The Renesas R7FA2L1AB3CFL#BA0 is a 32-bit ultra-low-power general-purpose microcontroller from the RA2L1 Series, based on the Arm Cortex-M23 CPU core. It operates at up to 48MHz and integrates 256KB program Flash, 8KB Data Flash and 32KB SRAM. With a wide operating voltage range of 1.6V to 5.5V, it is well suited for energy-efficient embedded and battery-powered applications.
The device is supplied in a 48-pin LQFP package measuring 7 × 7 × 1.7mm with a 0.5mm pitch. It provides a comprehensive set of communication and analog peripherals, including 5 SCI/UART channels, 2 SPI channels, 2 I²C interfaces, 1 CAN channel, a 9-channel 12-bit ADC, a 1-channel 12-bit DAC and 2 analog comparators. It also incorporates a 20-channel capacitive touch sensing unit for touch-based human-machine interface applications.
Additional integrated functions include RTC, watchdog timers, multiple general-purpose timers and a Data Transfer Controller (DTC). Security capabilities include AES-128/256 encryption, TRNG and Unique ID. With an operating temperature range of -40°C to +105°C, the R7FA2L1AB3CFL#BA0 is suitable for industrial controls, smart home devices, sensors, portable electronics, metering systems and low-power HMI applications.
