Product details
Overview
ATF750CL-15SU from Atmel is a low-power, electrically-erasable complex programmable logic device (CPLD) with 20 registered outputs, 42 array inputs, and 171 total product terms. It features D- or T-type flip-flops, pin-keeper circuits, and 15 ns maximum pin-to-pin delay at 5V operation. Used in industrial control logic, legacy system upgrades, and battery-powered embedded state machines.
For engineers reviewing the ATF750CL-15SU datasheet, ATF750CL-15SU pinout, ATF750CL-15SU application, or ATF750CL-15SU equivalent, key selection criteria include its 1 mA standby current, 24-pin SOIC package, -40°C to +85°C industrial temperature range, and compatibility with ATV750B/BL and ATV750/L designs.
Technical Context
The ATF750CL-15SU implements a high-density PLD architecture derived from the 22V10, extended with 20 individually configurable D/T flip-flops, 20 sum terms, and dual-clocking options (product-term or direct input pin). All 20 flip-flops feed back into the logic array, enabling buried state machines without external routing.
It supports programmable pin-keeper circuits on all I/Os to prevent floating inputs and eliminate external pull-ups, and includes asynchronous reset per flip-flop plus one global synchronous preset line. Power-up reset ensures deterministic register initialization at VRST = 2.0–4.5 V.
Key Specifications

|---|---|
| Max Pin-to-pin Delay | 15 ns at 5V - guarantees timing closure for 50 MHz state machines with internal feedback |
| Standby Current | 0.12–0.15 mA - enables battery-backed operation and reduces system quiescent power |
| Logic Density | 171 product terms, 20 sum terms, 20 flip-flops - replaces multiple 22V10s or discrete glue logic |
| Operating Voltage | 5V ±5% - compatible with standard TTL/CMOS 5V systems without level translation |
| Temperature Range | -40°C to +85°C - qualified for industrial environments including motor drives and PLC I/O modules |
| ESD Protection | 2000V HBM - robust against handling and board-level electrostatic discharge |
| Data Retention | 20 years - ensures long-term configuration stability in unattended equipment |
Pinout & Package
ATF750CL-15SU is housed in a 24-lead plastic gull-wing small outline (SOIC) package (24S), 0.300" body width, JEDEC MS-012 compliant. Pin 1 is marked by notch or dot; pin 12 is GND, pin 13 is VCC, and pin 1 is CLK/IN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Configurable as clock input or general logic input; selects clock source per flip-flop when used as clock |
| 2–11, 14–24 | IN / I/O | 22 logic pins: 12 dedicated inputs, 10 bi-directional I/Os with programmable output enable and pin-keeper |
| 12 | GND | Ground reference for logic and power; decoupling required within 10 mm of pin |
| 13 | VCC | +5V supply; requires local 0.1 µF ceramic bypass capacitor adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Pin-keeper Circuits | Eliminates need for external pull-up resistors on unused I/Os, reducing BOM count and DC leakage |
| D- or T-type Flip-flop per Register | Enables efficient implementation of JK/SR latches and counters without consuming extra product terms |
| Dual Clocking Architecture | Each flip-flop accepts either product-term-derived or direct pin-driven clock, supporting mixed-speed logic domains |
| Asynchronous Reset per Flip-flop | Allows independent reset of state machine partitions without global signal contention or timing skew |
| Power-up Reset Function | Guarantees all registers initialize to low state at VRST crossing, critical for deterministic boot behavior |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15SU | Higher standby current (125–180 mA vs. 0.12 mA); same 15 ns speed grade and SOIC-24 package | Suitable only for AC-powered systems where low quiescent power is not required | Select when legacy ATF750C design files are reused without modification and thermal budget allows higher ICC |
| ATV750L-15SU | UV-erasable (not electrically erasable); no pin-keeper; no T-type flip-flops; JEDEC-compatible but non-reprogrammable in-system | Limited to factory-programmed, fixed-function roles; no field updates or debug iteration | Select only for cost-sensitive, high-volume production where reprogramming capability is unnecessary |
Compared with ATF750C-15SU and ATV750L-15SU, the ATF750CL-15SU uniquely delivers electrically erasable reprogrammability, sub-mA standby power, and pin-keeper circuitry - making it the only choice for battery-operated, field-upgradable, or noise-sensitive industrial logic applications.

FAQ
What is the standby current specification for ATF750CL-15SU?
The ATF750CL-15SU has a typical standby current of 0.12 mA at 5V and 25°C under commercial conditions, and up to 0.15 mA under industrial temperature extremes. This ultra-low ICC enables use in battery-backed systems where multi-year operation is required without recharge or replacement. The ATF750CL-15SU achieves this via optimized CMOS gate design and selective power gating of unused logic blocks.
Is ATF750CL-15SU pin-compatible with ATV750L-15SU?
Yes - the ATF750CL-15SU uses identical 24-pin SOIC (24S) packaging and pinout as the ATV750L-15SU, including CLK/IN on pin 1, GND on pin 12, and VCC on pin 13. However, the ATF750CL-15SU adds pin-keeper functionality and T-type flip-flop support, which require updated JEDEC programming files generated in Atmel WinCUPL's "V750CPPK" or "V750" device modes.
Does ATF750CL-15SU support in-system programming?
Yes - the ATF750CL-15SU supports in-system programming via standard JEDEC-compliant programmers using the 14,504-fuse configuration. Its electrically erasable EEPROM-based architecture allows full reprogramming without removal from the PCB, enabling field firmware updates and design iteration. Programming voltage is 10.25–10.75 V applied to pin 8 during preload cycles.
What is the maximum operating frequency of ATF750CL-15SU with internal feedback?
The ATF750CL-15SU achieves a maximum operating frequency of 62 MHz when using internal feedback paths (1/(tSF + tCF)), as specified in the AC Characteristics table for the -15 speed grade. This enables reliable implementation of synchronous state machines running at 16-bit counter rates or UART baud rate generators up to 3.125 Mbps with timing margin.
How does the pin-keeper feature function on ATF750CL-15SU?
The pin-keeper circuit on each I/O pin of the ATF750CL-15SU maintains the last driven logic state (high or low) when the pin becomes floating, preventing undefined inputs that cause shoot-through current or metastability. Enabled via WinCUPL device selection (e.g., V750CPPK), it eliminates external pull-up resistors and reduces system power consumption by up to 1.2 mW per unused pin at 5V.
