PIC16LC67T-04I/L Equivalent & Substitute Parts

Part Overview

The PIC16LC67T-04I/L is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 14KB OTP program memory, 368 x 8 bytes of RAM, and 33 I/O pins in a 44-PLCC package. The device operates at 4MHz with a supply voltage range of 2.5V to 6V and includes integrated peripherals such as PWM, WDT, Brown-out Detect/Reset, and POR functionality.

The main part is classified as Obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility is required for new production runs. Active alternatives with identical electrical and mechanical specifications are available to maintain design compatibility.

Substitute Part Grouping Explanation

Substitution for the PIC16LC67T-04I/L is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 14KB OTP program memory (8K x 14), 368 x 8 RAM
• Operating Frequency: 4MHz
• Supply Voltage Range: 2.5V ~ 6V
• I/O Count: 33 pins
• Peripheral Set: I2C, SPI, UART/USART, PWM, WDT, Brown-out Detect/Reset, POR
• Package Specification: 44-PLCC (16.59x16.59) with 44-LCC J-Lead configuration
• Temperature Range: -40°C ~ 85°C

The PIC16LC67-04I/L meets all substitution criteria as a direct equivalent with identical electrical and mechanical characteristics. The primary distinction is product status: the substitute part is Active, whereas the main part is Obsolete.
