R7FA2L1AB3CFL#AA0 Product Overview
The Renesas R7FA2L1AB3CFL#AA0 device features a 48MHz Arm Cortex-M23 core (Armv8-M architecture), the most energy-efficient CPU among Arm Cortex-M. Through optimized processing and Renesas' low-power process technology, the RA2L1 group achieves industry-leading ultra-low-power performance. Operating voltage ranges from 1.6V to 5.5V, with an industrial temperature range of -40℃ to +105℃. It integrates 256KB code flash, 32KB SRAM with ECC, and 8KB data flash (100,000 P/E cycles), with an enhanced second-generation Capacitive Touch Sensing Unit (CTSU2), 12-bit ADC (13 channels), 12-bit DAC (1 channel), 32-bit general PWM timer, 16-bit general PWM timer, low-power asynchronous general-purpose timer, and RTC. Connectivity includes 5× SCI (UART/simple SPI/simple I²C/SmartCard), 2× SPI, 2× I²C, and 1× CAN module. Security features include AES128/AES256 hardware encryption, TRNG, and a 128-bit unique ID. It comes in an LFQFP-48(7×7mm) package with 37 I/O ports, compliant with IEC60730 appliance safety standard.
