Product details
Overview
R5F104LFAFA#30 from Renesas is a 64-pin LQFP (0.65 mm pitch), 512 KB flash, 48 KB RAM RL78/G14 16-bit MCU with ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD mode), 1.6–5.5 V supply, and integrated peripherals including 12-channel 10-bit ADC, dual DAC, RTC, and multiple serial interfaces. It targets battery-powered industrial sensors and low-power HMI control units.
For engineers reviewing the R5F104LFAFA#30 datasheet, R5F104LFAFA#30 pinout, R5F104LFAFA#30 application, or R5F104LFAFA#30 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, 512 KB code flash with 1 KB block erase, 48 KB RAM, 12-channel 10-bit ADC with internal reference, and support for LIN-compliant UART channels in industrial temperature grade (−40°C to +85°C).
Technical Context
The R5F104LFAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a Data Transfer Controller (DTC) for autonomous memory transfers and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and background operation (BGO) for data flash rewriting while executing program code. The high-accuracy ±1.0% on-chip oscillator supports 12 selectable frequencies from 1 to 64 MHz across full voltage and temperature range.

FAQ
What is the operating temperature range for R5F104LFAFA#30?
The R5F104LFAFA#30 is qualified for industrial applications with an operating ambient temperature range of −40°C to +85°C (D-field grade). This specification is confirmed in the RL78/G14 datasheet Rev. 3.70, Table 1-1 ordering information, and applies to all R5F104Lx series parts ending in 'D' or 'F' suffixes. It does not support the extended −40°C to +105°C (G-field) range.
Does R5F104LFAFA#30 support LIN bus communication?
Yes, R5F104LFAFA#30 supports LIN bus communication through its UART channels (UART0–UART3), which include LIN-specific features such as break detection, sync field handling, and checksum calculation per LIN 2.2. The datasheet explicitly lists "UART/UART (LIN-bus supported)" under Serial Interfaces, and pin functions like P13/TxD2 and P14/RxD2 are designated for LIN transceiver interfacing.
What is the flash memory organization and erase granularity of R5F104LFAFA#30?
R5F104LFAFA#30 contains 512 KB of on-chip code flash memory organized in 1 KB blocks. Erase operations occur at the block level only; individual sector or page erase is not supported. The datasheet confirms this block size in Section 1.1 "Features" and specifies that block erase prohibition is available as a security function to protect critical firmware sections.
How much RAM is available on R5F104LFAFA#30, and where is the flash library RAM located?
R5F104LFAFA#30 integrates 48 KB of on-chip RAM. Per the RL78/G14 datasheet Rev. 3.70 page 2, the flash self-programming library uses RAM starting at address F3F00H. This dedicated region is reserved for flash write/erase routines and must be excluded from application variable allocation to avoid corruption during firmware updates.
What package type and pin pitch does R5F104LFAFA#30 use?
R5F104LFAFA#30 uses a 64-pin LQFP package with 0.65 mm pin pitch, as indicated by the 'FA' suffix in the part number and confirmed in Table 1-1 of the datasheet. The Renesas code PLQP0064JA-A identifies this variant, and the mechanical drawing specifies 12 × 12 mm body size with standard gull-wing leads compatible with automated SMT assembly.
