ATF750LVC-15PI

Complex Programmable Logic Devices Overview

The ATF750LVC-15PI is a high-performance CMOS electrically-erasable complex programmable logic device (CPLD) based on the Atmel 750 architecture. It operates within a 3.0V to 5.5V supply range and features 22 logic pins, including 10 I/Os and 12 inputs. The device provides 42 array inputs, 20 sum terms, and 20 individually configurable D- or T-type flip-flops. With a maximum pin-to-pin delay of 15 ns at 3V operation, it supports advanced clocking options and programmable pin-keeper circuits for enhanced flexibility in compact 24-pin packages.

Complex Programmable Logic Devices Feature Summary

• Superset of 22V10 architecture with 42 array inputs, 20 sum terms, and 20 flip-flops
• 15 ns maximum pin-to-pin delay at 3V operation; 10 ns at 5V operation
• Individually configurable D- or T-type registers with product term or direct input pin clocking
• Programmable pin-keeper circuits eliminate need for external pull-up resistors

Complex Programmable Logic Devices Applications

• Replacement for standard 22V10 PAL devices requiring higher density
• Complex state machine implementation in embedded systems
• Bus interface logic with bi-directional I/O capabilities
• Clock distribution and synchronization circuits

Complex Programmable Logic Devices Procurement Notes

Verify package type compatibility, as the -PI suffix denotes a Plastic Dual Inline Package (PDIP). Confirm RoHS compliance status if lead-free requirements are mandatory, noting that datasheet revisions indicate specific green package options. Ensure programming equipment supports the electrically-erasable technology and verify voltage levels match the 3.0V–5.5V operating range.

Complex Programmable Logic Devices Selection Notes

Select the -15 speed grade for designs requiring up to 15 ns propagation delay at 3V or 10 ns at 5V. Choose this device over lower-density PLDs when more than 10 registered outputs or complex feedback paths are needed. Consider the industrial temperature range (-40°C to +85°C) for harsh environments. Verify that the 24-pin PDIP footprint fits the target PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the ATF750LVC family, which utilizes Atmel's electrically-erasable EEPROM technology. It is architecturally compatible with the ATV750B series and shares software/hardware compatibility with existing Atmel design tools. The device represents an evolution of the classic 22V10 PLD form factor, offering significantly increased logic resources within the same physical package dimensions.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other ATF750LVC variants with different speed grades or packages, such as ATF750LVC-15JU (PLCC) or ATF750LVC-15SU (SOIC). For legacy 22V10 applications, this part serves as a drop-in logical upgrade. Verify that any substitute maintains the 3.0V–5.5V supply voltage tolerance and 24-pin configuration.
