Product details
Overview
ATF750C-15SC from Atmel is a high-performance, electrically-erasable complex programmable logic device (CPLD) with 20 registered outputs, 42 array inputs, and 171 total product terms. It delivers 15 ns maximum pin-to-pin delay at 5V operation, supports D- or T-type flip-flop configuration per register, and features programmable pin-keeper circuits for floating I/O stabilization. It is used in industrial control logic replacement, legacy PLD upgrades, and embedded state-machine implementations.
For engineers reviewing the ATF750C-15SC datasheet, ATF750C-15SC pinout, ATF750C-15SC application, or ATF750C-15SC equivalent, key selection criteria include its 24-pin SOIC package compatibility, 5V ±10% supply tolerance, -40°C to +85°C industrial temperature range, and backward compatibility with ATV750B/BL and ATV750/L JEDEC files.
Technical Context
The ATF750C-15SC implements a reprogrammable CMOS PLD architecture derived from the 22V10, extended with 20 individually configurable D/T flip-flops, dual-clocking options (product-term or direct input pin), and independent feedback paths for all registers. Its 171 product terms are distributed across 20 sum terms (2 per output), with variable allocation of 4–8 product terms per sum term.
It supports synchronous preset across all 20 registers and individual asynchronous reset per flip-flop. Power-up reset ensures deterministic low-state initialization of registers, and preload functionality enables asynchronous register loading via I/O pins during test cycles - critical for boundary-scan and functional verification.
Key Specifications

Pinout & Package
ATF750C-15SC is supplied in a 24-lead plastic gull-wing small outline (SOIC) package (24S), 0.300" body width, JEDEC MS-012 compliant, with 1.27 mm lead pitch. Pin 1 is marked by a beveled corner; pin 12 is GND, pin 13 is VCC, and pin 1 is CLK/IN.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Primary clock input or general-purpose logic input; selectable as direct clock source for any flip-flop. |

| 12 | GND | Ground reference for all logic and I/O circuitry; decoupling required within 10 mm of pin. |
| 13 | VCC | +5V ±10% supply; requires local 0.1 µF ceramic bypass capacitor adjacent to pin. |
Key Features

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 speed grade (15 ns), but in 24-lead PDIP package instead of SOIC; identical electrical specs and JEDEC file support. | Preferred for through-hole prototyping or legacy board repair where SOIC footprint is unavailable. | Select when mechanical compatibility with existing DIP sockets or wave-solder assembly is required. |
| ATF750CL-15SU | Low-power variant with 1 mA standby current (vs 135–190 mA for ATF750C-15SC); same 15 ns speed and SOIC package. | Suitable for battery-powered or thermally constrained applications where active power dominates system budget. | Choose only if standby current reduction is prioritized over worst-case dynamic current margin. |
Compared with ATF750C-15PU and ATF750CL-15SU, the ATF750C-15SC offers optimal balance of industrial temperature support, surface-mount compatibility, and full-speed performance without standby current trade-offs - making it the default choice for new industrial designs requiring 24-pin CPLD density.

FAQ
What is the operating voltage range for the ATF750C-15SC?
The ATF750C-15SC operates across 5V ±10%, i.e., 4.5V to 5.5V. This matches legacy TTL/CMOS 5V systems and eliminates need for voltage translation. The device draws 135–190 mA in standby under industrial conditions, and its DC characteristics (VIL, VIH, VOL, VOH) are fully specified across this range per the Atmel 0776L datasheet.
Is the ATF750C-15SC pin-compatible with the ATV750B series?
Yes - the ATF750C-15SC is a direct replacement for the ATV750B/BL in the same 24-pin SOIC package. It supports identical JEDEC programming files (V750B mode), retains the same pinout and logic architecture, and adds enhancements like T-type flip-flops and pin-keeper circuits that remain disabled unless explicitly enabled in the compiler.
Does the ATF750C-15SC support in-system programming?
No - the ATF750C-15SC requires external UV-erasable or parallel programmer (e.g., Atmel ATDH1200) and does not support ISP or JTAG. Programming is performed via standard 5V parallel interface using JEDEC files; security fuse prevents unauthorized readback once programmed.
What is the purpose of the pin-keeper circuit in the ATF750C-15SC?
The pin-keeper circuit in the ATF750C-15SC 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 per-pin in the WinCUPL compiler, it eliminates external pull-up/down resistors and reduces static power consumption in partially utilized designs.
How does the power-up reset function in the ATF750C-15SC?
The ATF750C-15SC performs automatic power-up reset: when VCC crosses VRST (2.0–4.5 V), all 20 registers initialize to low state within 600–1000 ns. This guarantees known startup behavior for state machines. For reliability, VCC must rise monotonically, and clock inputs must remain stable for tPR after reset assertion.
