Substitute Part Grouping Explanation

Substitution of the ATMEGA162L-8PC is determined by strict equivalence across the following critical parameters:

• Core Architecture: AVR processor family
• Memory Configuration: 16KB FLASH, 1KB RAM, 512 bytes EEPROM
• I/O Count: 35 I/O pins
• Connectivity Interfaces: EBI/EMI, SPI, UART/USART
• Peripheral Set: Brown-out Detect/Reset, POR, PWM, WDT
• Package Type: 40-DIP form factor
• Pin Compatibility: Identical pinout required

The ATMEGA162V-8PU qualifies as a direct substitute based on matching all core functional parameters and package specifications. Differences in voltage supply range and operating temperature represent extended operational capabilities rather than functional incompatibility.

Engineering Selection Recommendations

The ATMEGA162V-8PU is the qualified substitute for the ATMEGA162L-8PC based on functional equivalence and active product status. The ATMEGA162V-8PU maintains identical core specifications, memory configuration, I/O architecture, and package form factor. The substitute part offers extended voltage supply range (1.8V minimum versus 2.7V) and expanded operating temperature range (-40°C to 85°C versus 0°C to 70°C), providing greater operational flexibility for diverse application environments. Both parts comply with identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications. Selection of the ATMEGA162V-8PU eliminates obsolescence risk while maintaining full functional compatibility with existing ATMEGA162L-8PC designs.

Frequently Asked Questions (FAQ)

Q: Can the ATMEGA162V-8PU directly replace the ATMEGA162L-8PC in existing designs?

A: Yes. Both devices share identical core architecture, memory configuration, I/O count, connectivity interfaces, and 40-DIP package specifications. Pin-for-pin compatibility is maintained.

Q: What are the differences between these two parts?

A: The primary differences are product status and operational ranges. The ATMEGA162L-8PC is obsolete; the ATMEGA162V-8PU is active. The ATMEGA162V-8PU supports lower minimum supply voltage (1.8V versus 2.7V) and wider operating temperature range (-40°C to 85°C versus 0°C to 70°C).

Q: Are there any compatibility concerns with the 40-DIP package?

A: No. Both parts use identical 40-DIP (0.600", 15.24mm) through-hole packaging. PCB layouts and socket compatibility remain unchanged.

Q: Does the extended temperature range of the ATMEGA162V-8PU affect circuit design?

A: No design modifications are required. The extended range represents additional operational capability. Existing designs operating within 0°C to 70°C will function identically on both parts.

Q: What is the significance of the voltage supply range difference?

A: The ATMEGA162V-8PU minimum supply voltage of 1.8V provides flexibility for low-power applications. The ATMEGA162L-8PC minimum of 2.7V is a subset of this range. Designs operating at 2.7V or higher are fully compatible with both parts.
