Product details
Overview
R5F104AFGSP#30 from Renesas is a 30-pin LSSOP-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, RTC, and on-chip oscillators for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F104AFGSP#30 datasheet, R5F104AFGSP#30 pinout, R5F104AFGSP#30 application, or R5F104AFGSP#30 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options - all aligned to the official RL78/G14 Rev. 3.70 specification.
Technical Context
The R5F104AFGSP#30 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 ultra-low-speed mode). It includes dedicated hardware blocks for background data flash rewriting (BGO), event linking (ELC), and data transfer (DTC), enabling deterministic real-time response without CPU intervention.
Its peripheral set is configured for mixed-signal industrial control: dual UART channels (one with LIN support), up to 10 I²C/Simplified I²C channels, 12-channel 16-bit timer array (TAU), 12-bit interval timer, and analog subsystem with internal 1.45 V reference and temperature sensor - all powered from a single supply rail with integrated POR and 14-level LVD.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104AFGSP#30?
The R5F104AFGSP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS performance. This is confirmed in the RL78/G14 datasheet Rev. 3.70 Section 1.1, where 44 DMIPS is explicitly specified for the 32 MHz configuration. The R5F104AFGSP#30 achieves this with zero wait-state execution on code flash at this frequency.
Does the R5F104AFGSP#30 include a built-in temperature sensor and internal voltage reference?
Yes, the R5F104AFGSP#30 integrates both a temperature sensor and an internal 1.45 V voltage reference, as documented in Section 1.1 "Features" of the RL78/G14 datasheet Rev. 3.70. These analog resources are accessible through the 10-bit ADC and require no external components - enabling accurate thermal monitoring and stable analog measurements in the R5F104AFGSP#30.
How many serial communication interfaces does the R5F104AFGSP#30 support, and what protocols are implemented?
The R5F104AFGSP#30 supports three UART channels (one with LIN-bus support), up to eight CSI (SPI-compatible) channels, and four to ten I²C/simplified I²C channels - all confirmed in Section 1.1 "Serial Interfaces" of the RL78/G14 datasheet Rev. 3.70. The exact count depends on pin multiplexing, but the R5F104AFGSP#30's 30-pin LSSOP package enables at least two UARTs, three CSIs, and four I²C interfaces simultaneously.
What is the data flash endurance and rewrite voltage range for the R5F104AFGSP#30?
The R5F104AFGSP#30 includes 8 KB of data flash memory rated for 1,000,000 rewrite cycles (typical), with operation supported across the full supply range of VDD = 1.8 to 5.5 V - as specified in Section 1.1 "Data Flash Memory" of the RL78/G14 datasheet Rev. 3.70. Background operation (BGO) allows concurrent program execution during rewrites.
Is the R5F104AFGSP#30 qualified for industrial temperature range, and what is the exact specification?
Yes, the R5F104AFGSP#30 is qualified for the industrial temperature range of -40 to +105°C, indicated by the "G" suffix in its part number per Section 1.2 "Ordering Information" of the RL78/G14 datasheet Rev. 3.70. This G-grade qualification applies specifically to the R5F104AFGSP#30 and is validated across all electrical parameters in the datasheet's "Operating Ambient Temperature" table.
