Product details
Overview
ATF22LV10CQZ-30XC from Microchip Technology (formerly Atmel) is a low-voltage, electrically erasable programmable logic device (PLD) with 12 inputs, 10 I/O macrocells, 30 ns maximum propagation delay, 25 µA maximum standby current, and operation from 3.0 V to 5.5 V. It implements registered or combinatorial logic in battery-powered industrial control and legacy interface replacement systems.
For engineers reviewing the ATF22LV10CQZ-30XC datasheet, ATF22LV10CQZ-30XC pinout, ATF22LV10CQZ-30XC application, or ATF22LV10CQZ-30XC equivalent, key selection criteria include input transition detection for zero-power idle mode, 24-pin TSSOP package compatibility, Flash-based reprogrammability, and support for both commercial (0°C to 70°C) and industrial (−40°C to +85°C) temperature ranges.
Technical Context
The ATF22LV10CQZ-30XC uses Atmel's patented Input Transition Detection (ITD) circuitry to automatically enter zero-power standby mode when idle, reducing ICC to ≤25 µA. Its variable product term architecture allocates 8–16 product terms per output, plus two global product terms for synchronous/asynchronous reset.
Each macrocell supports active-high/low and registered/combinatorial configurations, enabling emulation of most 24-pin PAL devices. Register preload and power-up reset ensure deterministic state machine initialization without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 30 ns max - defines worst-case combinational path timing for logic synthesis and critical path analysis |
| Standby Current (ISB) | 25 µA max at VCC = 5.5 V - enables multi-year battery life in always-on sensor nodes |
| Supply Voltage Range | 3.0 V to 5.5 V - supports direct interfacing with 3.3 V and 5 V logic families without level shifters |
| I/O Pin Count | 10 bidirectional I/Os + 12 dedicated inputs - provides sufficient logic density for glue logic and protocol translation |
| Operating Temperature | −40°C to +85°C - qualified for industrial automation and automotive under-hood auxiliary modules |
| Reprogrammability | 10,000 erase/write cycles - allows field firmware updates and design iteration without hardware change |
| Data Retention | 20 years - ensures long-term reliability in unattended infrastructure equipment |
Pinout & Package
ATF22LV10CQZ-30XC is packaged in a 24-lead, 4.4 mm wide, plastic thin shrink small outline (TSSOP) package (JEDEC MO-153 AD), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK/IN | Clock input or general-purpose input | Shared pin supports edge-triggered register operation or static logic input; requires no external pull-up |
| IN1–IN11 | Dedicated logic inputs | 11 total dedicated inputs (including CLK/IN); all 5 V tolerant and CMOS/TTL compatible |
| I/O1–I/O10 | Bidirectional macrocell I/Os | Configurable as registered/combinatorial, active-high/low outputs; feature internal pin-keeper circuits |
| VCC | Power supply | 3.0–5.5 V supply; decoupling required within 10 mm of pin for stable high-speed operation |
| GND | Ground reference | Single ground pin; layout best practice requires low-inductance connection to solid ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Input Transition Detection (ITD) | Automatically powers down to ≤25 µA standby when inputs are static - eliminates need for external sleep controllers |
| Pin-keeper circuits | Maintains last-driven logic state on all inputs and I/Os during idle - removes requirement for external pull-up/down resistors |
| Security fuse | Prevents unauthorized readback of programmed logic pattern while preserving 64-bit user signature memory |
| Power-up reset | Guarantees all registers initialize to low state at VRST = 2.3–2.7 V - ensures deterministic boot behavior in power-rail-sensitive systems |
| Green packaging | Pb/halide-free, RoHS-compliant TSSOP - meets environmental compliance requirements for EU and global markets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF22LV10CQZ-30JI | Same die and architecture, but in PLCC-28 package with industrial temperature rating | Requires larger PCB footprint and manual soldering; preferred for prototyping or through-hole legacy designs | Select when board-level rework or socket-based validation is required |
| ATF22LV10CQZ-30XC (obsolete CZ-25 variant) | 25 ns speed grade, higher ICC (50 mA typical), same pinout and logic architecture | Not recommended for new designs due to obsolescence and higher power consumption | Avoid unless maintaining legacy production with existing CZ-25 tooling and programming fixtures |
Compared with ATF22LV10CQZ-30JI, the ATF22LV10CQZ-30XC offers superior thermal performance and smaller footprint in TSSOP, while the obsolete CZ-25 variant lacks the Q-design's low-power optimizations and has been discontinued by Microchip.

FAQ
What is the maximum clock frequency supported by the ATF22LV10CQZ-30XC?
The ATF22LV10CQZ-30XC supports a maximum external feedback clock frequency of 33.3 MHz, determined by the sum of input setup time (tS = 18 ns max) and clock-to-output delay (tCO = 20 ns max). This limit applies to registered logic paths; combinatorial paths are constrained by tPD = 30 ns. The device achieves this performance across its full 3.0–5.5 V supply range and −40°C to +85°C operating temperature.
Does the ATF22LV10CQZ-30XC require external pull-up resistors on its I/O pins?
No, the ATF22LV10CQZ-30XC does not require external pull-up resistors because it integrates pin-keeper circuits on all inputs and I/O pins. These weak active circuits maintain the last-driven logic state when pins are undriven, eliminating static power consumption and simplifying PCB layout. External drivers can override the keeper state without conflict, supporting clean TTL/CMOS interfacing.
How does the Input Transition Detection (ITD) circuitry reduce power in the ATF22LV10CQZ-30XC?
The ITD circuitry in the ATF22LV10CQZ-30XC monitors all 12 input pins for transitions. When no activity is detected for a defined period, the device automatically enters zero-power standby mode, reducing supply current to ≤25 µA. This occurs without software intervention or external control signals, making it ideal for intermittent-sensing applications like wireless sensor nodes where the IC spends >99% of time idle.
Can the ATF22LV10CQZ-30XC be used as a direct replacement for the ATF22V10CZ?
Yes, the ATF22LV10CQZ-30XC is explicitly positioned as the low-voltage, zero-power equivalent of the ATF22V10CZ, sharing identical pinout, macrocell architecture, and JEDEC file compatibility. However, it operates from 3.0–5.5 V (vs. 4.75–5.25 V for ATF22V10CZ) and delivers significantly lower standby current (25 µA vs. ~10 mA), requiring only verification of supply rail compatibility in the target system.
What programming tools are compatible with the ATF22LV10CQZ-30XC?
The ATF22LV10CQZ-30XC is programmed using standard CMOS PLD programmers that support Atmel's Flash-based SPLD format, including BP Microsystems' Universal Programmers, Xeltek SuperPro series, and third-party tools certified in Atmel's PLD Programming Hardware and Software Support documentation. JEDEC files generated by Atmel WinCUPL or free open-source ABEL compilers are fully compatible, and security fuse programming follows standard ISP protocols.
