Product details
Overview
R5F11BGEAFB#10 from Renesas Electronics is a 48-pin LFQFP, 64 KB flash, 5.5 KB RAM RL78/G1F 16-bit microcontroller operating at up to 32 MHz with true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 17-channel 8/10-bit ADC, dual 8-bit DAC, and integrated PGA-designed for battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F11BGEAFB#10 datasheet, R5F11BGEAFB#10 pinout, R5F11BGEAFB#10 application, or R5F11BGEAFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, industrial-grade −40°C to +105°C operation, dual UART/LIN support, hardware event linking (ELC) for deterministic peripheral triggering, and on-chip debug with flash shield window security.
Technical Context
The R5F11BGEAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a 12-bit interval timer, real-time clock with calendar and alarm, and watchdog timer driven by a dedicated low-speed on-chip oscillator.
Its analog subsystem includes two comparators (one with pin-selectable input), programmable gain amplifier (PGA), and 17 analog inputs routed to an 8/10-bit ADC with internal 1.45 V reference and temperature sensor-enabling closed-loop control and precision sensing without external signal conditioning.
