Product details
Overview
ATF22LV10CZ-25JC from Atmel is a low-voltage, electrically erasable programmable logic device (PLD) with 12 inputs, 10 I/O macrocells, 25ns propagation delay, 25µA maximum standby current, and operation across 3.0V–5.5V supply. It implements zero-power mode via Input Transition Detection (ITD), supports both combinatorial and registered output configurations, and is used in legacy industrial control logic replacement and battery-powered embedded state machines.
For engineers reviewing the ATF22LV10CZ-25JC datasheet, ATF22LV10CZ-25JC pinout, ATF22LV10CZ-25JC application, or ATF22LV10CZ-25JC equivalent, key selection criteria include its 28-pin PLCC package, industrial temperature range (−40°C to +85°C), Flash-based reprogrammability, 20-year data retention, and compatibility with legacy PAL-22V10 designs requiring low static power and 5V-tolerant inputs.
Technical Context
The ATF22LV10CZ-25JC uses a variable product-term architecture-each of its 10 macrocells allocates 8–16 product terms for complex logic synthesis, plus two shared product terms for synchronous/asynchronous reset. Its patented Input Transition Detection (ITD) circuitry enables automatic entry into zero-power standby when input activity ceases, reducing ICC to ≤25µA at VCC = 5.5V.
It features internal pin-keeper circuits on all inputs and I/Os to maintain last-driven logic states without external pull-ups, supports JEDEC-standard programming with preload capability, and includes a security fuse to prevent unauthorized pattern copying while preserving user-accessible 64-bit signature memory.
Key Specifications

| GND | Ground reference | Multiple GND pins (pins 8, 15, 22) provide low-impedance return paths and enhance signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Input Transition Detection (ITD) | Automatically powers down to ≤25µA standby when inputs are idle-eliminates need for external sleep controllers |

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-30JC | 30ns tPD, lower active current (18mA typ vs. 85mA), green RoHS-compliant PLCC package | Targeted for new designs requiring reduced power consumption and environmental compliance; not pin-compatible due to different speed grade and internal architecture optimizations | Select when upgrading legacy systems where 5ns timing margin is acceptable and RoHS compliance is mandatory |
| AMD AM22V10DCPC | 25ns tPD, bipolar process, 50mA typical ICC, no zero-power mode or ITD circuitry | Used in high-speed, non-battery applications where static power is not constrained; lacks Flash reprogrammability and security fuse | Select only for direct replacement in existing bipolar PAL sockets where zero-power operation is unnecessary |
Compared with ATF22LV10CZ-25JC, the ATF22LV10CQZ-30JC offers lower active power and RoHS compliance but sacrifices 5ns speed; the AM22V10DCPC matches speed and footprint but lacks zero-power capability, reprogrammability, and modern reliability features-making it unsuitable for battery or long-lifecycle applications.

FAQ
What is the maximum standby current specification for ATF22LV10CZ-25JC?
The maximum standby current (ISB) for ATF22LV10CZ-25JC is 25 µA at VCC = 5.5V and TA = 85°C, measured with all inputs held static and outputs open. This ultra-low value is achieved through Atmel's patented Input Transition Detection (ITD) circuitry, which powers down the device automatically when no input transitions occur. The ATF22LV10CZ-25JC maintains this specification across its full industrial temperature range.
Is ATF22LV10CZ-25JC pin-compatible with standard PAL-22V10 devices?
Yes, ATF22LV10CZ-25JC uses the same 28-pin PLCC (28J) package and pinout as industry-standard PAL-22V10 devices, enabling direct socket replacement in legacy designs. Its CLK/IN, IN, and I/O pin assignments match JEDEC-standard 22V10 layouts. However, internal architecture differences-including Flash-based configuration and ITD circuitry-require updated JEDEC programming files, not just physical pin alignment. The ATF22LV10CZ-25JC retains full functional equivalence for combinatorial and registered logic implementations.
Does ATF22LV10CZ-25JC support in-system programming?
No, ATF22LV10CZ-25JC does not support in-system programming (ISP). It requires standard PLD programmers that apply 12V VPP programming voltage to dedicated pins, per Atmel's CMOS PLD Programming Hardware specification. Programming must be performed off-board using compatible devices such as the BP Microsystems SuperPro series or Xeltek universal programmers. The ATF22LV10CZ-25JC lacks the serial interface or internal charge pump needed for ISP, distinguishing it from later-generation CPLDs.
What is the purpose of the security fuse in ATF22LV10CZ-25JC?
The security fuse in ATF22LV10CZ-25JC prevents unauthorized readback of the programmed logic pattern by disabling fuse-map verification and preload operations once blown. It does not affect normal device functionality or the accessibility of the 64-bit User Signature memory, which remains readable regardless of fuse state. Programming the security fuse is irreversible and must be performed after final validation; doing so early risks locking out debug and test capabilities during development. The ATF22LV10CZ-25JC implements this feature using a one-time-programmable metal link within the silicon.
Can ATF22LV10CZ-25JC operate reliably at 3.0V supply voltage?
Yes, ATF22LV10CZ-25JC is fully specified to operate at 3.0V minimum VCC across its entire commercial (0°C to 70°C) and industrial (−40°C to +85°C) temperature ranges. At 3.0V, its tPD increases to 35ns (vs. 25ns at 5.5V), and ICC drops proportionally-enabling use in 3.3V systems with marginal voltage headroom. All DC parameters-including VIH, VOL, and IIH-are guaranteed at 3.0V, and the Input Transition Detection (ITD) circuit remains functional, preserving zero-power behavior. The ATF22LV10CZ-25JC's 3.0V capability makes it suitable for mixed-voltage designs interfacing with modern low-power MCUs.
