Product details
Overview
R7FA0E1073CNL#BA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller in a 16-pin HWQFN package, operating up to 32 MHz with 64-KB code flash, 12-KB SRAM, and integrated 12-bit ADC, RTC, and safety features including SRAM parity, IWDT, and CRC. It targets battery-powered industrial sensors and compact IoT edge nodes requiring functional safety and mixed-signal integration.
For engineers reviewing the R7FA0E1073CNL#BA0 datasheet, R7FA0E1073CNL#BA0 pinout, R7FA0E1073CNL#BA0 application, or R7FA0E1073CNL#BA0 equivalent, key selection criteria include its 16-pin HWQFN footprint, 12-KB parity-protected SRAM, 10-channel ADC with temperature sensor input, LIN-capable UART, and support for -40°C to +105°C operation in space-constrained designs.
Technical Context
The R7FA0E1073CNL#BA0 implements the Armv8-M architecture with TrustZone®-enabled security extensions, featuring a single-cycle integer multiplier and 19-cycle divider. Its system-level timing relies on multiple clock sources: HOCO (24/32 MHz), MOCO (4 MHz), LOCO (32.768 kHz), and external crystal support via X1/X2 pins.
Peripheral integration includes an Event Link Controller (ELC) enabling CPU-free inter-module triggering, a Data Transfer Controller (DTC) for interrupt-driven memory transfers, and a Timer Array Unit (TAU) with eight 16-bit channels supporting PWM and capture functions - all operating under low-power modes with LVD monitoring and register write protection.
