Substitute Part Grouping Explanation

Substitute parts for the ATSAM4E8CA-ANR are determined by strict equivalence across the following electrical and mechanical parameters:

Manufacturer and Series: Both parts must be Microchip Technology SAM4E series microcontrollers
Core Architecture: ARM Cortex-M4 32-bit single-core processor
Operating Frequency: 120MHz
Memory Configuration: 512KB FLASH and 128K x 8 RAM
I/O Count: 79 I/O pins
Package: 100-LQFP (14x14) surface mount
Voltage Range: 1.62V ~ 3.6V supply
Connectivity: CANbus, Ethernet, IrDA, MMC/SD, SPI, UART/USART, USB
Peripherals: Brown-out Detect/Reset, DMA, POR, PWM, WDT
Data Converters: A/D 16x12b and D/A 2x12b
Compliance: ROHS3 Compliant, REACH Unaffected

The ATSAM4E8CB-ANR meets all these criteria and qualifies as a direct substitute. The primary difference is packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format.
