Product details
Overview
ATF750C-10SU-T from Atmel is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) in 24-pin SOIC package, delivering 7.5 ns pin-to-pin delay at 5V, 20 flip-flops (D/T-configurable), and 171 product terms for state-machine and combinatorial logic implementation in industrial control and legacy system upgrades.
For engineers reviewing the ATF750C-10SU-T datasheet, ATF750C-10SU-T pinout, ATF750C-10SU-T application, or ATF750C-10SU-T equivalent, this page provides verified timing specs, I/O flexibility, power-up reset behavior, pin-keeper functionality, and direct replacement guidance for ATV750B/L and ATV750/L devices.
Technical Context
The ATF750C-10SU-T implements a 22-input, 10-I/O, 20-register architecture with dual clocking options: per-flip-flop product-term clocks or direct input-pin clocking (Pin 1). Its 171 product terms feed 20 sum terms-two per output-with variable allocation (4–8 terms/sum term) enabling efficient buried logic and bi-directional I/O design.
Each of the 20 registers supports independent asynchronous reset, synchronous preset, and preload via dedicated I/O pins. The device features programmable pin-keeper circuits on all inputs/I/Os to prevent floating states, eliminating external pull-ups and reducing system noise and DC leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 7.5 ns max (input/feedback to non-registered output); enables sub-10 ns timing-critical glue logic. |
| Operating Voltage | 5V ±5%; compatible with legacy TTL/CMOS 5V systems without level-shifting. |
| Logic Density | 20 flip-flops + 20 sum terms + 171 product terms; replaces multiple 22V10-equivalent PLDs in one 24-pin package. |
| Flip-flop Type | Individually configurable as D-type or T-type; supports JK/SR synthesis and mixed-clock domain state machines. |
| Power Supply Current (ICC) | 125–180 mA standby (commercial temp); reflects active CMOS core consumption at full speed. |
| Data Retention | 20 years; ensures long-term configuration stability in unpowered storage or infrequently updated systems. |
| ESD Protection | 2000V HBM; meets industrial handling requirements without additional protection circuitry. |
| Erasure Cycles | 1000 write/erase cycles; supports field reprogramming during development and maintenance. |
Pinout & Package
ATF750C-10SU-T is housed in a 24-lead, 0.300" wide Plastic Gull Wing Small Outline (SOIC) package (24S), RoHS-compliant, with standard 1.27 mm pitch and 7.4–7.6 mm body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLK/IN) | Clock input or general logic input | Direct-pin clock source for any flip-flop; enables mixed-clock-domain designs without product-term overhead. |
| 2–12, 23–24 (IN) | Dedicated input pins | 12 total array inputs; all 22 logic pins usable as inputs; supports full 22V10 superset compatibility. |
| 13 (GND) | Ground reference | Single ground pin; requires solid PCB grounding to maintain signal integrity across 20 MHz+ operation. |
| 14–22 (I/O) | Bi-directional I/O buffers | 10 pins support input/output/bidirectional modes; each has independent output-enable product term and feedback path. |
| 24 (VCC) | +5V supply | Single 5V supply rail; decoupling capacitor required near pin to suppress switching noise from 171 product terms. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Pin-keeper Circuits | Eliminates need for external pull-up resistors on unused I/Os, reducing BOM count and board space while preventing floating-induced shoot-through current. |
| Dual Clocking Architecture | Per-flip-flop selection between product-term clocks (flexible edge-triggered control) and direct pin clocking (minimal latency for critical paths). |
| Asynchronous Reset per Flip-flop | Enables deterministic initialization of individual state elements without global reset propagation delay or timing skew. |
| Power-up Reset Function | Automatically resets all registers to low state at VCC ≥ 2.0 V, ensuring known initial state for state machines without external POR circuitry. |
| Preload Capability | Allows asynchronous forcing of high/low into any register via I/O pin voltage during 10.25–10.75 V pulse on select pin, simplifying boundary-scan test pattern generation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complex PLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-10PU | Same 24-pin PDIP package; identical electrical specs; no thermal derating required for industrial use. | Preferred for through-hole prototyping or legacy wave-solder assembly; lacks SOIC's space efficiency. | Select when mechanical mounting or hand-soldering is required; otherwise, ATF750C-10SU-T offers superior density and thermal performance. |
| ATF750C-10JU | 28-pin PLCC package; adds 4 extra I/O pins; same speed grade and industrial temp rating. | Suitable for designs needing expanded I/O count without changing logic architecture or JEDEC programming flow. | Choose when board layout allows larger footprint and additional I/O is needed; not pin-compatible with ATF750C-10SU-T. |
Compared with ATF750C-10PU and ATF750C-10JU, the ATF750C-10SU-T delivers identical logic performance and industrial temperature support in the smallest 24-pin surface-mount form factor, optimizing PCB area and reflow compatibility while maintaining full software and JEDEC file interchangeability.

The ATF750C series was designed as a high-density, electrically-erasable CPLD family targeting 5V system integration, offering backward compatibility with 22V10 and ATV750 while adding D/T flip-flops, pin-keeper logic, and enhanced clocking flexibility.
FAQ
What is the maximum operating frequency of the ATF750C-10SU-T in a no-feedback configuration?
The ATF750C-10SU-T achieves a maximum operating frequency of 142 MHz in no-feedback mode, calculated as 1/tP where tP (clock period) is 7 ns minimum. This value is confirmed in the AC Characteristics table under "No Feedback" for the -10 speed grade and applies directly to the ATF750C-10SU-T under 5V ±5% supply and commercial temperature conditions.
Does the ATF750C-10SU-T support both D-type and T-type flip-flops in the same design?
Yes, the ATF750C-10SU-T allows each of its 20 flip-flops to be individually configured as either D-type or T-type via fuse programming. This capability is documented in Section 23 and enables efficient synthesis of JK or SR flip-flops within a single ATF750C-10SU-T device without external logic.
Is the ATF750C-10SU-T pin-compatible with the older ATV750B/L devices?
Yes, the ATF750C-10SU-T is a direct replacement for ATV750B/L in the same 24-pin SOIC package. Section 25 explicitly states it is a "direct replacement" and supports cross-programming using ATV750B JEDEC files, preserving existing PCB layouts and firmware toolchains.
What is the purpose of the pin-keeper circuit in the ATF750C-10SU-T, and how is it enabled?
Pin-keeper circuits in the ATF750C-10SU-T hold unused input or I/O pins at their last driven logic level, preventing floating states that cause noise and excess current. Enabled via software compiler mode selection (e.g., V750CPPK for SOIC), it is controlled during JEDEC file generation-not by hardware straps-and eliminates external pull-up resistors.
How does the power-up reset function behave in the ATF750C-10SU-T, and what system-level conditions must be met?
The ATF750C-10SU-T automatically resets all registers to low when VCC crosses 2.0–4.5 V (VRST), with 600–1000 ns delay (tPR). To ensure reliable operation, the VCC ramp must be monotonic, input/feedback setup times must be met before clock activation, and the clock signal must remain stable during tPR-requirements specified in Section 21.
