Product details
Overview
R7FA2L1AB2DFL#AA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 256 KB code flash, 32 KB SRAM, 12-bit ADC/DAC, Capacitive Touch Sensing Unit (CTSU2), and integrated CAN 2.0A/B interface - deployed in battery-powered HMI control panels requiring secure, low-power sensing and real-time communication.
For engineers reviewing the R7FA2L1AB2DFL#AA0 datasheet, R7FA2L1AB2DFL#AA0 pinout, R7FA2L1AB2DFL#AA0 application, or R7FA2L1AB2DFL#AA0 equivalent, this page delivers verified package mapping (48-pin LQFP), confirmed CTSU2 touch channel count (up to 32), CAN mailbox configuration (32 mailboxes), RTC calendar mode (2000–2099), and ECC-protected SRAM - all validated against Renesas R01DS0385EJ0160 Rev.1.60.
Technical Context
The R7FA2L1AB2DFL#AA0 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling secure firmware partitioning and deterministic debug in safety-critical embedded systems. Its clock system integrates HOCO (48 MHz), SOSC (32.768 kHz), and IWDT-dedicated 15 kHz oscillator for fail-safe timing independence.
Peripheral coherency is enforced via Event Link Controller (ELC), allowing direct hardware-triggered actions between modules (e.g., ADC conversion start → DMA transfer) without CPU intervention. The Data Transfer Controller (DTC) supports automatic data movement on interrupt, reducing CPU load during sensor acquisition or CAN message handling.
