ATF16V8B-10SI

Overview

The ATF16V8B-10SI is a high-performance CMOS electrically-erasable programmable logic device (PLD) manufactured by Microchip Technology. It utilizes Atmel’s Flash memory technology and features an industry-standard architecture that emulates many 20-pin PALs. The device operates at a maximum pin-to-pin delay of 10 ns with a clock-to-output delay of 7 ns. It includes eight macrocells, supports three operational modes (registered, complex, simple), and provides CMOS/TTL compatible inputs and outputs with internal pull-up resistors. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C using a 5V ± 10% power supply.

Feature Summary

• High-speed performance with 10 ns maximum input-to-output propagation delay
• Flash-based reprogrammable architecture with 100 erase/write cycles and 20-year data retention
• Industrial temperature rating (-40°C to +85°C) with 5V ± 10% supply tolerance
• Compatible with standard PLD compilers for Registered, Complex, and Simple modes

Applications

• Replacement for legacy 20-pin PAL devices in industrial control systems
• State machine implementation requiring registered output initialization
• Complex logic functions utilizing feedback paths in complex mode

Procurement Notes

Verify the package type 'S' corresponds to the 20-lead Plastic Gull-wing Small Outline (SOIC) format as defined in the ordering information table. Confirm the 'I' suffix indicates the Industrial temperature range (-40°C to +85°C). Ensure programming hardware supports the specific Flash memory interface required for this EEPLD family.

Selection Notes

Select the ATF16V8B-10SI when a 10 ns speed grade is required for industrial environments. Compare against the commercial variant (ATF16V8B-10SC) if operating temperatures remain within 0°C to 70°C. Consider the BQ or BQL variants if lower standby or active power consumption is necessary for the application.

Part Context

This component belongs to the ATF16V8B series of Electrically Erasable Programmable Logic Devices. The series offers multiple speed grades (7.5 ns, 10 ns, 15 ns, 25 ns) and package options including PLCC, PDIP, SOIC, and TSSOP. The ATF16V8B-10SI specifically denotes the 10 ns speed bin in the industrial temperature range housed in an SOIC package.
