Overview
R5F140GLGFB#30 from Renesas is a 48-pin LFQFP, industrial-grade RL78/G13A 16-bit microcontroller with 512 KB code flash, 32 KB RAM, and 8 KB data flash. It operates from 1.6–5.5 V, achieves ultra-low 47 µA/MHz active current, supports −40 to +105°C ambient, and integrates UART/LIN, I²C, CSI, RTC, and 10-channel 8/10-bit ADC - deployed in motor control and smart appliance HMI subsystems.
For engineers reviewing the R5F140GLGFB#30 datasheet, R5F140GLGFB#30 pinout, R5F140GLGFB#30 application, or R5F140GLGFB#30 equivalent, this page delivers verified package mapping (LFQFP-48), confirmed 48-pin terminal roles, real-world timing and interface constraints, and two validated alternative parts for industrial temperature-grade RL78 migration paths.
Technical Context
The R5F140GLGFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory architecture includes 512 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 32 KB on-chip RAM.
Peripherals include 8-channel 16-bit timer array, 12-bit interval timer, real-time clock with calendar and alarm, watchdog timer, 2-channel DMA, multiplier/divider/MAC unit, and serial interfaces: up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI channels - all configurable via peripheral I/O redirection register (PIOR).
