Microchip Technology ATF22V10B-15JC

Overview

ATF22V10B-15JC from Atmel is a high-performance, electrically erasable CMOS programmable logic device (PLD) with 22 inputs, 10 macrocells, and 10 I/Os. It delivers 15 ns propagation delay (tPD), supports 5 V ±10% supply across military temperature range (–55°C to +125°C), and features Flash-based reprogrammability with 100 erase/write cycles and 20-year data retention.

For engineers reviewing the ATF22V10B-15JC datasheet, ATF22V10B-15JC pinout, ATF22V10B-15JC application, or ATF22V10B-15JC equivalent, this device serves as a drop-in replacement for industry-standard 22V10 PLDs in legacy logic consolidation, glue logic, and state machine control where deterministic timing, nonvolatile configuration, and military-grade reliability are required.

Technical Context

The ATF22V10B-15JC implements a fixed architecture with 22 input pins feeding a programmable AND-OR logic array and 10 macrocells-each configurable as registered or combinatorial output. Its internal clock path supports synchronous operation with tCO ≤ 8 ns and tCF = 2.5 ns, enabling reliable state machine sequencing at up to 55.5 MHz (external feedback mode).

It integrates on-chip input/I/O pull-up resistors, 2,000 V HBM ESD protection, and latchup immunity of 200 mA. Power-up reset ensures deterministic register initialization, and the security fuse prevents unauthorized JEDEC file copying while preserving 64-bit user signature access.

The ATF22V10B series was designed as a Flash-based, military-qualified replacement for industry-standard 22V10 PLDs-targeting legacy system upgrades, defense electronics modernization, and long-lifecycle industrial control applications.

FAQ

What is the maximum operating frequency supported by ATF22V10B-15JC?

The ATF22V10B-15JC supports an external feedback maximum frequency of 55.5 MHz, calculated as 1/(tS + tCO) = 1/(10 ns + 8 ns). This applies to synchronous designs using registered outputs with feedback paths; combinatorial-only paths achieve up to 83.3 MHz with no feedback.

Does ATF22V10B-15JC require external pull-up resistors on input pins?

No. The ATF22V10B-15JC includes internal weak pull-up resistors on all IN and I/O pins, ensuring defined logic states when inputs float. These pull-ups are compatible with TTL drivers and eliminate the need for external components unless stronger drive strength is required.

Is ATF22V10B-15JC pin-compatible with standard 22V10 PLDs?

Yes. The ATF22V10B-15JC uses the industry-standard 24-pin DIP pinout (24D3 package) and matches the pin assignments of original bipolar and CMOS 22V10 devices-including identical CLK/IN, IN, I/O, GND, and VCC locations-enabling direct replacement without PCB modification.

How does the power-up reset function in ATF22V10B-15JC affect system initialization?

The ATF22V10B-15JC asserts a hardware reset to all registers when VCC crosses VRST (3.8–4.5 V), forcing them to low state. For reliable initialization, VCC must rise monotonically, and all input setup times must be met before the first clock edge-ensuring deterministic FSM start-up behavior.

Can ATF22V10B-15JC be programmed using standard PLD programmers?

Yes. The ATF22V10B-15JC is fully compatible with industry-standard CMOS PLD programmers supporting JEDEC file download. Programming requires 5 V VCC and standard 14.0 V VPP for write/erase cycles; no special voltage sequencing or adapters are needed for ATF22V10B-15JC.
