Product details
Overview
R5F100BAANA#U0 from Renesas is a 32-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (6 channels), RTC, and UART/I²C/CSI interfaces - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F100BAANA#U0 datasheet, R5F100BAANA#U0 pinout, R5F100BAANA#U0 application, or R5F100BAANA#U0 equivalent, key selection criteria include its 32-pin HWQFN-0.5mm package, 16 KB code flash + 4 KB data flash allocation, 10-bit ADC input count, real-time clock calendar support, and low-voltage operation down to 1.6 V for energy-constrained embedded designs.
Technical Context
The R5F100BAANA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and background operation (BGO) for data flash rewriting while executing program code.
It delivers 66 μA/MHz active current consumption and supports multiple low-power states: HALT (CPU stop, peripherals active), STOP (all clocks halted except RTC/LVD), and SNOOZE (selective peripheral wake-up). The device includes 2-channel DMA, 16-bit timer (8 channels), 12-bit interval timer, watchdog timer, and simplified I²C/UART/CSI serial interfaces.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100BAANA#U0?
The R5F100BAANA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency under standard benchmark conditions, enabling responsive real-time control in applications such as motor commutation and sensor fusion without external acceleration.
Does the R5F100BAANA#U0 include integrated data flash memory, and what is its endurance specification?
Yes, the R5F100BAANA#U0 includes 4 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. This enables reliable parameter storage, calibration data retention, and firmware update staging without external EEPROM or FRAM components.
What low-power modes does the R5F100BAANA#U0 support, and what is its lowest active current consumption?
The R5F100BAANA#U0 supports HALT, STOP, and SNOOZE modes. Its lowest active current is 66 μA per MHz at 32 MHz; in STOP mode with only RTC and LVD enabled, it draws just 0.57 μA - making it suitable for decade-long deployments in coin-cell-powered IoT endpoints.
Can the R5F100BAANA#U0 operate from a 1.8 V supply, and what is its full valid voltage range?
Yes, the R5F100BAANA#U0 operates across a wide 1.6 V to 5.5 V single-supply range. At 1.8 V, all peripherals including the 10-bit ADC, RTC, and UART remain fully functional - supporting direct interfacing with LiFePO₄ batteries or energy-harvesting sources without regulation overhead.
How many analog input channels does the R5F100BAANA#U0 provide, and what resolution and reference options are available?
The R5F100BAANA#U0 provides six 10-bit analog input channels (ANI0–ANI5) with selectable internal 1.45 V reference or external AVREFP/AVREFM inputs. This configuration supports precision sensor interfacing - such as thermistors or bridge transducers - with consistent linearity and noise immunity across its operating voltage range.
