Product details
Overview
R5F101BDANA#U0 from Renesas is a 32-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash, designed for ultra-low-power industrial applications operating from −40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features a 10-bit A/D converter with up to 26 channels, real-time clock with calendar function, and supports UART, I²C, and CSI serial interfaces.
For engineers reviewing the R5F101BDANA#U0 datasheet, R5F101BDANA#U0 pinout, R5F101BDANA#U0 application, or R5F101BDANA#U0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.5-mm pitch) package, absence of on-chip data flash, industrial temperature grade (−40°C to +85°C), and support for SNOOZE mode operation with background data flash programming capability in compatible variants.
Technical Context
The R5F101BDANA#U0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (up to 16 channels), and a real-time clock with alarm and calendar functions.
Power management includes HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.57 μA in RTC+LVD-only operation. The device uses a single 1.6–5.5 V supply, incorporates an on-chip voltage detector with 14 selectable LVD levels, and supports DMA transfers with 2-channel capability and 2-clock latency for 8/16-bit SFR ↔ RAM operations.

FAQ
What is the maximum operating frequency and performance of the R5F101BDANA#U0?
The R5F101BDANA#U0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction timing - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed 32.768 kHz mode - enabling precise trade-offs between throughput and power consumption in the R5F101BDANA#U0.
Does the R5F101BDANA#U0 include on-chip data flash memory?
No, the R5F101BDANA#U0 does not include on-chip data flash memory. Per the RL78/G13 family designation, the "101" prefix indicates zero data flash capacity. This variant provides 32 KB of code flash and 2 KB of RAM only. For data logging or parameter storage, external EEPROM or FRAM must be used, or consider the R5F100BDANA#U0 which includes 4 KB of data flash.
What package type and pin count does the R5F101BDANA#U0 use?
The R5F101BDANA#U0 uses a 32-pin HWQFN package (5 × 5 mm, 0.5-mm pitch), identified by the "NA" suffix in the part number and "#U0" tray packaging code. This thermally enhanced, lead-free package supports reflow soldering and is rated for industrial temperature operation (−40°C to +85°C), making it suitable for space-constrained, high-reliability applications.
Which serial communication interfaces are supported by the R5F101BDANA#U0?
The R5F101BDANA#U0 supports three serial interface types: CSI (SPI-compatible, up to 8 channels), UART/LIN (up to 4 channels), and I²C/Simplified I²C (up to 10 channels). These are implemented via multiplexed GPIO pins (e.g., P10–P17), allowing flexible peripheral assignment. No dedicated hardware LIN transceiver is integrated - external transceiver required for LIN physical layer compliance in R5F101BDANA#U0 designs.
How does the R5F101BDANA#U0 handle low-power operation in battery-powered systems?
The R5F101BDANA#U0 offers three key low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE (peripheral-triggered wake-up with CPU halted). Its 1.6–5.5 V supply range and internal voltage detector with 14 LVD levels allow precise brown-out detection and graceful shutdown - critical for maintaining data integrity and extending battery life in remote R5F101BDANA#U0 deployments.
