EPF10K50STC144-3 Overview

The Altera EPF10K50STC144-3 is a member of the FLEX 10KS series of high-density SRAM-based Field-Programmable Gate Arrays (FPGAs), providing 50,000 typical gates, 2,880 logic elements, and 40,960 RAM bits in a 144-pin TQFP commercial-grade package. According to the manufacturer product description, the device integrates 102 user I/Os, operates from a 2.5V core supply with 5.0V-tolerant I/O, and supports an internal operating frequency up to 166.67 MHz. The trailing -3 speed grade denotes a faster propagation delay bin than the -2 or -1 grades of the same family.

A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. The FLEX 10KS architecture is a hierarchical SRAM-based PLD that combines fine-grain logic elements (LEs) grouped into Logic Array Blocks (LABs) with embedded array blocks (EABs) for memory functions. Within the broader taxonomy, the FLEX 10KS sits below modern Cyclone and Stratix families but above simple CPLDs, targeting glue-logic, bus-bridging, and medium-density state-machine designs.

Key features include 360 LABs, 102 maximum user I/Os, JTAG IEEE Std. 1149.1 boundary-scan support built-in, and on-chip configuration memory. The 144-LQFP (also referenced as LFQFP / TQFP) package is a plastic gull-wing surface-mount form factor rated for commercial operating temperature. The SRAM-based configuration is volatile, requiring an external configuration device (EPC) at power-up. A built-in Joint Test Action Group (JTAG) boundary-scan test circuit is compliant with IEEE Std. 1149.1-1990 and consumes no additional device logic.

The EPF10K50STC144-3 -3 speed grade offers tighter propagation delay than the -2 grade of the same family, making it preferred for designs that approach the upper frequency ceiling of 166.67 MHz. The architecture is implemented in a 0.22 um CMOS process, and the device is intended for commercial (0C to 70C) operating environments.

Typical applications include telecommunications interface cards, industrial control and bridging logic, mid-density bus controllers, and legacy system upgrades. Design considerations for this device include mandatory configuration ROM selection (EPC1/EPC2 family), careful power-supply sequencing of 2.5V core and 5.0V I/O rails, and I/O bank planning against the available 102 user pins. Note: the FLEX 10K family is mature and was succeeded by ACEX 1K, Cyclone, and MAX families in the Altera (now Intel PSG) roadmap.
