ATF16V8C-7XU

Overview

The ATF16V8C-7XU is a high-performance electrically-erasable programmable logic device (EE PLD) utilizing Atmel flash technology. It features a maximum pin-to-pin delay of 7.5ns and operates within the industrial temperature range of -40°C to +85°C. The device supports a pin-controlled power-down mode with current consumption below 100μA. It provides eight outputs, each allocated eight product terms, and includes CMOS/TTL compatible I/Os with pin-keeper circuits. The component is housed in a 20-lead TSSOP package.

Feature Summary

• High-speed EE PLD with 7.5ns max pin-to-pin delay
• Pin-controlled power-down mode reduces supply current to <100μA
• CMOS and TTL compatible inputs/outputs with internal pin-keeper circuits
• Industrial temperature range (-40°C to +85°C) with 5V ±10% supply tolerance

Applications

• Replacement for 20-pin PAL devices such as 16R8, 16L8, and 10L8 families
• Complex logic function implementation requiring reprogrammability
• Systems requiring low-power standby states via pin-controlled power-down
• PCI compliant circuit designs

Procurement Notes

Verify that the ordering suffix 'X' corresponds to the 20-lead TSSOP package and 'U' indicates RoHS compliance. Confirm the speed grade '-7' matches the required 7.5ns maximum propagation delay. Ensure the application environment falls within the specified industrial temperature range of -40°C to +85°C. Check that the design file configuration aligns with the selected macrocell modes if power-down functionality is utilized.

Selection Notes

Select this model when an industrial temperature rating is required alongside surface-mount packaging. The '-7' speed grade offers a balance between performance and power. Consider the pin-keeper feature if internal pull-up resistors are undesirable. Verify compiler software compatibility for the desired emulation mode (Registered, Complex, or Simple) to ensure proper architecture configuration during programming.

Part Context

This part belongs to the Atmel ATF16V8C family of universal architecture PLDs. It emulates standard 20-pin PAL devices while offering reprogrammability through flash memory. The 'C' designation indicates commercial-grade electrical specifications adapted for industrial use, while 'X' specifies the TSSOP package variant. The device replaces obsolete lead-based packages with green, RoHS-compliant options.

Replacement Considerations

Direct replacement for 16R8, 16L8, 16H8, 16P8, 10L8, 10H8, 10P8, 12L6, 12H6, 12P6, 14L4, 14H4, 14P4, 16L2, 16H2, and 16P2 PALs. Ensure the target system supports the specific voltage tolerances (5V ±10%) and timing requirements of the 7.5ns grade.
