Product details
Overview
ATF750C-7SX from Atmel is a high-speed, electrically-erasable complex programmable logic device (CPLD) in 24-pin SOIC package, featuring 20 D/T-type flip-flops, 171 product terms, 20 sum terms, and 7.5 ns pin-to-pin delay at 5V operation. It serves as a reprogrammable logic replacement for 22V10-based designs in industrial control and legacy system upgrades.
For engineers reviewing the ATF750C-7SX datasheet, ATF750C-7SX pinout, ATF750C-7SX application, or ATF750C-7SX equivalent, key selection criteria include its 5V CMOS compatibility, programmable pin-keeper circuits, dual clocking options (product-term or input-pin), and support for synchronous preset and individual asynchronous reset per register.
Technical Context
The ATF750C-7SX implements a 22-input, 10 I/O + 12 dedicated input architecture with fully independent feedback paths for all 20 registers. Its logic array provides 42 array inputs and supports variable product-term allocation (4–8 per sum term), enabling efficient state machine encoding and buried logic implementation.
It features two distinct clocking modes: product-term-controlled clocks (with tCO = 3–7.5 ns) and direct input-pin clocks (tCOS = 0–6.5 ns), allowing mixed-clock-domain register coexistence. All 20 flip-flops feed back into the array, and 10 are available as bi-directional I/Os with individual output-enable product terms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 20 flip-flops + 20 sum terms = ~100 usable macrocells; replaces multiple 22V10 devices in single-package logic consolidation. |
| Propagation Delay | 7.5 ns max pin-to-pin delay at 5V; enables reliable operation up to 95 MHz with external feedback. |
| Power Supply | 5V ±5%; ICC = 125–180 mA standby (commercial temp); supports standard TTL/CMOS interface levels. |
| Input/Output Pins | 22 logic pins: 12 dedicated inputs + 10 bi-directional I/Os; all support programmable pin-keeper circuits to eliminate external pull-ups. |
| Clock Architecture | Dual-mode: per-register product-term clock (tCF = 1–7.5 ns) or direct pin clock (tCFS = 0–5.5 ns); enables heterogeneous timing domains. |
| Data Retention | 20-year nonvolatile storage; retains configuration without power; qualified for industrial temperature range (−40°C to +85°C). |
| ESD Protection | 2000V HBM; sufficient for board-level handling without special ESD controls during assembly. |
Pinout & Package
ATF750C-7SX is housed in a 24-lead, 0.300" wide plastic gull-wing small outline (SOIC) package (24S), compliant with JEDEC MS-012. Pin 1 is marked by beveled corner; body width is 7.4–7.6 mm, lead pitch is 1.27 mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Primary clock input or general-purpose input; selectable as global clock source for pin-clocked registers. |
| 2–12 | IN | Dedicated logic inputs; each feeds array directly; support pin-keeper for floating-state hold. |
| 13 | GND | Ground reference for VCC and signal integrity; decoupling capacitor must be placed adjacent. |
| 14–23 | I/O | Bi-directional buffers; each has independent OE product term and internal feedback path to array. |
| 24 | VCC | +5V supply; requires local 0.1 µF ceramic decoupling; voltage tolerance ±5%. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable D/T Flip-flops | Each of 20 registers configurable as D- or T-type; enables JK/SR synthesis and optimal product-term usage per state element. |
| Pin-keeper Circuits | Eliminates need for external pull-up resistors on unused I/Os; reduces board space, BOM count, and DC leakage current. |
| Asynchronous Reset per Register | 20 independent reset lines allow selective initialization of state machine partitions without global reset propagation delay. |
| Synchronous Preset | Single common preset line forces all 20 registers high on next clock edge; simplifies known-state startup sequences. |
| Preload Function | Asynchronous register loading via 10.25–10.75V pulse on pin 8 (SOIC lead 10); enables deterministic test vector injection during boundary scan or functional test. |
Applications
| Industrial PLC I/O Expansion | Legacy System 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-7PX | Same logic architecture and speed grade (7.5 ns), but in 24-lead PDIP package; no surface-mount capability. | Used where through-hole assembly or socket-based prototyping is required; lacks SOIC thermal performance and density. | Select ATF750C-7PX only for breadboard evaluation or legacy through-hole production lines. |
| ATF750C-10JU | Slower 10 ns speed grade in 28-lead PLCC package; higher pin count allows more I/O routing flexibility but larger footprint. | Suitable for designs needing >10 I/Os or requiring PLCC's mechanical robustness in vibration-prone environments. | Choose ATF750C-10JU when additional I/Os or industrial-grade packaging outweighs speed and size requirements. |
Compared with ATF750C-7PX and ATF750C-10JU, the ATF750C-7SX offers optimal balance of speed (7.5 ns), compact SOIC footprint (24S), and industrial temperature rating (−40°C to +85°C), making it ideal for space-constrained embedded control where reprogrammability and pin-keeper efficiency are critical.

FAQ
What is the maximum operating frequency of the ATF750C-7SX?
The ATF750C-7SX supports up to 95 MHz maximum frequency with external feedback (1/(tSS + tCOS)), 133 MHz with internal feedback, and 142 MHz in no-feedback configurations. These values assume 5V ±5% supply and operation within 0°C to 70°C commercial range; derating applies for industrial temperatures.
Does the ATF750C-7SX require external pull-up resistors on unused I/O pins?
No-the ATF750C-7SX includes programmable pin-keeper circuits on all input and I/O pins. When enabled via compiler settings (e.g., V750CPPK for SOIC), these circuits hold the last driven logic state, eliminating floating inputs and removing the need for external pull-up resistors and their associated power consumption.
Can the ATF750C-7SX replace an ATV750B in an existing design?
Yes-the ATF750C-7SX is a direct functional replacement for the ATV750B/BL. It supports cross-programming using the ATV750B JEDEC file (V750B mode), preserving pinout, timing, and fuse map compatibility while offering enhanced features like T-type registers and pin-clocking if the design is recompiled for ATF750C.
What package type does the ATF750C-7SX use, and what are its key mechanical dimensions?
The ATF750C-7SX uses a 24-lead plastic gull-wing small outline (SOIC) package (24S). Key dimensions: body width 7.4–7.6 mm, overall width 15.2–15.6 mm, lead pitch 1.27 mm, and thickness 2.16–2.65 mm. It complies with JEDEC MS-012 and is RoHS-compliant.
How does the power-up reset function work in the ATF750C-7SX?
The ATF750C-7SX performs automatic register reset at power-up when VCC crosses VRST (2.0–4.5 V). All 20 registers initialize to low state after tPR (600–1000 ns). This ensures deterministic state machine startup, provided VCC rise is monotonic and input setup times are met before first clock edge-critical for safety-critical embedded control.
