Product details
Overview
ATF750C-10SC from Atmel is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) in a 24-pin SOIC package, delivering 7.5 ns pin-to-pin delay at 5V operation, 20 D/T-type flip-flops, and 171 product terms for state-machine and combinatorial logic implementation in industrial control and legacy system upgrades.
For engineers reviewing the ATF750C-10SC datasheet, ATF750C-10SC pinout, ATF750C-10SC application, or ATF750C-10SC equivalent, this device serves as a speed- and feature-enhanced replacement for ATV750B/BL and ATV750/L in 24-pin PLD-based designs requiring reprogrammability, pin-keeper I/O, and dual-clocking flexibility without PCB redesign.
Technical Context
The ATF750C-10SC implements a 22-input, 20-output CPLD architecture with a unified programmable interconnect array feeding 20 individually configurable D- or T-type flip-flops - each with dedicated product-term clock, asynchronous reset, and synchronous preset. Its logic array supports up to eight product terms per sum term across 20 outputs.
It features dual clocking modes: product-term-derived clocks for flexible timing control and direct input-pin clocking (CLK/IN on Pin 1) for high-speed synchronous paths. All 20 flip-flop outputs feed back into the array, enabling buried logic and full register utilization without external routing.
Key Specifications

|---|---|
| Propagation Delay (tPD) | 7.5 ns max - ensures sub-10 ns combinational path timing for high-speed control logic |
| Logic Density | 171 product terms, 20 sum terms, 20 flip-flops - replaces >1000 usable gates in 24-pin footprint |
| Supply Voltage | 5V ±5% - compatible with legacy TTL/CMOS 5V systems without level-shifting |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments including motor drives and PLC modules |
| Reprogrammability | 1000 erase/write cycles with 20-year data retention - supports field firmware updates and design iteration |
| I/O Flexibility | 10 bi-directional I/O pins with programmable pin-keeper - eliminates external pull-ups and prevents floating inputs |

Pinout & Package
ATF750C-10SC is housed in a 24-lead plastic gull-wing small outline (SOIC) package (24S), 0.300" body width, JEDEC MS-012 compliant, with standard 1.27 mm pitch and 7.4–7.6 mm body depth.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (CLK/IN) | Input Clock or General Logic Input | Direct pin-controlled clock source for high-speed register paths; also functions as standard input when not used as clock |
| Pins 2–12, 24 | Logic Inputs (IN) | 12 dedicated input pins supporting setup/hold timing for both combinatorial and registered paths |
| Pins 13–22 | Bi-directional I/O (I/O) | 10 fully programmable I/Os with independent output enable, pin-keeper, and feedback capability |
| Pin 14 | Ground (GND) | Primary power return reference; decoupling capacitor placement critical for noise immunity |
| Pin 23 | +5V Supply (VCC) | Main power rail; requires local 0.1 µF ceramic bypass near pin for stable high-frequency operation |
Key Features
| Feature | Design Value |
|---|---|
| D- or T-type flip-flop per register | Enables efficient JK/SR synthesis and reduces product-term usage for sequential logic |
| Programmable pin-keeper on all I/Os | Eliminates need for external pull-up resistors and associated DC power loss in unused I/O states |
| Individual product-term clock & reset per flip-flop | Allows mixed-clock-domain state machines (e.g., UART baud generator + PWM controller) in single device |
| Power-up reset with guaranteed low-state initialization | Ensures deterministic startup for safety-critical control sequences without external reset circuitry |
| Asynchronous preload via I/O pins | Simplifies boundary-scan testing by allowing forced register states independent of clock polarity |

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 core logic, identical 7.5 ns tPD, but in PDIP (24P3) package instead of SOIC | Preferred for through-hole prototyping or legacy wave-solder assembly; lacks SOIC thermal performance | Select when manual soldering, breadboarding, or compatibility with older 24-pin DIP sockets is required |
| ATF750C-10SU | Identical electrical specs and SOIC packaging, but rated for industrial temperature range (-40°C to +85°C) vs. commercial (0°C to 70°C) | Required for deployment in uncontrolled ambient environments such as factory floors or outdoor enclosures | Choose for production units operating outside climate-controlled labs or offices |
Compared with ATF750C-10PU and ATF750C-10SU, the ATF750C-10SC offers identical logic performance and SOIC packaging optimized for surface-mount volume production, with commercial-temperature qualification suitable for lab validation, benchtop instruments, and indoor embedded systems where thermal margin exceeds 30°C.

FAQ
What is the maximum operating frequency of the ATF750C-10SC?
The ATF750C-10SC achieves up to 95 MHz maximum operating frequency under external feedback conditions (1/(tSS + tCOS)), validated at 5V ±5% and 25°C. This is derived from its 7.5 ns input setup time and 6.5 ns clock-to-output delay using pin-clock mode. Actual system frequency depends on logic depth and feedback path routing; internal feedback yields 133 MHz, while no-feedback operation reaches 142 MHz. The ATF750C-10SC maintains these speeds across its commercial temperature range.
Is the ATF750C-10SC pin-compatible with the ATV750B/L series?
Yes, the ATF750C-10SC is a direct functional and pin-compatible replacement for the ATV750B/L series in 24-pin SOIC packages. It retains identical pinout, voltage levels, and JEDEC fuse mapping for backward compatibility. When programmed with ATV750-compatible JEDEC files (V750B mode), the ATF750C-10SC operates as a speed upgrade with identical functionality - making it ideal for drop-in replacements in existing ATV750B/L designs.
Does the ATF750C-10SC support in-system programming?
No, the ATF750C-10SC does not support in-system programming (ISP). It requires external parallel programming via standard JEDEC-compatible programmers (e.g., Data I/O PS-200, BP Microsystems) using VPP = 10.5V. Programming occurs off-board, after soldering. However, its 1000 erase/write cycles and 20-year data retention allow multiple field reprogramming events when removed and reprogrammed externally.
What is the purpose of the pin-keeper function on the ATF750C-10SC?
The pin-keeper function on the ATF750C-10SC actively holds unused input or I/O pins at their last driven logic state (high or low), preventing floating nodes that cause shoot-through current and EMI. Enabled via software compiler selection (e.g., V750CPPK), it eliminates external pull-up/down resistors and associated power loss - particularly valuable in low-power industrial sensors and battery-backed systems where leakage must be minimized.
Can the ATF750C-10SC be used in automotive applications?
No, the ATF750C-10SC is not qualified for automotive applications. Atmel explicitly states in its datasheet disclaimer that its products "are not intended, authorized, or warranted for use as components in applications intended to support or sustain life" and "are not suitable for, and shall not be used in, automotive applications." The ATF750C-10SC is rated only for commercial (0°C to 70°C) and industrial (-40°C to +85°C) temperature ranges, lacking AEC-Q100 qualification, extended temperature coverage, or automotive-grade reliability screening required for vehicle systems.
