ATMEGA162L-8PI Equivalent & Substitute Parts

Part Overview

The ATMEGA162L-8PI is an 8-bit AVR microcontroller manufactured by Microchip Technology, featuring 16KB FLASH program memory, 1KB RAM, and 512 bytes EEPROM. This device operates at 8MHz with a supply voltage range of 2.7V to 5.5V and is housed in a 40-DIP package. The ATMEGA162L-8PI is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

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

Core Architecture: AVR processor family
Memory Configuration: 16KB FLASH, 1KB RAM, 512 bytes EEPROM
Operating Frequency: 8MHz
I/O Count: 35 pins
Package Type: 40-DIP through-hole form factor
Connectivity & Peripherals: EBI/EMI, SPI, UART/USART, Brown-out Detect/Reset, POR, PWM, WDT
Operating Temperature Range: -40°C ~ 85°C
Mounting Configuration: Through Hole

The ATMEGA162V-8PU qualifies as a direct substitute based on identical core specifications, memory architecture, I/O configuration, package format, and peripheral set. Voltage supply range differences do not preclude substitution when operating conditions remain within the overlapping specification window.

Engineering Selection Recommendations

The ATMEGA162V-8PU is a direct functional equivalent to the ATMEGA162L-8PI. Both devices share identical core architecture, memory configuration, I/O specifications, and peripheral functionality. The primary distinction is product status: the ATMEGA162L-8PI is obsolete, while the ATMEGA162V-8PU remains in active production.

The ATMEGA162V-8PU offers an extended minimum supply voltage specification (1.8V versus 2.7V), providing additional operational flexibility in low-voltage applications. This extended range does not compromise compatibility with systems designed for the ATMEGA162L-8PI operating window.

Both devices carry identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications. The ATMEGA162V-8PU is available in bulk packaging with higher inventory levels, supporting both replacement and new design applications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both devices are pin-compatible 40-DIP packages with identical core specifications, memory architecture, I/O configuration, and peripheral set. No circuit modifications are required for direct substitution.

Q: What is the difference between the ATMEGA162L-8PI and ATMEGA162V-8PU?

A: The devices are functionally equivalent. The primary differences are manufacturer designation (Microchip Technology versus Atmel), product status (obsolete versus active), and supply voltage minimum specification (2.7V versus 1.8V). The ATMEGA162V-8PU supports operation at lower supply voltages.

Q: Are there any package or pinout differences?

A: No. Both devices use identical 40-DIP through-hole packaging with 0.600" (15.24mm) body width and matching pinout configurations.

Q: What is the inventory status of these parts?

A: The ATMEGA162L-8PI has 1120 units in stock. The ATMEGA162V-8PU has 2081 units in stock, providing greater availability for immediate procurement.

Q: Do these devices have the same operating temperature range?

A: Yes. Both devices operate across -40°C to 85°C, supporting industrial and extended temperature applications.

Q: Are there compliance or certification differences?

A: Both devices carry identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications. RoHS compliance status differs: ATMEGA162L-8PI is RoHS non-compliant; ATMEGA162V-8PU status is not specified in provided data.
