Substitute Part Grouping Explanation

Substitution for the PIC16C54T-RC/SS is determined by strict equivalence across the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating speed (4MHz)
• Program memory capacity and type (768B OTP)
• RAM configuration (25 x 8)
• I/O pin count (12)
• Supply voltage range (3V ~ 6.25V)
• Package type and dimensions (20-SSOP)
• Peripheral set (POR, WDT)
• Operating temperature range (0°C ~ 70°C)

The PIC16C54-RC/SS meets all these criteria as a direct equivalent. This part maintains identical electrical and mechanical specifications while offering active product status and verified programmability through DiGi-Electronics.
