Product details
Overview
ATF750CL-15PC 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-flop configuration per register, pin-to-pin delay of 15 ns at 5V, and operates across industrial temperature range (–40°C to +85°C). It serves as a high-density replacement for 22V10-based logic in embedded control, bus interface, and state machine applications.
For engineers reviewing the ATF750CL-15PC datasheet, ATF750CL-15PC pinout, ATF750CL-15PC application, or ATF750CL-15PC equivalent, key selection criteria include its 1 mA standby current, programmable pin-keeper circuits, dual clocking options (product-term or direct input pin), 20-year data retention, and compatibility with ATV750B/BL and ATV750/L designs.
Technical Context
The ATF750CL-15PC implements a 20-register architecture with independent feedback paths and individual asynchronous reset per flip-flop. Its logic array provides two sum terms per output and supports variable product-term allocation (4–8 per sum term), enabling efficient implementation of complex combinatorial and sequential logic.
It supports both product-term clocking and direct input pin clocking (Pin 1), allowing mixed-clock-domain operation within a single device. All 20 registers feed back into the array, and 10 are available as bi-directional I/Os - each with dedicated output-enable product terms and programmable pin-keeper functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pin-to-pin Delay | 15 ns at 5V - guarantees deterministic timing for high-speed synchronous logic in industrial control systems. |
| Standby Current | 0.12–0.15 mA (typ/max) - enables battery-backed operation and reduces system-level power budget. |
| Logic Density | 171 product terms, 20 sum terms, 20 flip-flops - replaces multiple discrete SSI/MSI logic ICs in compact PCB layouts. |
| I/O Configuration | 12 dedicated inputs + 10 bi-directional I/Os - supports flexible bus interfacing and mixed signal routing without external buffers. |
| Data Retention | 20 years - ensures long-term reliability in unattended or maintenance-limited deployments. |
| ESD Protection | 2000 V HBM - meets industrial IEC 61000-4-2 robustness requirements without added protection circuitry. |
| Erasure Cycles | 1000 write/erase cycles - supports field firmware updates and design iteration during prototyping and production. |
Pinout & Package
ATF750CL-15PC is packaged in a 24-lead plastic dual-inline package (PDIP), 0.300" wide (24P3), with standard 2.54 mm lead pitch. Pin 1 is marked by notch or dot; Pin 12 is GND, Pin 13 is VCC (5V ±10%), Pin 1 is CLK/IN, Pins 2–11 and 14–24 serve as IN/I/O terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | CLK/IN | Primary clock input or general-purpose logic input; supports direct pin clocking for selected flip-flops. |
| Pins 2–11 | IN | Dedicated input-only pins; all 10 can be used as inputs to the logic array or as feedback sources. |
| Pins 14–24 | I/O | Bi-directional I/Os; each has programmable output enable, pin-keeper, and internal feedback path. |
| Pin 12 | GND | Ground reference for logic and power; required for stable operation and noise immunity. |
| Pin 13 | VCC | +5V supply (±10%); powers core logic, I/O buffers, and internal programming circuitry. |
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 current. |
| D- or T-type Flip-flop per Register | Enables efficient JK/SR emulation and optimized product-term usage in state machines and counters. |
| Dual Clocking Architecture | Allows mixing of product-term clocks (flexible edge-triggered control) and direct pin clocks (minimal latency). |
| Power-up Reset | Automatically resets all registers to low state at VRST (2.0–4.5 V), ensuring deterministic startup in control systems. |
| Security Fuse | Prevents unauthorized readback of JEDEC fuse pattern, protecting proprietary logic configurations. |

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 and pinout, but higher 125–190 mA standby current (vs. 0.12–0.15 mA). | Not suitable for battery-powered or thermally constrained designs requiring ultra-low quiescent power. | Select ATF750CL-15PC when <1 mA standby is mandatory; choose ATF750C-15PU only if speed margin is prioritized over power. |
| ATV750L-15PU | Non-erasable OTP version; lacks reprogrammability, pin-keeper, T-type flip-flops, and direct pin clocking. | Limited to fixed-function, one-time-programmed roles where field updates or design iteration are unnecessary. | Use ATV750L-15PU only for cost-sensitive, high-volume production where logic is fully validated and unchanging. |
Compared with ATF750C-15PU, the ATF750CL-15PC delivers 1000× lower standby current while retaining identical logic density and timing; versus ATV750L-15PU, it adds full in-system reprogrammability, enhanced clocking flexibility, and active power management - critical for development agility and long-life medical/industrial systems.

FAQ
What is the operating voltage range for ATF750CL-15PC?
The ATF750CL-15PC operates at 5V ±10%, with absolute maximum ratings of –2.0V to +7.0V on any pin. It is not rated for 3.3V operation; using it outside the 4.5–5.5V range may cause functional failure or reduced reliability. The ATF750CL-15PC datasheet specifies all DC and AC parameters under this 5V condition, including its 0.12–0.15 mA standby current and 15 ns pin-to-pin delay.
Does ATF750CL-15PC support in-system programming?
Yes, the ATF750CL-15PC supports in-system programming via standard JEDEC file loading using compatible programmers (e.g., Atmel-ICE, third-party tools supporting V750 format). Its electrically-erasable EEPROM-based architecture allows full reconfiguration without removal from the PCB. The ATF750CL-15PC requires 10.25–10.75V on Pin 8 during preload cycles, but normal programming uses standard 5V VCC and JTAG-compatible interfaces.
How many I/O pins on ATF750CL-15PC can be used bidirectionally?
Exactly 10 I/O pins (Pins 14–24, excluding Pin 12/GND and Pin 13/VCC) are configurable as bi-directional I/Os on the ATF750CL-15PC. Each has independent output-enable control via dedicated product terms, internal feedback paths, and programmable pin-keeper circuits. The remaining 12 pins (Pin 1 + Pins 2–11) are input-only, providing 42 total array inputs when combined with feedback signals.
Is ATF750CL-15PC pin-compatible with ATF750C-15PU?
Yes, the ATF750CL-15PC and ATF750C-15PU share identical 24P3 PDIP pinout, electrical signaling, and logic architecture. They differ only in standby current (0.12–0.15 mA vs. 125–190 mA) and internal power management circuitry. No PCB layout change is needed when substituting ATF750CL-15PC for ATF750C-15PU - the ATF750CL-15PC functions as a drop-in low-power upgrade.
What software tools support ATF750CL-15PC design and programming?
Atmel WinCUPL is the native compiler for ATF750CL-15PC, supporting ABEL and CUPL source entry, pin-keeper configuration, D/T flip-flop assignment, and JEDEC file generation. Third-party tools like Lattice ispLEVER Classic (via V750 cross-mode) and older Data I/O PS-2000 programmers also support ATF750CL-15PC through JEDEC file compatibility. The ATF750CL-15PC requires no special drivers beyond standard parallel-port or USB-based programmer firmware.
