PIC16LC62AT-04/SS Equivalent & Substitute Parts

Part Overview

The PIC16LC62AT-04/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 4.6KB OTP program memory, 128 x 8 bytes of RAM, and 22 I/O pins in a 28-SSOP surface mount package. This device operates at 4MHz with a supply voltage range of 2.5V to 6V and includes integrated peripherals such as brown-out detection, power-on reset, PWM, and watchdog timer functionality.

The PIC16LC62AT-04/SS is classified as obsolete. Locating equivalent substitute parts is necessary to support legacy system maintenance, design updates, and production continuity where original inventory is unavailable or depleted.

Substitute Part Grouping Explanation

Substitution of the PIC16LC62AT-04/SS is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: PIC processor family
• Core Size: 8-Bit processing capability
• Operating Speed: 4MHz clock frequency
• Program Memory: 4.6KB OTP capacity
• RAM Configuration: 128 x 8 byte organization
• I/O Pin Count: 22 pins minimum
• Supply Voltage Range: 2.5V ~ 6V compatibility
• Package Type: 28-SSOP surface mount form factor
• Peripheral Set: Brown-out detection, POR, PWM, WDT functionality
• Connectivity Protocols: I2C and SPI support
• Operating Temperature Range: 0°C ~ 70°C

The substitute part PIC16LC62A-04/SS meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC62A-04/SS is a direct functional equivalent to the PIC16LC62AT-04/SS. Both devices are ROHS3 compliant and carry identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and packaging format. The PIC16LC62AT-04/SS is classified as obsolete, while the PIC16LC62A-04/SS maintains active product status with higher inventory availability (3180 pieces versus 818 pieces). The PIC16LC62A-04/SS is supplied in tube packaging rather than tape and reel format.

For new designs or production continuity, the PIC16LC62A-04/SS is the appropriate selection. Both parts are suitable for applications requiring 8-bit microcontroller functionality with OTP program memory in legacy system support scenarios.

Frequently Asked Questions (FAQ)

Q: Can the PIC16LC62A-04/SS replace the PIC16LC62AT-04/SS in existing designs?

A: Yes. The PIC16LC62A-04/SS is electrically and mechanically equivalent. Both devices feature identical core processor architecture, memory configuration, I/O pin count, supply voltage range, operating temperature range, and peripheral functionality. The 28-SSOP package dimensions are identical.

Q: What is the difference between tape and reel packaging and tube packaging?

A: Tape and reel (TR) packaging is used for automated assembly processes, while tube packaging is used for manual handling and lower-volume applications. Both formats contain the same component. Selection depends on production methodology and assembly equipment compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the PIC16LC62AT-04/SS and PIC16LC62A-04/SS are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: Why is the PIC16LC62AT-04/SS classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle status. The PIC16LC62A-04/SS maintains active status and is the current production equivalent.

Q: Are there any electrical performance differences between these parts?

A: No. Both devices operate at 4MHz, support 2.5V to 6V supply voltage, and include identical peripheral sets (brown-out detection, POR, PWM, WDT). Functional performance is equivalent.
