EPF10K50STC144-2 Tóm tắt

The Intel (formerly Altera) EPF10K50STC144-2 is a member of the FLEX-10KS family of Field Programmable Gate Arrays, delivering 50,000 typical gate density with 2,880 logic elements and 40,960 bits of embedded SRAM in a 144-pin TQFP package. Per the manufacturer datasheet, the device provides 102 user I/O pins, 360 Logic Array Blocks (LABs), and a maximum internal frequency of 66.67 MHz with 0.6 ns propagation delay.

A Field Programmable Gate Array (FPGA) is a type of Programmable Logic Device (PLD) that combines configurable logic blocks, programmable interconnect, and I/O cells on a single semiconductor die. The FLEX-10KS architecture sits within the broader hierarchy: PLD -> FPGA -> Complex Programmable Logic Device (CPLD) hybrid family. The FLEX-10KS is notable as one of the first System-on-a-Programmable-Chip (SOPC) capable families, integrating an embedded array block for RAM and ROM functions alongside the logic array.

Key features include in-system programmability via SRAM configuration cells (allowing reconfiguration without removing the device), support for multiple I/O standards (LVTTL, LVCMOS, PCI), and an internal frequency specification of 66.67 MHz. The device operates on a 5.0 V core supply and supports JTAG-based boundary-scan testing per IEEE 1149.1. The package is a 144-pin Low-profile Fine-pitch Quad Flat Pack (LQFP/TQFP), surface mount, gull-wing lead form.

The FLEX-10KS architecture uses a CMOS logic fabric with continuous interconnect routing channels between LABs. Each LAB contains ten Logic Elements (LEs), each comprising a 4-input look-up table, a programmable register, and a dedicated carry chain. The embedded array blocks (EABs) provide 2 Kbit of dual-port RAM per block and can be cascaded to form larger memory structures, which was a distinctive feature at the time of introduction.

Typical applications include glue logic replacement, custom interface bridging (e.g., PCI to legacy bus), industrial control systems, telecommunications line cards, and prototype ASIC emulation. The 102 I/O count is well suited to designs requiring moderate external connectivity, such as multi-port memory controllers or parallel data acquisition systems.

When designing with the EPF10K50STC144-2, engineers should pay attention to configuration mode selection (Passive Serial, Passive Parallel Synchronous, Passive Parallel Asynchronous, or JTAG) and ensure the nCONFIG and nSTATUS pins have proper pull-up resistors during power-up sequencing. The SRAM-based configuration means the device must be reconfigured on every power-up unless an external configuration memory is used.
