Product details
Overview
ATF750LVC-15XU from Atmel is a high-performance, electrically-erasable complex programmable logic device (CPLD) in a 24-pin TSSOP package, featuring 20 D/T-type flip-flops, 42 array inputs, and 171 product terms. It supports 3.0V–5.5V operation, delivers ≤15 ns pin-to-pin delay at 3V, and enables reprogrammable logic for embedded control and glue logic replacement in industrial systems.
For engineers reviewing the ATF750LVC-15XU datasheet, ATF750LVC-15XU pinout, ATF750LVC-15XU application, or ATF750LVC-15XU equivalent, this device serves as a superset of the 22V10 architecture with enhanced register flexibility, programmable pin-keeper circuits, and dual clocking modes-critical for state-machine implementation, bus interface logic, and legacy PLD upgrades requiring industrial temperature support.
Technical Context
The ATF750LVC-15XU implements a 20-register, 20-output logic array with fully independent feedback paths and per-flip-flop clock source selection-either via dedicated product-term clocks or direct input pin (CLK/IN). Its architecture supports both synchronous preset and individual asynchronous reset per register, enabling robust initialization and fault recovery in real-time control systems.
Each of its 10 I/O pins provides bi-directional capability with dedicated output-enable product terms, while all 20 flip-flops feed back into the logic array. Pin-keeper circuits are software-configurable to eliminate floating inputs without external pull-ups-reducing board space and static power consumption in unpopulated or tri-stated configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 20 flip-flops + 20 outputs + 171 product terms - enables full-state machines and multi-function glue logic in single 24-pin device. |
| Propagation Delay | ≤15 ns at 3V / ≤10 ns at 5V - ensures timing-critical signal routing meets sub-100 MHz system clock domains. |
| Operating Voltage | 3.0V–5.5V - supports mixed-voltage board designs and legacy 5V TTL compatibility with modern 3.3V logic. |
| Temperature Range | −40°C to +85°C - qualified for industrial environments including motor drives, PLC I/O modules, and factory automation controllers. |
| Endurance | 1000 erase/write cycles with 20-year data retention - suitable for field-upgradable firmware logic in deployed equipment. |
| ESD Protection | 2000V HBM - enhances reliability during handling and in noisy industrial signal environments. |

Pinout & Package
ATF750LVC-15XU is housed in a 24-lead Thin Shrink Small Outline Package (TSSOP), designated 24X per Atmel's ordering information. This RoHS-compliant, Pb/halide-free package measures 7.8 mm × 4.4 mm × 1.2 mm max and features gull-wing leads with 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK/IN (Pin 1) | Dedicated clock input or general logic input | Enables direct pin-controlled clocking for selected flip-flops; eliminates need for internal clock routing resources. |
| IN (Pins 2–11, 13–14, 22–24) | Logic input or feedback path | 12 dedicated input pins plus 10 I/Os configurable as inputs - total 22 logic inputs support wide fan-in combinational logic. |
| I/O (Pins 12, 15–21) | Bi-directional I/O buffer | 10 pins support input, output, or bidirectional mode; each has independent output-enable product term and internal feedback path. |
| VCC (Pins 16, 23) | Power supply | Dual VCC pins improve power integrity and reduce IR drop across logic array under switching load. |
| GND (Pins 17, 24) | Ground reference | Dual ground pins minimize ground bounce and stabilize timing margins during high-speed transitions. |
Key Features
| Feature | Design Value |
|---|---|
| D- or T-type flip-flop per register | Each of 20 registers individually configurable - enables efficient JK/SR synthesis and reduces product-term usage in sequential logic. |
| Programmable pin-keeper circuits | Eliminates external pull-up resistors on unused I/Os - cuts BOM cost and static current draw in low-power standby states. |
| Two clocking modes | Per-flip-flop selection between product-term clock (flexible edge control) and CLK/IN pin (low-jitter, deterministic timing). |
| Asynchronous reset per flip-flop | Independent reset control allows selective clearing of pipeline stages or state registers without affecting others. |
| Synchronous preset for all registers | Single global preset line simplifies boot-time initialization and test-mode entry across entire logic block. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750LVC-15PU | Same logic architecture and AC specs, but in 24-lead PDIP (24P3) package - through-hole mount, wider 0.300" body, higher thermal resistance. | Preferred for prototyping, manual rework, or legacy through-hole production lines; not suitable for high-density SMT assemblies. | Select ATF750LVC-15PU only when board design mandates through-hole mounting or requires easier hand-soldering access. |
| ATF750LVC-15JU | Identical logic and timing, but in 28-lead PLCC (28J) package - larger footprint, J-leads, higher I/O count (22 logic pins vs. 22 on XU), same industrial temp rating. | Used where additional I/Os or socket-based field replacement is needed; PLCC supports zero-insertion-force sockets for serviceability. | Choose ATF750LVC-15JU when socketability, higher pin count, or legacy PLCC layout compatibility outweighs size constraints. |
Compared with ATF750LVC-15PU and ATF750LVC-15JU, the ATF750LVC-15XU offers the smallest PCB footprint and best thermal performance among industrial-grade variants, making it optimal for space-constrained, high-volume SMT production where TSSOP assembly is established.

The ATF750LVC-15XU supports up to 100 MHz maximum frequency with internal feedback (no external path) at 5V operation, and 83 MHz at 3V operation when using input-pin clocking. These values derive from measured tPS (clock period) of 10 ns and tWS (clock width) of 5 ns under specified load conditions - confirmed in Section 17 of the official datasheet.
Does the ATF750LVC-15XU support in-system programming (ISP)?
Yes, the ATF750LVC-15XU supports in-system programming via standard JTAG interface compliant with IEEE 1149.1. Programming voltage requirements (−2.0V to +14.0V on input pins during programming) and protocol details are defined in Section 4 and Section 22 of the datasheet - enabling field updates without device removal.
How many I/O pins on the ATF750LVC-15XU can operate as true bi-directional buffers?
Exactly 10 pins (Pins 12, 15–21) on the ATF750LVC-15XU are configured as I/O - each capable of input, output, or bi-directional operation with dedicated output-enable product terms and independent feedback paths into the logic array, as documented in Section 3.2 and Figure 10 of the datasheet.
Is the ATF750LVC-15XU RoHS-compliant and lead-free?
Yes, the ATF750LVC-15XU is manufactured in a green package meeting Pb/halide-free and RoHS compliance requirements, as explicitly stated in Section 23.1 of the datasheet. The 24X (TSSOP) package carries no lead content and conforms to JEDEC MO-153 AD standards.
What logic architecture does the ATF750LVC-15XU implement, and how does it relate to the 22V10?
The ATF750LVC-15XU implements Atmel's enhanced "750" architecture - a superset of the 22V10 with double the logic density, 20 flip-flops (vs. 10), 171 product terms (vs. 112), and added features including per-register D/T-type selection and pin-keeper circuits - all while maintaining architectural compatibility with ATV750B software tools and fuse maps.
