Product details
Overview
R5F11BGCGFB#30 from Renesas Electronics is a 48-pin LFQFP, 64 KB flash, 5.5 KB RAM RL78/G1F 16-bit microcontroller operating from 1.6 V to 5.5 V at up to 32 MHz CPU frequency. It integrates 17-channel 8/10-bit ADC, dual 8-bit DAC, two comparators, PGA, RTC with calendar, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD), targeting industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F11BGCGFB#30 datasheet, R5F11BGCGFB#30 pinout, R5F11BGCGFB#30 application, or R5F11BGCGFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, industrial −40°C to +105°C rating, integrated LIN-capable UART, 17 analog inputs, and hardware event-linking via ELC for deterministic peripheral coordination.
Technical Context
The R5F11BGCGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It supports self-programming with boot swap and flash shield window functions, enabling secure firmware updates without external programming hardware.
Its peripheral set includes Timer Array Unit (TAU) with 4 channels, Timer RD with PWMOPA for motor control, Event Link Controller (ELC) linking 22 event sources to peripherals, and Data Transfer Controller (DTC) supporting chain transfers triggered by 32 interrupt sources - all optimized for deterministic real-time response in resource-constrained industrial environments.
