Product details
Overview
R5F104BDAFP#10 from Renesas is a 32-pin LQFP-packaged RL78/G14 16-bit microcontroller with 48 KB flash, 4 KB data flash, and 4 KB RAM, operating at 1.6–5.5 V and delivering 44 DMIPS at 32 MHz. It integrates an ultra-low-power CPU core (66 μA/MHz active, 0.60 μA RTC+LVD), 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control in industrial sensor nodes and power-constrained HMI systems.
For engineers reviewing the R5F104BDAFP#10 datasheet, R5F104BDAFP#10 pinout, R5F104BDAFP#10 application, or R5F104BDAFP#10 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm pitch package, industrial-grade temperature range (−40 to +85°C), integrated data flash rewrite capability (1M cycles), and support for SNOOZE mode for low-latency peripheral wake-up without full CPU restart.
Technical Context
The R5F104BDAFP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz to 30.5 µs @ 32.768 kHz). It features Event Link Controller (ELC) for hardware-triggered peripheral chaining and Data Transfer Controller (DTC) supporting block/chain transfers activated by 19–26 event sources.
Its memory subsystem includes 48 KB on-chip code flash (1 KB blocks, security-lockable), 4 KB data flash with background operation (BGO), and 4 KB RAM. Power management includes HALT/STOP/SNOOZE modes, on-chip POR/LVD, and selectable oscillator options (1–64 MHz high-accuracy on-chip RC).

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104BDAFP#10?
The R5F104BDAFP#10 operates at up to 32 MHz, achieving 44 DMIPS (Dhrystone MIPS) performance. Its RL78 CPU core executes instructions in as little as 0.03125 µs at this speed, enabling deterministic real-time control in applications such as motor commutation and closed-loop feedback systems. The high-accuracy on-chip oscillator (±1.0% over −20 to +85°C) eliminates need for external crystal in many cases.
Does the R5F104BDAFP#10 support in-system programming and secure firmware updates?
Yes, the R5F104BDAFP#10 supports full in-system programming via its on-chip debug interface and includes flash shield window protection to prevent unauthorized access to code memory. It enables boot swapping and self-programming of both code and data flash - allowing safe firmware updates in the field without requiring external programmers or erasing the entire flash array.
How does the SNOOZE mode in the R5F104BDAFP#10 differ from HALT or STOP modes?
SNOOZE mode allows selected peripherals (e.g., ADC, RTC, serial interfaces) to remain active and generate interrupts while the CPU core is halted - enabling ultra-low-power periodic operations with sub-microsecond wake-up latency. Unlike HALT (CPU stopped, peripherals active) or STOP (all clocks halted except sub-system clock), SNOOZE maintains precise timing for autonomous peripheral sequences without CPU involvement.
What are the key differences between the R5F104BDAFP#10 and the R5F104BEAFP#10?
The R5F104BDAFP#10 has 48 KB flash and 4 KB RAM, while the R5F104BEAFP#10 offers 64 KB flash and 5.5 KB RAM - both in identical 32-pin LQFP packages with matching pinouts and peripheral sets. The R5F104BEAFP#10 is suited for applications needing larger firmware images or additional RAM for complex protocols, whereas the R5F104BDAFP#10 provides optimal balance for mid-complexity industrial firmware.
Can the R5F104BDAFP#10 drive standard 5 V logic peripherals directly?
Yes - the R5F104BDAFP#10 supports different-potential interface operation, allowing selected I/O pins to tolerate 5 V inputs and drive 5 V-tolerant loads when powered from 5 V VDD. Its N-ch open-drain I/Os (with 6 V withstand voltage) and configurable pull-ups enable direct connection to 5 V UART transceivers, relays, or LED drivers without external level-shifting circuitry.
