Product details
Overview
R5F104LHGFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G14 16-bit MCU with 512 KB flash, 8 KB data flash, 48 KB RAM, and operation up to 32 MHz delivering 44 DMIPS - deployed in battery-powered sensor nodes, motor control interfaces, and industrial HMI panels requiring ultra-low power and mixed-signal integration.
For engineers reviewing the R5F104LHGFB#30 datasheet, R5F104LHGFB#30 pinout, R5F104LHGFB#30 application, or R5F104LHGFB#30 equivalent, key selection criteria include its 0.60 μA RTC+LVD stop-mode current, 16–512 KB scalable flash architecture, integrated 10-bit 20-channel ADC with temperature sensor, and dual UART/LIN + I²C + CSI serial support for deterministic peripheral communication.
Technical Context
The R5F104LHGFB#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-power mode). It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event routing without CPU intervention.
Its analog subsystem includes a 10-bit ADC with internal 1.45 V reference and on-die temperature sensor, plus two 8-bit DAC channels with real-time output capability and programmable output voltage range (0 V to VDD). The MCU supports background operation (BGO) during data flash rewriting at full VDD range (1.8–5.5 V).

FAQ
What is the operating temperature range for the R5F104LHGFB#30?
The R5F104LHGFB#30 is rated for industrial operation from −40°C to +105°C, confirmed by Renesas datasheet section 1.1 under "Operating Ambient Temperature" with "G" grade designation. This allows deployment in harsh environments such as factory-floor controllers, outdoor utility meters, and under-hood automotive subsystems where extended thermal stability is required. The R5F104LHGFB#30 maintains full specification compliance across this range without derating.
Does the R5F104LHGFB#30 support in-circuit debugging without external hardware?
Yes, the R5F104LHGFB#30 includes an on-chip debug function compatible with Renesas E2 emulator and standard SWD/JTAG interfaces. Debug access uses dedicated pins (e.g., RESET, TOOL0) and requires no external debug probe circuitry beyond standard 10-pin SWD header connection. The R5F104LHGFB#30 supports breakpoints, watchpoints, and real-time variable monitoring directly through the integrated debug module per Section 1.1 "Code Flash Memory".
How many UART/LIN channels does the R5F104LHGFB#30 provide, and are they hardware-supported?
The R5F104LHGFB#30 provides four fully hardware UART channels with built-in LIN bus support (including break detection, sync field handling, and checksum calculation), as specified in Section 1.1 "Serial Interfaces". Each channel operates independently with dedicated baud rate generators and FIFO buffers - no software bit-banging required. The R5F104LHGFB#30's UART2 and UART3 also support automatic direction control for RS-485 transceivers via dedicated control pins.
Can the R5F104LHGFB#30 perform ADC conversions while in low-power STOP mode?
No - ADC operation is disabled in STOP mode per Section 1.1 "Ultra-Low Power Consumption Technology". However, the R5F104LHGFB#30 supports HALT mode (66 μA/MHz) with ADC enabled, and SNOOZE mode allows selective peripheral operation (e.g., periodic ADC sampling triggered by RTC alarm) while CPU remains halted. For continuous low-power sensing, the R5F104LHGFB#30 must use HALT or SNOOZE, not STOP.
What packaging and lead finish does the R5F104LHGFB#30 use?
The R5F104LHGFB#30 uses a 64-pin LFQFP package (10 × 10 mm, 0.5 mm pitch) with matte tin lead finish, as defined in Table 1-1 "Ordering Part Numbers" and Figure 1-1. The "FB" suffix explicitly denotes LFQFP, and "#30" indicates embossed tape packaging per Renesas packaging specification. This package is compatible with standard reflow profiles and supports automated pick-and-place assembly.
