PIC16LC770-E/P Equivalent & Substitute Parts

Part Overview

The PIC16LC770-E/P is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 4.6KB OTP program memory, 256 bytes of RAM, and integrated peripherals including PWM, watchdog timer, and brown-out detection. This device operates across a wide voltage range (2.5V to 5.5V) and temperature range (-40°C to 125°C), making it suitable for embedded control applications requiring low-power operation.

The PIC16LC770-E/P is classified as obsolete. Locating equivalent or substitute components is necessary for system redesign, production continuation, or inventory replenishment when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16LC770-E/P is determined by the following critical parameters:

• Core Processor & Architecture: Must be PIC microcontroller to maintain instruction set compatibility
• Core Size: Must remain 8-Bit
• Program Memory: 4.6KB OTP minimum requirement
• RAM: 256 x 8 bytes minimum
• Speed: 20MHz operation capability
• Voltage Supply Range: 2.5V ~ 5.5V compatibility
• Package: 20-DIP form factor for mechanical and electrical pin compatibility
• Connectivity & Peripherals: I2C, SPI, PWM, WDT, brown-out detection, and POR functionality

The PIC16LC770-I/P meets all these criteria and qualifies as a direct substitute. Both parts share identical core specifications, memory configuration, and peripheral set. The primary difference is product status and operating temperature range, which does not affect functional substitution in applications designed for the PIC16LC770-E/P.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC770-I/P is a direct functional substitute for the PIC16LC770-E/P. Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The PIC16LC770-I/P is currently in active production status, whereas the PIC16LC770-E/P is obsolete. Selection of the PIC16LC770-I/P ensures long-term availability and supply chain continuity.

The operating temperature range difference (-40°C ~ 85°C for the I/P variant versus -40°C ~ 125°C for the E/P variant) should be evaluated against application requirements. Applications operating within the -40°C ~ 85°C range face no functional limitation with the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the PIC16LC770-I/P directly replace the PIC16LC770-E/P in existing designs?

A: Yes. Both parts share identical core architecture, memory configuration, pin count, package form factor, and peripheral functionality. No circuit modifications are required for substitution.

Q: What is the difference between the PIC16LC770-E/P and PIC16LC770-I/P?

A: The primary differences are product status and operating temperature range. The E/P variant is obsolete with a -40°C ~ 125°C operating range. The I/P variant is active production with a -40°C ~ 85°C operating range. All electrical and functional specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 20-DIP (0.300", 7.62mm) package. The E/P variant uses standard packaging, while the I/P variant is supplied in tube packaging. Pin configuration and mechanical dimensions are identical.

Q: Do both parts meet current compliance standards?

A: Yes. Both the PIC16LC770-E/P and PIC16LC770-I/P are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Which part should be selected for new designs?

A: The PIC16LC770-I/P should be selected for new designs due to its active production status and guaranteed long-term availability. The PIC16LC770-E/P is obsolete and should not be specified for new development.
