ATF16V8B-15SU

Overview

The ATF16V8B-15SU is a high-performance CMOS Electrically-Erasable Programmable Logic Device (EE PLD) manufactured by Microchip Technology. It utilizes Atmel's Flash memory technology and operates within an industrial temperature range of -40°C to +85°C. The device features 8 macrocells, 10 inputs, and 8 I/O pins in a 20-lead SOIC package. Key electrical parameters include a maximum propagation delay of 15 ns, a supply voltage of 5.0V ± 10%, and a standby current of up to 80 mA.

Feature Summary

• Industry-standard architecture emulating many 20-pin PALs
• High-speed operation with 15 ns maximum pin-to-pin delay
• CMOS and TTL compatible inputs and outputs with internal pull-up resistors
• Advanced Flash technology allowing reprogramming with 100 erase/write cycles

Applications

• Industrial control systems requiring programmable logic
• Direct replacement for legacy 16R8 family and other 20-pin combinatorial PLDs
• Complex logic function implementation using registered, complex, or simple modes

Procurement Notes

Verify the specific ordering suffix 'SU' corresponds to the 20-lead SOIC package variant as listed in the official datasheet. Confirm that the component meets RoHS compliance standards if required by the application. Ensure compatibility with standard PLD programmers for programming and erasing operations.

Selection Notes

Select this model when a 15 ns speed grade is required for industrial environments (-40°C to +85°C). The ATF16V8B-15SU provides a surface-mount alternative to through-hole packages like PDIP or PLCC while maintaining identical logical functionality and pinout compatibility with standard 20-pin PLD footprints.

Part Context

This part belongs to the ATF16V8B series of SPLDs. It is designed to replace obsolete PAL devices and offers flexibility through three configurable modes: Registered, Complex, and Simple. The series supports direct software configuration via tools like Atmel WinCUPL to emulate various PAL architectures.

Replacement Considerations

The ATF16V8B-15SU can directly replace most 20-pin combinatorial PLDs and 16R8 family devices. Ensure that the target application does not require the low-power standby features specific to the BQL variant, as the standard B version has higher standby current.
