Product details
Overview
ATF750LVC-15SU from Microchip Technology (formerly Atmel) is a high-performance, electrically-erasable complex programmable logic device (CPLD) in a 24-pin SOIC package. It implements up to 20 D- or T-type flip-flops, 42 array inputs, and 20 sum terms with 171 total product terms; supports 3.0–5.5V operation; delivers ≤15 ns pin-to-pin delay at 3V and ≤10 ns at 5V; and is used in legacy industrial control logic replacement and FPGA companion glue logic.
For engineers reviewing the ATF750LVC-15SU datasheet, ATF750LVC-15SU pinout, ATF750LVC-15SU application, or ATF750LVC-15SU equivalent, key selection criteria include its 24-pin SOIC footprint, dual clocking modes (product-term or input-pin), programmable pin-keeper circuits, 20-year data retention, and compatibility with ATV750B/ATV750 software toolchains.
Technical Context
The ATF750LVC-15SU implements a 20-register, 20-output logic array with fully independent feedback paths and per-flip-flop clock source selection-either from dedicated product terms or directly from Pin 1 (CLK/IN). Its architecture provides two sum terms per output, variable product-term allocation (4–8 per sum term), and individual asynchronous reset for each flip-flop.
It features programmable pin-keeper circuits on all I/O pins to prevent floating states without external pull-ups, synchronous preset for all registers, and security fuse protection against unauthorized configuration copying. The device operates across commercial (0°C to 70°C) and industrial (−40°C to +85°C) temperature ranges with 2000V HBM ESD rating and 1000 erase/write cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 20 flip-flops, 20 sum terms, 42 array inputs, 171 product terms - enables full state machines and multi-function glue logic in one 24-pin device. |
| Propagation Delay | ≤10 ns (5V), ≤15 ns (3V) pin-to-pin - ensures timing-critical control path compliance in legacy 50–70 MHz systems. |
| Supply Voltage | 3.0 V to 5.5 V - supports direct interface with both 3.3V and 5V TTL/CMOS buses without level-shifting. |
| Operating Temperature | −40°C to +85°C - qualified for industrial embedded control, motor drives, and instrumentation environments. |
| Data Retention | 20 years - guarantees long-term configuration stability in unattended or maintenance-limited deployments. |
| ESD Protection | 2000 V HBM - meets IEC 61000-4-2 Level 2 for robustness in factory-floor and field-replaceable modules. |
| Erase/Write Cycles | 1000 cycles - sufficient for prototyping, firmware updates, and field reconfiguration during product lifecycle. |
Pinout & Package
ATF750LVC-15SU is supplied in a 24-lead, 0.300″ wide plastic gull-wing small outline (SOIC) package (JEDEC MS-012AC), pin-compatible with industry-standard 24-pin PLD footprints. Package dimensions: 15.2–15.6 mm width × 10.0–10.65 mm length × ≤2.65 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLK/IN) | Input Clock or Logic Input | Selectable as global clock source for input-pin clocking mode or general-purpose logic input. |
| 2–11, 13–22 | IN or I/O | 20 bidirectional pins; each configurable as input, output, or I/O with independent enable and feedback path. |
| 12 | GND | Ground reference for analog and digital sections; decoupling required near VCC pin. |
| 23 | VCC | 3.0–5.5 V power supply; requires local 0.1 µF ceramic decoupling capacitor. |
| 24 | GND | Second ground pin for improved noise immunity and current return path separation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual clocking architecture | Each flip-flop independently selectable for product-term or direct input-pin (Pin 1) clocking - enables mixed-clock-domain logic (e.g., slow control + fast interface) in one device. |
| Programmable pin-keeper | Eliminates need for external pull-up resistors on unused I/Os - reduces BOM count, PCB area, and static power by >100 µA per pin. |
| Asynchronous per-flip-flop reset | 20 independent reset lines allow selective initialization of logic blocks without global system reset - critical for modular state machine recovery. |
| Security fuse | Single fuse prevents read-back of configuration bitstream - protects IP in production systems where reverse engineering risk exists. |
| RoHS-compliant green packaging | Pb/halide-free SOIC (24S) construction - satisfies EU WEEE/RoHS and China RoHS requirements for industrial OEM shipments. |
Applications
| Industrial PLC I/O Expansion | Legacy System Glue Logic Replacement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15PU | Same logic architecture but PDIP package (24P3); lacks pin-keeper circuitry; rated only for commercial temp (0°C to 70°C). | Suitable for lab prototypes and non-industrial environments where through-hole assembly and lower cost are prioritized. | Choose when board-level rework tolerance, socketing, or legacy through-hole manufacturing is required. |
| ATF16V8B-15PU | 8 macrocells vs. 20 flip-flops; no T-type register support; 25 ns max delay; no pin-keeper; 5V-only operation. | Limited to simpler combinatorial logic and basic counters; insufficient for multi-state machine or high-density glue logic. | Select only for minimal replacements where logic depth and register count are below ATF750LVC-15SU's capability envelope. |
Compared with ATF750C-15PU and ATF16V8B-15PU, the ATF750LVC-15SU delivers twice the register count, 3.3V/5V dual-voltage operation, industrial temperature range, and pin-keeper functionality - making it the sole option among these three for new industrial designs requiring long-term reliability and mixed-voltage interoperability.

FAQ
What is the maximum operating frequency of the ATF750LVC-15SU?
The ATF750LVC-15SU achieves up to 90 MHz maximum frequency with no feedback (1/tP), 86 MHz with internal feedback (1/(tSF + tCF)), and 71 MHz with external feedback (1/(tS + tCO)) under 5V operation. At 3V, those values drop to 71 MHz, 62 MHz, and 50 MHz respectively - all verified in the AC characteristics table of the official datasheet.
Does the ATF750LVC-15SU support 3.3V-only operation?
Yes, the ATF750LVC-15SU is fully specified for 3.0–5.5V operation, including guaranteed performance at 3.3V. Its 3V AC characteristics (e.g., 15 ns max tPD, 55 MHz fMAXS) are explicitly published in the datasheet, and DC parameters like VOL ≤0.5V at IOL = 12 mA are validated down to VCC = 3.0V.
Can the ATF750LVC-15SU replace a 22V10 in an existing design?
Yes - the ATF750LVC-15SU is architecturally compatible with the 22V10 and functions as a superset: same 24-pin SOIC footprint, JEDEC file compatibility, and identical programming protocols. It adds 10 extra flip-flops, enhanced clocking options, and pin-keeper circuits - enabling drop-in upgrades without layout changes.
What programming hardware and software support the ATF750LVC-15SU?
The ATF750LVC-15SU is supported by Atmel's legacy WinCUPL and Synario development tools. Programming requires a standard JTAG or ISP-compatible programmer (e.g., Atmel ICE, third-party CUPL programmers). Configuration files use JEDEC JED format, and security fuse programming is handled via the same toolchain.
Is the ATF750LVC-15SU pin-keeper function enabled by default?
No - the pin-keeper circuit is disabled by default. It must be explicitly enabled during compilation using the "ATF750LVC (PPK)" device selection in WinCUPL or Synario. When enabled, it holds unused I/O pins at their last driven state, eliminating floating inputs and removing the need for external pull-up resistors.
