Product details
Overview
ATF750C-10PU from Atmel is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) in a 24-pin PDIP package, delivering 7.5 ns pin-to-pin delay at 5V operation, 20 registered outputs with individually configurable D/T-type flip-flops, and 171 total product terms for advanced state machine implementation. It serves as a speed- and density-upgraded replacement for ATV750B/BL and ATV750/L in industrial control logic, bus interface glue logic, and legacy system upgrades.
For engineers reviewing the ATF750C-10PU datasheet, ATF750C-10PU pinout, ATF750C-10PU application, or ATF750C-10PU equivalent, this device supports dual clocking modes (product-term and input-pin), programmable pin-keeper circuits to eliminate external pull-ups, and full industrial temperature range (-40°C to +85°C) operation - critical for deterministic timing in embedded control and reprogrammable logic consolidation.
Technical Context
The ATF750C-10PU implements a 22-input × 20-output macrocell architecture with 42 array inputs, 20 sum terms, and 20 flip-flops - all individually configurable as D- or T-type. Its logic array supports both combinatorial and registered output paths, with dedicated product terms per flip-flop for asynchronous reset, synchronous preset, and clock enable.
It features two independent clocking options: global CLK pin (Pin 1) or per-flip-flop product-term clocks, enabling mixed-clock-domain designs. All 20 flip-flop outputs feed back into the logic array, allowing buried registers and full utilization of 171 product terms without I/O pin constraints.
Key Specifications

Pinout & Package
ATF750C-10PU is housed in a 24-lead plastic dual-inline package (PDIP, package code 24P3), 0.300" wide, with industry-standard pinout compatible with legacy 22V10 and ATV750 devices.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK / IN | Global clock input or general-purpose logic input; selectable via fuse configuration. |
| 2–12, 23 | IN | 11 dedicated input pins - provide primary array inputs for combinational logic functions. |
| 13 | GND | Ground reference for power and signal integrity; decoupling required near VCC pin. |
| 14–22 | I/O | 10 bi-directional I/O pins - each supports registered or combinatorial output, with programmable pin-keeper. |
| 24 | VCC | +5V supply pin - 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 I/Os, reducing BOM count and static power draw. |
| Dual Clocking Architecture | Per-macrocell product-term clocks + global CLK pin - enables multi-rate state machines without external clock dividers. |
| 20 Independent Flip-flops | All 20 register outputs feed back into logic array - supports fully buried logic with zero I/O pin overhead. |
| Asynchronous Reset per Macrocell | Individual reset product term per flip-flop - allows selective initialization in complex sequencers. |
| Synchronous Preset Line | Single global preset signal for all 20 registers - simplifies power-on initialization and test-mode entry. |
| Preload Capability | Asynchronous register loading via I/O pins during 10.5V programming cycle - accelerates functional test coverage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic consolidation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-10JU | Same core logic, but in 28-pin PLCC (28J) package - larger footprint, better thermal dissipation. | Preferred for high-reliability industrial PCBs requiring surface-mount assembly and enhanced vibration resistance. | Select when board space permits PLCC and long-term solder joint reliability is prioritized over through-hole ease-of-use. |
| ATF750CL-15PU | Low-power variant (ATF750CL) with 15 ns speed grade and 1 mA standby current - not pin-compatible with -10PU. | Suitable for battery-backed or thermally constrained applications where 15 ns timing suffices. | Choose only if system clock frequency ≤50 MHz and power budget mandates sub-2 mA quiescent current. |
Compared with ATF750C-10JU, the ATF750C-10PU offers identical logic functionality in a through-hole PDIP package ideal for prototyping and repair, while ATF750CL-15PU trades speed for ultra-low power - making ATF750C-10PU the optimal balance of performance, industrial qualification, and mechanical serviceability.

FAQ
What is the maximum operating frequency supported by the ATF750C-10PU?
The ATF750C-10PU supports up to 95 MHz in external feedback mode (1/(tSS + tCOS)) and 142 MHz in no-feedback mode (1/tPS), based on its 7.5 ns propagation delay and 7 ns minimum clock period. These values assume proper PCB layout, 5V ±5% supply, and industrial temperature conditions - actual system frequency depends on logic depth and routing delays within the programmed design.
Does the ATF750C-10PU require external pull-up resistors on unused I/O pins?
No. The ATF750C-10PU includes programmable pin-keeper circuits on all input and I/O pins. When enabled via compiler settings (e.g., V750CPPK in WinCUPL), these circuits actively hold the last driven logic state, eliminating floating inputs and removing the need for external pull-up resistors - reducing BOM cost and board area.
Is the ATF750C-10PU pin-compatible with the older ATV750B-10PU?
Yes. The ATF750C-10PU is a direct replacement for ATV750B-10PU and ATV750-10PU in the same 24-pin PDIP package, maintaining identical pinout, voltage levels, and JEDEC file compatibility. It adds T-type flip-flops and pin-clocking capability while preserving backward compatibility for drop-in upgrades.
What programming voltage is required for the ATF750C-10PU?
The ATF750C-10PU requires 10.25V to 10.75V on Pin 8 during programming for register preload and fuse programming. Standard 5V operation is used for normal logic function. Programming must be performed using a compatible programmer (e.g., Atmel-ICE or third-party tools supporting V750 JEDEC files) with appropriate timing per the AC characteristics table.
How does the power-up reset feature function in the ATF750C-10PU?
The ATF750C-10PU automatically resets all 20 registers to low state when VCC crosses the 2.0–4.5 V power-up reset threshold (VRST). This occurs ~600–1000 ns after VCC rise (tPR), ensuring deterministic state machine initialization. For reliable operation, VCC must rise monotonically, and clock inputs must remain stable during tPR to meet setup/hold requirements before first clock edge.
