ATF20V8BQL-15JU

Overview

The ATF20V8BQL-15JU is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 8 macrocells and 20 I/O pins in a 28-lead PLCC package. The device operates at a maximum propagation delay of 15 ns and supports a supply voltage range of 4.5 V to 5.5 V. It includes low-power standby options, internal pull-up resistors, and industrial temperature range support (-40°C to +85°C).

Feature Summary

• High-speed Electrically-Erasable Flash Technology with 15 ns max pin-to-pin delay.
• Industry-standard Architecture emulating many 24-pin PALs.
• Low Power Options: Standby current as low as 5 mA for BQL series.
• Industrial Temperature Range: -40°C to +85°C operation.

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 ordering suffix 'U' indicates a Pb/Halide-free/RoHS compliant green package option. Confirm the 'QL' suffix corresponds to the low-power variant with 5 mA standby current. Ensure the 'J' suffix matches the required 28-lead PLCC package type for your application.

Selection Notes

Select this part for applications requiring reprogrammability and low power consumption. The ATF20V8BQL offers significantly lower active and standby currents compared to standard ATF20V8B variants. Choose based on the required speed grade (15 ns) and package compatibility (PLCC-28).

Part Context

This component belongs to the ATF20V8B family of EEPLDs. It is designed to be a drop-in replacement for older PAL devices while offering modern reprogrammability via flash technology. The BQL variant specifically targets power-sensitive designs within the industrial temperature range.

Replacement Considerations

ATF20V8BQL-15JI serves as a direct functional substitute with identical electrical characteristics but potentially different packaging or compliance status depending on the specific suffix interpretation.
