ATF16V8B-10SC

Overview

The ATF16V8B-10SC is a high-performance CMOS electrically-erasable programmable logic device (PLD) manufactured by Microchip Technology. It utilizes Atmel’s Flash memory technology and features eight macrocells with eight product terms each. The component operates at a maximum pin-to-pin delay of 10 ns, with an input setup time of 7.5 ns and clock-to-output delay of 7 ns. Designed for commercial applications, it functions within a temperature range of 0°C to 70°C using a 5V ± 5% power supply. The device supports both CMOS and TTL compatible I/O levels and includes internal pull-up resistors.

Feature Summary

• High-speed performance with 10 ns maximum propagation delay
• Reprogrammable Flash architecture supporting 100 erase/write cycles
• Emulates industry-standard 20-pin PAL devices like the 16R8 family
• Integrated 2,000V ESD protection and 200 mA latchup immunity

Applications

• Industrial control systems requiring logic emulation
• Replacement for obsolete 20-pin combinatorial PLDs
• Complex digital logic design in commercial electronics

Procurement Notes

Verify package type 'S' corresponds to the 20-lead Plastic Gull-wing Small Outline (SOIC) format. Confirm the suffix indicates Commercial temperature range (0°C to 70°C). Ensure programming hardware supports standard PLD JEDEC file formats for Flash-based reprogramming.

Selection Notes

Select this part when a 10 ns speed grade is required for commercial environments. Compare standby current specifications against low-power variants like the BQL series if power consumption is critical. Ensure the application does not require industrial temperature ratings (-40°C to 85°C), which necessitate the 'I' suffix variant.

Part Context

This component belongs to the ATF16V8B family, which offers three speed grades: 7.5 ns, 10 ns, and 15 ns. The -10SC designation specifically identifies the 10 ns speed bin packaged in SOIC for commercial use. The family provides flexibility through Registered, Complex, and Simple operating modes configurable via software compilers.

Replacement Considerations

Direct architectural replacement for 16R8, 16RP8, 16R6, and 16RP8 PAL devices. Verify pin compatibility for 20-pin DIP, SOIC, or PLCC footprints depending on the target legacy component.
