Product details
Overview
R5F104AFASP#30 from Renesas is a 30-pin LSSOP-packaged RL78/G14 16-bit microcontroller with 64 KB flash, 5.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), integrated 10-bit ADC (20 ch), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F104AFASP#30 datasheet, R5F104AFASP#30 pinout, R5F104AFASP#30 application, or R5F104AFASP#30 equivalent, key selection criteria include its 30-pin LSSOP-0.65mm package, 64 KB code flash with security lock, 10-bit ADC with internal reference and temperature sensor, and support for LIN-bus UART channels in consumer-grade (-40 to +85°C) operation.
Technical Context
The R5F104AFASP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting normal/repeat/block transfer modes triggered by 19–26 event sources via the Event Link Controller (ELC).
Its peripheral set includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, calendar-capable RTC with alarm/correction, watchdog timer, and simplified SPI (CSI), UART/LIN, and I²C interfaces - all optimized for deterministic low-power embedded control with background data flash rewriting (BGO) and self-programming capability.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104AFASP#30?
The R5F104AFASP#30 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. Its high-accuracy on-chip oscillator supports frequencies from 1 to 64 MHz with ±1.0% tolerance over 1.8–5.5 V and -20 to +85°C. This enables deterministic real-time execution in motor control and sensor fusion applications without requiring external crystals for basic operation - though X1/X2 pins support optional 32.768 kHz or MHz crystals for enhanced timing accuracy or RTC synchronization.
Does the R5F104AFASP#30 support in-system programming and secure firmware updates?
Yes, the R5F104AFASP#30 supports full in-system programming via on-chip debug interface and includes flash shield window protection, per-block erase/write prohibition, and boot swapping for safe firmware updates. Its self-programming capability allows field upgrades without external programmers, and the 4 KB data flash supports background operation (BGO), enabling concurrent code execution and nonvolatile parameter storage - critical for maintaining calibration data and usage logs during R5F104AFASP#30 runtime.
How many analog input channels and what resolution does the ADC in the R5F104AFASP#30 provide?
The R5F104AFASP#30 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated inputs for internal temperature sensor and voltage references. It supports selectable conversion clocks, scan mode, and built-in 1.45 V internal reference - eliminating need for external precision references in most sensor interface designs. The ADC operates across the full 1.6–5.5 V supply range, making it suitable for direct battery-voltage monitoring and multi-sensor signal conditioning within the R5F104AFASP#30.
What serial communication interfaces are available on the R5F104AFASP#30, and are they LIN-compliant?
The R5F104AFASP#30 provides three UART channels, all supporting LIN 2.2 protocol including automatic sync-break detection, checksum calculation, and slave node response timing - confirmed in the RL78/G14 hardware manual. It also includes 3–8 CSI (SPI-compatible) channels and 4–10 I²C/simplified I²C channels, with flexible pin assignment via peripheral I/O redirection registers (PIOR0/1). These interfaces enable mixed-protocol communication in automotive body electronics and industrial control networks using the R5F104AFASP#30 as central coordinator.
What is the operating temperature range and qualification level of the R5F104AFASP#30?
The R5F104AFASP#30 is qualified for consumer applications ('A' grade) with an operating ambient temperature range of -40 to +85°C. It meets industrial-grade reliability testing per Renesas standard protocols but is not rated for extended industrial (-40 to +105°C) or automotive AEC-Q100 environments. This makes it ideal for indoor consumer electronics, white goods, and commercial building automation where thermal margins remain within the R5F104AFASP#30 specification - verified in the official RL78/G14 datasheet Rev. 3.70.
