ATF16LV8C-15PI

Overview

The ATF16LV8C-15PI is a high-performance Electrically Erasable CMOS Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features an industry-standard architecture emulating 20-pin PALs, with eight macrocells and 20 I/O pins in a 20-PDIP package. The device operates within a voltage range of 3.0V to 5.5V and supports commercial temperature ranges from 0°C to 70°C. Key electrical parameters include a maximum pin-to-pin propagation delay of 15 ns, a typical standby current of 100 nA, and a programmable power-down mode reducing supply current to less than 5 µA. Inputs are 5V tolerant, and the device utilizes advanced Flash technology for reprogrammability.

Feature Summary

• High-speed performance with a maximum 15 ns pin-to-pin delay
• Ultra-low power consumption featuring 100 nA typical standby current and <5 µA power-down mode
• CMOS and TTL compatible inputs and outputs with 5V tolerant I/O pins
• Advanced Flash memory technology providing 100% testing and 2,000V ESD protection

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs
• Implementation of highly complex logic functions using three configurable modes of operation
• State machine initialization utilizing power-up reset features

Procurement Notes

Verify that the specific ordering code matches the required industrial or commercial temperature range, as suffixes determine operational limits. Confirm package type compatibility, noting that 'P' indicates a 20-lead PDIP. Ensure design margins account for the specified DC characteristics, including input leakage and output drive currents at the target supply voltage.

Selection Notes

Select the ATF16LV8C-15PI when a 15 ns speed grade is required for commercial applications (0°C to 70°C). Choose this variant over the -10JI or -10JC if lower speed is acceptable but cost or availability favors the 15 ns option. Verify that the 20-PDIP package fits the board layout constraints compared to surface mount alternatives like SOIC or TSSOP.

Part Context

This component belongs to the ATF16LV8C series of EEPLDs, which utilize Atmel's electrically-erasable Flash memory technology. The series offers speeds down to 10 ns and includes green package options compliant with RoHS standards. The device is part of a superset of generic architectures designed for easy software tool integration and direct replacement of legacy PAL devices.

Replacement Considerations

ATF16LV8C-15PC is a similar commercial variant in a PDIP package.
