FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104AADSP#50?
The R5F104AADSP#50 operates at up to 32 MHz and delivers 44 DMIPS (Dhrystone MIPS) at that speed. This performance level is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling real-time execution of control algorithms, communication stacks, and sensor processing within its 32 KB flash and 4 KB RAM resources.
Does the R5F104AADSP#50 support in-system programming and secure firmware updates?
Yes, the R5F104AADSP#50 supports in-system programming via its on-chip debug interface and includes flash shield window protection, boot swapping, and block-level erase/write prohibition. These features enable secure, field-upgradable firmware deployment - critical for industrial devices requiring remote maintenance and anti-tampering safeguards throughout their operational lifecycle.
What analog peripherals are integrated into the R5F104AADSP#50?
The R5F104AADSP#50 integrates a 10-bit ADC with up to 20 input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. It also includes an 8-bit DAC (two channels), two comparators, and dedicated AVREFP/AVREFM pins for high-accuracy ratiometric measurements - eliminating the need for external references or signal-conditioning ICs in most sensor interface designs.
Is the R5F104AADSP#50 pin-compatible with other RL78/G14 variants in the 30-pin LSSOP package?
Yes, all RL78/G14 devices in the 30-pin LSSOP package - including R5F104AAxSP, R5F104ACxSP, R5F104ADxSP, and R5F104AExSP - share identical pinout, electrical characteristics, and peripheral mapping. This allows direct substitution during design-in or production ramp based on flash/RAM requirements without PCB layout changes.
What power-saving modes does the R5F104AADSP#50 support, and what are their typical current draws?
The R5F104AADSP#50 supports HALT, STOP, and SNOOZE modes. In HALT mode, current draw is 66 μA/MHz; in STOP mode with only RTC and LVD active, it drops to 0.60 μA. SNOOZE mode allows selected peripherals (e.g., UART, ADC) to operate while CPU remains halted - ideal for low-duty-cycle sensor polling with sub-10 μA average current in battery-powered applications.
