Product details
Overview
AT22LV10L-25JI from Atmel is a low-voltage, UV-erasable, reprogrammable PLD based on the 22V10 architecture, featuring 10 macrocells, 22 inputs, and 10 I/O pins. It operates across 3.0V–5.5V supply, delivers 25 ns maximum propagation delay at VCC = 3.0V, and draws only 1 mA typical ICC at 3.3V - optimized for battery-powered logic control in industrial embedded systems.
For engineers reviewing the AT22LV10L-25JI datasheet, AT22LV10L-25JI pinout, AT22LV10L-25JI application, or AT22LV10L-25JI equivalent, this device serves as a drop-in low-power replacement for standard 22V10 PLDs where extended battery life, CMOS-compatible I/O, and industrial-temperature operation (-40°C to +85°C) are required.
Technical Context
The AT22LV10L-25JI implements a fixed 22-input × 10-output PLD architecture with eight to sixteen product terms per output, plus two global product terms for synchronous preset and asynchronous reset shared across all ten registers. All registers power-up cleared and support asynchronous preload via dedicated voltage-level control on I/O pins.
It uses low-power CMOS technology with ±10 µA max input/output leakage, 2000V HBM ESD protection, and 200 mA latchup immunity. Its AC timing is fully specified over 3.0V–5.5V, enabling stable operation in mixed-voltage systems without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 25 ns max at VCC = 3.0V - ensures timing closure in 3.3V logic control paths with ≥32 MHz external feedback clocking |
| Supply Voltage Range | 3.0V to 5.5V - supports direct interface with 3.3V microcontrollers and legacy 5V peripherals |
| ICC (Typical) | 1 mA at VCC = 3.3V - enables multi-year operation in coin-cell–powered instrumentation |
| Input/Output Leakage | ±10 µA max - minimizes standby current in high-impedance bus-hold or sensor interface circuits |
| Operating Temperature | -40°C to +85°C - qualified for industrial automation, motor drives, and outdoor telemetry nodes |
| ESD Protection | 2000V HBM - meets IEC 61000-4-2 Level 2 for board-level robustness in factory environments |
| Logic Architecture | 22V10-compatible - enables reuse of existing ABEL or CUPL design files and programming toolchains |
Pinout & Package
AT22LV10L-25JI is supplied in a 28-lead Plastic J-Leaded Chip Carrier (PLCC) package, JEDEC MS-018AB compliant, with 1.27 mm pitch and body size 11.4 mm × 11.4 mm. Pin 1 is marked by a corner notch and located at top-left when viewed from top with notch up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–11, 13–22, 24 | IN / CLK/IN | 22 dedicated logic inputs; Pin 1 doubles as clock input - supports edge-triggered state machines without external gating |
| 12 | GND | Ground reference for all I/O and core logic - must be connected to low-impedance system ground plane |
| 23 | VCC | Primary power supply pin - requires local 100 nF ceramic decoupling within 5 mm |
| 25–28, 1–10 (PLCC) | I/O | 10 bidirectional I/O pins with full CMOS output levels - each configurable as registered or combinatorial output |
Key Features
| Feature | Design Value |
|---|---|
| Reprogrammable UV-erasable fuse array | Enables iterative firmware-logic co-development and field updates using standard UV erasers (≥20 min @ 12,000 µW/cm²) |
| Asynchronous register preload | Allows deterministic test initialization via 11.5–13V pulse on I/O pins - eliminates boot-state uncertainty in safety-critical sequencers |
| Power-up reset circuitry | Guarantees all registers initialize low at VCC > 2.5V - critical for FSMs requiring known startup state without external POR |
| Security fuse | Prevents unauthorized readback of programmed logic pattern - protects proprietary glue-logic IP in OEM designs |
| CMOS/TTL-compatible I/O | Accepts TTL-level inputs and drives CMOS loads directly - eliminates level shifters in mixed-technology backplanes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT22LV10-25JI | Higher ICC (4–5 mA typical at 3.3V); same 22V10 architecture and 28J package | Less suitable for ultra-low-power battery operation; otherwise pin- and function-compatible | Select AT22LV10-25JI only when higher drive strength or legacy qualification data is required |
| AMD PALCE22V10-25JC | Commercial-temp only (0°C to 70°C); 25 ns speed grade; 24-pin PDIP/SOIC packages only | Not rated for industrial environments; lacks UV window for field reprogramming | Use AMD PALCE22V10-25JC only in cost-sensitive commercial products with no temperature or reprogrammability requirements |
Compared with AT22LV10-25JI and AMD PALCE22V10-25JC, the AT22LV10L-25JI uniquely combines industrial temperature rating, single-digit-mA power consumption, and field-erasable programmability in a surface-mount PLCC - making it the sole choice for ruggedized, long-life, upgradeable logic in embedded systems.

FAQ
What is the maximum operating voltage for AT22LV10L-25JI?
The AT22LV10L-25JI supports a wide supply range of 3.0V to 5.5V DC. This allows direct interfacing with both 3.3V and 5V logic families without level translation. Operation above 5.5V risks permanent damage, as absolute maximum ratings specify VCC ≤ 7.0V only under transient conditions (≤20 ns pulses).
Does AT22LV10L-25JI require external programming hardware?
Yes, the AT22LV10L-25JI requires a UV-erasable PLD programmer compatible with 22V10 architecture, such as the Data I/O PS-29 or BP Microsystems Model 3000. Programming uses standard 12.5V VPP pulses; erasure requires 20+ minutes under 2537 Å UV light through the PLCC window. No in-system programming capability is supported.
Is AT22LV10L-25JI pin-compatible with standard 22V10 devices?
Yes, the AT22LV10L-25JI maintains identical pinout and logic architecture to the original 22V10, including the 28J PLCC package. All 22 inputs, 10 I/Os, VCC, and GND map identically - enabling direct replacement in legacy designs without PCB modification.
What is the power-up reset behavior of AT22LV10L-25JI?
The AT22LV10L-25JI features internal power-up reset circuitry that forces all ten registers low when VCC crosses ~2.5V. This occurs within 600–1000 ns (tPR), ensuring deterministic FSM initialization. The reset is asynchronous and independent of clock or input signals - critical for fail-safe startup in industrial controls.
Can AT22LV10L-25JI operate reliably at 3.0V supply?
Yes, AT22LV10L-25JI is fully characterized down to 3.0V: tPD = 25 ns max, ICC = 1–2 mA typical, and VIH/VIL thresholds scale correctly. Its CMOS outputs swing rail-to-rail, ensuring noise margin >0.7V at 3.0V - validated across -40°C to +85°C for battery-powered applications.
