Microchip Technology ATF22V10BQL-20JC

Overview

ATF22V10BQL-20JC from Atmel is a high-performance, electrically erasable CMOS programmable logic device (PLD) with 22 inputs, 10 macrocells, and 10 I/O pins. It features 20 ns maximum propagation delay (tPD), 12 ns clock-to-output (tCO), and operates across the full military temperature range (–55°C to +125°C) at 5V ±10%. It is used in legacy industrial control logic, FPGA companion glue logic, and reprogrammable state machine implementations.

For engineers reviewing the ATF22V10BQL-20JC datasheet, ATF22V10BQL-20JC pinout, ATF22V10BQL-20JC application, or ATF22V10BQL-20JC equivalent, key selection criteria include its Flash-based reprogrammability, internal pull-up resistors on all inputs/I/Os, PCI compliance, 20-year data retention, and support for asynchronous reset and synchronous preset functions.

Technical Context

The ATF22V10BQL-20JC implements a fixed architecture PLD with a 22-input AND-OR-invert logic array feeding 10 configurable macrocells. Each macrocell supports combinational or registered output modes, asynchronous reset, and synchronous preset - enabling implementation of finite-state machines and address decoders without external latches.

It uses Atmel's proprietary Flash memory technology for nonvolatile configuration storage, allowing in-system reprogramming without UV erasure. The device integrates input and I/O pull-up resistors, eliminates need for external pull-ups, and meets MIL-STD-883 Class B requirements for military-grade reliability including 2,000V HBM ESD protection and 200mA latchup immunity.

FAQ

What is the maximum operating temperature range for the ATF22V10BQL-20JC?

The ATF22V10BQL-20JC is fully qualified for operation from –55°C to +125°C case temperature, meeting MIL-STD-883 Class B requirements. This specification is verified per the manufacturer's official datasheet revision 0250M–PLD–7/10, and applies to the LCC package variant with JC suffix. The device maintains full AC and DC parameter compliance across this entire range at 5V ±10% supply.

Does the ATF22V10BQL-20JC require external pull-up resistors on its inputs and I/O pins?

No, the ATF22V10BQL-20JC includes internal weak pull-up resistors on all input and I/O pins, eliminating the need for external components. These pull-ups float un-driven pins to VCC and ensure deterministic logic states during power-up or bus idle conditions. They are designed to be easily overridden by TTL-compatible drivers, as confirmed in Section 14 of the official datasheet.

How many times can the ATF22V10BQL-20JC be reprogrammed?

The ATF22V10BQL-20JC supports up to 100 erase/write cycles, as specified in its datasheet under "High-reliability CMOS Process". This endurance rating is guaranteed across the full military temperature range and accounts for worst-case voltage and timing margins. Field programming is performed using standard CMOS PLD programmers compatible with JEDEC file formats.

Is the ATF22V10BQL-20JC PCI compliant, and what does that mean for system design?

Yes, the ATF22V10BQL-20JC is explicitly stated as PCI compliant in its official datasheet Features section. This means its AC timing parameters-including tPD, tCO, and tS-meet the Peripheral Component Interconnect specification's electrical and timing requirements for add-in card logic, enabling direct use in PCI bus interface circuits without additional timing compensation or buffering.

What package type and pin count does the ATF22V10BQL-20JC use?

The ATF22V10BQL-20JC uses a 28-lead ceramic leadless chip carrier (LCC/PLCC) package, designated as 28L in Atmel's ordering documentation. It has a 0.4-inch body width and J-lead terminations, with pin 1 located at the top-left corner when viewed from the top with the notch oriented upward. This matches the standard PLD pinout shown in Figure 0-2 of the datasheet.
