ATF20V8B-10JU

Overview

The ATF20V8B-10JU is a high-performance Electrically-Erasable Programmable Logic Device (EE PLD) manufactured by Microchip Technology. It features 8 macrocells and operates at a maximum pin-to-pin delay of 10 ns with a clock period of 12 ns. The device utilizes advanced Flash technology for reprogrammability and is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. It supports industrial temperature ranges (-40°C to +85°C) and functions with a 5V supply voltage.

Feature Summary

• Industry-standard architecture emulating many 24-pin PALs
• High-speed operation with 10 ns maximum propagation delay
• Advanced Flash memory technology allowing 100 erase/write cycles
• CMOS and TTL compatible inputs and outputs

Applications

• Direct replacement for 20R8 family and most 24-pin combinatorial PLDs
• Complex logic function realization using registered, complex, or simple modes
• State machine initialization with power-up reset feature

Procurement Notes

Verify the component is an EE PLD with 8 macrocells and 10 ns speed grade. Confirm the package is 28-lead PLCC (28J). Ensure the suffix 'U' indicates RoHS compliance and industrial temperature range availability as per ordering information.

Selection Notes

Select this part for applications requiring direct replacement of 24-pin PALs. Choose the -10 speed grade for 10 ns performance. Consider lower power variants like ATF20V8BQ or ATF20V8BQL if power consumption is a critical constraint, noting their different standby and active current specifications.

Part Context

This device belongs to the ATF20V8B family of high-performance EE PLDs. It offers multiple operating modes (Registered, Complex, Simple) to emulate various PAL devices. The family includes commercial and industrial temperature options, with the -JU variant specifically designated for industrial use with Green package compliance.

Replacement Considerations

ATF20V8B-10JC is the commercial temperature equivalent. ATF20V8B-7JU offers faster 7.5 ns performance. ATF20V8BQ-10JU and ATF20V8BQL-10JU provide lower power consumption options.
