Product details
Overview
ATF750CL-15XU from Microchip Technology (formerly Atmel) is a low-power, electrically-erasable complex programmable logic device (CPLD) in a 24-pin TSSOP package, delivering 15 ns maximum pin-to-pin delay at 5V operation, 20 flip-flops (D- or T-type configurable), and 171 product terms - designed for battery-powered industrial control, legacy PLD replacement, and space-constrained logic consolidation.
For engineers reviewing the ATF750CL-15XU datasheet, ATF750CL-15XU pinout, ATF750CL-15XU application, or ATF750CL-15XU equivalent, key selection criteria include its 1 mA standby current, programmable pin-keeper circuits eliminating external pull-ups, dual clocking options (product-term or direct pin), and compatibility with ATV750B/BL and ATV750/L designs.
Technical Context
The ATF750CL-15XU implements a 22-input, 20-output CPLD architecture with fully independent feedback paths for all 20 registers and dedicated input routing per I/O pin. Its logic array provides two sum terms per output and supports variable product-term allocation (4–8 per sum term), enabling efficient state machine and combinatorial logic implementation.
It features asynchronous reset per flip-flop, synchronous preset for all registers, register preload via I/O pins, and power-up reset that forces all registers low. Clocking flexibility includes per-flip-flop selection between product-term-derived clocks and direct input pin (CLK/IN) clocking - critical for mixed-clock-domain designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pin-to-Pin Delay | 15 ns at 5V - guarantees deterministic timing for high-speed control loops and interface glue logic. |
| Standby Current | 0.12–0.15 mA (Commercial/Industrial) - enables multi-year battery operation in portable instrumentation. |
| Logic Density | 20 flip-flops + 171 product terms - replaces up to 10 standard 74-series ICs in compact 24-pin footprint. |
| 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 and outdoor embedded controllers. |
| Data Retention | 20 years - ensures long-term reliability in unattended field-deployed equipment. |
| ESD Protection | 2000V HBM - robust handling during board assembly and field service. |
Pinout & Package
ATF750CL-15XU uses a 24-lead Thin Shrink Small Outline Package (TSSOP), 4.4 mm body width, JEDEC MO-153 AD compliant, with 0.65 mm pitch and gull-wing leads. Pin 1 identifier is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLK/IN) | Clock Input / Logic Input | Selectable as global clock source or general-purpose input; enables direct-pin clocking for individual flip-flops. |
| 2–12, 23 | Logic Inputs | 12 dedicated input-only pins; support asynchronous reset, preset, and product-term generation. |
| 13 (GND) | Ground | Primary ground reference; decoupling capacitor must be placed adjacent to this pin. |
| 14–22 | Bi-directional I/O | 10 pins configurable as inputs, outputs, or bidirectional buffers; each has programmable pin-keeper and output enable term. |
| 24 (VCC) | +5V Supply | Single 5V supply rail; requires local 0.1 µF ceramic decoupling capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Pin-keeper Circuits | Eliminates need for external pull-up resistors on unused inputs/I/Os, reducing BOM count and DC power loss. |
| Dual Clocking Architecture | Each flip-flop independently selects between product-term clock (flexible timing) or CLK/IN pin clock (low-jitter, high-speed). |
| Per-Flip-Flop Asynchronous Reset | Enables precise initialization of individual state machine stages without global reset propagation delay. |
| Register Preload Function | Allows forcing any register state (high/low) asynchronously via I/O pins - simplifies boundary-scan testing and debug. |
| Power-up Reset | Guarantees all 20 registers initialize to low state at VCC > 2.0 V, ensuring deterministic startup in safety-critical logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15XU | Standard-power variant: 125–190 mA ICC standby vs. 0.12–0.15 mA for ATF750CL-15XU. | Suitable where higher speed margin is needed but battery life is not constrained. | Select when system power budget allows >100× higher standby current and thermal management supports higher dissipation. |
| ATF750CL-15PU | Same logic functionality and 15 ns speed grade, but in 24-lead PDIP package (7.62 mm width) instead of TSSOP. | Preferred for through-hole prototyping, manual rework, or legacy wave-solder assembly lines. | Choose for hand-soldered development boards or production environments lacking fine-pitch SMT capability. |
