Product details
Overview
ATF22LV10CQZ-30JI 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 industrial temperature range (–40°C to +85°C). It implements complex combinational or registered logic in battery-powered embedded control and legacy interface replacement applications.
For engineers reviewing the ATF22LV10CQZ-30JI datasheet, ATF22LV10CQZ-30JI pinout, ATF22LV10CQZ-30JI application, or ATF22LV10CQZ-30JI equivalent, key selection criteria include its zero-power Input Transition Detection (ITD) circuitry, 3.0V–5.5V supply flexibility, 28-pin PLCC industrial-grade package, Flash-based reprogrammability, and compatibility with legacy PAL22V10 designs.
Technical Context
The ATF22LV10CQZ-30JI uses a variable product-term architecture with 8–16 product terms per output plus two global asynchronous/synchronous reset terms. Its patented Input Transition Detection (ITD) circuitry enables automatic entry into zero-power standby mode when input activity ceases, reducing ICC to ≤25 µA at VCC = 5.5 V.
Each of its 10 macrocells supports configurable output polarity and registered/combinatorial modes. Internal pin-keeper circuits maintain last-driven logic states on all inputs and I/Os during idle periods, eliminating external pull-up resistors and associated static power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 30 ns max - ensures timing compliance in 33 MHz synchronous systems with margin |
| Standby Current (ISB) | 25 µA max at VCC = 5.5 V - enables multi-year operation in coin-cell–powered devices |
| Supply Voltage Range | 3.0 V to 5.5 V - supports direct interfacing with both 3.3 V and 5 V logic families without level shifters |
| Operating Temperature | –40°C to +85°C - qualified for industrial control, automotive under-hood (non-safety), and outdoor equipment |
| I/O Count | 12 inputs + 10 I/Os - provides full pin compatibility with industry-standard 24-pin PAL architectures |
| Logic Density | 22V10-equivalent - implements up to 16 product terms per macrocell for medium-complexity glue logic |
| Technology | Flash-based EEPROM - allows unlimited reprogramming in-system without UV erasure or socket removal |

Key Features
| Feature | Design Value |
|---|---|
| Input Transition Detection (ITD) | Automatically powers down to ≤25 µA standby when no input transitions occur - eliminates manual sleep control logic |
| Pin-keeper Circuits | Maintains last-driven state on all IN/I/O pins during idle - removes need for external pull-ups and saves PCB space |
| Security Fuse | One-time programmable fuse blocks unauthorized readback of JEDEC fuse pattern - protects IP in production firmware |
| User Signature Memory | 64-bit accessible nonvolatile memory - stores revision ID, calibration data, or traceability codes independent of security fuse state |
| Power-up Reset (TPR) | Guaranteed register initialization at VRST = 2.3–2.7 V - ensures deterministic state machine startup without external POR circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF22LV10CZ-25JI | 25 ns speed grade, higher ICC (90 mA typical), obsolete per Atmel doc 0779M; same PLCC-28 package | Limited to lower-frequency designs where 25 ns timing margin is required; not recommended for new designs | Select only for legacy repair or second-source validation where 25 ns tPD is mandatory and CQZ-30JI timing margin is insufficient |
| Lattice GAL22V10D-15LPI | 15 ns tPD, 5 V only (4.75–5.25 V), EEPROM-based, 28-pin PLCC; no ITD or zero-power standby | Requires external power management for low-power operation; lacks input keepers and voltage flexibility | Choose when maximum speed is critical and system operates exclusively at 5 V with active power control infrastructure |
Compared with ATF22LV10CZ-25JI and GAL22V10D-15LPI, the ATF22LV10CQZ-30JI uniquely delivers industrial-grade 3.0–5.5 V operation, sub-30 µA zero-power standby via ITD, and integrated pin-keepers - making it the only option enabling true maintenance-free, long-life battery operation without external support circuitry.

FAQ
What is the maximum operating frequency supported by the ATF22LV10CQZ-30JI?
The ATF22LV10CQZ-30JI supports a maximum external feedback clock frequency of 33.3 MHz, derived from its 30 ns propagation delay and 15 ns setup time. This is confirmed in Section 4.3 AC Characteristics of the official datasheet (0779M–PLD–7/10), where fMAX is specified as 33.3 MHz for the -30 speed grade under industrial conditions. The ATF22LV10CQZ-30JI achieves this while maintaining full functionality across its 3.0–5.5 V supply range.
Does the ATF22LV10CQZ-30JI require external pull-up resistors on its I/O pins?
No, the ATF22LV10CQZ-30JI includes internal pin-keeper circuits on all inputs and I/Os that actively hold the last-driven logic state during idle periods. As documented in Section 8 of the datasheet, these weak but effective keepers eliminate the need for external pull-up resistors, reducing BOM count, PCB area, and static power consumption - a key enabler for battery-operated applications using the ATF22LV10CQZ-30JI.
Is the ATF22LV10CQZ-30JI pin-compatible with the original PAL22V10?
Yes, the ATF22LV10CQZ-30JI is functionally and physically pin-compatible with industry-standard 24-pin PAL22V10 devices when used in 24-pin SOIC or PDIP packages. However, the ATF22LV10CQZ-30JI in PLCC-28 (J-lead) requires adapter routing due to its 28-pin footprint. Its macrocell architecture, pin naming convention (CLK/IN, IN, I/O), and JEDEC fuse map structure preserve full design reuse for the ATF22LV10CQZ-30JI in legacy PAL22V10 sockets.
How does the Input Transition Detection (ITD) circuitry reduce power in the ATF22LV10CQZ-30JI?
The ITD circuitry in the ATF22LV10CQZ-30JI monitors all input pins for logic transitions and automatically places the device into zero-power standby mode when no activity is detected for >100 ns. As verified in Section 1 and Figure 1-1 of the datasheet, this reduces ICC to ≤25 µA - a 99.97% reduction versus active-mode current - without software intervention. This feature is intrinsic to the ATF22LV10CQZ-30JI's Flash PLD architecture and requires no external components.
Can the ATF22LV10CQZ-30JI be programmed using standard PAL programmers?
Yes, the ATF22LV10CQZ-30JI is fully compatible with industry-standard PLD programmers supporting JEDEC file format, including Data I/O PS-200, BP Microsystems Series, and Xeltek SuperPro programmers. Programming/erasing procedures follow standard CMOS PLD protocols as outlined in Section 7 of the datasheet, with no special voltage sequences required. The ATF22LV10CQZ-30JI accepts standard 5 V VPP programming voltage and verifies correctly under standard JEDEC pattern checks.
