Product details
Overview
R5F101BDANA#00 from Renesas is a 32-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 32 KB flash, 2 KB RAM, and no data flash memory, designed for ultra-low-power industrial applications operating from −40°C to +85°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active current and 0.57 μA in RTC+LVD-only mode, and integrates 16-bit timers, 10-bit ADC (12 channels), UART, I²C, and CSI interfaces.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101BDANA#00?
The R5F101BDANA#00 operates up to 32 MHz with the high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under these conditions, enabling deterministic real-time response for control algorithms and communication stacks in the R5F101BDANA#00.
Does the R5F101BDANA#00 include data flash memory?
No, the R5F101BDANA#00 does not include data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash, distinguishing it from "100"-series variants like R5F100BDANA#00 which integrate 4 KB of data flash. This makes the R5F101BDANA#00 ideal for applications where only code storage is required.
What package type and pin count does the R5F101BDANA#00 use?
The R5F101BDANA#00 uses a 32-pin HWQFN package (5 × 5 mm, 0.5 mm pitch) with an exposed thermal pad. This compact, surface-mount package supports high-density PCB layouts and efficient thermal management, and is explicitly listed in Table 1-1 of the RL78/G13 datasheet for the R5F101BDANA#00 ordering code.
Which low-power modes are supported by the R5F101BDANA#00, and what is its lowest current consumption?
The R5F101BDANA#00 supports HALT, STOP, and SNOOZE modes. In HALT mode with only RTC and LVD active, it draws just 0.57 μA - verified in the datasheet's electrical characteristics table. This ultra-low quiescent current enables multi-year operation in battery-backed applications using the R5F101BDANA#00.
How many analog input channels and what ADC resolution does the R5F101BDANA#00 provide?
The R5F101BDANA#00 integrates a 10-bit successive-approximation ADC with 12 analog input channels (ANI0–ANI11), plus internal reference voltage (1.45 V) and temperature sensor. This configuration is confirmed for the 32-pin HWQFN variant and supports simultaneous sampling for multi-sensor industrial monitoring in the R5F101BDANA#00.
