Product details
Overview
R5F101BAANA#U0 from Renesas is a 32-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across –40°C to +85°C. It delivers 41 DMIPS at 32 MHz, integrates an RTC, 10-bit ADC (6 channels), UART/SPI/I²C interfaces, and ultra-low-power HALT/STOP modes (0.57 μA RTC+LVD).
For engineers reviewing the R5F101BAANA#U0 datasheet, R5F101BAANA#U0 pinout, R5F101BAANA#U0 application, or R5F101BAANA#U0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.5 mm pitch) footprint, absence of on-chip data flash, industrial-grade temperature range, and support for low-power sensor node and appliance control designs.
Technical Context
The R5F101BAANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features a 1 MB address space and four banks of 8-bit general-purpose registers.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, HALT/STOP/SNOOZE low-power modes, and a dedicated low-speed on-chip oscillator for watchdog operation. Peripheral integration covers up to 16-channel 16-bit timers, real-time clock with calendar/alarm, and background operation-capable data flash programming logic (though this variant omits data flash).

FAQ
What is the maximum operating frequency and performance of the R5F101BAANA#U0?
The R5F101BAANA#U0 operates at up to 32 MHz and delivers 41 DMIPS. Its RL78 CPU core uses a 3-stage pipeline and supports variable instruction execution times-from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed RTC mode-enabling precise trade-offs between throughput and power consumption in the R5F101BAANA#U0.
Does the R5F101BAANA#U0 include on-chip data flash memory?
No, the R5F101BAANA#U0 contains 16 KB of code flash and 2 KB of RAM but zero data flash memory. This distinguishes it from the R5F100xx series (e.g., R5F100BAANA#U0), which includes 4 KB data flash. The R5F101BAANA#U0 is optimized for applications where firmware-only storage suffices.
What package type and pin count does the R5F101BAANA#U0 use?
The R5F101BAANA#U0 uses a 32-pin HWQFN package (5 × 5 mm, 0.5 mm pitch) with an exposed thermal pad. This surface-mount package supports high-density PCB layouts and efficient heat dissipation, and is documented in Renesas' PWQN0032KB-A and PWQN0032KE-A packaging specifications for the R5F101BAANA#U0.
What low-power modes are supported by the R5F101BAANA#U0, and what are their typical current draws?
The R5F101BAANA#U0 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, it maintains real-time clock operation and voltage monitoring while drawing less than 1 μA-critical for battery-powered applications. These values are measured per Renesas R01DS0131EJ0380 datasheet for the R5F101BAANA#U0.
Which communication interfaces are integrated into the R5F101BAANA#U0?
The R5F101BAANA#U0 integrates UART (2 channels), CSI (SPI-compatible serial interface, 2 channels), and I²C (3 channels). These interfaces support common industrial and consumer protocols-including LIN via UART-and allow concurrent peripheral connectivity without external bus expanders in the R5F101BAANA#U0.
