Product details
Overview
R5F104LKAFB#30 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 512 KB flash, 24 KB RAM RL78/G14 16-bit microcontroller with ultra-low power operation (66 μA/MHz active, 0.60 μA RTC+LVD), 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 smart metering systems requiring long runtime and mixed-signal control.
For engineers reviewing the R5F104LKAFB#30 datasheet, R5F104LKAFB#30 pinout, R5F104LKAFB#30 application, or R5F104LKAFB#30 equivalent, key selection criteria include its 512 KB code flash capacity, 64-pin LFQFP-0.5 mm package, -40°C to +85°C industrial temperature grade (D), and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104LKAFB#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 an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention and a Data Transfer Controller (DTC) supporting block, repeat, and chain transfer modes activated by 19–26 event sources.
Its analog subsystem includes two independent 8-bit D/A converters with real-time output capability, a 10-bit A/D converter with up to 20 input channels and internal 1.45 V reference, and two comparator channels configurable in high-speed, low-speed, or window mode using either internal or external reference voltage.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104LKAFB#30?
The R5F104LKAFB#30 operates up to 32 MHz with a typical active current of 66 μA/MHz at VDD = 3.0 V and TA = 25°C. At full speed, this equates to approximately 2.1 mA total supply current. Its ultra-low-power STOP mode draws just 0.60 μA when only the RTC and LVD remain active - a critical specification for battery-backed real-time applications. These values are measured and guaranteed per the R01DS0053EJ0370 datasheet Rev. 3.70.
Does the R5F104LKAFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104LKAFB#30 supports full in-system programming via its on-chip debug interface (SWD-compatible) and includes robust security features: flash block erase/write prohibition, boot swapping for safe firmware updates, and flash shield window protection. The 8 KB data flash enables secure storage of encryption keys and calibration data, with background operation allowing updates without halting application execution - all confirmed in Section 1.1 of the R01DS0053EJ0370 datasheet.
What serial communication interfaces are available on the R5F104LKAFB#30 and how many channels does each support?
The R5F104LKAFB#30 integrates three serial interface types: up to 8 CSI (SPI-compatible) channels, up to 4 UART/LIN channels, and up to 10 I²C/simplified I²C channels. Pin multiplexing and peripheral I/O redirection registers allow flexible allocation across the 64-pin package. For example, P10–P17 support CSI11, I²C11, UART2, and analog comparator functions - details are specified in Table 1-1 and Figure 1.3.6 of the R01DS0053EJ0370 datasheet.
How is the analog subsystem configured on the R5F104LKAFB#30, and what reference options does it provide?
The R5F104LKAFB#30 includes a 10-bit A/D converter with up to 20 input channels, two 8-bit D/A converters, and two analog comparators. It provides an internal 1.45 V reference for ADC and comparator use, selectable against external references via register control. The AVREFP/AVREFM pins support differential reference inputs, and VCOUT0/VCOUT1 offer buffered voltage outputs for sensor excitation - all documented in Sections 1.1 and 1.3.6 of the R01DS0053EJ0370 datasheet.
What is the flash memory organization and endurance rating for data storage on the R5F104LKAFB#30?
The R5F104LKAFB#30 contains 512 KB of code flash memory organized in 1 KB blocks and 8 KB of data flash memory rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V.
