Product details
Overview
R5F11BBEAFP#10 from Renesas is a 32-pin LQFP (7 × 7 mm, 0.8 mm pitch), 64 KB flash, 5.5 KB RAM RL78/G1F microcontroller operating at up to 32 MHz with true low-power operation (66 μA/MHz active, 0.57 μA in RTC+LVD mode), 1.6–5.5 V supply, and integrated 8/10-bit ADC (13 channels), dual 8-bit DAC, two comparators, and programmable gain amplifier - deployed in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F11BBEAFP#10 datasheet, R5F11BBEAFP#10 pinout, R5F11BBEAFP#10 application, or R5F11BBEAFP#10 equivalent, this page delivers verified functional specifications, validated I/O mapping for LQFP-32 package, real-world use cases in low-voltage sensing and LIN-bus motor control, and technically grounded alternative part guidance - all derived from Renesas' official RL78/G1F datasheet Rev.1.30.
Technical Context
The R5F11BBEAFP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-speed on-chip oscillator (±1.0% accuracy across 1.8–5.5 V) and supports HALT, STOP, and SNOOZE low-power modes with hardware-assisted wake-up via 11 external interrupt pins (INTP0–INTP11).
Peripherals include Timer Array Unit (TAU) with 4 channels, Timer RD (2-channel PWMOPA-capable), Timer RG, Timer RX, RTC with calendar and alarm, 3 UART/LIN channels, 3 simplified I²C interfaces, and Event Link Controller (ELC) enabling 22 event sources to trigger peripheral functions without CPU intervention - enabling deterministic real-time response in resource-constrained embedded systems.
