Product details

Overview

AT22LV10L-25PI 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 max propagation delay at V_CC = 3.0V, and draws only 1 mA typical ICC at 3.3V - optimized for battery-powered logic control in embedded state machines and glue logic.

For engineers reviewing the AT22LV10L-25PI datasheet, AT22LV10L-25PI pinout, AT22LV10L-25PI application, or AT22LV10L-25PI equivalent, key selection criteria include its low-power CMOS operation, full CMOS output levels, ±10 µA input/output leakage, 2000V ESD rating, and compatibility with standard 22V10 programming tools and JEDEC-standard 24-pin PDIP packaging.

Technical Context

The AT22LV10L-25PI implements a fixed 22-input × 10-output programmable array logic (PAL)-style architecture with eight to sixteen product terms per macrocell, plus two global product terms for synchronous preset and asynchronous reset shared across all registers. All ten registers feature power-up reset and asynchronous preload capability via dedicated voltage-level signaling on I/O pins.

It supports three output configurations (combinatorial, registered, and registered with polarity control), uses UV-erasable fuse-based programming, and maintains full TTL/CMOS input/output compatibility while operating down to 3.0V - enabling direct replacement of legacy 22V10 devices in low-voltage systems without level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	3.0V to 5.5V - enables single-supply operation in mixed-voltage systems and eliminates need for external regulators in 3.3V or 5V designs.
t_PD Max	25 ns at V_CC = 3.0V - guarantees timing closure in 33 MHz synchronous logic paths with margin.
I_CC Typ	1 mA at V_CC = 3.3V - reduces system standby power by >95% versus standard 22V10, critical for portable equipment.
Input Leakage	±10 µA max - ensures reliable high-impedance interface with microcontroller GPIOs and analog sensors.
ESD Rating	2000V HBM - meets industrial handling requirements without additional protection circuitry.
Package	24-lead PDIP (24P3) - supports through-hole prototyping, legacy board reuse, and socket-based reprogramming.

Pinout & Package

AT22LV10L-25PI is supplied in a 24-lead, 0.300" wide plastic dual-inline package (PDIP), designated 24P3 per JEDEC MS-011 AB. Pin 1 is marked with a notch or dot; device is top-view oriented with pin 1 at bottom-left corner.

Pin/Terminal	Circuit Role	Design Meaning
1–10, 12–19, 21–24	IN / I/O	22 logic inputs + 10 bidirectional I/O pins - configurable as inputs, combinatorial outputs, or registered outputs with polarity control.
11	GND	Ground reference for all internal logic and I/O buffers - must be connected directly to system ground plane.
20	V_CC	Primary power supply pin - accepts 3.0V–5.5V; decoupling capacitor (0.1 µF) required within 1 cm.
22	CLK/IN	Dual-function pin - serves as global clock input for registered outputs or as general-purpose logic input when not used as clock.

Key Features

Feature	Design Value
UV-erasable fuse programming	Enables full reprogramming up to 100% tested cycles - supports iterative design validation and field firmware updates using standard EPROM programmers.
Power-up register reset	Guarantees known initial state (low) on all 10 registers at V_CC > 2.5V - eliminates metastability in state machines without external reset circuitry.
Asynchronous register preload	Allows forcing any logic state into registers via VIH/VIL on I/O pins during 11.5–13V pulse - simplifies boundary-scan testing and functional verification.
Security fuse	Prevents unauthorized readback of programmed fuse map - protects proprietary logic design from reverse engineering or cloning.

Equivalent & Alternatives

The following parts are listed as comparable options for similar programmable logic device applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AT22LV10-25PI	Higher ICC (4–5 mA typ at 3.3V); same pinout, architecture, and speed grade.	Not suitable for ultra-low-power battery systems; acceptable where legacy 22V10 timing margins apply.	Select when existing AT22LV10-25PI designs require minimal change but lower power is not mandatory.
AMD PALCE22V10-25JC	Commercial temp only (0°C–70°C); 5V-only operation; 25 ns t_PD at 5V only.	Limited to non-industrial environments; requires level-shifting if interfacing with 3.3V microcontrollers.	Choose only for cost-sensitive commercial products with stable 5V rails and no extended temperature requirement.

Compared with AT22LV10-25PI and AMD PALCE22V10-25JC, the AT22LV10L-25PI uniquely combines industrial temperature support, sub-2 mA active current, and true 3.0V–5.5V operation - making it the sole option for battery-powered, wide-temperature, drop-in 22V10 replacements requiring verified low-power performance.

FAQ

What is the maximum operating voltage for AT22LV10L-25PI?

The AT22LV10L-25PI supports a V_CC range of 3.0V to 5.5V. Its absolute maximum rating is 7.0V on any pin relative to ground, but sustained operation above 5.5V violates specification and risks permanent damage. The device is fully characterized and guaranteed across the entire 3.0V–5.5V range, including timing and DC parameters.

Does AT22LV10L-25PI support in-system programming?

No, the AT22LV10L-25PI is a UV-erasable PLD and does not support in-system programming. Programming requires exposure to 253.7 nm ultraviolet light for ≥20 minutes to erase the fuse array, followed by parallel programming in a dedicated EPROM-style programmer. It lacks JTAG or serial interfaces for field reconfiguration.

Can AT22LV10L-25PI replace a standard 22V10-25PC on the same PCB?

Yes, AT22LV10L-25PI uses the identical 24P3 PDIP package and pinout as the 22V10-25PC, and is functionally compatible with standard 22V10 fuse maps. However, verify that the host system's V_CC is ≥3.0V and that timing margins accommodate the same 25 ns t_PD - no PCB changes are needed for mechanical or electrical integration.

What is the purpose of the CLK/IN pin on AT22LV10L-25PI?

The CLK/IN pin (Pin 22) serves a dual role: when configured as a clock input, it synchronizes all ten registers; when unused as a clock, it functions as a standard logic input. Its behavior is determined by fuse configuration - no external mode-select signal is required. This flexibility allows reuse of the same physical pin for timing-critical or combinatorial logic paths.

Is AT22LV10L-25PI qualified for industrial temperature operation?

Yes, the "I" suffix in AT22LV10L-25PI denotes industrial temperature grade (-40°C to +85°C), confirmed in the Ordering Information table and DC/AC Operating Conditions section. It is fully specified and tested across this range for all parameters including t_PD, I_CC, and V_IL/V_IH, making it suitable for harsh-environment control applications.
