Overview
The ATF16V8BQL-15XI is a high-performance CMOS electrically-erasable programmable logic device (PLD) manufactured by Microchip Technology. It utilizes Atmel’s Flash memory technology and features eight macrocells with registered, complex, or simple modes of operation. The -15 speed grade provides a maximum pin-to-pin delay of 15 ns. Designed for industrial applications, it operates within a temperature range of -40°C to +85°C at a supply voltage of 5V ± 10%. The device is housed in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package.
Feature Summary
- Industrial temperature range (-40°C to +85°C) with 5V ± 10% supply tolerance
- Low standby current consumption of 5 mA typical
- Reprogrammable Flash architecture supporting 100 erase/write cycles
- Emulates industry-standard 20-pin PAL devices
Applications
- Direct replacement for 16R8 family PLDs
- Industrial control systems requiring low power
- Complex logic functions with registered outputs
Procurement Notes
Verify the ordering suffix 'I' confirms the Industrial temperature rating (-40°C to +85°C). Confirm the 'X' suffix corresponds to the 20-lead PLCC package. Ensure programming equipment supports the specific ATF16V8BQL Flash architecture and voltage requirements.
Selection Notes
Select this variant over commercial versions when operating environments exceed 70°C. The BQL suffix indicates low-power standby characteristics suitable for battery-operated or power-sensitive designs. Verify that the 20-lead PLCC footprint matches the target PCB layout constraints.
Part Context
This component belongs to the ATF16V8BQL series, which offers lower power consumption compared to the standard ATF16V8B and ATF16V8BQ variants. The series maintains architectural compatibility with legacy PAL devices while providing modern reprogrammability via Flash technology.
