Product details
Overview
R5F101BDANA#40 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash, 32 KB code flash, 2 KB RAM, and 32-pin HWQFN (5 × 5 mm, 0.5-mm pitch) package, 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 RTC, 10-bit ADC (up to 26 channels), UART/SPI/I²C interfaces, and ultra-low-power modes including STOP (0.57 μA) for battery-powered sensor nodes and industrial control peripherals.
For engineers reviewing the R5F101BDANA#40 datasheet, R5F101BDANA#40 pinout, R5F101BDANA#40 application, or R5F101BDANA#40 equivalent, key selection criteria include its data-flash-free configuration, industrial-grade temperature support, 32-pin HWQFN footprint, real-time clock with calendar, and integrated low-voltage detector with 14-level interrupt/reset options.
Technical Context
The R5F101BDANA#40 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). Its memory map spans 1 MB address space, with on-chip resources including 32 KB flash (1 KB block size), 2 KB RAM, and dedicated peripherals such as 16-bit timers (12 channels), 12-bit interval timer, and watchdog timer.
Power management includes HALT, STOP, and SNOOZE modes, with POR and LVD circuits enabling robust reset behavior across voltage transients. The MCU supports background operation during data flash rewriting (BGO not applicable here due to absence of data flash), and features DMA controller (2 channels), multiplier/divider/MAC unit, and simplified SPI/UART/I²C serial interfaces - all optimized for deterministic real-time response in resource-constrained embedded systems.

FAQ
What is the flash memory configuration of the R5F101BDANA#40?
The R5F101BDANA#40 contains 32 KB of on-chip code flash memory organized in 1 KB erasable blocks, with no data flash memory. This configuration is optimized for applications where firmware storage is the sole non-volatile requirement - eliminating data flash overhead while retaining self-programming capability via boot swap and flash shield window functions. The R5F101BDANA#40 shares the same flash architecture and programming interface as other RL78/G13 devices.
Does the R5F101BDANA#40 support real-time clock functionality?
Yes, the R5F101BDANA#40 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm interrupt generation, and hardware clock correction. It operates independently in STOP mode with only 0.57 μA current draw, using either an external 32.768 kHz crystal or the internal low-speed oscillator. This RTC is fully accessible via dedicated registers and requires no external timekeeping components - a key advantage for battery-backed timestamping in the R5F101BDANA#40.
What are the low-power operation modes supported by the R5F101BDANA#40?
The R5F101BDANA#40 supports HALT, STOP, and SNOOZE modes. STOP mode achieves 0.57 μA with RTC and LVD active; HALT mode draws 66 μA/MHz; SNOOZE enables selective peripheral operation during low-power sleep. All modes retain RAM content and allow wake-up via external interrupt, RTC alarm, or comparator event. These capabilities make the R5F101BDANA#40 especially effective in energy-harvesting and battery-operated systems where duty-cycled operation is essential.
Which serial communication interfaces are available on the R5F101BDANA#40?
The R5F101BDANA#40 provides up to 4 UART channels (with LIN-bus support), 8 CSI/SPI channels, and 10 I²C/Simplified I²C channels - configurable across its multi-function pins. These interfaces operate concurrently and support independent clock sources, enabling simultaneous communication with displays, sensors, EEPROMs, and industrial buses. The R5F101BDANA#40's flexible pin mapping allows designers to allocate serial resources without compromising GPIO count or analog input availability.
Is the R5F101BDANA#40 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F101BDANA#40 is pin-compatible with all 32-pin HWQFN RL78/G13 devices sharing the same NA suffix (e.g., R5F100BDANA#40, R5F101ADANA#40), including identical power, reset, clock, and I/O pin assignments. This allows direct substitution within the same footprint for memory or feature scaling - for example, upgrading to data flash (R5F100BDANA#40) or downgrading flash size (R5F101ADANA#40) without PCB revision. The R5F101BDANA#40 maintains full functional and mechanical compatibility across this family subset.
