Product details
Overview
ATF22LV10CQZ-30PI from Microchip Technology (formerly Atmel) is a low-voltage, electrically erasable programmable logic device (PLD) with 12 inputs, 10 I/O macrocells, and 30 ns maximum propagation delay. It operates from 3.0V to 5.5V, delivers 25 µA max standby current via Input Transition Detection (ITD), and supports industrial temperature range (–40°C to +85°C) in 24-pin PDIP package. It replaces ATF22LV10CZ for battery-powered and space-constrained embedded control applications.
For engineers reviewing the ATF22LV10CQZ-30PI datasheet, ATF22LV10CQZ-30PI pinout, ATF22LV10CQZ-30PI application, or ATF22LV10CQZ-30PI equivalent, key selection criteria include zero-power idle operation, 5V-tolerant CMOS/TTL-compatible I/Os, register preload capability, asynchronous/synchronous reset architecture, and green RoHS-compliant packaging options.
Technical Context
The ATF22LV10CQZ-30PI implements a variable product-term architecture with 8–16 product terms per output, plus two shared product terms for synchronous and asynchronous reset. Its patented Input Transition Detection (ITD) circuitry enables automatic entry into zero-power mode when input activity ceases, reducing standby ICC to ≤25 µA without external control.
Each of its 10 macrocells supports configurable output polarity and registered/combinatorial modes. Pin-keeper circuits maintain input and I/O states during idle periods, eliminating need for external pull-ups and minimizing static power. The device features a security fuse and 64-bit user-accessible signature memory independent of fuse status.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Lattice GAL22V10D-15LP | 15 ns tPD, 5V-only supply (4.75–5.25V), EEPROM-based, no ITD zero-power mode | Higher speed but lacks low-voltage operation and ultra-low standby current | Choose when system requires faster timing and runs exclusively at 5V with adequate thermal margin |
| Microchip ATF22LV10CQZ-30JI | Identical silicon and architecture; differs only in industrial-grade screening and extended temperature qualification | Same functionality but guaranteed for –40°C to +85°C with full parametric testing | Prefer for new designs targeting industrial or automotive ambient conditions where temperature validation is mandatory |

FAQ
What is the maximum clock frequency supported by ATF22LV10CQZ-30PI?
The ATF22LV10CQZ-30PI supports a maximum external clock frequency of 33.3 MHz when using internal feedback and 40.0 MHz with no feedback path, based on its 30 ns propagation delay and specified setup/hold timing margins. These values are guaranteed across the full 3.0V–5.5V supply and –40°C to +85°C temperature range. Actual system-level frequency depends on board layout, loading, and logic depth implemented in the fuse map.
Does ATF22LV10CQZ-30PI require an external programmer, and what file format does it use?
Yes, ATF22LV10CQZ-30PI requires a standard CMOS PLD programmer supporting JEDEC JESD-30 or JED files. It accepts JEDEC-format programming files generated by Atmel WinCUPL or third-party CPLD tools. Preload vectors and security fuse settings are embedded in the JEDEC file, and most compliant programmers execute the full sequence-including optional register preload-automatically upon download.
Can ATF22LV10CQZ-30PI operate reliably at 3.0V supply voltage?
Yes, ATF22LV10CQZ-30PI is fully specified and tested down to 3.0V supply voltage across commercial and industrial temperature ranges. Its 30 ns propagation delay, 25 µA max standby current, and 16 mA output drive capability are all guaranteed at VCC = 3.0V, making it suitable for direct interfacing with 3.3V microcontrollers and battery-powered systems where voltage regulation headroom is limited.
How does the Input Transition Detection (ITD) circuitry reduce power in ATF22LV10CQZ-30PI?
The ITD circuitry in ATF22LV10CQZ-30PI continuously monitors all 12 input pins for transitions. When no edge is detected for a defined internal timeout, the device automatically enters zero-power standby mode, disabling internal logic clocks and reducing ICC to ≤25 µA. This occurs without software intervention or external control signals-only input activity restores full operation, making it ideal for intermittent-event systems like alarm inputs or pushbutton interfaces.
Is ATF22LV10CQZ-30PI pin-compatible with older PAL22V10 devices?
Yes, ATF22LV10CQZ-30PI uses the standard 24-pin DIP (24P3) footprint and pinout matching industry-standard PAL22V10 devices, including identical CLK, I/O, and GND/VCC locations. Its 5V-tolerant inputs and CMOS/TTL-compatible outputs ensure electrical compatibility, allowing direct replacement in legacy designs without PCB modification-provided timing constraints and voltage levels align with the -30PI's 3.0–5.5V operating range.
