Product details
Overview
R7FA4E10B2CNE#AA0 from Renesas is a 32-bit Arm Cortex-M33 microcontroller operating at up to 100 MHz, featuring 256 KB code flash, 8 KB data flash, 128 KB SRAM with parity, USB 2.0 Full-Speed, Quad SPI, CAN 2.0B, and integrated 12-bit ADC/DAC. It targets industrial control, smart sensors, and USB-connected edge devices requiring secure, low-power operation.
For engineers reviewing the R7FA4E10B2CNE#AA0 datasheet, R7FA4E10B2CNE#AA0 pinout, R7FA4E10B2CNE#AA0 application, or R7FA4E10B2CNE#AA0 equivalent, key selection criteria include its QFN-48 package, TrustZone-enabled security partitioning, battery-backed RTC with VBATT support, and dual GPT32/GPT16 timer architecture for real-time motor or power control.
Technical Context
The R7FA4E10B2CNE#AA0 implements Armv8-M with TrustZone, enabling secure/non-secure world separation across memory (flash/SRAM), peripherals, and MPU regions. Its clock system integrates HOCO/MOCO/LOCO oscillators plus PLL, with CAC for frequency accuracy validation and ELC for CPU-free peripheral event chaining.
It supports deterministic real-time operation via five AGT timers (16-bit, asynchronous), two GPT32 channels (32-bit PWM), and hardware-accelerated data movement using DMAC (8-channel) and DTC. The analog subsystem includes nine-channel 12-bit ADC12 and single-channel DAC12 with dedicated reference pins (VREFH0/VREFL0).
