ATF16LV8C-15SC

Overview

The ATF16LV8C-15SC is a low-voltage, high-speed Flash Programmable Logic Device (PLD) belonging to the Atmel ATF16V8 family. It operates at supply voltages as low as 3.0 V and features a maximum propagation delay of 15 ns. The device utilizes CMOS technology and contains 250 gates with 8 macro cells, supporting up to 8 I/O lines. It is housed in a 20-pin Small Outline Package (SOIC). Key electrical characteristics include asynchronous operation and support for In-System Programming (ISP), allowing configuration updates without removal from the circuit board.

Feature Summary

• Low-voltage operation with a 3.0 V supply capability
• High-speed performance with 15 ns maximum propagation delay
• Flash memory architecture enabling non-volatile storage and ISP
• PAL-type logic structure with 8 macro cells and 8 I/Os

Applications

• General-purpose digital logic replacement
• Address decoding and chip select generation
• Bus protocol conversion
• State machine implementation in embedded systems

Procurement Notes

Verify the specific suffix 'SC' corresponds to the 20-pin SOIC package and lead-free status if required by assembly specifications. Confirm RoHS compliance status through official Microchip/Atmel documentation, as historical variants may differ. Ensure the design supports the 3.0 V operating range if replacing older 5 V versions.

Selection Notes

Select this component when a low-power, non-volatile PLD is needed for designs requiring 3.0 V operation. The 15 ns speed is suitable for moderate-frequency digital logic applications. Compare against the standard 5 V ATF16V8B series if voltage compatibility allows, noting that the LV variant offers reduced power consumption.

Part Context

This part is part of the ATF16V8 family of Flash PLDs, which replaced earlier EEPROM-based GALs. The 'LV' designation indicates Low Voltage operation, while '15' denotes the 15 ns speed grade. The 'C' typically refers to commercial temperature range, and 'SC' identifies the specific package type.

Replacement Considerations

Direct pin-compatible replacements within the same family include the ATF16V8B-15PC (5 V version) or other ATF16V8 variants with matching speed grades. Verify voltage levels before substitution to avoid damage to downstream components.
