EPF10K40RC240-4N Ringkasan

The Altera (Intel) EPF10K40RC240-4N is a FLEX 10K family embedded programmable logic device (PLD) delivering 40,000 typical gates and 2,304 logic elements (cells) with 16,384 bits of embedded memory, packaged in a 240-pin RQFP with exposed pad. It supports up to 189 user I/Os and operates at a maximum internal frequency of 125 MHz on a 0.42 µm CMOS process at 5 V supply.

An FPGA (Field Programmable Gate Array) is a programmable logic device whose architecture consists of an array of configurable logic blocks (LABs) interconnected by a programmable routing fabric and surrounded by programmable I/O cells. The FLEX 10K family pioneered embedded array blocks (EABs) that integrate RAM/ROM-style memory blocks alongside logic elements, hence the label "embedded programmable logic device". Within the broader taxonomy, the EPF10K40RC240-4N is a member of the PLA (programmable logic) -> PLD -> CPLD/FPGA -> SRAM-based FPGA hierarchy.

Key features include 288 logic array blocks (LABs), 189 maximum user I/Os, 5 V VCCINT/VCCIO operation, JTAG (IEEE 1149.1) boundary-scan testing support, in-system programmability via the Altera ByteBlasterMV or BitBlaster cable, and 0.42 µm CMOS technology. The "-4" speed grade places it in the moderate-performance tier within the FLEX 10K family, and the "N" suffix indicates a lead-free / RoHS-compliant commercial-grade part rated for 0 °C to 85 °C operation.

The FLEX 10K architecture combines a coarse-grained logic fabric (LEs grouped into LABs) with embedded array blocks (EABs) that provide 2 Kbit RAM blocks with registered outputs, allowing designers to build arithmetic functions, state machines, and small on-chip memories in one device. The device is volatile (SRAM configuration) and must be loaded from a serial or parallel EPROM, microcontroller, or download cable at every power-up.

Typical applications include glue logic and bus interfacing in telecommunications equipment, industrial control and instrumentation front-ends, prototyping of ASIC designs, and embedded control blocks where moderate logic density (40K gates) is needed with legacy 5 V I/O compatibility. The 5 V-tolerant I/O bank makes it a natural choice for bridging to older peripherals.

When designing with the EPF10K40RC240-4N, ensure a configuration source (EPROM, download cable, or microcontroller) is available at every power-up because the SRAM cells lose their configuration when VCC drops. Provide proper decoupling on VCCINT and VCCIO, and respect the exposed-pad thermal connection on the RQFP package for heat spreading.
