Product details
Overview
R5F100LHGFA#V0 from Renesas is a 64-pin LQFP-0.65mm, 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit MCU with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), 32 MHz max CPU speed, and integrated 10-bit ADC (26 channels), RTC, UART, I²C, and SPI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LHGFA#V0 datasheet, R5F100LHGFA#V0 pinout, R5F100LHGFA#V0 application, or R5F100LHGFA#V0 equivalent, key selection considerations include its -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent code execution during firmware updates.
Technical Context
The R5F100LHGFA#V0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting variable instruction timing from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates dual-clock domains: a high-speed main system clock (up to 32 MHz) and a dedicated low-speed on-chip oscillator for watchdog and RTC operation.
Its peripheral set includes 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 2–4 DMA channels, and serial interfaces configured as CSI (SPI-compatible), UART/LIN, and I²C - all mapped to dedicated SFRs with configurable interrupt priority and clock gating for dynamic power management.
