Product details
Overview
ATF22LV10CQZ-30SI 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 standby current via Input Transition Detection (ITD), and supports industrial temperature range (–40°C to +85°C). It replaces the obsolete ATF22LV10CZ and is used in battery-powered control logic, legacy PAL emulation, and power-sensitive state machine implementations.
For engineers reviewing the ATF22LV10CQZ-30SI datasheet, ATF22LV10CQZ-30SI pinout, ATF22LV10CQZ-30SI application, or ATF22LV10CQZ-30SI equivalent, key selection criteria include its zero-power ITD mode, 24-pin SOIC (24S) industrial-grade packaging, Flash-based reprogrammability, 20-year data retention, and compatibility with 5V-tolerant TTL/CMOS systems requiring deterministic power-down behavior.
Technical Context
The ATF22LV10CQZ-30SI implements a variable product-term architecture with 8–16 product terms per output, plus two shared product terms for synchronous/asynchronous reset. Its patented Input Transition Detection circuit automatically powers down to ≤25 µA standby when idle, eliminating external power management logic.
Each of its 10 macrocells is configurable as registered or combinatorial, active-high or active-low output. Pin-keeper circuits maintain input/I/O states during idle periods, preventing static current draw from pull-up resistors - critical for battery-operated systems where leakage must be minimized without sacrificing signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 30 ns max - guarantees timing-critical logic paths meet 33.3 MHz system clock requirements with margin. |
| Supply Voltage Range | 3.0 V to 5.5 V - enables direct interface with both 3.3 V and 5 V logic families without level shifters. |
| Standby Current (ISB) | ≤25 µA at VCC = 5.5 V - achieved via Input Transition Detection, enabling multi-year battery life in always-on monitoring nodes. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including motor controls and factory automation equipment. |
| Logic Density | 22-pin equivalent PAL - supports emulation of legacy 24-pin PAL devices with full pinout compatibility in SOIC/TSSOP packages. |
| Data Retention | 20 years - ensures firmware and configuration persistence across product lifecycle without refresh. |
| Erase/Write Cycles | 10,000 - supports field firmware updates and design iteration without hardware replacement. |
Pinout & Package
ATF22LV10CQZ-30SI is packaged in a 24-lead, 0.300" wide plastic gull-wing small outline (SOIC), designated 24S per Atmel's ordering code. This RoHS-compliant, green (Pb/halide-free) package measures 15.2–15.6 mm × 7.4–7.6 mm × 2.65 mm max height.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1–11, 13, 24 | IN | 12 dedicated logic inputs; all 5V-tolerant and equipped with internal keeper circuits to retain last-driven state during idle. |
| 12 | GND | Ground reference for all internal logic and I/O buffers; decoupling capacitor placement adjacent is required for noise immunity. |
| 14–23 | I/O | 10 bidirectional macrocell I/Os; each configurable as registered/combinatorial and active-high/low; includes output enable control. |
| 24 | VCC | Primary power supply (3.0–5.5 V); requires local 0.1 µF ceramic decoupling to suppress high-frequency switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Input Transition Detection (ITD) | Automatically reduces ICC to ≤25 µA when no input transitions occur - eliminates need for external sleep controllers in portable systems. |
| Flash-based EE Technology | 100% tested reprogrammability with 10,000 erase/write cycles and 20-year data retention - enables secure, field-upgradable logic configurations. |
| 5V-Tolerant Inputs | Accepts 0–5.5 V input signals while powered from 3.3 V - simplifies mixed-voltage board design and avoids level-shifter components. |
| Pin-keeper Circuits | Maintains stable logic states on all IN and I/O pins during idle - prevents floating inputs from inducing shoot-through current in downstream CMOS gates. |
| Security Fuse | One-time programmable fuse blocks unauthorized readback of JEDEC fuse patterns - protects proprietary logic designs from cloning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Lattice GAL22V10D-15LP | 15 ns tPD, 5 V only (4.75–5.25 V), EEPROM-based, no ITD or zero-power mode. | Higher speed but higher static current (~100 µA); unsuitable for battery operation. | Select when absolute minimum propagation delay is required and 5 V supply is guaranteed. |
| Microchip ATF22LV10CQZ-30JI | Identical silicon and functionality; differs only in PDIP (24P3) packaging and commercial vs. industrial temp grading. | Same logic behavior but larger footprint and lower thermal robustness; not rated for –40°C operation. | Choose only if legacy through-hole assembly is mandated and ambient temperature stays within 0°C–70°C. |
Compared with GAL22V10D-15LP, ATF22LV10CQZ-30SI trades 15 ns speed for 75% lower standby current and true 3.3 V compatibility; versus ATF22LV10CQZ-30JI, it provides verified industrial-grade thermal performance and smaller SOIC footprint - making it the sole choice for new designs requiring extended temperature range and space-constrained layouts.

FAQ
What is the maximum operating frequency supported by the ATF22LV10CQZ-30SI?
The ATF22LV10CQZ-30SI supports a maximum external feedback frequency of 33.3 MHz, derived from its 30 ns propagation delay and 15 ns setup time. This is confirmed in the AC Characteristics table (Section 4.3) of the official datasheet, where fMAX is specified as 33.3 MHz for the -30 speed grade under industrial conditions. The device achieves this timing while maintaining full functionality across its 3.0–5.5 V supply range.
Does the ATF22LV10CQZ-30SI require an external programmer, and what file format does it use?
Yes, the ATF22LV10CQZ-30SI requires a standard CMOS PLD programmer supporting JEDEC JED files. Programming is performed via dedicated programming hardware (e.g., BP Microsystems, Xeltek, or Microchip's own tools), and the compiled output is a JEDEC-standard file containing fuse map data, preload vectors, and security fuse settings. The device does not support in-system programming (ISP) or serial configuration interfaces.
How does the Input Transition Detection (ITD) circuit reduce power consumption in the ATF22LV10CQZ-30SI?
The ITD circuit in the ATF22LV10CQZ-30SI monitors all 12 input pins for voltage transitions. When no transitions occur for a defined internal timeout, the device automatically enters zero-power standby mode, reducing ICC to ≤25 µA. This eliminates static current draw without software intervention or external control signals - a key enabler for multi-year battery life in always-on edge sensors and remote telemetry units.
Is the ATF22LV10CQZ-30SI pin-compatible with the older ATF22LV10CZ-25JC?
Yes, the ATF22LV10CQZ-30SI shares identical pinout, function mapping, and macrocell architecture with the ATF22LV10CZ-25JC across all package types (SOIC, TSSOP, PLCC, PDIP). The "CQZ" designation indicates enhanced low-voltage operation and improved standby current over the "CZ" variant, but electrical and mechanical compatibility is preserved - enabling direct replacement in existing designs without layout changes.
What is the purpose of the 64-bit User Signature memory in the ATF22LV10CQZ-30SI?
The ATF22LV10CQZ-30SI includes 64 bits of dedicated, unsecured user-accessible memory that remains readable even after the security fuse is programmed. This area is commonly used to store project identifiers, revision numbers, calibration data, or manufacturing timestamps - providing traceability and version control without compromising intellectual property protection of the main logic configuration.
