ATF16V8BQL-15JI

Overview

The ATF16V8BQL-15JI is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It utilizes CMOS Flash memory technology and features 8 macrocells with 20 I/O pins in a PLCC-20 package. The device operates at a maximum propagation delay of 15 ns, supporting clock frequencies up to 45 MHz. It functions within an industrial temperature range of -40°C to +85°C using a 5V power supply. Standby current is typically 5 mA, while active current reaches 20 mA at 15 MHz.

Feature Summary

• High-speed performance with 15 ns max pin-to-pin delay
• Low-power standby mode with 5 mA typical current consumption
• Industrial temperature range (-40°C to +85°C)
• Reprogrammable Flash architecture with 100 erase/write cycles

Applications

• Direct replacement for 16R8 family PAL devices
• Complex logic function implementation in embedded systems
• State machine initialization and control circuits

Procurement Notes

Verify the specific ordering suffix 'JI' corresponds to the PLCC-20 package and Industrial temperature grade as defined in the official Microchip/Atmel ordering guide. Confirm that the required speed grade (15 ns) meets system timing constraints. Ensure programming equipment supports the ATF16V8BQL Flash architecture and voltage levels.

Selection Notes

Select this component when low standby power is critical alongside industrial temperature operation. The 'QL' suffix indicates the low-power variant compared to standard B or BQ versions. Ensure the design accommodates the 5V supply tolerance of ±10% for industrial applications. Verify that the 8 macrocell capacity suffices for the target logic complexity without requiring larger PLDs.

Part Context

This part belongs to the ATF16V8BQL series, which offers enhanced power efficiency over the standard ATF16V8B. The 'J' denotes the PLCC surface-mount package, while 'I' specifies the industrial temperature rating. It is part of the broader EEPLD family designed to emulate legacy 20-pin PAL architectures.

Replacement Considerations

Publicly confirmed substitutes include other ATF16V8BQL variants with different speed grades (e.g., ATF16V8BQL-10JI, ATF16V8BQL-25JI) or packages (e.g., ATF16V8BQL-15PI for PDIP). Cross-family replacements like ATF16V8CZ require verification of pin compatibility and power specifications.
