Substitute Part Grouping Explanation

Substitution of the FS32R274KBK2MMM is determined by strict equivalence across the following critical parameters:

• Core processor architecture: e200z4, e200z7 (2) dual-core configuration
• Core size: 32-Bit Tri-Core
• Operating frequency: 180MHz, 240MHz capability
• Program memory: 2MB FLASH (2M x 8)
• EEPROM capacity: 64K x 8
• RAM capacity: 1.5M x 8
• Supply voltage range: 1.19V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C
• Package: 257-LFBGA (14x14)
• Mounting type: Surface Mount

The substitute part FS32R274KSK2MMM maintains identical core specifications, memory configuration, voltage ratings, and thermal operating range. The primary distinction is product status (Active vs. Obsolete) and packaging format (Tray vs. standard packaging), with the substitute offering expanded connectivity options including Ethernet, FlexRay, and ZipWire in addition to the base CANbus, FlexIO, I2C, LINbus, and SPI interfaces.
