ATF20V8B-10PC

Overview

The ATF20V8B-10PC is a high-performance electrically-erasable programmable logic device (EE PLD) manufactured by Microchip Technology. It utilizes advanced Flash memory technology and features 8 macrocells with a maximum pin-to-pin propagation delay of 10 ns. The device operates at a 5V supply voltage and supports commercial temperature ranges from 0°C to 70°C. It is housed in a 24-lead Plastic Dual Inline Package (PDIP). Key electrical characteristics include a standby current of up to 80 mA and an active current of up to 90 mA.

Feature Summary

• Industry-standard architecture emulating many 24-pin PALs
• High-speed Electrically-erasable Programmable Logic with 10 ns max delay
• CMOS and TTL compatible inputs and outputs
• Input and I/O pull-up resistors for known states

Applications

• Direct replacement for 20R8 family devices
• Replacement for most 24-pin combinatorial PLDs
• Logic functions requiring registered, complex, or simple modes

Procurement Notes

Verify the specific ordering code ATF20V8B-10PC against the manufacturer's official documentation to confirm package type and speed grade. Ensure compatibility with existing programming hardware and software tools as specified in the Configurable Logic Databook. Check for any obsolete part notifications or last-time buy dates associated with this component variant.

Selection Notes

Select the ATF20V8B-10PC when a 10 ns speed grade is required for commercial applications within the 0°C to 70°C range. Consider the ATF20V8BQ or ATF20V8BQL variants if lower power consumption is a priority, as they offer reduced standby and active currents compared to the standard ATF20V8B series.

Part Context

The ATF20V8B belongs to the ATF20V8B(Q)(L) family of high-performance EE PLDs. This family includes variants with different speed grades (-7, -10, -15, -25) and power options (standard, Q, QL). The device is designed to replace older PAL architectures while offering reprogrammability and enhanced reliability through CMOS Flash technology.

Replacement Considerations

The ATF20V8B can directly replace the 20R8 family and most 24-pin combinatorial PLDs. When replacing specific PAL devices, ensure the compiler mode (Registered, Complex, or Simple) matches the original device's functionality.
