5F101BAANA#40 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number (per Renesas RL78/G13 naming convention), this variant provides only 16 KB of code flash and 2 KB of RAM. Data storage must be implemented externally or via EEPROM emulation in code flash using the provided flash library.
What package type and pin count does the R5F101BAANA#40 use?
The R5F101BAANA#40 uses a 40-pin HWQFN package measuring 6 × 6 mm with 0.5-mm pitch and an exposed thermal pad. This package is designated by the "NA" suffix and "#40" tape-and-reel packaging code, and is compatible with standard reflow profiles for high-volume SMT assembly.
What is the operating temperature range specified for the R5F101BAANA#40?
The R5F101BAANA#40 is rated for an operating ambient temperature range of -40°C to +85°C, corresponding to the "A" grade in Renesas' RL78/G13 qualification. This makes it suitable for consumer electronics and industrial equipment deployed in uncontrolled indoor environments, but not for under-hood automotive or extended-temperature industrial applications.
Which communication interfaces are supported by the R5F101BAANA#40?
The R5F101BAANA#40 supports up to 2 CSI (SPI-compatible) channels, 2 UART/LIN channels, and up to 3 I²C/Simplified I²C channels. All serial interfaces support peripheral channel select (CS) for flexible pin mapping, and UART includes LIN bus physical layer compliance for automotive body electronics integration.
