ATF16V8BQ-10XC

Overview

The ATF16V8BQ-10XC is a high-performance CMOS electrically-erasable programmable logic device (PLD) utilizing Atmel Flash memory technology. It features eight macrocells and operates at a maximum pin-to-pin delay of 10 ns. The device supports a 5V supply with ±5% tolerance for commercial applications (0°C to 70°C). Key electrical characteristics include a standby current of 35 mA typical and an active current of 40 mA typical at 15 MHz. It offers 2,000V ESD protection, 200 mA latchup immunity, and 100 erase/write cycles.

Feature Summary

• Industry-standard architecture emulating many 20-pin PALs
• 7.5 ns setup time and 10 ns max pin-to-pin delay
• CMOS and TTL compatible inputs/outputs with internal pull-ups
• Reprogrammable Flash technology with 20-year data retention

Applications

• Industrial control systems requiring low-power PLD replacement
• Commercial logic design emulation for legacy 20-pin PAL devices
• Complex digital logic functions in power-limited applications

Procurement Notes

Verify the package type corresponds to the 'X' suffix, indicating a 20-lead TSSOP. Confirm the temperature range matches commercial requirements (0°C to 70°C) as industrial variants use different suffixes. Ensure programming equipment supports the specific Flash memory architecture and voltage levels defined in the datasheet specifications.

Selection Notes

Select this variant for designs requiring lower power consumption than the standard ATF16V8B while maintaining 10 ns speed. The TSSOP package is suitable for surface-mount applications. Compare standby current (35 mA) against the standard B series (55 mA) if power efficiency is critical. Ensure compiler software is configured for the appropriate macrocell mode (Registered, Complex, or Simple).

Part Context

This component belongs to the ATF16V8B family, which includes standard (B), low-power (BQ), and ultra-low-power (BQL) variants. The 'Q' suffix denotes the reduced power consumption profile. The '10' indicates the 10 ns speed grade, and 'XC' specifies the commercial temperature range and TSSOP package. This family provides a superset of generic architectures for direct replacement of 16R8 series devices.

Replacement Considerations

Direct replacements include other ATF16V8B-10 variants with different packages (e.g., ATF16V8B-10PC for PDIP, ATF16V8B-10SC for SOIC). For industrial temperature ranges, consider ATF16V8BQ-10XI. Standard ATF16V8B-10JC or -10PC can be used if higher power consumption is acceptable.
