Product details
Overview
ATF750CL-15SC from Atmel is a low-power, electrically-erasable complex programmable logic device (CPLD) with 20 D/T-type flip-flops, 171 product terms, and 20 sum terms. It operates at 5V ±10%, delivers 15 ns pin-to-pin delay, and supports industrial temperature range (–40°C to +85°C) in 24-pin SOIC package. It enables compact state-machine implementation in battery-powered control systems.
For engineers reviewing the ATF750CL-15SC datasheet, ATF750CL-15SC pinout, ATF750CL-15SC application, or ATF750CL-15SC equivalent, key selection criteria include its 1 mA standby current, programmable pin-keeper circuits, dual clocking modes (product-term or input-pin), asynchronous reset per flip-flop, and compatibility with ATV750B/BL legacy designs.
Technical Context
The ATF750CL-15SC implements a high-density PLD architecture derived from the 22V10, extended with 42 array inputs and full feedback routing-each of its 20 flip-flops feeds back independently into the logic array. Its dual clocking scheme allows individual flip-flops to be driven either by dedicated product-term clocks or directly from CLK/IN pin (Pin 1), enabling mixed-clock-domain logic within one device.
It features programmable pin-keeper circuits on all I/O and input pins to prevent floating states without external pull-ups, plus synchronous preset for all registers and individual asynchronous reset per flip-flop. Power-up reset ensures deterministic low-state initialization of all registers when VCC crosses 2.0–4.5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15SU | Same logic architecture and pinout, but standard-power variant (125–190 mA ICC vs. 0.12–0.15 mA) | Not suitable for battery operation; preferred where thermal headroom exists and legacy power budget allows | Select only if system-level power budget permits higher quiescent draw and no battery constraints exist |
| ATF750CL-15PU | Identical electrical specs and speed grade, but in 24-pin PDIP (24P3) instead of SOIC (24S) | Used in through-hole prototyping or legacy repair; lacks surface-mount manufacturability and thermal performance | Choose for hand-soldered prototypes or field replacements where SOIC footprint is unavailable |
Compared with ATF750C-15SU and ATF750CL-15PU, the ATF750CL-15SC uniquely combines industrial temperature rating, ultra-low standby current, and SOIC packaging - making it the sole option for space-constrained, battery-backed industrial controllers requiring long-term reliability and automated assembly.

FAQ
What is the maximum operating frequency supported by the ATF750CL-15SC?
The ATF750CL-15SC supports up to 50 MHz with external feedback (1/(tS + tCO)) and 62 MHz with internal feedback (1/(tSF + tCF)), based on its 15 ns propagation delay and specified setup/hold times. These figures assume proper PCB layout, 5V ±10% supply, and industrial temperature conditions - actual system frequency depends on logic depth and routing congestion. The ATF750CL-15SC achieves this while maintaining only 0.12–0.15 mA standby current.
Does the ATF750CL-15SC require external pull-up resistors on unused I/O pins?
No. The ATF750CL-15SC includes programmable pin-keeper circuits on all input and I/O pins. When enabled, these circuits hold the last driven logic state (high or low) after the pin floats - eliminating the need for external pull-ups and their associated board area and DC power loss. Pin-keeper activation is controlled during design compilation in Atmel WinCUPL or third-party tools supporting V750 device definitions.
Can the ATF750CL-15SC replace an older ATV750B in an existing design?
Yes - the ATF750CL-15SC is backward compatible with ATV750B/BL and ATV750/L devices. Using the "V750B" compiler mode generates JEDEC files compatible with legacy ATV750B fuse maps, preserving identical functionality and timing. No PCB changes are required, though users should verify voltage tolerance and thermal margins since the ATF750CL-15SC draws significantly less current than the ATV750B.
What package type is used for the ATF750CL-15SC?
The ATF750CL-15SC uses a 24-lead plastic gull-wing small outline (SOIC) package, designated as 24S per Atmel's ordering nomenclature. It measures 15.4 mm × 7.6 mm with 1.27 mm lead pitch, complies with RoHS and Pb-free requirements, and is optimized for automated SMT assembly in industrial-grade environments.
How does the power-up reset function in the ATF750CL-15SC?
The ATF750CL-15SC performs automatic power-up reset: when VCC rises monotonically and crosses the 2.0–4.5 V threshold (VRST), all 20 registers are asynchronously forced to low state within 600–1000 ns (tPR). This ensures deterministic initialization of state machines without external reset ICs. To guarantee reliable reset, the VCC ramp must be monotonic, and clock inputs must remain stable during tPR - design guidelines are detailed in section 21 of the datasheet.
