Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC770T-I/SO is determined by strict alignment across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Program Memory: 4.6KB (2K x 14) OTP
• RAM Configuration: 256 x 8 bytes
• Operating Speed: 20MHz maximum
• I/O Count: 15 pins
• Supply Voltage Range: 2.5V ~ 5.5V
• Package Type: 20-SOIC form factor
• Peripheral Set: I2C, SPI, PWM, WDT, brown-out detection, POR

The substitute part PIC16LC770-I/SO meets all these criteria, differing only in product status (active vs. obsolete) and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC770-I/SO is a direct functional equivalent to the PIC16LC770T-I/SO. Both devices are ROHS3 compliant and carry identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the main part is obsolete while the substitute is active, with significantly higher inventory availability (2300 pcs vs. 1060 pcs). For new designs or ongoing production requiring this microcontroller class, the PIC16LC770-I/SO is the appropriate selection. Both parts maintain identical compliance certifications (REACH Unaffected, EAR99 ECCN classification) and moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can PIC16LC770-I/SO be used as a direct replacement for PIC16LC770T-I/SO?

A: Yes. Both parts share identical core architecture, memory configuration, I/O count, speed rating, supply voltage range, peripheral set, and 20-SOIC package. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. PIC16LC770T-I/SO is obsolete; PIC16LC770-I/SO is active production. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences?

A: No. Both devices use the 20-SOIC (0.295", 7.50mm Width) package with identical pinout and 15 I/O pins.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified as EAR99 under ECCN. Both carry MSL rating 1 (unlimited moisture sensitivity level).

Q: Which part should be selected for new procurement?

A: PIC16LC770-I/SO should be selected for new designs and ongoing production due to active status and superior inventory availability.
