Substitute Part Grouping Explanation

Substitution eligibility for the C8051F930-F-GQ is determined by strict equivalence across the following critical parameters:

• Core processor architecture (8051)
• Core size (8-Bit)
• Clock speed (25MHz)
• Program memory capacity and type (64KB FLASH)
• RAM capacity (4.25K x 8)
• Supply voltage range (0.9V ~ 3.6V)
• Integrated peripherals (SMBus/I2C, SPI, UART/USART, A/D converters)
• I/O pin count (24)
• Package form factor (32-LQFP 7x7)
• Operating temperature range (-40°C ~ 85°C)

The C8051F930-G-GQ meets all substitution criteria as a direct equivalent within the C8051F9xx series, with identical electrical and mechanical specifications. The primary distinction is product status and packaging configuration.
