Product details
Overview
R5F104LEAFP#10 from Renesas is a 48-pin LQFP-48, 48 KB flash, 5.5 KB RAM RL78/G14 16-bit microcontroller with ultra-low power consumption (66 μA/MHz), 32 MHz max CPU speed, 10-bit ADC (16 channels), and integrated RTC, LVD, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104LEAFP#10 datasheet, R5F104LEAFP#10 pinout, R5F104LEAFP#10 application, or R5F104LEAFP#10 equivalent, key selection criteria include its 48-pin LFQFP package, -40°C to +85°C industrial temperature grade (D suffix), 48 KB code flash with data flash shield window, and support for background data flash rewriting (BGO) at VDD = 1.8–5.5 V.
Technical Context
The R5F104LEAFP#10 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 RTC mode). It integrates a Data Transfer Controller (DTC) activated by 19–26 event sources via the Event Link Controller (ELC), enabling autonomous peripheral coordination without CPU intervention.
Its mixed-signal subsystem includes an 8/10-bit ADC with internal 1.45 V reference and temperature sensor, dual-channel 8-bit DAC with real-time output, and two comparators configurable in high-speed, low-speed, or window mode - all operating across the full 1.6–5.5 V supply range and qualified for industrial ambient temperatures.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104LEAFP#10?
The R5F104LEAFP#10 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. Its ultra-low-power design achieves 0.60 μA in STOP mode with RTC and LVD active - verified per R01DS0053EJ0370 datasheet Section 1.1. This makes R5F104LEAFP#10 suitable for applications where energy efficiency directly impacts battery service life.
Does the R5F104LEAFP#10 support in-system programming and secure firmware updates?
Yes, the R5F104LEAFP#10 supports full in-system programming via on-chip debug interface and includes flash shield window protection to prevent unauthorized read/write access to designated code or data flash regions. It also enables boot swapping and background data flash rewriting (BGO), allowing R5F104LEAFP#10 to execute application code while updating non-volatile storage - critical for secure over-the-air firmware deployment.
What analog peripherals are integrated into the R5F104LEAFP#10 and what are their key specifications?
The R5F104LEAFP#10 integrates a 10-bit ADC with 16 input channels, internal 1.45 V reference, and on-die temperature sensor; dual 8-bit DACs with 0–VDD output range and real-time waveform generation; and two comparators supporting high-speed, low-speed, and window modes. All operate across 1.6–5.5 V supply and -40°C to +85°C - confirmed in R01DS0053EJ0370 Sections 1.1 and 2.11. These capabilities make R5F104LEAFP#10 well-suited for closed-loop sensor conditioning and actuator control.
How does the Event Link Controller (ELC) enhance system efficiency in the R5F104LEAFP#10?
The ELC in the R5F104LEAFP#10 enables direct hardware linking of 19–26 peripheral events (e.g., timer overflow, ADC end-of-conversion, UART RX complete) to target functions (e.g., DTC trigger, ADC start, GPIO toggle) without CPU involvement. This offloads timing-critical tasks, reduces interrupt latency, and lowers CPU utilization - verified in R01DS0053EJ0370 Section 2.14. For R5F104LEAFP#10 deployments requiring deterministic response (e.g., motor control), ELC eliminates software jitter in peripheral coordination.
What is the industrial temperature grade and package type of the R5F104LEAFP#10?
The R5F104LEAFP#10 is rated for industrial operation from -40°C to +85°C (D-grade), packaged in a 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) with lead-free finish and RoHS compliance. The "FP" in the part number denotes LQFP, and "#10" specifies tray packaging - consistent with Renesas ordering conventions in R01DS0053EJ0370 Table 1-1. This makes R5F104LEAFP#10 appropriate for harsh environments including factory automation and outdoor metering.
