Product details
Overview
ATF750C-10SU from Atmel is a high-speed, electrically-erasable Complex Programmable Logic Device (CPLD) in a 24-pin SOIC package, featuring 20 D/T-type flip-flops, 171 product terms, 20 sum terms, and 7.5 ns pin-to-pin delay at 5V operation. It supports programmable pin-keeper circuits, individual product-term or input-pin clocking per flip-flop, and operates across industrial temperature range (–40°C to +85°C). It replaces legacy ATV750B/L devices in logic-intensive embedded control applications.
For engineers reviewing the ATF750C-10SU datasheet, ATF750C-10SU pinout, ATF750C-10SU application, or ATF750C-10SU equivalent, this page delivers verified timing specs (tPD = 7.5 ns), I/O flexibility (10 bi-directional pins), power metrics (ICC = 135–190 mA standby), logic architecture (22V10 superset with enhanced feedback paths), and real-world migration guidance from ATV750 series.
Technical Context
The ATF750C-10SU implements a reprogrammable CMOS PLD architecture with 42 array inputs feeding a 171-product-term logic array, enabling up to 20 registered outputs. Each of its 20 flip-flops is individually configurable as D- or T-type and receives dedicated asynchronous reset, synchronous preset, and clock enable via independent product terms.
Its dual-clocking capability allows per-flip-flop selection between product-term-derived clocks or direct input-pin clocking (CLK/IN on Pin 1), supporting mixed-speed state machines. All 20 registers feed back into the array, and 10 are available as I/O pins-enabling true bi-directional logic with independent output-enable product terms per pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
ATF750C-10SU is housed in a 24-lead, 0.300" wide Plastic Gull Wing Small Outline (SOIC) package (24S), compliant with JEDEC MS-012. Pin 1 is marked by a beveled corner; body width is 7.4–7.6 mm, lead pitch is 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLK/IN) | Input clock or logic input | Selectable as global clock source for pin-controlled flip-flop clocking; also functions as general-purpose input |
| 2–12, 23 | IN | 11 dedicated logic inputs; all support pin-keeper circuitry to prevent floating and reduce noise |
| 13 | GND | Ground reference for all internal logic and I/O buffers |
| 14–22 | I/O | 10 bi-directional pins; each has programmable output enable and independent feedback path to logic array |
| 24 | VCC | +5V power supply; decoupling required within 1 cm for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| D/T-type flip-flop selection | Each of 20 registers configurable as D- or T-type - enables efficient JK/SR synthesis and optimal product-term usage |
| Programmable pin-keeper | Eliminates need for external pull-ups on unused I/Os - reduces BOM count and DC power draw in idle states |
| Individual clock source per flip-flop | Supports mixed-clock-domain logic (e.g., UART baud rate generator + PWM timer) in single device |
| Power-up reset | Automatic register initialization at VCC > 2.0 V - ensures deterministic state-machine startup without external reset IC |
| Security fuse | Single-bit protection prevents unauthorized JEDEC file readback - critical for IP-sensitive firmware implementations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-10PU | Same logic architecture and speed grade (7.5 ns), but in 24-lead PDIP package instead of SOIC | Preferred for through-hole prototyping or legacy wave-solder assembly lines | Select when mechanical mounting or hand-soldering is required; same JEDEC file and programming flow |
| ATF750C-10JU | Identical electrical specs and logic capacity, but in 28-lead PLCC package (28J) with different pinout and thermal profile | Suitable for higher I/O count needs or existing PLCC socket infrastructure | Choose only if board layout accommodates 28-pin footprint; requires pin mapping adjustment in design |
Compared with ATF750C-10PU and ATF750C-10JU, the ATF750C-10SU offers the smallest PCB footprint (24S SOIC), best thermal performance for surface-mount reflow, and direct compatibility with modern automated assembly processes-making it optimal for volume production of space-constrained industrial controllers.

FAQ
What is the maximum operating frequency of the ATF750C-10SU under external feedback conditions?
The ATF750C-10SU achieves a maximum operating frequency of 95 MHz when using external feedback (1/(tS + tCO)), as specified in the AC Characteristics table for the –10 speed grade. This value assumes nominal 5V supply and 25°C ambient temperature. The ATF750C-10SU's 7.5 ns pin-to-pin delay and tight setup/hold timing enable reliable high-speed control logic implementation without external clock dividers or buffers.
Does the ATF750C-10SU support in-system programming (ISP)?
No, the ATF750C-10SU does not support in-system programming. It requires external parallel programming via a standard JEDEC programmer using the 14,504-fuse ATF750C configuration. Programming occurs before soldering, and the device retains its logic configuration for 20 years. The ATF750C-10SU is designed for pre-programmed deployment-not field updates-making it ideal for fixed-function industrial logic where security and stability are prioritized over reconfigurability.
How does the pin-keeper feature function on the ATF750C-10SU, and how is it enabled?
The pin-keeper circuit on the ATF750C-10SU maintains the last driven logic state (high or low) on any input or I/O pin when left floating, preventing noise-induced switching and reducing power consumption. It is enabled during design compilation by selecting the "V750CPPK" device mnemonic in Atmel WinCUPL software-not via hardware configuration. Once programmed, the pin-keeper remains active across power cycles. The ATF750C-10SU's pin-keeper eliminates external pull-up resistors in most applications.
Can the ATF750C-10SU replace an ATV750B-15PC directly on the same PCB?
Yes-the ATF750C-10SU is a direct functional and pin-compatible replacement for the ATV750B-15PC in 24-pin SOIC packages, provided the design uses only the ATV750 subset (no T-type flip-flops or pin-clocking features). Atmel confirms JEDEC file compatibility via V750B cross-programming mode. The ATF750C-10SU offers faster timing (7.5 ns vs. 15 ns), improved power-up reset behavior, and added pin-keeper capability-making it a validated speed and feature upgrade without layout changes.
What are the absolute maximum ratings for input voltage on the ATF750C-10SU?
The ATF750C-10SU has an absolute maximum input voltage rating of –2.0 V to +7.0 V with respect to ground, as defined in the Absolute Maximum Ratings table. This includes transient overshoot up to +7.0 V for pulses under 20 ns. For normal operation, input high voltage (VIH) must be ≥2.0 V and input low voltage (VIL) ≤0.8 V at 5V VCC. Exceeding these limits-even briefly-may cause permanent damage. The ATF750C-10SU's 2000V HBM ESD rating applies only to handling, not sustained overvoltage stress.
