ATF16V8BQ-10JC

Overview

The ATF16V8BQ-10JC 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 ± 5% supply voltage for commercial applications (0°C to 70°C). Key electrical characteristics include a typical standby current of 35 mA and an active current of 40 mA at 15 MHz. It offers 2,000V ESD protection, 200 mA latchup immunity, and 100 erase/write cycles with 20-year data retention.

Feature Summary

• Emulates industry-standard 20-pin PAL architectures including 16R8, 16L8, and 10L8 families.
• Supports Registered, Complex, and Simple modes for flexible logic configuration.
• Includes internal input and I/O pull-up resistors for known logic states.
• Provides 2,000V ESD protection and 200 mA latchup immunity.

Applications

• Industrial control systems requiring low-power PLD replacement.
• Commercial embedded logic functions compatible with TTL/CMOS interfaces.
• State machine initialization using power-up reset features.

Procurement Notes

Verify the package type corresponds to the 'JC' suffix, which indicates a 20-lead Plastic J-leaded Chip Carrier (PLCC). Confirm that the commercial temperature range (0°C to 70°C) meets system requirements, as industrial variants use different suffixes. Ensure programming hardware supports the specific Flash architecture and security fuse settings.

Selection Notes

Select this part when a 10 ns speed grade is required with reduced power consumption compared to the standard ATF16V8B. The BQ variant offers lower standby (35 mA) and active (40 mA) currents than the standard B series. Choose the PLCC package if surface mount installation is necessary for the target design.

Part Context

This component belongs to the ATF16V8B family, which includes standard (B), low-power (BQ), and ultra-low-power (BQL) variants. The ATF16V8BQ series specifically targets applications requiring moderate power savings while maintaining high-speed performance. It shares the same logical architecture and pinout compatibility as other members of the family.

Replacement Considerations

Direct architectural replacements include ATF16V8B-10JC for standard power or ATF16V8BQL-10JC for lower power if available. Verify that the substitute maintains the 10 ns delay specification and PLCC-20 package dimensions.
