Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT90S8515-8PI is determined by strict alignment of the following critical parameters:

• Core Architecture: AVR processor family
• Memory Configuration: 8KB FLASH, 512 x 8 EEPROM, 512 x 8 RAM
• Operating Frequency: 8MHz
• Package Form Factor: 40-DIP through-hole
• Connectivity Interfaces: SPI and UART/USART support
• Peripheral Feature Set: Brown-out detection, POR, PWM, WDT
• Operating Temperature Range: -40°C ~ 85°C

The ATMEGA8515L-8PU meets these substitution criteria. Both devices share identical memory architecture, clock frequency, package footprint, and core peripheral functionality. Voltage supply range differences and I/O count variations are secondary considerations that do not preclude functional substitution in applications designed for the AT90S8515-8PI.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA8515L-8PU is a direct functional substitute for the AT90S8515-8PI. Both devices are classified as obsolete products from Microchip Technology and share identical core memory architecture, clock frequency, and peripheral feature sets.

The ATMEGA8515L-8PU offers improved compliance status: it is ROHS3 compliant, whereas the AT90S8515-8PI is RoHS non-compliant. The substitute part also supports an extended voltage supply range (2.7V ~ 5.5V versus 4V ~ 6V) and provides three additional I/O pins (35 versus 32), along with EBI/EMI connectivity support.

For applications requiring strict adherence to modern environmental and regulatory standards, the ATMEGA8515L-8PU is the preferred selection. Both parts maintain identical 40-DIP package geometry, ensuring direct mechanical and electrical compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the ATMEGA8515L-8PU directly replace the AT90S8515-8PI in existing designs?

A: Yes. Both devices share identical 40-DIP package footprints, core memory configurations (8KB FLASH, 512 x 8 EEPROM, 512 x 8 RAM), 8MHz operating frequency, and peripheral feature sets. Direct PCB substitution is supported.

Q: What are the key differences between these parts?

A: The ATMEGA8515L-8PU operates across a wider voltage supply range (2.7V ~ 5.5V versus 4V ~ 6V), provides three additional I/O pins (35 versus 32), includes EBI/EMI connectivity, and meets ROHS3 compliance standards. The AT90S8515-8PI is RoHS non-compliant.

Q: Are there any connectivity or peripheral differences?

A: Both parts support SPI and UART/USART interfaces. The ATMEGA8515L-8PU additionally supports EBI/EMI. Both include identical peripheral features: brown-out detection, power-on reset, PWM, and watchdog timer.

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

A: Yes. Both the AT90S8515-8PI and ATMEGA8515L-8PU operate across -40°C to 85°C.

Q: What is the significance of the RoHS compliance difference?

A: The ATMEGA8515L-8PU meets ROHS3 compliance standards, making it suitable for applications subject to modern environmental regulations. The AT90S8515-8PI is RoHS non-compliant and may not meet procurement requirements for regulated industries or markets.
