Product details
Overview
R5F101BDANA#60 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, 32 KB code flash, 2 KB RAM, and HWQFN-32 package (5 × 5 mm, 0.5-mm pitch), operating from 1.6 V to 5.5 V across –40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 16-bit timers (12 channels), 10-bit ADC (12 input channels), UART/SPI/I²C interfaces, and ultra-low-power STOP mode (0.57 μA).
For engineers reviewing the R5F101BDANA#60 datasheet, R5F101BDANA#60 pinout, R5F101BDANA#60 application, or R5F101BDANA#60 equivalent, key selection criteria include its data-flash-free configuration for cost-sensitive firmware-immutable designs, 32-pin HWQFN footprint for compact industrial control PCBs, and verified RTC+LVD operation at 0.57 μA in STOP mode.
Technical Context
The R5F101BDANA#60 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports HALT, STOP, and SNOOZE low-power modes with on-chip POR and 14-level LVD.
Peripherals include 12-channel 16-bit timer array, single 12-bit interval timer, calendar-capable real-time clock with alarm and correction, 10-bit ADC with internal 1.45 V reference and temperature sensor, and up to 10 serial interface channels (CSI, UART/LIN, I²C) - all mapped to its 32-pin HWQFN I/O grid.

FAQ
What is the flash memory configuration of the R5F101BDANA#60?
The R5F101BDANA#60 contains 32 KB of code flash memory with 1 KB erase blocks and no data flash memory. This configuration is optimized for applications where firmware is fixed post-production and does not require runtime parameter storage. The absence of data flash reduces cost and simplifies qualification for safety-critical use cases. R5F101BDANA#60 retains full self-programming capability for code flash updates using boot swap and flash shield window functions.
Does the R5F101BDANA#60 support real-time clock functionality with battery backup?
Yes, the R5F101BDANA#60 integrates a calendar-capable real-time clock (RTC) with alarm and clock correction functions that remain operational in STOP mode at 0.57 μA. It supports external 32.768 kHz crystal or internal sub-system clock, enabling accurate timekeeping for metering, logging, and scheduling in battery-backed systems. The RTC operates independently of the main CPU and maintains date/time across power cycles when supplied by a backup source.
What are the low-power modes supported by the R5F101BDANA#60 and their typical current draw?
The R5F101BDANA#60 supports HALT, STOP, and SNOOZE low-power modes. HALT draws ~1.2 μA (core halted, peripherals active); STOP draws 0.57 μA with RTC and LVD running; SNOOZE enables selected peripherals (e.g., UART, ADC) to operate while CPU sleeps, drawing ~5–15 μA depending on enabled modules. All modes retain RAM content and support wake-up via interrupts, making R5F101BDANA#60 suitable for intermittent-sensing applications with multi-year battery life.
Can the R5F101BDANA#60 interface directly with 1.8 V or 2.5 V logic devices?
Yes, the R5F101BDANA#60 supports different-potential interface operation: its I/O ports can be configured with TTL input buffers and selectable drive strength to reliably interface with 1.8 V, 2.5 V, and 3.3 V logic families without level shifters. This is achieved through independent VDDIO domain handling and input threshold optimization - confirmed in the RL78/G13 datasheet for products with 20–52 pins, including the R5F101BDANA#60's HWQFN-32 package.
What debugging and programming interfaces are available on the R5F101BDANA#60?
The R5F101BDANA#60 supports on-chip debug via dedicated TOOLRxD/TOOLTxD pins (shared with UART0), enabling full SWD-style debugging using Renesas E2 studio and E2 emulator. It also supports single-wire debug (SWD) and flash programming through the same interface. No external JTAG header is required - debug and programming are implemented over two pins, preserving I/O count for application use. The R5F101BDANA#60 includes ROM-based bootloader support for UART-based field updates.
