ATF16V8BQL-15PC

Overview

The ATF16V8BQL-15PC is a high-performance CMOS electrically erasable programmable logic device (PLD) utilizing Atmel’s Flash memory technology. It features eight macrocells and operates at a maximum pin-to-pin delay of 15 ns. The device supports a 5V power supply with ±10% tolerance for industrial applications (-40°C to +85°C). Key electrical characteristics include a standby current of 5 mA typical and an active clocked current of 20 mA typical at 15 MHz. It offers 2,000V ESD protection, 200mA latchup immunity, and 100 erase/write cycles.

Feature Summary

• Emulates industry-standard 20-pin PAL devices with three configurable modes: Registered, Complex, and Simple.
• Low-power 'L' variant featuring automatic standby mode with 5 mA typical standby current.
• CMOS and TTL compatible inputs/outputs with internal pull-up resistors.
• Advanced Flash technology allowing reprogramming, 20-year data retention, and 100 erase/write cycles.

Applications

• Direct replacement for 16R8 family and other 20-pin combinatorial PLDs.
• Industrial control systems requiring low power consumption.
• Logic interface circuits in embedded systems.

Procurement Notes

Verify the ordering suffix 'PC' corresponds to the 20-lead Plastic Dual Inline Package (PDIP) as specified in the datasheet. Confirm that the component meets the required industrial temperature range specifications. Check for RoHS compliance status, as older manufacturing runs may differ from current production standards.

Selection Notes

Select this part when a low-power solution is required compared to the standard ATF16V8B or ATF16V8BQ variants. Ensure the design utilizes the specific pinout where Pin 1 serves as CLK and Pin 11 as OE in registered mode. Verify that the 15 ns speed grade meets the system timing requirements.

Part Context

This component belongs to the ATF16V8B(QL) series, which includes standard (B), low-power (BQ), and ultra-low-power (BQL) variants. The 'QL' suffix denotes the low-power version with enhanced sleep capabilities. The series provides a superset architecture compatible with legacy GAL and PAL designs.

Replacement Considerations

Publicly confirmed substitutes include ATF16V8B-15PC and ATF16V8BQ-15PC within the same package. These alternatives offer identical pinouts but differ in power consumption profiles; the BQL variant is specifically optimized for lower standby currents.
