ATMEGA88V-10PI Equivalent & Substitute Parts

Part Overview

The ATMEGA88V-10PI is an 8-bit AVR microcontroller manufactured by Microchip Technology, featuring 8KB FLASH program memory, 1KB RAM, and 512 bytes EEPROM. This device operates at 10MHz with a supply voltage range of 1.8V to 5.5V and includes integrated peripherals such as I2C, SPI, UART/USART connectivity, PWM, watchdog timer, and brown-out detection. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitution of the ATMEGA88V-10PI is determined by strict equivalence across the following critical parameters:

• Core Architecture: AVR processor family
• Memory Configuration: 8KB FLASH, 1KB RAM, 512 bytes EEPROM
• Operating Frequency: 10MHz
• Supply Voltage Range: 1.8V ~ 5.5V
• I/O Count: 23 pins
• Peripheral Set: I2C, SPI, UART/USART, PWM, WDT, brown-out detection
• Package Type: 28-DIP through-hole form factor
• Temperature Range: -40°C ~ 85°C

The ATMEGA88V-10PU meets all these criteria, differing only in packaging designation (PDIP vs. DIP nomenclature) and product status (Active vs. Obsolete), with no functional or electrical differences.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA88V-10PU is a direct functional equivalent to the ATMEGA88V-10PI. Both devices share identical electrical specifications, memory architecture, peripheral configuration, and package dimensions. The primary distinction is product lifecycle status: the ATMEGA88V-10PI is obsolete, while the ATMEGA88V-10PU maintains active production status. Both parts carry identical export classification (EAR99) and tariff codes (8542.31.0001). Selection of the ATMEGA88V-10PU is appropriate for new designs and ongoing procurement where component availability is a consideration.

Frequently Asked Questions (FAQ)

Q: Are ATMEGA88V-10PI and ATMEGA88V-10PU pin-compatible?

A: Yes. Both devices use the 28-DIP (0.300", 7.62mm) package with identical pinout and electrical characteristics. Direct socket substitution is possible without circuit modification.

Q: What is the difference between the PI and PU package designations?

A: The designations refer to packaging variants within the 28-DIP form factor. Both are through-hole packages with equivalent mechanical and electrical properties. The difference is nomenclature only and does not affect functional compatibility.

Q: Can ATMEGA88V-10PU replace ATMEGA88V-10PI in existing designs?

A: Yes. The ATMEGA88V-10PU is electrically and mechanically equivalent. No design changes are required for substitution.

Q: Why is the ATMEGA88V-10PI listed as obsolete?

A: Product obsolescence reflects end-of-life status from the manufacturer. The ATMEGA88V-10PU remains in active production and is the recommended source for new component procurement.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts share identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications, indicating equivalent regulatory and export status.

Q: What memory and I/O specifications must be matched for substitution?

A: Substitutes must maintain 8KB FLASH, 1KB RAM, 512 bytes EEPROM, 23 I/O pins, and 10MHz operating frequency. Any deviation in these parameters indicates a non-equivalent device.
