PIC16LC72-04/SP Equivalent & Substitute Parts

Part Overview

The PIC16LC72-04/SP is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, designed for embedded applications requiring low-power operation. This device features 4.6KB of OTP (One-Time Programmable) memory, 128 bytes of RAM, and integrated peripherals including PWM, watchdog timer, and brown-out detection. The part is currently active in production with verified programmability status and maintains full RoHS3 compliance.

Substitute parts are identified when equivalent functional capability can be achieved through alternative memory technologies or enhanced specifications while maintaining package compatibility and core I/O architecture.

Key Parameters

Substitute Part Grouping Explanation

The PIC16LF72-I/SP qualifies as a direct substitute based on the following alignment criteria:

Matching Parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Program memory capacity (4.6KB / 2K x 14)
• RAM configuration (128 x 8)
• I/O count (22 pins)
• Package type (28-DIP through-hole)
• Connectivity standards (I2C, SPI)
• Peripheral feature set (Brown-out Detect/Reset, POR, PWM, WDT)
• Data converter specification (A/D 5x8b)

Substitution Basis: The PIC16LF72-I/SP employs FLASH memory technology instead of OTP, enabling field reprogrammability while maintaining identical memory capacity and I/O architecture. This substitution is valid for applications where the enhanced speed specification and extended temperature range do not create conflicts with the original design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both devices maintain active product status and full RoHS3 compliance with identical ECCN and HTSUS classifications. The PIC16LF72-I/SP presents an enhanced specification profile through FLASH memory technology, enabling field reprogrammability compared to the OTP limitation of the PIC16LC72-04/SP. The substitute device operates at higher clock speed (20MHz vs. 4MHz) and supports an extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C), with a slightly reduced upper supply voltage limit (5.5V vs. 6V). Pin-for-pin package compatibility and identical I/O architecture ensure direct socket substitution feasibility. Selection between these devices depends on application requirements for memory reprogrammability, thermal operating range, and supply voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the PIC16LF72-I/SP directly replace the PIC16LC72-04/SP in existing designs?

A: Yes, the PIC16LF72-I/SP is pin-compatible and maintains identical I/O count, memory capacity, and peripheral feature set. Both devices use the 28-DIP through-hole package with 0.300" (7.62mm) spacing. Substitution is valid provided the application does not require operation above 5.5V supply voltage or below -40°C.

Q: What is the primary functional difference between these devices?

A: The PIC16LC72-04/SP uses OTP (One-Time Programmable) memory, while the PIC16LF72-I/SP employs FLASH memory technology. FLASH memory allows field reprogrammability, whereas OTP memory is programmed once during manufacturing and cannot be altered.

Q: Are there supply voltage compatibility considerations?

A: The PIC16LC72-04/SP operates from 2.5V to 6V, while the PIC16LF72-I/SP operates from 2V to 5.5V. Applications requiring supply voltages above 5.5V must use the original PIC16LC72-04/SP device.

Q: Do both devices support the same communication protocols?

A: Yes, both devices include I2C and SPI connectivity, identical peripheral features (Brown-out Detect/Reset, POR, PWM, WDT), and matching A/D converter specifications (5x8-bit).

Q: What is the temperature range difference?

A: The PIC16LC72-04/SP operates from 0°C to 70°C, while the PIC16LF72-I/SP supports -40°C to 85°C. Applications requiring operation below 0°C or above 70°C must use the PIC16LF72-I/SP.

Q: Are both devices RoHS compliant?

A: Yes, both devices are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications.
