ATF16V8B-10PC

Overview

The ATF16V8B-10PC 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 parameters include a standby current of 55 mA typical, input/output pull-up resistors, and 2000V ESD protection. It emulates industry-standard 20-pin PAL architectures and offers registered, complex, and simple modes.

Feature Summary

• Emulates many 20-pin PALs with three configurable modes: Registered, Complex, and Simple.
• High-speed performance with a maximum 10 ns pin-to-pin propagation delay.
• Advanced Flash technology enabling reprogrammability, 20-year data retention, and 100 erase/write cycles.
• CMOS and TTL compatible inputs/outputs with integrated internal pull-up resistors.

Applications

• Direct replacement for legacy 16R8 family and other 20-pin combinatorial PLDs.
• Industrial control systems requiring reliable logic emulation.
• Complex digital logic design utilizing registered or combinatorial output configurations.

Procurement Notes

Verify the specific speed grade (-10) and package type (PDIP-20) against project requirements. Confirm that the commercial temperature range (0°C to 70°C) aligns with the operating environment. Ensure programming equipment supports the ATF16V8B architecture and Flash memory interface. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a direct architectural substitute for standard 20-pin PAL devices is required. The -10 speed grade provides 10 ns delay suitable for moderate-frequency applications. Consider the BQ or BQL variants if lower power consumption is necessary, as they offer reduced standby currents compared to the standard ATF16V8B.

Part Context

This part belongs to the ATF16V8B series, which includes low-power variants like ATF16V8BQ and ATF16V8BQL. The series is designed to replace obsolete GAL and PAL devices while offering reprogrammability through Flash technology. The PDIP-20 package ensures compatibility with standard through-hole mounting techniques used in legacy designs.

Replacement Considerations

The ATF16V8B-10PC can directly replace devices such as the GAL16V8, G16V8, and P16V8 families when configured appropriately via software compilers. Ensure that the target application utilizes the same pinout and logic density constraints supported by the eight macrocell architecture.
