Substitute Part Grouping Explanation

Substitution of the ATTINY45V-10PI is determined by strict equivalence across the following critical parameters:

• Core Architecture: AVR processor family
• Memory Configuration: 4KB FLASH, 256 bytes EEPROM, 256 bytes RAM
• Operating Frequency: 10MHz
• Supply Voltage Range: 1.8V ~ 5.5V
• I/O Count: 6 pins
• Package Type: 8-PDIP through-hole
• Peripheral Set: Brown-out Detect/Reset, POR, PWM, WDT, USI connectivity, 4x10-bit A/D converters

The ATTINY45V-10PU meets all substitution criteria as a direct equivalent, differing only in packaging format (bulk vs. standard) and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The ATTINY45V-10PU is a direct functional equivalent to the ATTINY45V-10PI. Both devices share identical electrical specifications, memory configurations, and peripheral sets. The primary distinction is product status: the ATTINY45V-10PI is obsolete, while the ATTINY45V-10PU remains in active production. For new designs or component replenishment, the ATTINY45V-10PU is the appropriate selection due to its active status and assured long-term availability. Both parts comply with the same ECCN (EAR99) and HTSUS (8542.31.0001) classifications.

Frequently Asked Questions (FAQ)

Q: Can ATTINY45V-10PU directly replace ATTINY45V-10PI in existing designs?

A: Yes. Both parts are electrically and functionally identical. The 8-PDIP package pinout, memory organization, operating voltage range, and peripheral configuration are identical. No circuit modifications are required.

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

A: The PI designation indicates standard packaging, while PU indicates bulk packaging. Both use the same 8-PDIP through-hole package format with identical pin spacing (0.300", 7.62mm).

Q: Why is the ATTINY45V-10PI listed as obsolete?

A: Microchip Technology has discontinued this part number. The ATTINY45V-10PU, manufactured by Atmel (now part of Microchip), remains in active production and serves as the current equivalent.

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

A: Both parts share identical ECCN and HTSUS classifications. RoHS compliance status and REACH applicability should be verified with current datasheets, as these may change with manufacturing updates.

Q: What inventory considerations apply to these substitutes?

A: The ATTINY45V-10PI has 720 units in stock (obsolete status). The ATTINY45V-10PU has 3918 units in stock with active product status, ensuring continued availability for procurement.
