ATF16V8BQL-15JC

Overview

The ATF16V8BQL-15JC is a high-performance CMOS electrically-erasable programmable logic device (EEPLD) utilizing Flash memory technology. It features eight macrocells with dedicated product terms, supporting registered, complex, and simple modes for PAL emulation. The -15 speed grade provides a maximum pin-to-pin delay of 15 ns and a clock-to-output delay of 10 ns. Designed for commercial applications, it operates within a 0°C to 70°C temperature range at a nominal 5V supply. The device offers low standby current of 5 mA and active current of 20 mA at 15 MHz, ensuring energy efficiency in digital logic implementations.

Feature Summary

• Eight macrocells with flexible configuration for registered, complex, or simple logic modes
• Maximum 15 ns pin-to-pin propagation delay and 10 ns clock-to-output delay
• Low power consumption: 5 mA standby current and 20 mA active current at 15 MHz
• CMOS and TTL compatible inputs/outputs with internal pull-up resistors

Applications

• Direct replacement for 16R8 family and other 20-pin combinatorial PLDs
• Digital logic control circuits requiring reprogrammability
• State machine implementation with power-up reset initialization
• PCI-compliant interface logic design

Procurement Notes

Verify the ordering suffix 'JC' corresponds to the 20-lead Plastic J-leaded Chip Carrier (PLCC) package and Commercial temperature range (0°C to 70°C). Confirm that the -15 speed grade meets the specific timing requirements of the target circuit, as this variant specifies a 15 ns maximum delay. Ensure programming equipment supports the ATF16V8BQL series Flash architecture.

Selection Notes

Select the ATF16V8BQL-15JC when low power consumption is critical, as it draws significantly less current than standard ATF16V8B variants. Choose this part if the application requires a surface-mount PLCC package and operates within the commercial temperature range. For industrial temperatures (-40°C to 85°C), the -15JI variant must be selected instead. Verify that the 15 ns speed grade satisfies the system's maximum clock frequency constraints.

Part Context

This component belongs to the ATF16V8B(QL) family of EEPLDs, which are designed to emulate industry-standard 20-pin PAL devices. The 'QL' suffix denotes the low-power Flash variant, offering reduced standby and active currents compared to the standard B and BQ versions. The family supports universal architecture compatibility with various development software tools like ABEL and CUPL.

Replacement Considerations

Public confirmed substitute part numbers include ATF16V8BQL-15JI for industrial temperature operation and ATF16V8BQL-15PC for PDIP packaging. Standard ATF16V8B-15JC may serve as a functional alternative if higher power consumption is acceptable. Direct replacement for 16R8 series devices is supported via compiler mode selection.
