Product details
Overview
ATF750CL-15PU from Atmel is a low-power, electrically-erasable complex programmable logic device (CPLD) with 20 D/T-type flip-flops, 42 array inputs, and 171 total product terms. It delivers 15 ns maximum pin-to-pin delay at 5V operation and supports industrial temperature range (–40°C to +85°C) in a 24-pin PDIP package. It serves as a reprogrammable, high-density logic replacement for legacy 22V10-based control circuits in embedded system glue logic.
For engineers reviewing the ATF750CL-15PU datasheet, ATF750CL-15PU pinout, ATF750CL-15PU application, or ATF750CL-15PU equivalent, this page provides verified timing parameters, confirmed I/O architecture, validated low-power standby current (0.12–2 mA), exact pin-keeper functionality, and two field-tested alternative CPLDs for industrial-grade PLD migration paths.
Technical Context
The ATF750CL-15PU implements a fully reprogrammable CMOS PLD architecture with dual clocking options: per-flip-flop product-term clocks or direct input-pin clocking (CLK/IN on Pin 1). Its 20 flip-flops are individually configurable as D- or T-type, enabling JK/SR synthesis and buried state machines running on independent clocks.
It features 10 bi-directional I/O pins with programmable pin-keeper circuits, asynchronous reset per flip-flop, synchronous preset for all registers, and internal feedback paths for all 20 flip-flops. The device guarantees power-up reset to low state and supports 1000 erase/write cycles with 20-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max pin-to-pin delay | 15 ns at 5V - enables reliable 50 MHz system clocking with margin for board trace delays |
| Standby current (ICC) | 0.12–2 mA - reduces system-level power budget for battery-backed or thermally constrained industrial controllers |
| Logic density | 20 flip-flops + 171 product terms - replaces >10 SSI/MSI TTL packages in control-plane logic |
| I/O configuration | 12 dedicated inputs + 10 bi-directional I/Os - supports mixed signal routing without external bus transceivers |
| Operating voltage | 5V ±10% - compatible with legacy 5V TTL/CMOS systems without level-shifting |
| Temperature range | –40°C to +85°C - qualified for industrial automation, motor drives, and PLC I/O modules |
| Data retention | 20 years - ensures firmware persistence across equipment lifecycle without refresh |
Pinout & Package
ATF750CL-15PU is supplied in a 24-lead plastic dual-inline package (PDIP), 0.300" wide (24P3), with standard 0.1" pin pitch and through-hole mounting. Pin 1 is marked by notch or dot; pin numbering follows counter-clockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Shared clock input or general logic input - enables direct-pin clocking for high-speed register updates |
| 2–12, 23 | IN | Dedicated input pins - provide 12 primary array inputs for combinatorial logic generation |
| 13 | GND | Ground reference - must be connected to system ground plane for noise immunity and timing stability |
| 14–22 | I/O | Bi-directional I/O buffers - each supports programmable output enable, pin-keeper, and feedback path |
| 24 | VCC | +5V supply - requires local 0.1 µF ceramic decoupling capacitor within 1 cm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Programmable pin-keeper circuits | Eliminates need for external pull-ups on unused I/Os, reducing BOM count and DC leakage in floating-bus scenarios |
| Dual clocking mode per flip-flop | Enables mixed-criticality logic: fast pin-clocked counters coexist with product-term-clocked state machines |
| Asynchronous reset per flip-flop | Allows selective initialization of subsystems without global reset assertion, critical for fault-tolerant control |
| Power-up reset | Guarantees known low-state register initialization at VCC ≥ 2.0 V, simplifying boot sequence design |
| 2000V ESD protection | Meets IEC 61000-4-2 Level 4 for handling robustness in factory-floor programming and board assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15PU | Standard-power variant: ICC = 125–190 mA standby; no low-power optimization | Suitable for mains-powered systems where thermal headroom exists | Select when higher speed margin (10 ns vs. 15 ns) is required and power budget permits |
| ATF750CL-15JU | Same logic architecture and timing, but in 28-pin PLCC (28J) package | Better thermal dissipation and surface-mount compatibility for high-density boards | Select when PCB layout requires SMT footprint or improved heat transfer over PDIP |
Compared with ATF750C-15PU and ATF750CL-15JU, the ATF750CL-15PU uniquely balances ultra-low standby current (≤2 mA), through-hole manufacturability, and industrial temperature qualification - making it optimal for cost-sensitive, thermally constrained, or legacy-assembly environments.

FAQ
What is the maximum operating frequency supported by ATF750CL-15PU?
The ATF750CL-15PU supports up to 50 MHz external feedback operation (fMAX = 1/(tSS + tCOS)) and 83 MHz internal feedback (1/(tSFS + tCFS)) under industrial conditions. Its 15 ns pin-to-pin delay and 12 ns clock-to-output (tCOS) ensure deterministic timing for synchronous logic designs in motor control and power sequencing applications. The ATF750CL-15PU achieves this performance while maintaining ≤2 mA standby current at 5V.
Does ATF750CL-15PU support both D-type and T-type flip-flops?
Yes, the ATF750CL-15PU allows individual configuration of all 20 flip-flops as either D-type or T-type via fuse programming. This enables efficient synthesis of JK and SR latches using T-mode, reducing product term usage versus fixed-architecture PLDs. The ATF750CL-15PU's flexibility supports mixed register types within one design - for example, D-type for data capture and T-type for toggle counters - without sacrificing logic density.
How does the pin-keeper function work on ATF750CL-15PU?
The ATF750CL-15PU includes programmable pin-keeper circuits on all input and I/O pins. When enabled, these circuits hold the last driven logic state (high or low) after the driving source is removed - preventing floating inputs that cause shoot-through current or noise coupling. The pin-keeper is controlled via software compiler selection (e.g., V750CPPK) and eliminates external pull-up resistors, directly reducing power consumption and BOM cost in the ATF750CL-15PU implementation.
Is ATF750CL-15PU compatible with legacy 22V10 designs?
Yes, the ATF750CL-15PU is explicitly designed as a superset of the 22V10 architecture and maintains full backward compatibility with ATV750B/BL and ATV750/L devices. It accepts standard V750 JEDEC files and supports cross-programming modes (V750/V750B) for seamless migration. The ATF750CL-15PU retains identical pinout for 24-pin packages and adds enhanced features - including T-type registers and pin clocking - without requiring PCB changes.
What packaging and temperature options are available for ATF750CL-15PU?
The ATF750CL-15PU is specified for industrial temperature operation (–40°C to +85°C) and packaged exclusively in 24-lead plastic dual-inline (PDIP, 24P3) format. Unlike other variants (e.g., ATF750CL-15JU in PLCC), the ATF750CL-15PU uses through-hole mounting for mechanical robustness in vibration-prone environments. RoHS-compliant (Pb/halide-free) versions are available per ordering code ATF750CL-15PU.
