ATF16V8BQL-15XC

Overview

The ATF16V8BQL-15XC is a high-performance CMOS electrically-erasable programmable logic device (PLD) utilizing Atmel’s Flash memory technology. It features eight macrocells and supports three operational modes: registered, complex, and simple. The -15 speed grade provides a maximum pin-to-pin delay of 15 ns with a typical standby current of 5 mA. Operating at 5V ± 10%, it is available in industrial temperature ranges (-40°C to +85°C). The XC suffix indicates the TSSOP surface-mount package.

Feature Summary

• Eight macrocells with flexible configuration for registered, complex, or simple logic modes
• Low-power BQL variant with 5 mA typical standby current
• Advanced Flash technology allowing 100 erase/write cycles and 20-year data retention
• CMOS/TTL compatible inputs/outputs with internal pull-up resistors

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs
• Industrial control systems requiring low power consumption
• PCI-compliant digital logic applications
• State machine initialization and sequential logic design

Procurement Notes

Verify that the specific ordering code matches the required package type, as the ATF16V8BQL series includes multiple packages. Confirm the temperature range designation corresponds to the application environment. Check for RoHS compliance status if lead-free requirements are mandatory for the assembly process.

Selection Notes

Select the ATF16V8BQL variant over standard B or BQ versions when system power budgets require lower standby currents, specifically the 5 mA typical value. Ensure the design utilizes the TSSOP footprint if the XC suffix is selected. Verify compiler software compatibility for automatic mode selection based on register and output enable usage.

Part Context

This component belongs to the ATF16V8B(QL) family of high-performance EEPLDs. The 'QL' suffix denotes the low-power version with reduced supply current compared to the standard B and BQ variants. The 'XC' suffix specifies the 20-lead Plastic Thin Shrink Small Outline (TSSOP) package format.

Replacement Considerations

The device architecture allows direct replacement of the 16R8 family and many 20-pin PAL devices. Specific emulation JEDEC files are available for devices such as 16R8, 16L8, and 10L8 through appropriate compiler software configuration.
