Product details
Overview
R5F11FLJANA#40 from Renesas Electronics is a 16-bit RL78/G1H microcontroller with 256 KB Flash, 24 KB RAM, and 8 KB data flash, operating at up to 32 MHz. It integrates 10-bit ADC (6 channels), dual I²C/UART/CSI interfaces, RTC, and supports 920 MHz radio communication in low-power embedded systems.
For engineers reviewing the R5F11FLJANA#40 datasheet, R5F11FLJANA#40 pinout, R5F11FLJANA#40 application, or R5F11FLJANA#40 equivalent, key selection factors include its HVQFN-64 package, 1.8–3.6 V supply range, -40 to +85 °C operation, integrated 9-channel 16-bit timers, and dual I²C support for sensor hub and wireless node designs.
Technical Context
The R5F11FLJANA#40 implements the RL78 CPU core with sub-clock (32.768 kHz) and on-chip oscillators (1–32 MHz), enabling flexible clock source selection for ultra-low-power operation. It includes hardware real-time clock (RTC) with calendar function and low-voltage detection circuitry for robust system monitoring.
Its peripheral set features nine 16-bit general-purpose timers, one watchdog timer, and a 12-bit interval timer-supporting precise timing control in battery-powered wireless nodes. The 10-bit ADC has six input channels with internal reference, suitable for analog sensor interfacing without external components.
