FAQ
What is the maximum operating frequency and performance rating of the R5F104BGAFP#V0?
The R5F104BGAFP#V0 operates at up to 32 MHz with a measured performance of 44 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and optimized instruction set, including hardware multiply/divide. The high-speed on-chip oscillator supports ±1.0% accuracy across 1.8–5.5 V and -40 to +85°C, eliminating need for external crystals in many timing-critical applications. This makes the R5F104BGAFP#V0 suitable for real-time control loops requiring deterministic execution.
Does the R5F104BGAFP#V0 support in-system programming and secure firmware updates?
Yes, the R5F104BGAFP#V0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features to prevent unauthorized reprogramming. Self-programming with boot swap functionality allows safe firmware updates by maintaining a backup copy during write operations. Data flash supports background operation (BGO), enabling the R5F104BGAFP#V0 to execute application code while rewriting non-volatile storage - critical for secure OTA updates in deployed devices.
How many analog-to-digital converter (ADC) channels does the R5F104BGAFP#V0 provide, and what are their key specifications?
The R5F104BGAFP#V0 integrates a 10-bit successive-approximation ADC with up to 20 input channels, operating across the full 1.6–5.5 V supply range. It includes an internal 1.45 V reference voltage and on-die temperature sensor, enabling accurate voltage, current, and thermal measurements without external components. Conversion time is programmable down to 1.1 μs per sample, and the ADC supports hardware-triggered sampling via ELC - allowing precise synchronization with PWM or timer events in motor control applications using the R5F104BGAFP#V0.
What low-power modes are available on the R5F104BGAFP#V0, and what are their typical current draws?
The R5F104BGAFP#V0 offers HALT (66 μA/MHz), STOP (0.60 μA), and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.60 μA - ideal for battery-backed real-time clocks and alarm wake-up functions. SNOOZE mode permits selected peripherals (e.g., ADC, UART) to operate autonomously while CPU remains halted, reducing average power in sensor polling applications. All modes retain RAM contents and support fast wake-up (< 4.4 μs from HALT), making the R5F104BGAFP#V0 well-suited for energy-constrained industrial nodes.
Is the R5F104BGAFP#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 44-pin LQFP-0.8 mm package (e.g., R5F104AGAFP#V0, R5F104CGAFP#V0, R5F104DGAFP#V0) share identical pinouts and electrical characteristics. This allows direct substitution within the same memory/peripheral configuration tier - for example, upgrading from R5F104BGAFP#V0 (96 KB flash) to R5F104CGAFP#V0 (128 KB flash) requires no PCB change. However, firmware must be validated for memory map and peripheral enable differences before deployment of the R5F104BGAFP#V0 replacement.
